Growing Kale

Kale plants grow large with frilly leaves in the garden

Full-sized kale plants are beautiful with big, frilly leaves that can be eaten whole in sandwiches, cut into salads, used as a garnish, or cooked alone or in soups.

Cold-hardy and resilient, kale is an easy member of the cabbage family to grow. You can set out plants quite early in spring as long as you protect the young plants from severe cold winds with a cover. They will grow steadily for months until the weather gets too warm. You’ll get a second chance to plant kale in the fall, when cool weather brings out a wonderfully sweet, nutty flavor that is unique to these cold-natured plants. Fall is the best time for growing kale in areas where winter doesn’t dip below the teens, or in a cold frame farther north, because the leaves are sweeter when they mature in cooler weather. In the kitchen, kale can be steamed, stir-fried, or substituted for spinach in omelets, casseroles, or even quesadillas. It’s a wonderful addition to smoothies, too.

Soil, Planting, and Care

Set out plants in spring 3 to 5 weeks before the last frost; in late summer, you can begin planting kale 6 to 8 weeks before the first frost for fall and winter harvests, and continue planting throughout the fall in zones 8, 9, and 10. Kale grows best in full sun, but will tolerate partial shade as well. Plants that receive fewer than 6 hours of sun daily will not be as stocky or leafy as those that get ample sun, but they will still be plenty edible! Like collards, kale likes fertile soil to grow fast and produce tender leaves. Enrich the soil with compost and fertilizer before setting out the seedlings. Apply fertilizer and lime according to test recommendations. If you forgo the soil test, work nitrogen-rich amendments such as blood meal, cottonseed meal, or composted manure into the ground before planting.

Kale being watered in the garden. Kale needs lots of water to make tender leaves.

Kale will produce the most tender leaves if the plants get plenty of moisture from the beginning.

The soil pH should be 6.5 to 6.8 to discourage clubroot disease, although the plants will grow fine in a pH of 6.2 to 6.8 if clubroot is not a problem in your garden. To be sure about your soil pH, test the soil with a do-it-yourself kit, or by using your regional Cooperative Extension office.

Kale is easy to plant. Set plants at the depth at which they are growing in the container. Space them 18 to 24 inches apart. The leaves will grow bigger if given a lot of space, but smaller leaves tend to be the most tender. After planting, water plants well and apply a liquid fertilizer such as Bonnie Herb & Vegetable Plant Food for excellent results.

At this point you may need to be patient, because spring-planted kale may stay small until slightly warmer soil temperatures trigger vigorous growth. Kale planted in late summer or early fall may sulk through spells of hot weather. Then, when conditions improve, the plants will take off, quickly multiplying in size.

Kale likes a nice, even supply of water, about 1 to 1.5 inches per week. You can measure how much water rain has provided by using a rain gauge in the garden. Mulch with compost, finely ground leaves, weed-free hay, straw, pine needles, or finely ground bark to keep the soil cool and moist and to keep down weeds. Mulching will also help keep the leaves free of splashing soil for a clean harvest.


Large pots of kale plants flower in warm weather in the garden

When the weather warms, your kale plants will send up flower stalks and produce pretty yellow flowers. The plants become ornamental in the garden, and you can cut the flowers for arrangements.

Kale often grows as a carefree crop, but there are several insects that like kale as much as people do. Velvety green cabbageworms often can be found chewing holes in kale leaves. The larvae of cabbage white butterflies, cabbageworms are more likely to feed on cabbage, broccoli, and cauliflower than to bother your kale.

Colorful black-and-orange harlequin bugs often show up on kale plants that are feeling the stresses of old age. Rather than fight the harlequins, most gardeners pull up and compost old plants if it is mid- to late summer. In late summer, the best way to protect young seedlings from these and other pests (like grasshoppers) is to cover them with row cover or some other lightweight fabric, such as wedding net (tulle). The covers can be removed in mid-fall, when pest populations usually drop dramatically.

Watch for outbreaks of gray-green cabbage aphids, which often gather in clusters within the folds of frilly kale leaves. Treat small problems with insecticidal soap. Pick off and discard badly infested leaves.

Harvest and Storage

This winter scene shows kale alongside leeks in a display of two of the garden’s most cold-hardy vegetables.

Like collards, kale leaves are sweetest in the fall, after they’ve been touched by a light frost. Pick the oldest leaves from the lowest section of the plants, discarding those that appear yellowed or ragged. Pick your way up the stalk, taking as many leaves as you like, as long as you leave at least 4 leaves intact at each plant’s top (or growing crown). Kale will produce new leaves all winter in zones 7 to 10. In climates where hard freezes are frequent, kale often survives winter with additional cold protection from thick mulch, row covers, or plastic tunnels. Overwintered plants will eventually bolt (producing yellow flowers) in spring, signaling that it’s time to remove them and make room for other crops. Wash the leaves thoroughly and store them in a plastic bag. You can eat the stems or discard them—it’s up to you. If you cook the kale, the stems will become more tender. Kale leaves will keep for several days in the fridge in a loose plastic produce bag.

Should I harvest leaves when they are young or wait until they grow larger?

It depends. Young leaves work great for salads, but if you’re planning to cook the greens, let leaves reach full size. Pick the largest leaves from the bottom and outside of the plant. Avoid picking or damaging the center of the plant where new leaves arise.

How long can I expect to harvest kale?

For many months. You can pick spring-planted kale all summer, but leaves may get tough and bitter when heat arrives. Quality improves again in fall and plants continue growing even winter in mild climates. Frost makes them taste sweeter, and plants are cold-hardy at least to the low 20s. The following spring, though, they will bolt. The same is true for fall-planted kale. Winterbor is an especially cold-hardy one that works well in cold weather. Gardeners in cold climates can enjoy it through winter in a cold frame.

Is there anything I can do to help kale leaves stay sweet?

Warm weather can make kale bitter and tough. While cool temperatures are the key to sweet leaves, you can help keep roots cool by mulching around plants. Making sure plants remain well watered also improves leaf flavor.

I picked kale last week and the patch still looks sparse. Is there anything I can do to jump-start growth?

Fertilize during the growing season for a steady supply of leaves. You can side dress plants with compost or blood meal, spray foliage with diluted fish emulsion, or water with a liquid fertilizer like Bonnie Herb & Vegetable Plant Food.

How long can I store harvested kale?

Kale stays crisp in the refrigerator for up to two weeks. Store it in an unsealed plastic bag with a damp paper towel.

Frost is predicted. Should I pick all the kale and store it?

Frost actually sweetens kale. This is the most cold-hardy of all vegetables and will take quite a few of the early frosts before a hard freeze, or “black frost” as it sometimes called, kills it in colder regions. In zones 7 and warmer it often continues to produce leaves all winter long.

Green worms are eating my kale. Can I spray anything that will kill the worms without hurting my family or pets?

Cabbage worm likes to eat kale. If you’ve noticed a white moth fluttering among the plants, that’s the source of your worms. Spray kale with Bacillus thuringiensis (Bt) to control the worms. Bt doesn’t affect humans or other wildlife. Bt targets worms, which die after ingesting it. After you spray Bt, worms may take a few bites from the leaves, but they’ll stop feeding and die in a few days. Spray any time you spot the moths among plants.


Rachel Whetten

Hi! I am growing kale in my garden (about 6 plants) and while it is green and not stunted, it is not very fluffy. I would say it is stretching or reaching, perhaps? Very stalking and not a lot of leaves. They get get plenty of sun (full sun). I usually grow tomatoes and basil only in this garden, so much so that I let my garden go fallow last year to enrich the soil. I planted everything with compost to provide more nutrients and I fed them plant-tone about 2 weeks ago. Is it possible my soil is just not acidic enough? Should I add more compost? Thanks! PS: let me know if I should send a photo somewhere!

Danielle Carroll

Hi Rachel,
If your kale is reaching, it may be trying to grow flowers and set seeds. When this happens, you will see the stalk growing thicker and taller towards the sky. This can happen if the temperatures warm up quickly from winter (or spring). If kale starts to bolt, it will flower, but there will not be much more foliage. The flowers are great – ornamental and pollinators love them. You can see a picture of kale flowering here, in the Bonnie Plants gardening library. -danielle, Bonnie Plants

Rachel Whetten

HI there,
It’s not doing that yet but it might! And I don’t want it to! We have actually had a relatively cool and wet spring (I am in NC). What else could be happening? Is there anything I can do to prevent the bolting? Thanks so much!

Danielle Carroll

Hi Rachel,
There is not a lot you can do to prevent bolting – the weather will determine that for us. You can keep the plants as healthy as possible by fertilizing, watering, mulching, and weeding. Healthy plants are one of the best ways to keep things from going wrong. You are welcomed to upload a picture to the Bonnie Plants Ask an Expert site so someone can get a better look. – danielle, Bonnie Plants


Wow that was strange. I just wrote an extremely long comment but after I clicked submit my comment
didn’t appear. Grrrr… well I’m not writing all that over again.

Anyways, just wanted to say superb blog!


Two years ago, my husband planted two of your kale plants. Despiste cold weather, and freezing temps, those two plants are still producing fresh kale! They’re blooming right now, but we’ll leave the stalks again, for the next season of fresh produce. They’re 3 to 3.5 feet tall, and very pretty! (We live in the Midlands of South Carolina.)


I plant kale in the 1st week of ugust . it grows until about now , the flowers are here , this is May 1 2013 . it has been growing for 9 months . In the winter it does nothing , but it is stil good to eat . Nashville Tn .


Hello. I cannot find an answer to this question online anywhere and hope you can help. I was given Hanover Salad as a seedling and now the 3″ tall seedling has sprouted yellow flowers. Do seedlings bolt or is this normal growth for this variety of kale? Thanks.

Danielle Carroll

Hi Susan,
Hanover salad or hanover kale is the common name for a plant which is not really a kale – same family, but more kin to canola and rape. Hopefully this will explain about the hanover kale you bought. -danielle, Bonnie Plants

Char Someone

I have limited gardening space. I would like to grow kale in containers. What soil mix would you recommend?

Danielle Carroll

Hi Char,
This is a great article in the Bonnie Plants library detailing what a good potting mix consists of. That’s a great question….good plants start with good soil. – Danielle, Bonnie Plants


hi! i live in greece, we dont have Kale here (!) so i ordered some seeds online, i grew them to seedlings but the moment i planted them out in the garden they started to bolt! can the weather have been too warm for them, eventhough it’s only March (60-70 F) ?

Danielle Carroll

Hi Anna,
How old were the seedlings when they were placed outside? It could have been a temperature change from seedling growth temperatures to outside temperature. Some varieties are are slower bolting than others. – Danielle, Bonnie Plants

Elli L.

Hi, I live in the Southern part of Florida and planted Winter borne Kale about a month ago. The leaves are at a smaller size compared to the pictures, but my main concern is that I have noticed tiny translucent-like insects on the back side of them. Also, there’s a trail of white on a few of the leaves as well. Why is this happening and how can I avoid this from happening?

Danielle Carroll

Hello Elli,
Leaf miners have found your kale! Leaf miners are the larval stage of certain flies and moths. Eggs are laid and the larvae bury inside the leaf and tunnel through. While the tunnels are not very attractive, leaf miners usually do not do permanent damage to the plants. The insects on the leaves could be aphids. You are welcome to send in a picture via Bonnie Plants Ask an Expert. Aphids cluster together on the backsides of plant leaves. Best to identify first, so here a picture from the North Carolina Extension System along with controls for home garden. Treat small problems with insecticidal soap. Pick off and discard badly infested leaves.

Linda Harris

I live in Atlanta and just bought some small kale plants for my garden. After reading some of your Artie’s, I am wondering if I have waited too late to start them?

Danielle Carroll

Hi Linda,
This is the planting guide for your area from your the Univeristy of Georgia Cooperative Extension. Looks like you are right on time. Now, let’s hope the weather is nice to us!
-Danielle, Bonnie Plants


Okay, my kale has started flowering. Now what do I do? Are there seeds I can harvest from it? Do I just dig it up in a few weeks? I live in north Texas so I know it won’t survive the summer heat outdoors.

Danielle Carroll

Hi Tammy,
Kale has beautiful flowers, but the flowers also signal the end of kale’s life cycle. Once it starts to flower or bolt, the harvestable leaves may become bitter or off flavor. You can harvest the flowers and toss them into your salad for more flavor and color or use the flowers in an arrangement. Time to replace the cool weather vegetable with warm weather ones in your garden.
-Danielle, Bonnie Plants


Hi. Approximately how many year is the life cycle of kale?

Danielle Carroll

Hi Ozzie,
Kale typically lasts one season. It thrives during the cool weather months and flowers (and sets seeds) as the weather warms. – danielle, Bonnie Plants

Nettie Marie

Hi there!

I have wonderful Kale growing in my garden that I planted last year. The stalks are about 2-3 feet tall. I am seeing new leaves starting to grow on the stalk of the previous picked leaves. I know that warm weather is coming and the stalks will go to flower. Will the lower leaves continue to grow on the stalks after it goes to seed?

Danielle Carroll

Kale flowers are so pretty. You can cut and use them in arrangements. However, once a plant starts producing seeds, the edible leaves become bitter and loose their good flavor.
-Danielle, Bonnie Plants

Nettie Marie

Can I cut off the flowering top and keep growing the Kale? It is still producing so nicely…..

Danielle Carroll

If you cut the first flowers off, it will immediately start trying to flower again. So you can cut the flowers off, but it will be a never ending process. Temperatures and the end of the plants life cycle are signaling the flowers at the expense of the leaves. Too bad we can’t grow kale year round!
-Danielle, Bonnie Plants

D. Hansen

I’m in WA , great kale country; my kale is 2 ft. high but has stopped growing leaves, and the stems are very thick, some even bulbous and weird-looking. Do I pull them up ( there are some tiny sprouts but they’re not doing anything) and start over in the spring with new plants? these look awful, and I will soon need a logging permit for them…

Mary Beth

Ha! A logging permit. This sounds unusual to me. I would start over with fresh new plants in the Spring. Make sure that you harvest from the bottom up and leave enough leaves on the plant at a time for it to prosper. ~Mary Beth, Bonnie Plants.

B. Jorgensen

I also live in WA and my kale is the same way. There seems to be what looks like small flower buds forming on the tops but the leaves are not bitter they are very sweet. These are ones I planted last spring and in about 2 weeks will be a year old. Other then bitterness do they ever get to where they are unsafe to eat? Like yours if I need to pull them will probably need a tractor and cable to get them out.

Danielle Carroll

The flavor changes with age and flower formation, but they are not unsafe to eat.

Baldwin W Walker

Hi to all. I am getting started in home gardening here in Sourthern California. Yucca Valley. I would like as much information as possible pertaining to growing Kale. I will be creating a 3-Foot Square on to of pure sand. Will try to send photo of the area of perposed garden. Hope to hear from you.
Thanking you in advance.


Mary Beth

Hi Wes,
Welcome to our gardening site! We strive to compile in-depth and step-by-step growing information here as you need in getting started. Also check out the “Gardening” section for a library of resources and our Facebook page for sharing pics and success stories. Kale is definitely the “it” veggie the past few years. Can you describe what you by “on pure sand?” Is that the base for your raised bed? The page here, “How to Grow Kale,” has detailed information from planting to harvest; make sure you click on all of the tabs for Troubleshooting and FAQs. Looking forward to seeing your garden. You can post links to photo accounts, or you can send us photos via Facebook, Customer Service, or Ask An Expert. ~Mary Beth, Bonnie Plants

Mary Beth

I received your photo, Wes. What a beautiful blank canvas for lots of raised beds! Nice wall, too. So, you have the sun you need and you’ll have the soil you require with adding fluffy, rich, raised beds. You’ll want to read this article to get started. Since you are building atop sand or hard ground, build deeper beds than 6 or 8″ so that you can also grow root crops and allow deeper root room for your garden. Most of the time one would till the ground to allow for penetration into the native soil, but instead, just go UP! After reading this article, click on many of the raised bed how-to articles for step by step instructions. ~Mary Beth, Bonnie Plants

Annette S.

Hi, I live in North Texas, and my kale plants look healthy, they just aren’t very large. They’ve been in the garden for almost 3 months. I have the curly leaf variety. leaves are only about 6-8″ long at most. they are very tender and tasty. Should the plants be much larger by now?

Mary Beth

Hi Annette,
Do you mean this variety with curly leaves? The photo of Winterbor, if that is what you have, is helpful to see in mature plant size for reference. Kale is a heavy feeder and can use a good dosage of fertilizer upon transplanting and then again several weeks later. Also, if you read within this article, we describe how fall-planted kale in warm weather areas will “sulk” until temperatures level out to its liking and it will soon take off. You’ll be able to grow kale throughout the winter where you are, so luckily you have plenty of time and opportunity for it to catch up! Keep us posted. ~Mary Beth, Bonnie Plants


Hello, I just moved to the Fayetteville NC area and I wanted to grow kale. Do you think I could plant them now, it’s the beginning of December? Should I do this outside or in the house? Or should I wait until it gets warmer? I’m looking forward to hearing your advice.


Mary Beth

Hi Montse,
If you have access to kale plants now, I think it’s worth a shot planting them. They are very cold hardy and even sweeten in frosts. Our article on These Plants Take a Chill will describe to you the range of cold temps that they withstand, and an article on covering with frost cloth will get you started for those extra low temps. Sure, it’s a little late from what is ideal, but I think it’s worth trying. ~Mary Beth, Bonnie Plants


A friend was telling me he won’t eat kale anymore
Because he noticed that the critters that visit
his garden won’t touch it, even in the dead of
winter when it’s the only thing sitting above
the snow. Can you tell me why other animals
won’t eat it? He says he has to follow nature’s
lead….I love kale, but also have to wonder why
other animals won’t eat it. Thanks.

Mary Beth

Hi Kathy,
That is very interesting. I wonder what type of kale? Perhaps that is the last thing on the buffet, given the choice, if it is a very fringed and curly-textured kale such as Winterbor? Deer will indeed eat all kale in sight if given the chance, so I’m not sure why his is repelling. Or are critters you reference more like rabbits and raccoons? I’d consider it lucky and harvest what was overlooked for my own kale chips or soups and thank the critters! 🙂 ~Mary Beth, Bonnie Plants


Hi, Bonnie Plants folks,

First of all, this website is SO useful. Thank you!

I’m growing kale at the moment in pots on my fire escape in Zone 6. The plants are a fall crop, so their stems are around 4-6 inches tall. I don’t have any garden space, but I’d like to try to overwinter them. Do you have any suggestions for me? Also, is bringing them in on cold nights a good idea?



Mary Beth

Hi Abby,
Thank you so much! You may also enjoy our regular e-newsletter with tips and techniques, or to join our Facebook page where we share photos, advice, recipes, and garden inspiration with our online family. Hope to see you there!
Kale is one of my favorite vegetables so I can understand why you want to grow it as long as you can. It’s pretty tolerant of cold temperatures and even tastes better after one or two frosts, as it sweetens the flavor. Our cool-season garden list shows you what endures a frost and how low they can go. Kale has grown happily through a couple of light snows in my garden, but if you experience a really snowy, freezing winter, it may be easier to bring your container indoors. Next season we’ll be selling a new variety for us that I’m personally excited to share with you; try Lacinato kale in addition to what you already see from Bonnie. Let us know how it grows! ~Mary Beth, Bonnie Plants



I am trying to grow Kale in my garden in N. Florida. I planted seeds in spring but they stayed less than two inches tall, I chalked it up to heat and herbivores. So I tried again about 6 weeks ago. I planted seedling that I sprouted in pots, I mixed compost into the soil before planting seedlings and I water them every 1-2 days. They are still tiny! Some only have one leaf yet. Why won’t my kale grow? More fertilizer? Less water? Help! I’m starting to make puns about how the seedlings are reKALEcitrant!

Thanks 🙂

Mary Beth

Hi Abigail,
Kale is a wonderful addition to your garden and I know that you’ll be pleased…once you get it growing large enough to eat! Many first-time gardeners have trouble with getting the perfect conditions for seed-starting, which is why we sell healthy “head starts” in seedling form. We do not currently sell seeds or have seed-starting instructions on our site. In your case, check that you are getting enough light to these little ones and I would hold off watering that much. This link can help you in more detail with your seed babies:

I have several Kale plants that I planted in June. I’ve harvested them through this entire hot Chicago summer without a problem, in fact I’ve had a hard time keeping up with them! It is starting to cool off now, (highs around 70 f, lows around 45 f) and they seem to be growing a little slower. Are they coming to the end of there life? Should I plant new kale for the winter crop? Since they reached maturity in the summer heat, will they be unable to acclimate to the cold? Or will I be able continue harvesting from these ones all winter?

I am still eating off of them now, they are just growing slower than they were earlier in the summer.

Thank you!

Mary Beth

Hi Anna,
Your kale will do well this fall and winter, too. In fact, it thrives in cooler temperatures and tastes sweeter after a few frosts. If your plants are healthy, keep them. Give them a second dose of plant food, such as our Bonnie Vegetable and Herb Plant Food. If you are harvesting leaf by leaf, just make sure to pick from the bottom up and it’ll continue to leaf out from the top. Of course, once you taste it after a few frosts, you may wish you planted a lot more, so don’t let me dissuade you from getting new, extra plants! 🙂 Enjoy.

hi i was wondering if it would be possible to grow kale from stem cuttings????????????

Mary Beth

That’s a lot of question marks! Hi Rawfoodistmum. We recommend planting our seedlings for the easiest jump start, or you can plant from seed acquired from another source. ~Mary Beth, Bonnie Plants


I grow many greens for my green smoothies. Kale is one of my favoeites. My question is: can I grow kale through the winter in a “greenhouse” setting? I have a basement with several windows on the south and west. Is that enough light or do I need to add a grow light? What kind of soil do you recommend?

Kelly Smith Trimble

Hi Geralyn,

Kale is a great plant with lots of nutritional value. It’s also one of the most cold-tolerant vegetable plants, so why not just grow it outside this fall and winter? I’d suggest planting outdoors unless there is some other reason you want to plant it indoors. Plant kale in good garden soil enriched with compost. Happy growing!

Kelly, Bonnie Plants


Hi, I’m a keen young gardener an have recently set up my first veggie garden & am growing Kale, my yard doesn’t get much sun so my Kale won’t get very big but it is about 10-15cm at the moment an whilst small it is very green an healthy so I’m happy
So my question is I have never grown or eaten Kale so I’m just wondering when is it ok to eat the leaves?i doubt it will ever get big enough to harvest a whole plant so is it ok to eat these small but perfectly formed leaves?

Kelly Smith Trimble

Hi Shalayne,

Yes, you can definitely just harvest the leaves! In fact, that’s exactly how you do harvest kale. Click above on the “Harvest & Storage” tab for more detailed information about how to pick and eat your kale. I hope you enjoy this tasty, nutritious veggie!

Kelly, Bonnie Plants

diane reimers

What do I do for my kale? It is now a foot tall but the insects are making lace of the leaves. Shall I cut them to the ground and will they grow more leaves? How do I prevent this from happening again.

Kelly Smith Trimble

Hi Diane,

It could be cabbage worms that are munching on your kale leaves. They will chew on any plants in the cabbage family, including kale. Click on the Troubleshooting tab on our Growing Cabbage page and you’ll see what they look like. You can pick them off by hand, or if they become a real problem, spray plants with Bt (Bacillus thuringiensis) according to label directions. You can remove the affected leaves but need to keep the growing crown (top and center) intact to get more leaves from the plant. Kale is a cool-season crop so the plant is likely to start going to seed (flowering) soon anyway in the warmer summer weather, unless you’re gardening in a very cool climate. At that point, you can let the plant flower (the yellow blooms are rather pretty) or take it out. I hope this helps. Happy growing!

Kelly, Bonnie Plants


I transplanted my kale in May. It has been producing great and I am still cutting leaves each week. It is now July in NJ and I am wondering how much longer will these plants produce this season.

Kelly Smith Trimble

Hi Geannine,

As the weather heats up, your kale plants will start to bolt, growing taller and producing yellow flowers. Exactly when this will happen depends on your specific climate and conditions. You can see kale bolting above in the “Troubleshooting” tab. Until then, keep on harvesting those tasty, healthy kale leaves! Happy growing!

Kelly, Bonnie Plants


If my kale survived all winter and now has flowers, does that mean it’s bad now?

Danielle Carroll

Hi Georgia,
It means that your kale is ending its life cycle, but it sounds like it has been a trooper for you througout the winter 🙂 It is very pretty once it starts flowering, and the flowers are pretty in arrangements. – Danielle, Bonnie Plants


i’m growning black kale, planted kale in may, will it grown in the summer or is it too hot to grown black kale in the summer, please help.

Kelly Smith Trimble

Hi Rosa,

Kale is as hardy vegetable plant, which means it can takes temperatures down to 25 degrees. Hardy and semi-hardy crops are usually grown in the cool-season garden and planted in early spring or late summer. Depending on where you live, it’s probably too warm to grow kale, and you may see the plant begin to bolt, or send up flowers, as weather heats up. You can leave the flowering plant in the garden (it’s actually quite pretty) but the leaves won’t be as tasty. You can read our article “Which Veggies for Which Season?” to learn more about what vegetables to plant when. Happy growing!

Kelly, Bonnie Plants

Kelly Smith

Hi Gregory,

That is so great to hear! I love kale. It’s so tasty and full of vitamins. Happy growing!
