Growing Collard Greens – Cousins Of Kale


What’s Easier Than Falling Off A Log?  Growing Collard Greens!Collard greens freshly picked.

If you’re not growing collard greens, you should be – if you are partial to all the healthy nutrition that leafy vegetables have to offer.

Originating in the Mediterranean region, Greeks were eating them along with kale a couple thousand years ago.

Besides Greece, collard greens are commonly found on dinner tables in a number of African countries – in southern Europe – in South America, mainly Brazil – and in the southern states of the U.S.A.


Packed With Loads Of Goodness

You name the vitamins or minerals – and, collards have them!  Just like kale, the most abundant nutritional elements are vitamins: A, B6, C, and K – and minerals: manganese and calcium.

In other words – they pack enough of a healthy punch to do the body good!


Eat ‘em Raw.  Eat ‘em Cooked.

Either way works for me.

Collard greens in a salad.

I sometimes whip up a salad of mixed greens that include mesclun, kale, spinach, and collard greens.  Adding some onions, olives, a handful of croutons, some cherry tomatoes, and a healthy dose of grated cheese and olive oil, complete the concoction – giving it a full, wholesome flavor!

Southern cooking is just not “southern” without a pot of collards simmering with some smoked meat – like ham hocks or turkey.  More commonly, fatback is used – which is the hard fat on the back of a pig under its skin – hence the name.

The thick leaves grow larger than dinner plates and, if harvested with care, the plants will continue to offer up new leaves to harvest throughout the growing season – at least until they bolt.  Then, if heirlooms were planted, seeds can be gathered for next year’s growin’ season.

The larger the leaves – the more customarily bitter the taste.  But, mixed with the right flavorings, their bitterness is easily masked.  A splash of vinegar and a little sugar helps the cause.

Gotta have cornbread with my collard greens.

Don’t forget the cornbread.  I can’t eat collard greens without it!  I use it to soak up the collard broth – also called pot liquor!  The broth has a ton of nutrients in it.

Did You Know?  New Year’s Day in the South – here in the U.S. of A. – is not complete without consuming whopping portions of collards, black-eyed peas, and cornbread!

Just don’t overcook those collards – unless you love the smell of rotten eggs.  Whew!  Nasty!  Overcooking brings out the devil in them – in the form of sulfur.  And, the smell will hang around in the kitchen for so long, you’ll be convinced that it is immortal!


Time To Cultivate Some Collards

In “The Best Organic Growing Seeds – For All Your Veggie Growing Needs”, the best collard seeds are listed – and, they are the most popular varieties – Tiger and Georgia.  Also listed is an Asian variety – Senposai – that closely resembles collard greens but, the leaves are larger and more tender.

For the most part, even though collards are fairly heat tolerant, they prefer their 6+ hours of sun in the morning and early afternoon – and some shade during the hotter late afternoon hours – if they’re planted in the spring and grow throughout the summer.

Planting these greens in the fall will yield more flavorful leaves because collards love the cold winter weather – and, they can survive an occasional light frost or, sometimes, even a snowfall.

Plant seeds directly into the garden after the last spring frost or, at least a month before the first fall frost.  I like to get a head start – a month or so in advance – by germinating collard seeds indoors and processing them through transplanting and hardening off before sticking them in my backyard garden.

Collard greens growing well.

  • Make sure to till the soil 6 inches deep.
  • Run a 1 inch deep furrow down each row – and, keep the rows a couple of feet apart.
  • Put down a half inch layer of Jim’s 50/50 soil mixture along the furrow.
  • Space seeds a couple inches apart and cover with another half inch layer of Jim’s soil mixture.
  • Water well and keep the furrows moist but not soggy until the seedlings start coming up – which takes anywhere from 1 to 3 weeks. Give the collards an inch of water per week to keep them happy.  A water sensor or probe is a great aid for making sure that the plants get enough water.
  • Once the second set of leaves appear, thin out the plants so that they are at least a half foot apart.
  • Lay down some soaker hose to irrigate them. Overhead watering should be avoided, if possible – unless it is done in the morning.  If the leaves are wet overnight, they are highly susceptible to getting fungal diseases.
  • Mulch around the collards to help keep the moisture in the soil – and discourage weed growth. Weeds will rob the plants of both water and nutrients – and, that is not a good thing as we all know.
  • Every 3 to 4 weeks, give them a little fertilizer for food. 10-10-10 fertilizer works very well and it is relatively inexpensive.

NOTE:  Many a time throughout my gardening years I have had limited space – and, I found that collard greens can be easily grown in a container garden.  But, make sure the container is large enough to hold a mature plant – a pot about 2 feet wide and 2 feet deep is best.


Picking The LeavesLarge collard green leaves ready to harvest.

Once the collard leaves are growing, you can pick them anytime.  I wait for a month after they sprout – to give their roots a chance to get a good firm hold in the ground.  It usually takes a month before the leaves get to the size of a dinner plate – which is about the dimension I like them best.

Pick the larger, outermost leaves – starting at the bottom and working towards the top.  Don’t bother with the smaller leaves.  Wait for them to grow up.  Continuing this harvesting method will produce an insurmountable amount of collard greens all the way through the growing season.


Preserving Collards Is As Easy As Growing Them!

Collards will stay fresh in the refrigerator for a week or two at best – as long as the temperature is just barely above freezing.  Most refrigerators operate at warmer temperatures so, 3 or 4 days is probably the collard greens “freshness threshold.”

For freezing, blanch the greens for 3 minutes in boiling water, shock them in a big bowl of ice water for 3 minutes, then bag, tag, and stick them in the freezer.  They’ll be good to eat for a year or two.

Canning collard greens will extend their life up to 3 or 4 years – if done properly.


Pests and Diseases

All the common pests for leafy greens will gorge themselves on collard greens, too.  These include aphids, cabbage loopers, flea beetles, leaf miners, and slugs.

To discourage these nasty crawlies organically, try growing some plants that repel bad bugs such as catnip, dill, garlic, fennel, nasturtiums, or peppermint – to name a few.

Beer traps work well for eliminating slugs.  Pour some stale beer into tuna cans and put them on the ground every few feet along the row.  Slugs love the beer yeast and will climb in for a drink – and drown.  End of story!

If the additional plants or the beer traps don’t do the job, the “plan B” defense is to use the best insecticide known to man, Ortho Flower, Fruit and Vegetable Insect Killer.



Fungal diseases such as leaf spot and downy mildew have a history of plaguing collards.  If the leaves start getting a powdery look or getting brown spots all over, hit them with a fungicide like Daconil or Physan 20.  Pull off the worst affected leaves and put them in a trash bag.  If leaf spot or mildew is caught early, these fungicides may save the plants.

If the disease overtakes the plant, the only option is to remove the whole thing – roots and all – bag it up, and leave it on the curb for the garbage collector.

Don’t keep it near the garden or compost pile.  Doing so will risk the fungi infecting other plants – either this year or next year.

Keep in mind that it is a “best practice” to use crop rotation to confuse the pests and diseases.  If they don’t see their favorite plants coming back year after year, they will most likely die off or move on.


Wise Words From Jed

My neighbor, Jed, dropped one of his pearls of wisdom on me yesterday.  Jed is a retired farmer who, as he says, has “seen it all.”

He asked me, “Jim – do you know the true definition of marriage?”

Since I knew that I would be wrong no matter what I said, I replied, “No, Jed – what is the true definition of marriage?”

Jed sat back and drawled, “Well, young fella, marriage is a relationship where one person is always right.  And, the other person is the husband!”The boss - who is always right!

Jed sure hit the nail on the head!  Don’t you agree?

Leave a comment or email me – and tell me what you think of growing collard greens – like a true down south country boy!

    Good tips about growing collard greens. I always buy them, but I’ve been wanting to grow them for awhile now. I think this will be the year I’ll do it, and I’ll keep this post in mind when I do. Especially the advice on how to keep pests under control.

      Hi Nate,

      Collard greens are so easy to grow – it’s a wonder more home gardeners don’t stick some in their garden every year.  But, the key is to keep the bad bugs from eating more of the greens than you do.

      Good luck and let me know how your collard greens harvest is!

    I love collard greens. I am from Thailand and growing up eating this collard greens soup with spare ribs, that was my favorite dish that my dad always made for me back in the days. I also love the southern dish with ham and collard greens as well and yes with cornbread, yumm. Comfort food is the best. I’m craving that now after reading your post and some fried catfish (not so healthy but I love it)

    Thank you for the tips on how to plant collard greens. Maybe, I can plant them now around spring? The weather in NY is really crazy, it is still chilly out and we are in mid May, that might be good for the collard greens like you suggested. By the way, Jed sounds like a funny guy, lol have to tell his quote to my husband. I will look into the container garden like you suggested, I have limited space too. Thanks again!

      Hi Nuttanee,

      You’re sure naming off a bunch of my very own comfort foods.  Now, I’m gettin’ hungry!

      Right now is a good time to get started if you want to get a good crop of collard greens – especially, since it’s still a little cool in your area.

      I’ll have to tell Jed that you enjoyed his story.  I’m sure he’ll appreciate it!

    Hi Jim. I am eating lots of vegetables since it’s been about 2 months that i switched to a healthier diet (aiming for vegan but still not there).

    Everyday i eat my salad which is composed of greens, olive oil, tomatoes, carrots, garlic, cucumber, pepper. I don’t grow any collards but my mother occasionally does.

    I think there might be a time in the future where i will need to plant some collard greens and other veggies. I read all the article about cultivating collards and how to handle the process and i will revisit your site in the future where more information will be added.

    Thanks for the interesting article. Keep up the good work

      Hi George,

      Glad you liked my “growing collard greens” article.  If was near and dear to my heart – and, to my stomach – since I am a big fan of Southern cookin’!

      Don’t get too carried away with the vegan lifestyle.  While it’s good to eat as many fresh veggies as you can, it is still a good idea to get the bulk of your protein from meats, chicken, and fish.  Of course, there are many folks who think otherwise – it’s just my humble opinion.

    My mother always had several rows of collard greens in her back yard. Every time I would visit her, I would harvest enough for both families. I like mine with some bacon mixed in. The bacon gives them a flavor that we all liked.

    Can collard greens be grown in pots? I don’t have any ‘ground’ except for a 2 foot strip along our patio. Long time ago, I was able to grow tomatoes there, which produced way more than I could use so gave a lot away to neighbors and other family members.

      Hi Barbara,

      I like a little extra flavor in my collards, too – either bacon or fatback!

      I’ve grown collard greens in containers – mostly 5 gallon buckets. Just make sure the dirt is at least a foot deep – and, that the container has drainage holes in the bottom to avoid the plants getting root rot.

      If you keep the containers outdoors, you can get by with either Jim’s 50/50 soil mixture – or, Miracle-Gro garden soil. Use Miracle-Gro potting mix if the greens are growin’ indoors – and add a couple of grow lights if they’re not close to the window – as a substitute for sunshine.
