Plant collard greens  ¼ to ⅛ inch deep in free soil in early spring after the hazard of the final frost has handed, or in late summer season 6 weeks earlier than the primary frost. Plant one to 2 seeds per 6 to eight inches. Once they’ve grown true leaves, skinny the seedlings to about 18 inches aside. You can simply divide seedlings and plant them elsewhere. The identical goes in a develop bag or container. Seeds will also be planted indoors.

Search your backyard each day in hotter seasons for areas that want further love. Take notice of those necessities and also you’ll have pretty collard greens rising by means of summer season, fall, and winter. 

Sun and Temperature

You’ll discover collard greens rising in USDA hardiness zones 6 by means of 10. They are biennial crops in zones 7-10 and reseed to return again every season. I’ve chopped the stalk down in summer season leaving simply the foundation to search out it sprouting once more in fall.

Collard greens choose full solar to partial shade with at the very least 5 strong hours of direct solar per day. 

It’s finest to develop collards in a cool season, in early spring or late summer season when it’s 55-75 levels Fahrenheit. Although they’re hardy, collard greens are delicate to freezing climate and intense warmth and should be well-established to climate these excessive situations. 

Young collard crops will deplete in excessive warmth, and stunt simply in frosty climate. Mature crops can deal with temperatures as little as 20 levels and as excessive as 95 levels. If your spring is particularly heat, use a shade fabric to shelter collard begins from solar rays. Or in case your fall is remarkably chilly, attempt a frost fabric. 

Water and Humidity

Collards want a variety of water to thrive. Mine are doing nice on this unusually moist cool season we’ve had right here in Texas. Because it rained nearly daily in May, I didn’t must water my collard greens in any respect throughout that month. However, when the summer season warmth reaches triple digits, I’ll have to stay vigilant and water at the very least twice a day to forestall browning and burning of the darkish inexperienced leaves.

Generally, collard greens choose at the very least one to 1 and a half inches of water per week. It’s finest to water greens on the base of the plant to forestall powdery mildew or damping-off on tender leaves. If you’re watering by hand, in cool seasons water nicely as soon as within the morning. In the warmth of summer season, rise earlier than the solar does to water nicely after which water once more because the solar units. 

The finest kind of irrigation for rising collard greens is drip irrigation. This focuses water on the base of the plant close to the roots, stopping any injury to the leaves above. Irrigation within the type of sprinklers or misters isn’t nice for collards because the leaves are liable to illness after they stay moist too lengthy. 


Collard greens like well-draining soil wealthy with natural matter. Soil pH ought to stay impartial, at about 6.5-7.0. Since collard greens are leaf-producing crops, they’ll want nitrogen to thrive. Poor soils are usually not suited to host these greens. Planting collard seeds or begins in ready soil with good drainage is finest. Good drainage retains the fungal and bacterial ailments the leaves are liable to at bay. 


Where you plant collards determines how a lot fertilizing they want. I fertilize my leaves with a full spectrum primary foliar feed weekly. This retains them wholesome and vigorous. I’ll additionally do a month-to-month soil soak with the identical fertilizer, which accommodates compost tea, sea kelp, molasses, and apple cider vinegar. If it’s been raining so much, I wait to use foliar fertilizer to forestall leaf spots and mildews. 

Since nitrogen is important for leaf manufacturing, excessive nitrogen fertilizer or a fertilizer with low phosphorus works nicely. Slow launch, foliar utility, and soil soaks are nice for collards. Apply a excessive nitrogen fertilizer to the bottom of your crops when they’re younger. If you wish to take away a plant, however go away the foundation, unfold compost over the backyard the place the plant was to replenish vitamins to the soil. 


One of the one occasions it’s essential to prune is when your plant bolts prematurely. Remove bolts earlier than they flower to maintain vitamins flowing into leaf manufacturing moderately than flower manufacturing. Simply snip the bolt about one inch above the primary progress level of the leaves with a clear pair of pruning snips.

Search the plant and take away any broken leaves that would have wilt, mildew, or leaf spot as they seem all through the life cycle of the plant. Some counsel collards ought to be staked, however that is determined by the variability. If your crops get tall, add a stake to the aspect to help your fall crop.


If you’re rising tree collards, you possibly can take a chopping to propagate them. Most varieties, nevertheless, solely propagate by seed. This yr, I made a decision to let my collard inexperienced plant develop past harvest time, and let it flower. Once the flowers died, seed pods grew and fattened. I snipped off the pods and positioned them in a paper bag. They popped within the bag, and I separated seeds from the pod detritus. This is one of the best ways to avoid wasting collard seeds. After you harvest collards and collect seeds you possibly can plant collard greens seeds for an additional harvest. 

Harvesting and Storing

Collards are hardy within the backyard, they usually’re hardy in storage too. Here are a couple of methods to reap collards and retailer them to share with household and associates. 


Once leaves attain a 6-8 inch dimension, they’re prepared for harvest. Much like different crops within the cabbage household, merely snap leaves from stems beginning on the base of the plant. Alternatively, you should use a hand device to snip off leaves. You can do that as wanted all through the plant’s total life cycle in mainly any season. You can even harvest your entire plant too. To harvest your entire plant, merely snip it on the base of the soil and canopy the foundation with compost. 


Collards will be canned, blanched and frozen, or saved contemporary within the fridge.

Canned collards will final at the very least a yr with the right seal. Please notice that these should be stress canned as they’re low-acid meals, and water bathtub canning will not be protected for many leafy greens. Those which have been opened ought to be consumed inside 5 days.

Blanched and frozen collards (that are nice in your favourite morning fruit smoothie) may also last as long as one yr within the freezer. Fresh greens final one to 2 weeks if they’re stored between damp paper towels. 

I discover it finest to solely take what I would like from the plant and use it immediately. If you might have many collard crops, canning or freezing could possibly be a wonderful answer to storing them earlier than the flowers cycle concludes.

Growing Problems

Since collards will bolt if it’s too heat, they usually’ll expertise stunted progress in the event that they’re in situations which might be too chilly use frost fabric or shade fabric as wanted.

Collards that don’t have sufficient mild will develop lengthy, spindly leaves that received’t style pretty much as good as these grown in the precise situations.

Without sufficient nitrogen, collard inexperienced leaves received’t develop as shortly and will expertise yellowing. If this continues for too lengthy, leaf collapse can happen. 


These supple greens are a most well-liked vacation spot for pests within the spring and summer season months. This is why it might be higher in some locations to develop collard greens within the fall for meals, after which permit them to change into a entice crop in spring. Search your plant often for indicators of pests and also you’ll be capable of hold collards wholesome and completely happy all year long. 

Aphids and thrips are two insect pests that like to munch on the leaves of your crops. Aphids group up in colonies and feed in your crops for sustenance. They congregate on the underside of leaves and eat small holes by means of them. Thrips aren’t spherical like aphids; moderately, they’re simply as small however lengthy and skinny. They have a tendency to alter the construction of leaves as they feed, contorting them as they go. Control each with a powerful stream of water in much less critical circumstances.

Flea beetles are one other pest that take pleasure in feasting on this vegetable crops’ scrumptious leaves. They are shiny, small black beetles that soar from place to put very similar to a flea. They have a tendency to hold round in the course of the heat rising season. They go away holes in leaves the place they left off and will be managed with soapy water traps. If they infest your greens, attempt a bit of spinosad or pyrethrin foliar pesticide weekly till the problem ceases. 

The root-knot nematode can solely be seen on the root stage however will trigger full vegetable collapse if left unchecked. This pest causes galls on the roots of your collards because it chews on them. If your greens fail and the roots have small galls on them, you’re possible coping with these microscopic pests. While there are industrial nematicides obtainable, the most effective remedy is making use of helpful nematodes to fight the root-knot nematodes.


Most of the fungal and bacterial ailments collard greens expertise come from planting too shut, improper watering, improper planting, or unusually moist situations.

In some seasons, it might be price chopping the stem of your plant on the base if the season has been too moist and downy mildew seems. Making the precise determination on the proper time can save this vegetable. Remember to maintain collards at the very least 18 inches aside. If caught early sufficient that it’s not extreme, take away any leaves with seen mildew and spray the remainder of the plant with a copper fungicide.

White leaf spot and cercospora leaf spot should be aggressively managed early on or they’ll devastate your plant, the greens round it, and probably your neighbor’s greens. Alternaria leaf spot might also trigger damping-off in collard begins in addition to leaf spot. Vigilance is vital right here within the moist spring and fall seasons. Some fungal leaf spots will be managed with copper fungicide sprays, however some can’t be handled in any respect. Severe infections might imply eradicating your entire plant and disposing of it in a plastic bag to be taken to the landfill. Do not compost contaminated supplies from plant ailments.

Brassicas are inclined to clubroot attributable to the pathogen Plasmodiophora brassicae. This illness can initially appear like nematode injury, however the galls are a lot bigger and in time the foundation will utterly rot away. This causes plant demise, and the spores of this fungus-like soil pathogen can linger within the soil for as much as 20 years. Avoid planting brassicas within the affected space for 5-7 years after discovering crops with clubroot. Dispose of all remaining root materials with out composting. Recent analysis signifies {that a} particular micro organism, Bacillus amyloliquefaciens, might assist crops to withstand clubroot injury; this micro organism can typically be present in natural fertilizers with added micro organism and mycorrhizae, so test labels to see if yours accommodates it!
