There are three varieties of cabbages in Kenya, to be specific smooth-leafed green, smooth-leafed red, and crinkled-leafed green, otherwise called savoy cabbage.
Cabbage develops well in full sun, however being a cool-climate vegetable, it can endure some shade amid the day. It particularly prefers cool evenings with morning dew. In good highland areas, cabbage can be grown throughout the entire year by progressive sowing after like clockwork.
You can likewise plan your planting cycle in a way that uses the cooler months for growing. Additionally, abstain from planting that will see the harvest develop in sweltering, dry January climate.
You can sow cabbage straightforwardly in Kenya or develop seedlings in a different seedbed and after that transplant.
Cabbage seeds take 4 to 10 days to sprout and if developed in a seedbed, they ought to be transplanted after five to seven weeks. They, from that point, take 80 days to develop and harvest.
In this way, for a July or August reap, you should plant your seedlings in March or April. Be that as it may, you can likewise plant them on any four-month cycle as long as you abstain from sowing in October or November in the event that you are in a more hotter region.
The prescribed spacing is 50 by 50cm to 70 by 70cm for bigger varieties. In a square-foot planting framework, plant a single cabbage for every square foot.
Cabbage is what we call a “substantial feeder”. Cabbage needs satisfactory nutrition to grow those substantial heads.
In this manner, it is ideally grown in soils with some clay content, yet the soil likewise should be profound and rich in natural organic matter with a high water maintenance capacity. This is the capacity of the soil to hold rain or irrigation water for longer periods.
To accomplish this, loosen the soil deeply before planting and dig in 12 to 20 tons of superb manure per acre of land a month and a half before planting.
Cabbage additionally needs very much circulated air through soil, so loosen the soil consistently and apply mulch. A thick mulch layer of 15 to 20cm deep will keep the soil moist and cool. Before head development, load up the soil around the root or stem area. This will increase root and plant growth.
We firmly recommend that you have your soil tested before you plant. A soil test will give all of you the fundamental information you require for effective and feasible fertility management.
Cabbage needs a pH of 6 to 7. In the event that the pH of your field is lower, the recommendation that accompanies the soil test will inform you on the sum with respect to lime you have to fuse preceding planting. Lime ought to be applied three to a half year before planting. So, do your soil tests early and frequently.
The soil test will likewise give you a proposal on the kind and measure of manure you ought to apply.
By and large, cabbage needs the folowing supplement necessities: 93kg nitrogen, 20kg phosphorus and 20kg potassium. In the event that you don’t recognize what the richness status of your soil really is, feeding these measures of fertiliser may make or intensify supplement awkward nature in your soil.
That is the reason soil testing is critical to fruitful fertiliser application and, in this way, farming.
It is significant that sufficient fertilizer excrement application will offer 36kg of nitrogen, in addition to the supplements from phosphorus and potassium.
Fertilizer applications ought to be split into two; at planting and top dressing or even into three at regular intervals. Use of hand crafted fertiliser produced using comfrey leaves at transplanting and when the heads start to shape will give the yield an additional lift.
Cabbage has high water needs, which crest after they begin shaping heads. Consequently, the product is best grown under water system to guarantee relentless water supply.
On the off chance that the soil dries out and after that a high measure of water is given all of a sudden, the heads tend to crack.

Harvesting should be done during cool morning hours to avoid from cracking of the heads.
Check for caterpillars and aphids frequently and dust your cabbages with wood ash from the beginning to keep away from the pests.
Cold season planting limits caterpillar pervasion. Likewise, keep the soil moist or mulched to maintain a strategic distance from flee beetle harm. Aphid invasion is an indication of warmth or water pressure and lacking supplement supply.
Typical cabbage diseases are black leg, black rot or leaf blight, club root, damping off and stem rot. If your cabbages have had problems in the past, look for disease-resistant cultivars.
To avoid soil-borne diseases, don’t plant cabbage-family plants (Brussels sprouts, kale, cauliflower and broccoli) in the same area more than once every three years. Plant cabbage after beans and follow with maize and or potatoes.
Ultimately, for better growth, don’t plant cabbage close to capsicum, chilli, eggplant, garlic, lettuce, maize, mustard, radish or strawberries.
