Cabbage Farming

Conditions for Cabbages Farming in Kenya

Cabbages in Kenya Grow well at altitudes of between 700 and 2,200 metres above sea level, with a base annual rainfall of 500 mm. The ideal growing temperatures are between 16 and 20 degrees celsius. 

The soils for growing cabbages should have a pH range of 6.0 to 6.5 with high organic matter content.  Sandy or loam soils that drain well are recommended for cabbage farming. 

Propagating Cabbages

Selecting the right cabbage seeds

Cabbages are propagated using seeds.  This is done in a nursery in order to give the cabbage seedlings a good start. 

The first process is selecting the seeds. Select cabbage seeds of a variety that is ideal for your ecological region and also that will produce cabbages for your market. Resistance to some pests and diseases is also an attribute you will need to look at when selecting your cabbage seeds. 

Establishing a nursery for your cabbage nursery

The site where you will plant your cabbage seed should not have had a cabbage crop before.  After site selection, you should prepare the cabbage nursery to be one metre wide with any required length. 

Prepare drills that are 10-20cm apart and sow the cabbage seeds, covering them lightly with soil.  Irrigate the seedbed thoroughly after planting. Water frequently, but avoid too much water as this can lead to a disease known as Damping-off. 

Mulch your cabbage seedlings in order to avoid weeds and conserve water. 

Transplanting Cabbage Seedlings

In 30 days after germination, the seedlings will be ready for transplanting. Harden the seedlings 2 weeks before the day for transplanting by reducing the frequency of watering and shade over the nursery. 

The field for planting cabbages should have been prepared and manure applied at the rate of 5 to 8 tonnes per acre. Mix the manure into the soil using your preferred method. This should be done 2 weeks before transplanting, in order to give time for the manure to be incorporated into the soil.  Avoid manure that is not well decomposed, as this might lead to cutworm infestation. 

Prepare rows of either 30 to 60 centimetres apart depending on the variety of cabbage.

Two to three handfuls of manure should be applied on each planting hole and 10 grams (2 teaspoons) of DAP per planting hole.  This amounts to 80kg per acre. Do not apply DAP on acidic soil, but use DSP, TSP or NPK. Make sure the fertilizer is mixed well with the soil to prevent scorching your cabbage seedlings. 

The cabbage plants should be spaced 30 to 60 centimetres apart, depending on the variety. The spacing for cabbage varies from 30 centimetres by 30 centimetres to 60 centimetres by 60 centimetres. This gives a cabbage population of 11,111 to 44,444 cabbages per acre. 

Irrigation for cabbages

Cabbages require 500 millimeters of water. If this is not available, you will need to irrigate your cabbages either using drip, furrow, or overhead irrigation.  This is to increase the cabbage head size, prevent head-splitting, and ensure the heads are formed in a uniform manner. 

Reduce the frequency of watering as the cabbages mature. Make sure there is no waterlogging as this will lead to magnesium and phosphorus deficiency. 

Top Dressing for Cabbages

KALRO recommends that cabbages top-dressed with CAN fertilizer two times after transplanting;

  1. Two to Three weeks after transplanting at the rate of 10 grams per plant. This results in 100 kilograms per acre of CAN fertilizer. 
  2. The second topdressing is done at the rate of 20 grams per plant when the heads begin to form.  This results in 200 kilograms per acre of CAN fertilizer. 
Fertilizer/ManureRate Per acretime
Animal Manure8 tonnes per acre2 weeks before transplanting
DAP/DSP/TSP/NPK (choose one depending on Ph level of soil. Do not apply DAP on acidic soils)10 grams per planting hole2 weeks before transplanting
CAN Fertilizer10 grams per plant2-3 weeks after transplanting
CAN Fertilizer20 grams per plantWhen cabbage heads begin to form

Pests Affecting Cabbages

There are several pests that might attack your cabbage crop, leading to decreased yields. Controlling these pests in cabbages is a major step towards obtaining the desired garbage harvest quantities and quality. 

Diamond Black Moth

The DBM moth is grey in colour. When it closes its wings, a diamond pattern can be seen at the back. 

The diamond black moth lays about 400 eggs under the leaves. As the diamond black moth larvae is developing, it feeds on the leaves leaving holes that resemble windows. This will make your cabbages not develop heads if the infestation happens early.   

The diamond black moth can be controlled by:-

  1. Use of pesticides, either chemical ones or biopesticides
  2. Use of wasps from the Diadegma family, that act as parasites to the Diamond Black Moth. If using wasps, be careful not to use chemical pesticides, as these will harm the wasps.  
  3. Use of neem-based insecticides
  4. Intercropping cabbages with repellent crops e.g tomatoes or trap crops such as Indian Mustard. If intercropping with tomatoes, the tomatoes should be planted 30 days before the cabbages are planted. 

Cabbage Sawfly

The Sawfly, also known as the cabbage leaf sawfly is a wasp that lay eggs inside the leaves of cabbages. It has two pairs of wings, a dark head, and thorax, and a yellow abdomen. The larvae of the sawfly are what cause damage to cabbage. The sawfly larva is grey in color, resembling a caterpillar, and feeds on the leaves of cabbages, leaving only the vein. 

The cabbage sawfly can be controlled by the removal of any wild host plants that belong to the cabbage family, removal of the larvae by hand where feasible, and the use of both organic and chemical pesticides. 


Aphids damage cabbages by sucking sap from the plant, leaving the leaves curled and resulting in the poor formation of cabbage heads. There are three types of aphids that affect cabbages.  These are:-

  1. Green Peach Aphid
  2. Mealy Cabbage Aphid
  3. False Cabbage Aphid. 

Aphids can be controlled by the use of natural enemies e.g ladybirds and wasps.  You can also use pesticides and insecticides to control aphids on your cabbages. 


Slugs hide under the cabbage leaves, eating the leaves.  This affects the quality of cabbages harvested.  The slugs in cabbages can be controlled by drowning them.  Dig in tins in the field. Fill in the tins with water and add yeast to attract the slugs. The slugs will then drown in the water. 


Cutworms affect cabbages by chewing the cabbage stems partially or completely. This will make the cabbage plant fall.  Cutworms are blackish-grey larvae that hide in the soil around cabbages. They will come out at night to eat your cabbage stems, then hide during the day. 

Cutworms in cabbages can be controlled by:-

  • Use of insecticides
  • Exposing them to their enemies by ploughing the soil
  • Removing weeds early enough interferes with the sites where they lay eggs
  • You can look around the soil near the plants and remove the cutworms by hand. 
Diamond Black MothBiopesticides, chemical pesticides, intercropping with crops that repel them, use of parasitic wasps. 
Cabbage SawflyPesticides, destruction of wild host plants, and hand picking where feasible.  
AphidsUse of natural enemies, use of pesticides, and insecticides. 
SlugsUse tins with water and yeast.
CutwormsHand removal, use of insecticides, early weed removal, ploughing. 

Summary of pests affecting cabbages

Diseases affecting cabbages

Club Root

Club roots in cabbages lead to swelling of the roots. They develop galls and the shape of the roots is distorted. It is caused by a fungus. The swollen roots are then infected by bacteria leading to rotting. 

To control club roots in cabbages, practice crop rotation, and destroy infected plants. Apply lime to the soil.  This creates an environment that is not favourable to club root. 

Bacterial Soft Rot

Bacterial soft rot in cabbages is a soil-borne disease that spreads quickly when water splashes from leaf to leaf. After harvest, the cabbage heads soften and then rot, developing a very bad smell. 

To control bacterial soft rot in cabbages, rotate with cereals and legumes. Maintain proper field hygiene and do not harvest when it is wet. Destroy infected plants.  Harvested cabbages should be handled and stored well. You can also use copper-based fungicide when the heads begin to form. 

Alternaria Leaf Spot

Alternaria Leaf Spot in Cabbages is caused by fungi. It is displayed by circular spots on the surface of older leaves, which enlarge into concentric rings with yellow borders. The infected area falls off leaving a hole. 

In harvested cabbages, the spots enlarge and may give way to soft rot bacteria, leading to bacteria soft rot as described above. 

To control Alternaria Leaf Spot, use clean planting material that is free of disease and practice crop rotation. Any infected plants should be destroyed. 

Ring Spot

Ringspot in cabbages spread by wind. It can also be spread by using compost that was made using infected plant remains. It is a seed-borne disease that can come from the use of infected seeds. 

In cabbages, ring spot is shown by brown-grey spots on leaves with a green border and blackish inner zones. 

To control ringspot, use clean seeds. Practice crop rotation, where you should not plant a crop from the same family for at least 2 years. Maintain good field hygiene. You can also use fungicides. 

Black Leg

Blackleg, also known as dry root canker is a seed-borne disease, spread by crop remains, infected seeds, and tools. Infected cabbages will dry suddenly or fall over as the cabbage head becomes heavier. The cabbage leaves will have light brown spots. The spots on the leaves eventually develop grey centers with many black spots.  The cabbage stems develop cankers that move to the roots, killing them. 

To control black leg, use clean seeds that are free from disease.  Practice good field hygiene and crop rotation. The soil should have good drainage. Plants that have black leg should not be used as animal feed, as the manure from the animals will carry the disease. 

Black Rot

Black rot, caused by bacteria is characterized by v-shaped brown lesions on the leaf margins. The veins turn black. A black ring is seen on the stem when cut across. Infected cabbage heads eventually become soft and turn black, They rot and produce a very bad smell. 

Black rot spreads mostly when temperatures are hot and when the environment is wet. 

To control black rot, use clean seeds and destroy plant remains by fire. Rotate your crops for 3 years. You can choose to plant cabbage varieties that are resistant to black rot. The use of copper-based fungicides can help if applied at the beginning stages of the disease. 

Damping Off

As a common disease in cabbages, damping off is a fungal disease that affects cabbages mostly in the nursery. The cabbage seedlings rot at the bottom of the stem, eventually collapsing. It affects cabbage seedlings mostly during the rains as a lot of moisture creates the perfect condition for damping off. 

To control damping-off, do not plant your cabbage seedlings where there has been an infestation of the disease before. Make sure the soil does not have too much moisture. 

Space the cabbage seedlings well so as to allow the soil to dry, in case of excess moisture. Control your watering activities to make sure that the soil does not get too wet. 

The use of crop rotation and clean seeds is highly recommended. Where possible, solarize your soil so as to kill any disease-causing organisms in the soil.  Solarization is the use of clear plastic cover over the seedbeds, in sunny seasons. This causes the soil to heat up, hence killing any disease-causing organism. 

You can also use fungicides to control damping off. 

Club RootCrop rotation, lime application to soil, destruction of infected plants.

Harvesting Cabbages

Your cabbages will be ready for harvesting after two and a half months to 4 months, your cabbages will be ready for harvesting. The time for harvest depends on the variety of cabbage and ecological region. 

You will be able to tell that the cabbage is mature when the head becomes solid. They will feel firm when squeezed.  You have to harvest them at this point, or else they will start splitting. 

The heads should be cut at the base, with the outer leaves that will protect them and keep them fresh during transport and in the market. Injuring the head will lead to rotting. 

With good management practices, your cabbages will yield between 15 tonnes to 70 tonnes per acre, depending on the variety. 

Cabbages are sorted, where the ones with diseases or are damaged are put aside and the rest taken to market. The grading for cabbages is as follows:-

  1. Small – Small cabbages will weigh between one and two kilograms
  2. Medium – Medium cabbages will weigh between three and four kilograms
  3. Large – Large cabbages will weigh over five kilograms. 

In the market, cabbages are sold at different prices, depending on the grade.
