Land Preparation for growing Sukuma Wiki

When preparing the land for growing Sukuma Wiki, make sure the ploughing is deep, allowing for faster and better root development. Remove any perennial weeds before planting. Prepare the land early enough so as to expose the soil to pests to sunlight and birds.  The birds will eat the pests. Sunlight will kill some of the pests. 

Nursery preparation for Sukuma Wiki

You can sow Sukuma Wiki seeds on open nursery or seedling trays. 

When sowing Sukuma Wiki seeds in open field nursery, establish the nursery where the plants from the same vegetable family have not been planted for 2 years. 

Make the nursery about 1 metre wide.  This will allow you to take care of the seedlings without having to step onto the nursery. The length of the nursery can be as long as desired. If you are sowing in an area with heavy rainfall or heavy soils, it is recommended that you raise the nursery bed in order to prevent waterlogging. 

Mix well-decomposed manure and DAP fertilizer with the soil in the nursery. Phosphorus helps in good root development while the manure improves soil structure and moisture retention.  

In the nursery, prepare drills across the beds at a spacing of 10 to 15 centimetres apart and 2 centimeters deep. Sow the seeds thinly and cover lightly with soil. Cover the bed with a thin layer of mulch, to avoid unearthing of the seeds.  The mulch can be removed after germination. If growing in hot areas, make a shed of 1 metre high. 

Once the seeds germinate, thin the seedlings to 2 to 3 centimeters apart to avoid competition for nutrients and space. Such competition will lead to weak seedlings. Crowding also creates a good environment for diseases. 

Topdressing with CAN, only of poor soils, should be done 2 weeks after germination. 

Water once or twice daily. Control pests in the nursery to ensure the seedlings are healthy.
