Sowing seeds on a nursery bed

  • The seeds are then spread along the fallows in the process called drilling.

Cover the seeds with a thin layer of fine soil. 

  • Apply dry plant materials to mulch the nursery bed and water it on top of the mulch.

Care for the vegetable seedlings in the nursery

  • Vegetable seedlings are taken care of by constructing a shade on top of them to prevent being weakened by direct sunlight and to preserve water, by preventing water lose from the nursery bed through evaporation. 
  • The seedlings should be watered regularly and weed removed from their midst. When the seedlings are ready, you should transplant them into a seedbed.

Preparing a seedbed for planting vegetable seedlings.

  • Transplanting seedlings in the seedbed should be taken care of. This is through weeding, watering and application of fertilizer or manure. Dried up seedlings after transplanting should be replaced in the process called gapping. 
  • Other practices such as mulching, shading application of pesticides to control pests and diseases are important. Pruning of some vegetables such as tomatoes is needed. This is cutting of excess branches.
  • Tall tomatoes varieties need to be trained, so that they grow upright. Once the crops are ready, they need to be harvested in time.

  • However, other vegetable fruits such as sweet pepper may still be harvested when they are green in colour.
  • The ripe fruits are picked by the hand. Care is taken so as not to damage the skin of the fruit. Harvesting of the fruit should be done at the right time to avoid over ripening which lowers their quality.
  • For leafy vegetables such as kale and spinach, it is good to harvest when the leaves are tender and green. The lower outer leaves are broken from the stem to allow the plant to produce more.
  • The cabbage head is removed by cutting the base of the stalk with a sharp panga.

3.3 Innovative Gardening

3.3.1 Vertical and Horizontal Gardening

Vertical gardening is crowing crops above the ground. This is used to minimize the space for practicing crop production. It can be used in places where is enough land to practice gardening on a large piece of land. This practice also save water. 

The importance of vertical gardening is that it is easy to control weeds, pest and diseases. Crops produced from vertical gardens are also clean because they don’t get into contact with soil.

 Leafy vegetables such as kales and spinach are harvested when they large enough to use for cooking. They are carefully plucked using hands to avoid uprooting the whole plant. 

Fruit vegetables are plucked when they are ripe. Tomatoes should be carefully picked when they are ripe.
