Wooden Greenhouses In Kenya

Wooden greenhouses in Kenya preceded the now common metallic greenhouses in the country. They are cheaper to build but have a lower lifespan than metallic ones. Popular crops grown in wooden greenhouses in Kenya are;

  • ornamentals such as roses(most common), carnations, chrysanthemums
  • herbs and spices, which are rosemary, mint, geraniums, lemon grass
  • vegetables like indeterminate tomato (most common), cucumber, capsicums, chilies
  • fruits such as strawberry
  • cereals, in this case barley as animal feed

Greenhouse structures are also for production of seedlings, and rooting of stem cuttings. Here, improvements like misters, or foggers to raise humidity are present

How To Construct Timber Greenhouses

i. Know the crop type to plant. This will guide on the greenhouse design and amount of material to use. For instance, a tomato greenhouse will take more material than one with herbs. This is because tomato will require training, and herbs won’t. It also guides on the greenhouse paper to cover with. You will have more light for fruiting crops like tomato, capsicum, chilli, cucumber, and strawberry, or bi/ multicolored flowers. Have a clear polythene for these. Mono-color flowers will have the yellow polythene cover

ii. Determine the plant population you need. This informs the area of the greenhouse

iii. Once you determine the amount of timber required based on the greenhouse area, treat it. This is to prevent weevils and termites from attacking the timber which reduces it’s lifespan. Do not apply motor oil on the timber as treatment. This is because it will contaminate food crops in the greenhouse

iv. Your construction design is the vented type

v. Cover the roof and side ventilations with an insect net. Select the high density gauge which is effective in keeping away white-flies

vi. Make the beds according to the crop type. Beds are important in managing drainage. For seedling production, set up the tables 1M high

vii. Set up the drip irrigation system on the beds. For seedling production, set up he misting or fogging system above. The misters or foggers are 1M apart
