In our greenhouses the nursery is where the seeds are sown before transplanting or a stage of the plant before transplanting, always plant more seeds than the actual number needed to take care of germination percentage and gaping.
The nursery should be well tilted so that the seedlings have easy time germinating. Insecticide and fungicide should be sprayed to control dumping off and insect cutting the seedlings. Watering and mulching should be done to help the plant grow. We have different media used in nursery and tray holders. Media can be soil, coco peat, peat moss among others.

Bed preparation is the digging of soil and preparing where the transplant will stay till harvesting, this is done by preparing furrows at an interval of 70 cm to 30 cm on walking paths in between the beds, incorporation of organic manure or compost should be done at this stage. holes or transplants are prepared at interval and addition of fertilizer is done per hole.
Soil sterilization and potting
When the soil test has been done and found to be containing the tomato wilt pathogen, then soil treatment is essential. Treatment is done by mixing the soil with the manure and then sterilized through burning, fumigation, and steaming of the soil.
Transplanting of the vegetables like tomatoes always take place after 3 weeks from the nursery.
During transplanting, the nursery should be watered thoroughly to minimize plant root injury.
Transplanting of the tomato plants should be done at a spacing of inter-rows of 40 cm and into rows of 30-40 cm. Insecticide and fungicide should be applied to avoid loss of the seedlings. Watering to be done the first three weeks 3 times. 1/2 a liter per plant then twice later for 1/4 liter per plant twice a day. Transplanting results are great when done in the evening.
Top dressing is the adding of slow release fertilizer in small quantities at intervals to supplement the plant food. this is done 15 cm away from the plant 2 weeks after transplanting, repeating 2 weeks later, then once per month until harvesting where the rate might increase depending on the variety. After topdressing applies a good amount of water, to help the fertilizer dissolve in the soil.
Suckering is the removal of suckers from the tomato plant. sucker are growth found between plant main stem and the leaves. the removal is important to maintain one stem that promotes ease of management. Suckers also use a lot of tomato food hence poor fruiting. proper del suckering promote healthy fruit sets and also aeration for the tomato plants.
stalking is the support of tomato plants so that they don't fall on the ground. In the greenhouse, this is done using manila twines which limit fungal infection and are tied to the support system within the greenhouse. The twines are rolled on the tomato stem. this promotes ease in defoliation, de-suckering, and spraying.
Pruning/defoliation is the removal of extra leaves from the plant, this is done from the bottom of the plant to the top during different stages of growth. a determining factor in defoliation is the fruit set/ trusses.
Spraying should be done as soon have there is a disease break, or when scouting has been done and insects discovered, at greenhouse Kenya we give you a spray guide of the greenhouse and outdoor production
Harvesting of the tomatoes should be done twice a week in the greenhouse or once when the tomato has reached a breaker ten weeks from the transplanting day. The harvesting of greenhouse tomato is a continuous process that takes up to eight months of harvesting with proper management and good greenhouse variety selection.
