The first thing when growing tomatoes in a covered garden is to control the temperature, which should be kept between 21ºC and 27ºC during the day, and between 16ºC and 18ºC at night. In addition to maintaining these temperatures in your greenhouse during all the months that you are going to grow tomatoes, you will need to keep the humidity below 90%, in addition to ensuring that the environment is ventilated and with fresh air. If you do not do this, it is likely that you will find yourself with mold problems on the leaves of your tomatoes.


For the substrate or soil, it is necessary that the mixture you use has good drainage. If you make your own mix, don’t use unsterilized garden soil.

Tomato irrigation in the greenhouse

Germinate greenhouse tomatoes

Ideally, you should germinate the seeds in a seedbed before taking them to the greenhouse, keeping them controlled and in adequate light and irrigation conditions. Two weeks after they have germinated you can transplant the seedlings into small pots and take them to the greenhouse. Once they measure between 10 and 15 cm in height, it will be time to transplant them back to their final location.

Before this definitive transplant, check that the pH of the soil is between values ​​of 5.8 and 6.8. In addition, it is advisable to add calcium sulfate to the soil, which will help prevent necrosis in the crop.

Fertilizer and tomato pollination

Fertilize your tomatoes regularly, removing the suckers every week leaving only the main shoot and a single (tallest) shoot. So the plant will grow upwards. In addition, you will need to stake your tomatoes, and unless you have your own bees or a large number of them nearby, you will need to pollinate the flowers yourself. For this, you can help yourself with a specific electric vibrator for gardening. Always do the pollination between 10 in the morning and 2 in the afternoon every two days.
