Tomato cultivation in a greenhouse

There are a large number of tomato varieties that can be grown in a greenhouse. However, if you are looking for the most productive ones or the ones that can best take advantage of the conditions of a greenhouse, they are the following:

• Caramba tomato is one of the ones with the highest production in greenhouse. It offers some large tomatoes, it is precocious and very productive.
• Tomato 73 – 36 is another variety that offers a high production, as well as large fruits. However, its foliage is very thick, so the task of harvesting is somewhat difficult.
• The Antilles tomato variety is also a very good option, since its flavor is highly valued and, although it produces smaller fruits, it is of high production and precocity.
• The Cabrales tomato also offers high productivity, although it has a disadvantage that it takes a long time to start producing.

In this other AgroCorrn article we talk about more than 30 types of tomatoes .

Once you have decided on the variety to put in your covered garden, follow these tips for growing tomatoes in the greenhouse :

Temperature for growing tomato in greenhouse

The first thing when growing tomatoes in a covered garden is to control the temperature, which must 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 maintain the tomato crop, it will be necessary to keep the humidity below 90%, in addition to ensuring that the environment is ventilated and with fresh air. Otherwise, you are likely to find mold problems on the leaves of your tomatoes.

Substratum

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.

Irrigation of tomato in greenhouse

It is highly recommended that you have a drip irrigation system in the greenhouse, so that each plant receives its measured and necessary dose of water. If you have hydroponics in mind, it is also a very good option for this plant.

In this other post you will find the instructions on How to make a home drip irrigation system .

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 are between 10 and 15 cm tall, it will be time to transplant them back to their final location.

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

Tomato fertilizer and pollination

Fertilize your tomatoes regularly, removing the suckers every week leaving only the main shoot and a single shoot (the tallest one). This way the plant will grow upwards. In addition, you will need to stalk 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 gardening vibrator. Do the pollination always between 10 in the morning and 2 in the afternoon every other day.

There are many different ways of staining tomatoes. In the greenhouse, one of the most used is the Florida fabric . To support tomatoes with rope with this technique, some structures similar to trellises are formed, which we keep high with stakes, and the ropes are tied, leaving them taut, so that the tomato plant grows by leaning on them.

It is also common to use the simple method of a stake for each tomato plant , which we will carefully tie to it as it grows, or to use tripods on which several plants can lean and which also protects them from the wind. Finally, wire cages and fences are also widely used to make trellises in the greenhouse, especially the former, since they do not require any type of mooring of the plant.

Now that you know the indications for growing tomatoes in a greenhouse to achieve a good production for self-consumption, we advise you to deepen your knowledge to take care of tomato plants and obtain good fruits. For this, we recommend these Green Ecology guides on How to grow organic tomatoes and How to fight tomato pests ecologically .
