Are you planning to plant and grow tomatoes in a greenhouse in your garden all year round? However, you are not sure that you have all the knowledge necessary for this practice or perhaps you need to be reassured about the correct procedure to apply? No matter, we are here to help you and remind you of the essential principles for growing tomatoes in a greenhouse. Discover without further delay the tips and advice that every gardener must have for a production that meets their expectations.
Recommended Spacing for Greenhouse Tomatoes
A forewarned grower is worth two and planting tomatoes in a greenhouse should not be left to chance if you want to obtain an excellent harvest and give the seeds and seedlings a better chance of growing in good conditions. In this respect, the spacing between tomato plants in a greenhouse is of capital importance. It is the genesis of any crop which, moreover, determines the success of this production of fruits that are so tasty and appreciated by a majority of consumers. Thus, to successfully sow your seeds, you must respect a pre established distance between your tomato plants. It is important to remember that this distance also depends on the type of tomato you want to produce in your greenhouse.
For example, it is recommended:
For cherry tomatoes: allow for a spacing of 70 centimeters between plants.
For other varieties: planting holes should be spaced respecting a distance of 50 centimeters between plants.
You should know that whatever tomatoes you want to grow in a greenhouse, they need a fairly large space between each seedling, because tomatoes are a plant whose cultivation is delicate. Indeed, the fruit takes up space and needs space to develop and give pretty and delicious tomatoes. Moreover, if the distance between seedlings is not respected, it is possible that fungal diseases will develop and undermine your production and the strength of your work.
Factors to Consider When Growing Tomatoes in a Greenhouse
Growing tomatoes in a greenhouse requires consideration of factors other than the spacing between each plant in order to promote fruit growth and plant production. Many parameters must therefore be considered:
Temperature
The advantage of the greenhouse compared to outdoor tomato production is based on the protection that is provided to the plants at all stages of their growth. In fact, it is necessary for tomatoes to develop that they benefit from constant heat , protection against climatic hazards and natural light. Through the greenhouse, tomatoes find what they need, provided that at the time of planting, you are careful to choose a location that does not expose the plants to too much sun exposure or a lack of sunlight. The ideal temperature that must prevail in the tomato greenhouse for a healthy crop should be between 20 and 30 degrees during the day and between 15 and 20 degrees at night.
Soil Composition
To obtain beautiful tomatoes in a greenhouse, it is essential to pay attention to the quality and composition of the soil. The soil is, in fact, a prime asset for the proper development of seedlings and seeds. A varied soil rich in organic matter is recommended to be fertile. Also, do not skimp on the means and plan to buy or compose yourself fertilizers and substrates that will nourish the soil for a productive soil. Favor natural and organic nutrients such as horse manure that you place under the tomato plants before covering it with soil. The plant will draw the nutrients essential to its growth.
The Quality of Watering
In addition to the need for quality soil and a suitable temperature, growing tomatoes requires a large amount of water. Tomatoes are known for being very water intensive (water accounts for 94% of their composition). Therefore, as soon as the flowers appear and the first fruits appear, it is essential to water the plants constantly. It is also important not to water the leaves in order to avoid the risk of disease. For quality watering, water can be distilled using a drip system which also allows you to control watering.
Other tips for planting tomatoes in a greenhouse
Knowing the spacing needed for planting tomatoes that are grown in a greenhouse does not exempt you from taking into account other parameters that promote production. Among the elements to consider, you must take into account:
From the planting date: in a greenhouse, this is brought forward compared to planting outdoors (which is done in spring in April). The month of February is therefore an opportune time to plant the seeds.
Starter watering: for the seeds to grow well, it is important that a sufficient amount of water is provided at the beginning. The standard is that 3 liters per m² should be administered to the plants.
Plant orientation: to obtain beautiful tomatoes, it is recommended to orient the flowers towards the inside of the greenhouse.
Fertilization at the time of planting: fertile soil is one of the guarantees of good plant development. However, for production to be optimized, it is vital that the supply of substrate and nutrients is carried out every two weeks.
The planting distance of tomatoes in a greenhouse is one of the assets of successful fruit production. However, it is not the only element to consider. Growing tomatoes requires constant attention to ensure that the plant does not suffer from diseases, that the tomato is not exposed to pests or that it does not lack water. By following the advice of Crop Mogul, we have no doubt that your production of tomatoes in a greenhouse will be there.
