When Can You Put Tomato Plants in a Greenhouse?

Tomato plants are among the most popular plants to grow in a greenhouse. Not only can they produce a bountiful harvest, but they also thrive in the controlled environment of a greenhouse. However, one of the most common questions that greenhouse growers ask is when they can put their tomato plants in the greenhouse. The answer, of course, depends on a few factors.

Temperature

One of the most important factors to consider when deciding when to put tomato plants in a greenhouse is the temperature. Tomato plants are warm-season plants that require a consistently warm temperature to grow and produce fruit. Therefore, it is important to ensure that the temperature inside the greenhouse is warm enough for the plants to thrive.

The ideal temperature for tomato plants is between 65 and 80 degrees Fahrenheit during the day and between 60 and 65 degrees Fahrenheit at night. If the greenhouse temperature falls below this range, the plants may not grow properly, and the fruit may not develop as it should.

Lights and Moisture

Another important factor to consider is the amount of light and moisture the tomato plants will receive. In general, tomato plants need at least 8 hours of sunlight per day to grow properly. If the greenhouse does not receive enough natural light, artificial lighting may be necessary.

In addition to light, tomato plants also require a consistent level of moisture to grow properly. The greenhouse should be equipped with an irrigation system that can deliver water to the plants on a regular basis.

Transplanting Seedlings

If you are starting your tomato plants from seeds, you will need to transplant them to the greenhouse once they have sprouted and have developed their first set of true leaves. This usually occurs about 4 to 6 weeks after the seeds are planted.

Before transplanting the seedlings to the greenhouse, it is important to harden them off by gradually exposing them to outdoor conditions. This will help prevent shock and ensure that the plants adapt to their new environment more easily.

Conclusion

Putting tomato plants in a greenhouse requires careful consideration of the temperature, lighting, and moisture levels. In general, tomato plants should be put in the greenhouse once the temperature is consistently warm enough for them to grow and produce fruit. Whether you are starting your plants from seeds or transplanting seedlings, it is important to follow the proper procedures to ensure that your plants thrive in the controlled environment of the greenhouse.
