When Can I Put Tomato Plants in an Unheated Greenhouse?

If you're an enthusiastic gardener, then you're probably all set to start growing some delicious and healthy tomatoes in your greenhouse. However, you may be wondering when is the right time to put your tomato plants inside an unheated greenhouse. In this article, we'll give you all the information you need to know about the best time to put tomatoes in an unheated greenhouse.

The Right Time to Put Tomato Plants in an Unheated Greenhouse

If you want your tomato plants to grow in an unheated greenhouse, then it's essential to ensure that the temperature is conducive to their growth. A tomato plant requires warm conditions to germinate and thrive; otherwise, the plant may die or become stunted. The ideal temperature for a tomato plant's growth is between 65 to 80 degrees Fahrenheit. If the temperature outside is cold, then you need to wait until the temperature inside the greenhouse is warmer before planting tomatoes.

Factors to Consider

Several factors determine whether your tomato plants will grow well in an unheated greenhouse. It's essential to consider these factors before putting your plants in the greenhouse to ensure their growth and longevity. Some of the factors include:

Temperature: As covered above, the ideal temperature range for tomato plants' growth is between 65 to 80 degrees Fahrenheit. You should wait until the temperature inside the greenhouse falls within this range before planting the tomatoes.

Light: Tomato plants require at least six hours of direct sunlight per day to grow and bear fruits. Ensure that your greenhouse is located in a sunny spot that receives enough sunlight to support plant growth.

Climate: The quality of the climate inside the greenhouse plays a significant role in the success of tomato plants. Ensure that you provide adequate ventilation to regulate humidity levels, which should be around 60% to 70%, and prevent the occurrence of diseases.

Preparation Before Planting

Before planting your tomato plants in the unheated greenhouse, you need to prepare the soil to optimize their growth. Some of the preparations include:

Soil fertility: Tomato plants require a well-draining and fertile soil mix. You can prepare the soil by mixing compost and sand in a ratio of 1:1.

Mulching: Use mulch to regulate soil temperature and prevent weed growth, which are detrimental to plant growth.

Watering: Ensure that you water your tomato plants adequately to prevent soil dryness, which could lead to plant damage.

Conclusion

Tomatoes are an excellent addition to any garden, and an unheated greenhouse allows them to grow outside the usual growing season. However, it's essential to ensure that the temperature, light, and climate within the greenhouse are optimal for plant growth before planting. Proper preparation and care will ensure that your tomato plants produce a bountiful harvest.
