Introduction

Tomatoes are one of the most popular plants grown in greenhouses. They are relatively easy to grow, yield a lot of fruit, and can be grown almost all year round in a greenhouse. However, tomato plants need specific conditions to thrive, and knowing when to put them in an unheated greenhouse is crucial to ensure a healthy crop. In this article, we’ll discuss when to put tomato plants in an unheated greenhouse.

The right conditions for tomato plants

Tomatoes need plenty of sunlight, warmth, and moisture to grow properly. When grown in a greenhouse, they also need good air circulation to prevent disease and pests. Before putting tomato plants in an unheated greenhouse, make sure the temperature outside is consistently above 50°F (10°C). This is because tomato plants prefer temperatures between 60°F (15°C) and 85°F (30°C) to grow well.

The right time to plant tomato seedlings in an unheated greenhouse

The right time to plant tomato seedlings in an unheated greenhouse depends on your location and climate. In general, you should plant tomato seedlings when there is no longer a risk of frost. This can range from early spring to late spring, depending on where you live. You can also use a soil thermometer to ensure the soil temperature is at least 60°F (15°C) before planting your seedlings.

The right way to plant tomato seedlings

When planting tomato seedlings in an unheated greenhouse, start by choosing a well-draining soil mix. Add some organic matter to your soil to help retain moisture and nutrients. Plant your seedlings in a hole that is about twice the size of the seedling’s root ball. Water the seedlings thoroughly, and place a stake or cage next to each one to help support the growing plant.

The right way to care for tomato plants in an unheated greenhouse

Once your tomato plants are established in your unheated greenhouse, they will need regular care to thrive. This includes watering the plants regularly, ensuring good air circulation, and fertilizing them every few weeks. You should also check your plants for pests and disease regularly, and take action immediately if you notice any problems.

Conclusion

Tomatoes are a popular crop for greenhouse growers, but putting them in an unheated greenhouse too early can lead to stunted growth and poor fruit production. Wait until the temperature outside is consistently above 50°F (10°C), and use a soil thermometer to ensure the soil temperature is at least 60°F (15°C) before planting your seedlings. Once your tomato plants are established, provide them with regular care, and they should provide you with a bountiful harvest of juicy, delicious fruit.
