When to Put Tomato Plants in Greenhouse

Tomato plants are one of the most popular vegetables grown in greenhouses. To get the most out of your tomato plants, it is important to know when to plant them in the greenhouse to ensure a healthy and bountiful harvest.

Choosing the Right Time

The ideal time to put tomato plants in the greenhouse is when the soil temperature reaches at least 55°F (13°C) and the outside temperature is consistently above freezing. For most regions, this means planting in mid-to-late spring, usually around May.

It’s important to make sure that the soil is warm enough before planting your tomatoes, since planting them in soil that is too cold can stunt their growth and increase the risk of disease. Use a soil thermometer to check the soil temperature before planting.

Preparing the Soil

Before planting your tomato plants, it’s important to prepare the soil properly. The soil in your greenhouse should be rich in nutrients and have good drainage to ensure healthy tomato plants.

Start by removing any rocks or other debris from the soil. Then, add in some compost or well-rotted manure to help provide the tomato plants with the nutrients they need. Finally, make sure the soil is level and smooth, so that it is easy to plant the tomato seedlings.

Planting the Tomatoes

When it comes to planting your tomato seedlings, there are a few important things to keep in mind. Make sure you water the seedlings well before planting, and plant them at least two feet apart to allow for good airflow and to prevent overcrowding.

After planting, water your tomato plants well to help them settle into their new home. You should also stake or cage the plants to provide support as they grow.

Tending to Your Tomato Plants

Once your tomato plants are in the greenhouse, it’s important to tend to them properly to ensure they grow healthy and strong. This means regular watering, fertilizing, and pruning.

Water your tomato plants deeply once or twice a week, depending on the weather and how quickly the soil dries out. You can also fertilize your tomato plants every two weeks with a balanced fertilizer to keep them growing strong.

Finally, make sure to prune your tomato plants regularly to keep them from getting too bushy and to help maximize their fruit production. Remove any suckers that form in the crotch between the main stem and the side branches, and trim back any leaves that are touching the soil to reduce the risk of disease.

Conclusion

Knowing when to plant your tomato plants in the greenhouse is key to a successful harvest. By waiting until the soil and outside temperatures are warm enough, preparing the soil properly, and tending to your tomato plants regularly, you can enjoy a bountiful crop of delicious tomatoes all season long.
