What Temperature should You Bring Tomato Plants inside?

If you're growing tomato plants in a garden, balcony or window box, you need to know when it's time to bring them inside before the first frost. So, what's the right temperature for bringing these plants inside?

The Ideal Temperature for Tomato Plants

Tomato plants are extremely sensitive to temperature changes. They require very specific temperatures to grow and thrive. Typically, the ideal temperature for growing tomato plants is between 70°F and 75°F. With that said, tomato plants can tolerate temperatures as low as 50°F once they are established.

When it comes to bringing tomato plants inside, you should make an effort to keep the temperature in their new environment as close to their outdoor temperature as possible. This is especially important if your plants are delicate and tender.

When to Bring Tomato Plants Inside

Before you can bring your tomato plants inside, you need to know when the first frost will occur in your area. The first frost is the date when the temperature is expected to drop below freezing. You can check local weather reports or ask an experienced gardener in your area for help.

Once you have the date of the first frost, you can count back about two weeks to determine when you should bring your plants inside. This will give your plants enough time to adapt to their new environment before the frost arrives. Typically, tomato plants should be brought inside when the temperature drops to 50°F.

How to Prepare Your Tomato Plants for Inside Growth

Before bringing your tomato plants inside, you need to do some preparation. First, inspect the plants for any pests or diseases. If you find any issues, treat them before bringing the plants inside to prevent them from spreading to your indoor plants.

Next, prune the tomato plants back to about 12 inches in height. This will make them easier to transport and reduce the strain on the roots once they are inside. Finally, transplant the plants into clean, sterile pots with fresh soil. This will help prevent any soil-borne diseases from infecting your indoor plants.

Conclusion

Bringing tomato plants inside before the first frost is important to ensure their survival and continued growth. Remember to keep the temperature as close to their outdoor temperature as possible, know when to bring them inside, and prepare your plants for indoor growth. With the right care, your tomato plants can thrive both indoors and out!
