When Can I Leave Tomato Plants Outside?

Tomatoes are a staple in many gardens and for good reason. They’re delicious, nutritious, and fairly easy to grow. However, planting tomato starts too early can lead to disaster. So, when can you safely leave your tomato plants outside?

Wait for Consistently Warm Temperatures

The key to successfully planting tomato starts is to wait for consistently warm temperatures. In general, tomato plants can be put outside when temperatures are consistently above 50°F (10°C) both day and night. However, there are a few factors to consider before moving your plants outside.

Consider the Size of Your Tomato Plants

It’s important to consider the size of your tomato plants before moving them outside. Young tomato plants are more susceptible to damage from the wind and other outdoor elements. Once your plants have grown to be about 8-10 inches tall and have several sets of leaves, they should be sturdy enough to withstand outdoor conditions.

Check the Frost Dates in Your Area

Another important factor to consider is the frost dates in your area. Even if daytime temperatures are warm, it’s possible for there to be frost overnight. This can be detrimental to the health of your tomato plants. Before moving your plants outside, check the average last frost date in your area. Typically, it’s safe to plant tomatoes outside two weeks after your last frost date.

Protect Your Tomatoes from Wind and Sunburn

Even after you’ve moved your tomato plants outside, it’s important to protect them from harsh elements. Wind can be especially damaging to young plants, causing them to snap or break. Similarly, the sun can cause sunburn on the delicate leaves of your tomato plants. Provide shading or cover for your plants, especially during the hottest parts of the day.

In Conclusion

Tomatoes are a great addition to any garden, but it’s important to be patient when planting them. Wait for consistently warm temperatures and make sure your plants are strong enough to withstand outdoor conditions. Check the last frost date in your area and provide protection from wind and sunburn. With a little patience and care, you’ll be harvesting delicious tomatoes all summer long.
