When Can You Plant Tomatoes Outside in PA?

Tomatoes are one of the most popular garden vegetables in Pennsylvania, and for good reason. They are easy to grow, have a high yield, and can be used in a variety of dishes. If you are planning on growing tomatoes this year, you might be wondering when the best time to plant them outside is. In this article, we will explore when you can plant tomatoes outside in PA.

Frost Dates in Pennsylvania

The first thing you need to consider when planting tomatoes outside is the average frost dates in your area. Frost can damage or kill young plants, so it is important to make sure that you are planting after the last frost date. In Pennsylvania, the average last frost date ranges from mid-April to mid-May, depending on your location. The first frost date of the season can range from late September to early November.

Choosing the Right Tomato Varieties

Another factor to consider when planting tomatoes outside is choosing the right variety. Some tomato varieties are better suited for cooler temperatures, while others thrive in warm weather. If you are planting early in the season, consider choosing a cold-tolerant variety like 'Early Girl' or 'Celebrity.' If you are planting later in the season, choose a heat-tolerant variety like 'Roma' or 'San Marzano.'

Preparing Your Soil

Before planting your tomato seedlings, you need to prepare your soil. Tomatoes require well-draining soil that is rich in organic matter. Start by removing any weeds and loosening the soil. Add compost or well-rotted manure to improve soil fertility. If your soil is heavy or compacted, you may need to add sand or perlite to improve drainage.

Planting Your Tomatoes

Once your soil is ready, it's time to plant your tomatoes. Start by digging a hole that is slightly deeper than the root ball of your tomato seedling. Gently remove the seedling from its container and place it in the hole. Backfill the hole with soil and lightly tamp down the soil around the plant. Water the plant well to help it settle in and establish roots.

Caring for Your Tomatoes

Tomatoes require consistent care throughout the growing season. Make sure that your plants receive at least an inch of water per week, either from rainfall or irrigation. Fertilize your plants every few weeks with a balanced fertilizer. As your plants grow, you may need to stake them to provide support. Remove any suckers, or side shoots, to encourage your plants to put their energy into producing fruit.

Harvesting Your Tomatoes

Tomatoes are typically ready to harvest 60-80 days after planting, depending on the variety. The fruit should be firm and fully colored. If you are harvesting green tomatoes, they will ripen if you store them in a warm, dark place for a few days. Enjoy your fresh tomatoes in salads, sauces, or eaten straight off the vine!

Conclusion

Planting tomatoes outside in PA can be a rewarding experience. By choosing the right varieties, preparing your soil, and providing consistent care, you can enjoy a bountiful harvest of delicious, home-grown tomatoes. Keep in mind the average frost dates in your area, and don't be afraid to experiment with different varieties to find the ones that grow best in your garden. Happy planting!
