When to Plant High Tunnel Tomatoes

High tunnels are a great way to extend the growing season for tomatoes, but planting at the wrong time can result in poor yields or even plant loss. Here's what you need to know about when to plant high tunnel tomatoes:

Factors to Consider

The first factor to consider when determining when to plant high tunnel tomatoes is your specific location. Depending on where you live, the ideal planting time can vary by weeks or even months.

Other factors to consider include the tomato variety you are planting, the type of soil and amendments used, and how well your high tunnel is insulated and ventilated.

Early Planting

If you are looking to plant early, a good rule of thumb is to wait until the soil temperature has reached at least 60 degrees Fahrenheit. This will ensure that the seeds germinate and the plants can grow properly.

In some areas, it may be possible to begin planting as early as January or February, but it's important to closely monitor the temperature and provide extra protection for the plants in case of a cold snap.

Late Planting

If you are planting later in the season, you'll want to make sure that the tomatoes have enough time to mature and ripen before the cold weather sets in. Generally, it's best to aim for a harvest date of 3-4 weeks before the first expected frost.

In some areas, it may be possible to continue planting as late as September or October, but again, it's important to monitor the temperature and make sure that the plants have enough time to mature before the cold weather arrives.

Choosing the Best Variety

When planting high tunnel tomatoes, it's important to choose a variety that is well-suited for your growing conditions and planting schedule.

Some popular varieties for high tunnel growing include Early Girl, Celebrity, and San Marzano. These varieties are known for their early ripening times, disease resistance, and high yields.

Preparing the Soil

Before planting your high tunnel tomatoes, it's important to properly prepare the soil. This may include adding compost or other amendments to improve the soil's texture and fertility.

You'll also want to make sure that the soil is well-draining, as tomatoes prefer slightly dry conditions. Consider using raised beds or installing drainage systems to prevent waterlogged soil.

Caring for High Tunnel Tomatoes

Once your tomatoes are planted, it's important to provide them with regular care to ensure optimal growth and yields.

This may include regularly fertilizing the soil, monitoring for pests and diseases, and pruning the plants to encourage proper growth and fruiting.

Conclusion

Planting high tunnel tomatoes can be a rewarding experience, but it's important to carefully consider your planting schedule and growing conditions. With the right timing and care, you can enjoy a bountiful harvest of delicious, home-grown tomatoes.
