When Should I Plant Tomatoes in NH?

Tomatoes are a favorite crop for many gardeners in New Hampshire. They are relatively easy to grow and provide a bountiful harvest if planted at the right time. But when exactly is that time? In this article, we will explore the best time to plant tomatoes in NH and the factors that affect their growth and yield.

Climate and Soil Type

The first thing to consider when planting tomatoes is the climate and soil type of your area. In NH, the climate is generally cool and humid, with a growing season that begins in late May or early June and ends in September or October. The best soil for tomatoes is well-draining and rich in organic matter, and the pH level should be around 6.0 to 6.8.

If you plant your tomatoes too early, they may not survive the frosty nights or cold soil temperatures. On the other hand, if you plant them too late, they may struggle to mature and produce fruit before the end of the growing season. Therefore, it is essential to plant tomatoes at the right time to ensure optimal growth and yield.

Planting Time

The best time to plant tomatoes in NH is when the soil has warmed up to at least 55°F, and the danger of frost has passed. This generally occurs around Memorial Day or the end of May in most parts of the state. Planting at this time ensures that your seedlings have plenty of time to mature and produce fruit before the end of the growing season.

If you prefer to start your tomatoes from seeds, it is recommended to do so indoors 6-8 weeks before the planting date. This will give you a head start and allow you to transplant the seedlings outdoors when the conditions are right.

Choosing the Right Varieties

Another important factor to consider when planting tomatoes is choosing the right varieties for your area. Some tomatoes are better adapted to cooler climates, while others do well in hot and humid conditions. In NH, some of the best varieties to consider include Early Girl, Jetsetter, Celebrity, and Roma, among others.

You should also consider the type of tomato you want to plant, such as determinate or indeterminate. Determinate tomatoes are typically smaller and bushier, while indeterminate tomatoes are vining and can grow very tall. Determinate tomatoes are a good choice if you have limited space, while indeterminate tomatoes are ideal for larger gardens.

Caring for Your Tomato Plants

Once you have planted your tomato seedlings, it is important to care for them properly. Water them regularly to ensure that the soil stays moist but not waterlogged. Fertilize them with a balanced fertilizer every few weeks to provide them with the nutrients they need to grow and produce fruit.

You may also need to provide some support for your tomato plants, especially if you have chosen an indeterminate variety. Staking or trellising can help keep the plants upright and ensure that the fruit stays off the ground, reducing the risk of rot and disease.

Conclusion

In conclusion, the best time to plant tomatoes in NH is when the soil has warmed up to at least 55°F, and the danger of frost has passed. Choosing the right varieties and caring for your plants properly can ensure optimal growth and yield, allowing you to enjoy a bountiful harvest of delicious, fresh tomatoes all season long.
