Understanding New Hampshire’s Growing Season
When planting tomatoes in New Hampshire, it’s essential to understand the region’s growing season. The average last frost date in the state varies by location but generally falls between late April and mid-May. This means that it’s best to wait until after the last frost to plant tomatoes.
However, it’s also essential to consider the average temperatures and frost risk in your specific location. The best time to plant tomatoes in New Hampshire is in late May or early June when the soil has warmed up, and the risk of frost has passed.
When should you start tomato seeds in New Hampshire?
If you plan on starting tomato seeds indoors, it’s important to time them correctly to ensure they are ready to be transplanted into your garden at the optimal time. To do this, count back 6-8 weeks from your preferred planting date to determine when to start your tomato seeds indoors.
Remember that tomato seeds typically germinate best at temperatures between 70-80°F, so be sure to provide a warm and well-lit environment for your seedlings.
Recommended Tomato Planting Dates in New Hampshire
| Location | Recommended Planting Dates |
|---|---|
| Coastal Region (Portsmouth, etc.) | May 25 – June 5 |
| Inland Region (Manchester, etc.) | June 1 – June 10 |
| Northern Region (Conway, etc.) | June 5 – June 15 |
These recommended planting dates are based on average temperatures and frost risk in each region, but it’s important to note that weather patterns can vary from year to year. Be sure to monitor the forecast and adjust your planting schedule as needed.
Choosing the Right Tomato Varieties
When growing tomatoes in New Hampshire, selecting a suitable variety is key to a successful harvest. The state’s excellent and short growing season and occasional extreme weather conditions can challenge tomato cultivation. However, carefully selecting and planning allows gardeners to enjoy a bountiful tomato season.
One of the critical factors to consider when choosing tomato varieties for New Hampshire is their ability to withstand cool temperatures. Look for “early” or “cold-hardy” tomatoes, which can tolerate cooler weather and have a shorter time to maturity. Examples of such varieties include Glacier, Stupice, and Sub-Arctic Plenty.
Disease-resistant varieties are also an excellent choice for New Hampshire gardeners, as they can help mitigate common tomato diseases such as verticillium wilt, blight, and mosaic virus. Popular disease-resistant tomato varieties include Mountain Merit, Iron Lady, and Defiant.
If you prefer heirloom tomatoes, there are also some suitable options for New Hampshire’s growing conditions. Varieties such as Black Krim, Brandywine, and Cherokee Purple have proven to perform well in the region’s climate.
Remember to consider your specific location and growing conditions when selecting tomato varieties. Some varieties may perform better in certain parts of the state than others. In general, it’s a good idea to choose a variety that is adapted to cooler and shorter growing seasons.
Preparing the Soil and Planting Tomatoes
Proper soil preparation is essential for successful tomato cultivation in New Hampshire. Before planting, test the soil pH and nutrient levels. Tomatoes prefer slightly acidic soil with a pH between 6.0 and 6.8. Amend the soil as needed with compost or fertilizer to ensure adequate nitrogen, phosphorus, and potassium levels.
When planting tomatoes, choose a site that receives at least six hours of sunlight daily and has well-draining soil. Plant tomato seedlings once the soil temperature reaches at least 60°F, typically in New Hampshire in late May or early June. Dig a hole slightly more profound than the root ball of the seedling and space plants 24 to 36 inches apart.

Support tomato plants, such as cages or stakes, to keep them upright and prevent fruit from touching the ground. Water tomato plants deeply once a week or more frequently during periods of drought. Avoid getting water on the leaves, as this can increase the disease risk.
Throughout the growing season, monitor tomato plants for signs of pests or disease. Common issues in New Hampshire include early blight, septoria leaf spot, and tomato hornworms. Remove any infected or infested foliage and treat it with an appropriate pesticide or fungicide.
As tomato plants grow, prune them by removing suckers — the small shoots that emerge from the joint where a branch meets the stem. This will encourage the plant to put energy into producing fruit rather than foliage. Additionally, pinching off the growing tip of the main stem once it has reached the desired height can help focus the plant’s energy on ripening existing fruit.
Following these tips for preparing the soil and planting tomatoes in New Hampshire, you’ll be on your way to a successful harvest of juicy, delicious tomatoes.
Maintaining and Caring for Tomato Plants
Once your tomato plants are in the ground, it’s essential to maintain and care for them properly to ensure a bountiful harvest. The following are some tips for maintaining and caring for your tomato plants in New Hampshire:
Watering
Tomatoes need consistent watering to thrive, especially during hot months. Aim to give your plants one to two inches of water each week, making sure to water deeply at the root level to encourage strong root growth. Avoid overhead watering, which can increase the risk of disease and fungal infections. Mulching around the base of the plants can help conserve moisture and regulate soil temperature.
Fertilizing
Fertilizing provides essential nutrients that help your tomato plants grow and produce fruit. Start by amending the soil with plenty of organic matter before planting, as this will slowly release nutrients over time. As the plants grow, you can supplement with regular balanced fertilizer applications, such as a 10-10-10 mix. Avoid over-fertilizing, as this can lead to excessive growth at the expense of fruit production.
Pests and Diseases
In New Hampshire, common tomato pests include hornworms, aphids, and flea beetles. Look for signs of infestation, such as chewed leaves or stunted growth, and use an appropriate insecticide or organic pest control method to manage the problem.
Also, monitor your plants for signs of disease, such as early or late blight. If detected, remove infected leaves or plants and treat the remaining plants with an appropriate fungicide.
Pruning
Pruning can help your tomato plants stay healthy and productive. Remove any suckers that appear between the main stem and the branches, as these can sap energy from the plant and reduce fruit production. Additionally, remove any lower leaves touching the soil to prevent disease risk.
Maximizing Yield
To maximize your tomato yield, try these tips:
- Support your plants with stakes, cages, or trellises to prevent sprawling and increase air circulation
- Harvest tomatoes when they’re firm and fully colored
- Store ripe tomatoes in a cool, dry place away from direct sunlight
- Rotate your crop each year to prevent disease buildup in the soil.
By following these tips, you’ll be well on your way to growing healthy, productive tomato plants in New Hampshire. Happy planting!
