Introduction

Tomatoes are one of the most popular vegetables grown in New Hampshire gardens. While there is no perfect time to plant tomatoes, understanding the ideal conditions for planting and growing can make all the difference in the success of your crop. In this article, we'll take a closer look at when to plant tomatoes in New Hampshire.

Climate Conditions in NH

New Hampshire climate varies by region, with the northern parts of the state cooler than the southern areas. However, the average frost-free date across the state is around May 15. This date signifies the end of the winter cold and the beginning of spring planting season.

When to Plant Tomatoes in NH

The ideal time to plant tomatoes in New Hampshire is just after the last expected frost. While it is tempting to plant them earlier, this may cause the plants to be damaged or killed by frost. Typically, this occurs in mid to late May in southern NH and early to mid-June in the northern regions.

Choosing Tomato Varieties

Choosing the right type of tomato variety is crucial for success in New Hampshire's climate. Look for tomato varieties that are bred for shorter growing seasons and colder climates. Cherry tomatoes and Early Girl varieties are popular choices due to their hardiness and quicker ripening time.

Preparing the Soil

Tomatoes grow best in well-drained, nutrient-rich soil. Prepare your soil by adding compost or manure a few weeks before planting to increase soil fertility. Make sure the soil has a pH of around 6.0 to 6.5, which is optimal for tomato growth.

Planting Techniques and Tips

To properly plant tomatoes, dig a hole that is about 2-3 times the size of the tomato transplant. Place the tomato plant in the hole and cover it with soil up to the first set of leaves. Water the plant thoroughly and add compost or mulch around the base for added moisture retention. Tomatoes also benefit from the use of a tomato cage for added support and protection.

Caring for Your Tomato Plants

To ensure optimal growth, tomato plants should be watered regularly, about 1-2 inches per week, and fertilized with a balanced vegetable fertilizer when the fruit begins to form. Proper pruning is also essential to promote air circulation and prevent disease. Remove any suckers that grow between the main stem and the branches.

Conclusion

In summary, the best time to plant tomatoes in New Hampshire is after the last frost, typically in mid to late May for southern ND and early to mid-June for northern areas. Remember to choose the right type of tomato variety, prepare the soil, and use proper planting and care techniques for a successful tomato harvest!
