When should I plant my garden in New Hampshire? ›

On average, your frost-free growing season starts May 7 and ends Oct 3, totalling 149 days. You will find both Spring and Fall planting guides on this page.

A planting schedule can be created by determining the first frost date and then working backwards. This will help figure out the best planting date for whatever you are growing. The goal is to ensure a plant has enough time to mature before the first frost of the year.

You can plant or harvest something from your garden almost all year. The two major planting periods, however, are spring (March to May) and fall (mid-July to September). The spring plantings are harvested in June and July, while the fall plantings are harvested from October to December.

Basil, cabbage, broccoli, carrots, parsnips, onions, peas and peppers, among many other veggies will flourish in New Hampshire growing zones. If looking for plants and flowers that thrive in the area, consider royal azaleas, hobblebush, rhododendrons, climbing hydrangea and star magnolia.

April is the best time to plant most of your vegetable seeds after your last frost. It's still not too late to plant tomatoes and peppers from seeds as well. Be sure to check your gardening zone for last frost dates.

Listen, it is never too late to start a garden because there are things that can always be growing in the garden, even when it's covered in snow.

If you didn't find time to plant a garden this spring, don't fret. It's not too late to plant a vegetable garden. Gardeners can plant vegetables in July and August for a fall harvest.

But the question so many people ask is: how late can I plant? The answer is you can plant as late into the season as you are able. That is, as long as you are able to get a spade into the ground you can plant or divide.

The hardiest of flowers can be planted as soon as the soil in your garden can be worked, even if it's several weeks before the last frost of the season. For half-hardy flowers, hold off until a couple weeks before the final frost, and for tender flowers, plant when there's no chance of frost for the rest of the season.

Planting vegetable seeds or transplants at the correct time is important to getting the most out of your garden. Knowing your first and last frost dates will help you start your vegetable seeds at the right time. New Hampshire is in USDA plant hardiness zones 3-6.

Time It Right

While it might be tempting to ship indoor plants outside at the first sign of spring, it's best to wait until nighttime temperatures stay at or above 60°F, and after any threat of frost has passed. If you're planning ahead, use the average last frost date for your area as your guide.

The best time to plant annuals, perennials, or mixtures of annuals and perennials is in the spring, early summer or very late fall. Fall plantings should be late enough so that seeds do not germinate until spring.
