Choose the right plants

Selecting plants well-suited to your hardiness zone and local climate is critical for gardening success. Consult local gardening resources and nurseries for recommendations on the best varieties for your area.

Prepare the soil

Healthy soil is the foundation of a thriving garden. Test your soil to ensure it has the proper pH and nutrient levels to support plant growth. Amend your garden beds with organic matter, such as compost, to improve soil fertility and structure.

Start seeds indoors

To extend the growing season and protect tender plants from late frosts, start seeds indoors 4-6 weeks before the last expected frost date. This will give your plants a head start and help ensure a successful harvest.

Practice crop rotation

Rotating crops helps prevent the buildup of pests and diseases in your garden. Change the location of your plantings each year, grouping plants with similar needs and growing habits together.

Use organic pest control methods

Encourage beneficial insects, such as ladybugs and lacewings, by planting flowers and herbs in your garden. Practice companion planting to deter pests and utilize physical barriers, such as row covers, to protect vulnerable plants.

Conserve water

New Hampshire can experience periods of drought, making it essential to use water-saving techniques in your garden. Mulch your garden beds to retain soil moisture, and utilize drip irrigation or soaker hoses to deliver water directly to plant roots.

Prepare for winter

Proper winter preparation is crucial for the survival of your plants. Protect perennials and garden beds with mulch, and insulate tender plants with burlap or frost blankets to shield them from harsh winter conditions.
