February may look quiet in Southern New Hampshire gardens, but it is one of the most important months for setting up a healthy spring. Late winter is the ideal time for expert pruning, tool preparation, shrub health checks, and early seed planning, especially in Zone 6b Seacoast conditions.

Limelight Hydrangeas are one of the most rewarding shrubs you can grow on the Seacoast—but sandy soils, salt wind, and Zone 6b winters mean the details matter. Learn how to plant, prune, and care for Limelights the right way, with expert guidance rooted in the coastal conditions of Portsmouth, Rye, Exeter, and beyond.

Seacoast soils in Zone 6b range from sandy and fast draining near Portsmouth and North Hampton to heavier, compacted ground around Exeter. Preparing early with compost, organic fertilizers, and quality mulch ensures you are ready when the soil becomes workable. Thoughtful soil preparation sets the stage for stronger roots, healthier plants, and a more resilient garden all season long.

Greenhouses and cold frames both help extend the growing season in Zone 6b, but each serves a different purpose. While a greenhouse offers a fully enclosed, temperature controlled space for starting seeds and growing tender plants, a cold frame provides simple protection for hardening off seedlings and extending spring and fall harvests. Understanding the difference helps Seacoast gardeners make the most of every growing season.
