Embracing the Coastal Climate: Key Considerations

The climate on Dewees Island is characterized by warm, humid summers and mild winters. This means your landscaping needs will differ from those on the mainland. Key considerations include:

* Salt Tolerance: Many plants need to be salt-tolerant due to proximity to the ocean. Native species are often the best choice as they are adapted to these conditions.

* Wind Resistance: Coastal winds can be strong. Choosing plants that can withstand wind or creating windbreaks is essential.

* Soil Type: Island soils can be sandy and may require amendments to retain moisture and nutrients.

* Water Management: While rainfall is common, efficient watering practices are still important, especially during drier spells.

Spring (March - May): Awakening the Island Garden

Spring is a time of growth and renewal on Dewees Island. Focus on preparing your garden for the warmer months and encouraging new blooms.

* March:

* Lawn Care: Fertilize your lawn with a slow-release, nitrogen-rich fertilizer. Aerate and overseed any bare spots. Start mowing as needed, but avoid cutting too short.

* Gardening: Prune any remaining dead or damaged branches from shrubs and trees. Plant cool-season vegetables and flowers (e.g., pansies, snapdragons, lettuce, spinach). Begin weeding proactively.

* Mulching: Apply a fresh layer of mulch to garden beds to retain moisture and suppress weeds.

* April:

* Lawn Care: Continue mowing regularly. Apply a pre-emergent herbicide to prevent crabgrass if needed.

* Gardening: Plant warm-season annuals and perennials (e.g., petunias, marigolds, impatiens). Start seeds for heat-loving vegetables like tomatoes and peppers indoors or in a protected area.

* Pest Control: Monitor for early signs of insect pests and address them promptly.

* May:

* Lawn Care: Adjust mowing height to slightly higher to help shade the soil and retain moisture. Watch for chinch bugs.

* Gardening: Transplant warm-season vegetable seedlings into the garden. Fertilize flowering shrubs and perennials.

* Watering: Begin a consistent watering schedule, especially during dry periods, focusing on early morning or late evening.

* Gardening: Plant native trees and shrubs. Protect sensitive plants from frost. Water evergreens thoroughly before the first hard freeze.

Winter (December - February): Dormancy and Planning

Winter on Dewees Island is a time for rest for your landscape, but it's also an excellent period for planning and maintenance.

* December:

* Lawn Care: Keep off the lawn when frozen to prevent damage. Clear any debris.
