Organic Lawn and Landscape Care: A Seasonal Schedule for Healthier Grounds

Organic Care Is Mainstream and Effective

Natural lawn and landscape products are widely available for DIYers, and many professional services now offer organic programs. A basic seasonal schedule ensures a gorgeous, pest-free landscape.

Winter (Jan–Feb): Dormant Oil Application

Horticultural oil suffocates overwintering pests (scale, spider mites). Apply when temps stay above 50°F for 24+ hours. Avoid contact with annual flowers.

Late Winter (Feb–Mar): Aeration

Liquid aeration (soil microbes + humates) or mechanical core aeration improves water, oxygen, and nutrient absorption. Especially beneficial for winter-damaged St. Augustine grass.

Early Winter: Potassium-Rich Fertilizer

Fertilize with potassium, magnesium, sulfur to store nutrients for spring growth. Dormant lawns still need root support through winter.

Spring: Natural Fertilizers and Sulfur

Microbes break down organic fertilizers slowly—no burn risk, no runoff. Acid-loving plants (azaleas, hollies, photinias) benefit from organic sulfur. Repeat Sept–Nov for summer recovery and fall prep.

Better for Environment, Same Effort

Organic methods match conventional in time, cost, and difficulty—while being safer and ecologically superior. Diamond Lawn Service (Addison, TX) has delivered family-owned organic care since 1983.
