Diagnosing and Treating Brown Patches: Grubs, Fungus, and the Sugar Solution

Identify the Cause

Dig a spadeful of soil in a brown patch. If you see white, C-shaped grubs, it’s grub damage. If not, suspect brown patch fungus—especially if grass pulls up easily with few roots and a slimy base.

Organic Treatments

• Brown patch fungus: Spray 1 rounded tablespoon (≈4 tsp) baking soda per gallon of water. Saturate the area.
• Grubs: In an organic lawn, toads, lizards, and beneficial nematodes keep grubs in check. If populations are high, apply beneficial nematodes. Avoid chemical grub killers—they disrupt the natural predators.

The Sugar Program: Simple, Safe, Effective

Broadcast 1 lb sugar per 250 sq ft in spring (at green-up) and fall. Water in well. Sugar feeds beneficial soil microbes, which enrich the soil naturally. Weeds don’t thrive in rich soil; pests are controlled by the ecosystem you build. No burns, no risk to kids, pets, or asthma sufferers.

Bonus Organic Tips from Charlotte

• Indoor pests: Fresh rosemary on shelves, lavender at entrances, cedar oil on closet rods repel roaches, flies, moths, earwigs, silverfish, spiders.
• Fire ants: Chopped orange peels scattered over mounds make them relocate immediately. Broadcast peels yard-wide during swarm season.
• Cats in beds: Chopped lemon peels deter them.
• Earthworms: Buy a can of fishing worms and release them—they aerate and enrich soil.
• Alfalfa tea for blooms: 1 cup alfalfa meal + 1 tsp cider vinegar in 5 gallons water, steep overnight, water blooming plants.
