Brown Patch, Grubs, and Yellowing Under Oak: Compost Tea Rescue

Oak Tree = No Grass Zone

Oaks outcompete grass for water, nutrients, light. Replace grass under dripline with mulch, ground covers (pachysandra, hostas), and a bird feeder/bath.

Chemical Lawn = Disease Magnet

Grubs, brown patch, yellowing = “Chemicals Disease.” Synthetics kill microbes, earthworms, birds—the natural controls. Untreated neighbor lawns often look better.

Compost Tea Recipe (Alaska Humus)

1. 1 shovel humus in 5-gal rainwater.
2. Optional: 2–3 tbsp molasses/sugar + few cups fruit, cornmeal, Epsom salts, weeds, fish, soil, vinegar, alfalfa meal.
3. Stir daily 1 week; use when foamy.
4. Drench or spray lawn.

Cornell Proof

Dr. Eric B. Nelson: Compost tea’s long-term disease control equals/exceeds fungicides, reduces pathogen populations (fungicides don’t), and improves turf quality more.

Immediate Action

• Stop all chemicals.
• Spread humus bags over lawn for winter.
• Start tea applications in spring.
