Managing Weeds and Fertility in a Partially Shaded California Lawn

Shade Grass Selection

• Dry shade: 30–50% shade-tolerant Kentucky bluegrass (Bensun, Glade, etc.) + 50–70% fine fescue or tall fescue blend.
• Wet shade: 70%+ rough bluegrass + remainder shade-tolerant Kentucky bluegrass.

Weed Control

Yellow-flowered weed (oxalis or clover) is shade-loving. Ortho Weed-B-Gon works on broadleaves. Take sample to Cooperative Extension for precise ID and recommendation.

Fertilization & Seeding

• Fall is best for cool-season grass seeding.
• Fertilize shade areas at 1–2 lb N/1000 sq ft/year (half of full sun rate).
• Don't worry about exact color match; focus on stand density first.
