Yellow Patches in Fall-Planted Fescue: Causes and Solutions

Yellow Patches = Cold Temperature Response

Yellow patches in fall-planted fescue are not disease. Cold temperatures halt photosynthesis. A few warm days in mid-December restart growth and yellow disappears.

Late Fall Fertilization

If second fertilizer round delayed, use "fast release" 16-4-8—water-soluble nutrients available after rain.

Late Seeding (After October)

Slow germination; will look fine by February. No extra fertilizer needed.

Summer-Planted Fescue Struggles

Q: Planted fescue in June, looks yellow. Replant, fertilize, or kill weeds?
A: Fertilize now (6 lbs 16-4-8/1,000 sq ft) and again in February. Leave weeds alone. If bare spots in March, reseed (max 4 lbs/1,000 sq ft). No weedkiller until 4 spring mowings.
