August in the Garden

Task List & Planting Guide

Garden Care

August is still brutal—but this is your transition month into fall success.

Continue deep watering 2–3x/week

Containers: 1-2x a day

Refresh mulch if it’s broken down

Watch for hydrophobic soil (water running off) → soak slowly

Cut back leggy annuals early August: Zinnias, cosmos, celosia

→ You’ll get a strong fall flush – Continue harvesting regularly

Remove anything fully spent or diseased

FALL PLANTING (KEY TASK)

Direct sow mid–late August:

Zinnias (fast fall crop), Sunflowers (short-season varieties), Cosmos

Vegetables & Herb Care

Tomatoes may start setting fruit again late August

Keep harvesting: Okra, melons, southern peas

Remove exhausted plants to make room for fall

Cut back and reshape: Basil, oregano, thyme

Replant basil if it’s too far gone

Tree & Shrub Care

Continue deep watering

Plan fall planting (but don’t plant yet unless temps ease late month)

Lawn Care

Maintain mowing height

Water deeply

Late August: you can start planning fall lawn care (not yet heavy fertilizing)

Pest & Problem Watch

Spider mites (still active)

Grasshoppers

Fungal issues if humidity increases

WEST TEXAS STRATEGY SHIFT – You’re preparing for fall dominance now

Start clearing space, refreshing beds, and planning succession

Shade structures can start coming off late month (weather depending)
