Fall Lawn Care Sequence: Seed, Fertilize, Weed Control (Toronto)

Fall tasks: seed sparse spots, apply three-way broadleaf weed killer, fertilize. Need specific order and timing for Toronto.

Recommended Order

1. Prepare area: Clean, square out (rectangular shape for whole sod pieces), loosen soil.
2. Sow seed.
3. Fertilize ONLY after germination and rooting (typically 3–4 weeks). Starter fertilizer high in phosphorus.
4. Stop extra watering once established.
5. Apply weed killer (Trimec-type) ONLY after satisfactory germination and rooting. One component inhibits seed germination.

Final Mowing Before Snow

Mow slightly higher than normal. More leaf area = more carbohydrate storage for spring. For weed control, more leaf area improves herbicide uptake (especially on perennials).

“Square Out” Defined

Finish repaired areas to rectangular shapes that fit whole sod pieces. Narrow strips and odd shapes dry out and die.
