Planting Knockout Roses in Clay Soil: Amend Heavily

Don't Plant Directly in Clay

Upstate NY gardener wants to plant two pink Knockouts in clay soil. Cousin suggests peat moss, grass clippings, banana peels, Miracle-Gro.

Proper Planting Protocol

1. Hole 2× container size.
2. Backfill with best organic potting soil (e.g., Happy Frog).
3. Amend hole with: 1 cup rock dust, max coffee grounds, 1–2 cups liquid seaweed.
4. Fill with water, let drain to muddy.
5. Plant at same level as in pot.
6. Water in well, top-dress with potting soil, thin acid mulch.
7. Drip/soaker irrigation only.
8. Min 6–8 hrs sun.
9. Winter protection (cover).

Red vs. Pink

Both lovely. Red may fade to pink in heat. Regular organic feeding essential.
