Compost Timing and Weed Control Without Harming Bulbs

Marcia asks about applying compost in fall and using vinegar/alcohol for weeds near tulip bulbs.

Recommendations

• Compost: Wait until spring to fertilize, unless you garden in a frost‑free zone.
• Weed control: Avoid vinegar or alcohol near desirable plants; they are non‑selective and can damage bulbs and perennials.
• Pre‑emergent: Use a product like Preen to stop annual weed seeds from germinating (does not kill existing weeds).
• Mulch: Apply a good layer of cypress bark or similar mulch to suppress weeds.
