Care Guide
Planting
Plant Lacy Phacelia in full sun with fast-draining, sandy soil - this is non-negotiable for success in the Bay Area. Since it's an annual with a fast growth rate, you can direct sow in spring during the blooming season (March–May) or plant transplants. Make sure the soil drains quickly; if your garden bed tends to stay wet, amend with sand or plant in a raised bed. Space plants to account for their 2–4 foot mature height.
After Planting
Once established, Lacy Phacelia is extremely drought-tolerant and needs water only about once a month during summer at most. The biggest mistake people make is overwatering - this plant actually prefers lean, dry conditions and will struggle in constantly moist soil. As an annual, it will naturally complete its lifecycle in one season; simply let it bloom through May and it will decline as temperatures heat up. Wear gloves when handling, as some people experience skin irritation from touching the foliage.
