Care Guide
Planting
Plant Bush Seepweed in full sun where it can drain fast - this plant thrives in rocky, sandy, or gravelly soil and actually tolerates saline and alkaline conditions that would kill most plants. Spring is your best window for planting. Space it with room to spread, as this shrub can reach 3–5 feet tall with many spreading branches.
After Planting
Water moderately through your first summer, keeping the soil moist as it establishes, then gradually reduce watering as the plant matures and taps into deeper moisture. This is a moderate-care plant that's fairly forgiving once established; your main mistake would be overwatering or planting it in poorly draining soil, which invites root rot. Expect flowers in spring, and prune only if needed to manage its shape - the plant itself requires little fussing.
