Care Guide
Planting
Plant Conejo Buckwheat in full sun on a well-draining site; it thrives in rocky, clay-heavy soil but tolerates other soil types as long as drainage is adequate. Space plants about 0.5–1 meter (1.5–3 feet) wide, as this is their mature spread. Plant in spring or early fall to give roots time to establish before summer heat. Avoid low spots where water pools, since this rare buckwheat evolved on dry, open hillsides and won't tolerate soggy conditions.
After Planting
Water deeply but infrequently after planting - aim for established patterns by late summer or fall of year one. Once established, water no more than 3 times per month during summer, then taper off as temperatures cool. This plant is evergreen with no dormancy period and needs no pruning beyond removing dead wood. The most common mistake is overwatering; let the soil dry out between waterings and remember this plant evolved in rock crevices where water drains fast.
