ðą How to Care for Cheddar Pink to Prevent Leaf Spot?

Water deeply but infrequently, letting the top of the soil dry out between waterings. Established plants are quite drought tolerant; the biggest threat is overwatering, which leads to crown and root rot.
âïļ Lighting
Needs full sun â at least 6 hours of direct light a day â to keep its mat compact and flower heavily. Tolerates light afternoon shade in hot climates but gets leggy in shade.
ðŠī Ideal Soil
Plant in loose, sharply-draining, neutral to alkaline soil (chalky or limy soils are ideal). Heavy, wet clay is the main cause of failure; amend with grit or sand if drainage is poor.
