What Soil Mix Works Best for a Rinzia crassifolia?

How Often Should You Fertilize a Rinzia crassifolia?

Feed Rinzia crassifolia every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

How Far Apart Should You Plant a Rinzia crassifolia?

Rinzia crassifolia can spread to about 3 ft (0.9 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.
