What Soil Mix Works Best for a Dream Herb?

Well-draining sandy loam with added perlite for improved drainage. Good drainage is essential for Dream Herb to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Dream Herb?

Feed Dream Herb 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.

Where Should You Plant a Dream Herb?

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

How Far Apart Should You Plant a Dream Herb?

Dream Herb can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.
