McKay's White Potentilla Care
Potentilla needs full sun for best results. This plant has average water needs and likes damp conditions, so give it a drink when the top layer of soil feels dry. Soil with high organic content will support healthy growth. The ideal soil will also be moist but allow for good drainage.
Feed this shrub using balanced plant food with a ratio like 10-10-10. You can also support healthy growth by applying a layer of organic compost around the base of the plant. Trim away old growth after the flowers fade to encourage more growth.
McKay's White Potentilla Spacing
McKay's White Potentilla has a compact size and grows 2 to 3 feet tall and wide. When creating a hedge, shrubs can be planted as close as 2 to 3 feet.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
- When to Prune
