Potentilla 'Arc-en-ciel'

Spring-Autumn · Outdoors

Water during dry periods

For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.

Spring - early-mid · Planting

Divide when too large

The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.

Summer-Autumn · Planting

Support tall stems

The plant may require support for long stems. Provide an artificial frame which it can grow through, or loosely tie the whole plant. A network of twigs can be woven together to provide a framework through which the plant can grow.

Tall stems can lean or be battered by weather. Support the plant to keep its vertical lines, aiming for a natural appearance which is easy on the eye.
