Sollya heterophylla 'Ultra Blue'

Autumn - late · Outdoors

Apply a protective mulch

Protect the crown of the plant in winter in areas that are prone to frost and cold. For short term protection a fleece can be used, otherwise fill mesh sacks with masses of straw and secure them over the plant's crown.

The 'traditional method' is to put wire or other netting over the plant, layer plenty of straw on top of this and then secure the whole with more netting.

Water to keep the soil moist

For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.

Without regular watering some plants never fully regain their beauty.

Summer - early · Outdoors

Apply slow release fertiliser

Apply a slow release fertiliser which is spread around the root area of the plants soon after they have come into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

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.

Winter - late · Planting

Prune to maintain the plant

Generally reduce the plant in size by cutting back all the spreading branches and shoots, so there are only 3 or 4 buds on each stalk.
