About this plant
A neat and delightful early flowering Astilbe. This has conical heads of frothy flowers that are coloured a clear white. The flowers taper to a point and have upward arching side-branches, so appear a little like the shape of a classic Christmas tree. The flowers are likely to be a feature during late June and July, perhaps going into August. The foliage mound beneath is attractive and is coloured dark green. This looks beautiful with ferns and is handsome by water.

AutumnNow
Autumn - late · Planting
Divide every 3 years
Physically divide clumps every three years, or the plant will flower and grow less well. Discard or give away unwanted portions, or replant them to make a larger display. Plants can sometimes take a while to recover from this procedure.
Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming 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.
Spring-Autumn · Outdoors
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.
