Panicum virgatum 'Dallas Blues'

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 in dry periods

Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.

Spring - late · Planting

Divide when too large

When the plant is too large clumps may be divided into two or more pieces. Rhizomes can be cut, whilst small bulbs or offsets are detached. The new plants can be grown in a container or planted in the ground.

Winter - mid-late · Planting

Prune to the ground in winter

Cut foliage to the ground before new growth starts in spring.

Where stems are grown for ornamental value, they should be removed either before new growth starts in spring, or during winter when they begin to look ragged or untidy.
