Rudbeckia triloba 'Prairie Glow'

Autumn - late · Outdoors

Apply mulch

Spread organic material around the plant being careful not to bury its crown, or to put the mulch above the point at which the plant has been grafted in the case of trees.

A mulch is a covering that can: protect the soil surface from rain, heat and cold; deter weeds; provide nutrients. Organic indicates that material has vegetative origin e.g. manure, compost. Synthetics i.e. plastics, or stones are often called mulches.

Autumn · Planting

Prune foliage back

Cut foliage back to the ground in autumn.

Spring - late · Outdoors

Apply slow release fertiliser

Apply a slow release fertiliser which is spread around the root area of 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.

Spring-Autumn · Outdoors

Water frequently to keep the soil moist

The plant thrives in moist or boggy soil, doesn't tolerate dryness and should be watered frequently, not only after a period of drought, but if the soil begins to dry out spring to autumn. Check plants in pots more frequently, especially in hot weather.

Summer - late · Planting

Divide the plant

Divide the plant and throw away any poor or weak growth. Immediately replant the divided portions.

Planting

Deadhead blooms during flowering season

Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.

The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.

Compost · Planting

Multi-purpose compost

Use a good quality peat-free multi-purpose compost when growing in pots and containers.
