Autumn · Planting

Remove offsets to create new plants

Offsets are small plants or shoots that develop around the parent plant. They should have developed a root system of their own before they are detached. They can be planted directly, or grown in pots if so small they could be 'lost' in the garden.

Spring-Autumn · Indoors

Feed with houseplant feed

From spring until autumn feed weekly with a half strength balanced houseplant fertiliser.

Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), choose one where nitrogen has a high value.

Spring-Autumn · Indoors

Water regularly during growth

Water regularly while in growth.

Adopt a regime that means the plants are thoroughly watered every week so that they do not become dessicated. In hot weather watering may need to be more frequent, but less often in cool or moist conditions.

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.

Winter · Indoors

Water lightly during dormancy

The soil should be kept just moist during the plant's rest period.

Indoors

Water some varieties differently

Some plant varieties within this genus have additional requirements for water. It is best to look up your specific plant, or the species it belongs to for watering guidance, and/or check the label.

Outdoors

Feed & mulch some rose varieties differently

To keep roses healthy and produce more flowers, feed during the growing season before and after flowering. Roses in containers should be fed more often than those planted in the ground, every two weeks from mid spring to late summer. Adding a mulch around the base of a rose will trap moisture and enrich the soil as it biodegrades.
