Sempervivum ciliosum

Spring · Indoors

Feed with low nitrogen feed

Occasionally while the plant is in growth, apply a specialist cactus feed that is low in nitrogen.

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 low value.

Spring-Winter · Indoors

Water spring-autumn when compost is dry, sparingly in winter

Water when the compost is dry, allowing the compost to dry between waterings. Water the plant sparingly in winter, dribble a little water onto the compost every now and again, so that it stops growing and has a "rest period".

Spring-Winter · Indoors

Soak completely when watering

Water until water comes out of the bottom of the pot. Leave for 30 minutes or so until the compost is fully moist, then pour away the excess water so the plant pot is not standing in water. (This avoids waterlogging which can cause "root rot".)

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 - early-mid · Planting

Divide when too large

The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.

0C minimum temperature

This plant requires a minimum temperature of 0 Centigrade.

Compost · Planting

Cactus compost for repotting

Use standard cactus compost. Top the soil with grit or granite chips to ensure perfect drainage around plant stem. Repot when the plant is dry and delay watering for 3 days after repotting.

You can also make own compost using 3 parts John Innes no. 2, 1 part horticultural grit, and 1 part horticultural grade perlite or pumice. There are many 'recipes' available and opinions vary widely - consult specialist literature or websites.

Indoor plant · Planting

Position in a sunny spot, close to window

Give this plant a position where there is as much light and sunlight as possible, within 2-3 metres of a sunny or bright window (one that is south, east, or west facing).
