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 · 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-Autumn · Indoors

Water houseplant when dry

Let the soil dry between waterings and then water thoroughly. Don't leave the plant standing in water, and try to avoid splashing the foliage on hot sunny days or it could cause the leaves to burn.

Spring - late · Outdoors

Feed with sequestrol

If plants are acid loving and grown in soil with little acidity, or in a container, or are watered with limey tap water an annual feed with sequestrol (iron chelate) is highly beneficial. Follow guidelines on the packet. Will also 'blue-up' hydrangeas.

For hydrangeas that have good blue flowers in acid soil, this product can be used with alkaline soil to turn the flowers blue. This is most effective when the soil is neutral or just slightkly alkaline.

Spring-Autumn · Outdoors

Water during drought

In drought conditions where established plants in the ground have had no water for a month, do a deep watering. If drought continues repeat after a fortnight. Plants only need watering during spring to autumn growth. Check plants in pots more often.

Established plants are drought tolerant but benefit from water after a month or so. Ensure that water does not sit around the base of the plant which can cause rotting. Pebbles and stones tucked round its base can be beneficial.

Outdoors

Water with rain water

This plant needs rain water or soft water (the minerals in alkaline or "hard" water are harmful). This is especially important for plants in pots.

Indoor temperature · Planting

5C minimum temperature

This plant requires a minimum temperature of 5 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).
