How to grow succulents

Many gardeners choose to grow succulents in pots in a conservatory or greenhouse, so they can be moved in and out as the seasons change, to avoid frost damage. However, succulents can also be grown outdoors all year where conditions – or dogged refusal to accept defeat – allow.

A south-facing wall with free-draining soil is ideal, and the use of shelters and horticultural fleece will allow many succulents to survive even hard UK winters. Many can cope with quite cold conditions, being used to extreme temperatures in their native ranges – but do take care to not let them get waterlogged in winter.

If you want to grow succulents indoors, you’ll need a really bright location, such as a windowsill. While some succulents grow leggy if grown indoors for long periods (Echeveria and Aeonium), others have evolved to thrive underneath other larger plants, so can deal with being inside in an airy spot. Succulents suitable as house plants include: Crassula ovata (jade plant), Aloe vera, Haworthia fasciata (zebra plant), Gasteria and Kalanchoe tomentosa(panda plant)

Despite being adapted to drought and high light levels, many succulents grow in quite shady spots in their native ranges.

The ideal place for them at home would be a bright spot that gets sun for most of the day, but you should keep an eye on your plants on hot days.

Some succulents can even scorch in strong sunlight, especially in conservatories or greenhouses, leading them to close up their rosettes for the summer and become dormant. Artificial shading can help prevent this heat stress. 

Succulents’ tolerance for drought means they can be safely left while you go on your summer holiday. That said, they will appreciate regular watering in dry summer weather. The general rule is to allow the pot to get quite dry and then thoroughly re-soak the compost. With good watering and shading you should be able to extend the natural growing season of many succulents beyond the shoulder months of the summer.

The amounts of light and water that a succulent gets throughout the year can have dramatic effects on a succulent’s colour. In winter, they are quite green, but as light levels increase, coloured forms take on their darker tones. When stressed by lack of water, even green succulents take on red, pink and yellow tints. Often this is when they look most dazzling. That’ one of the delights of growing succulents, but can also make you wonder if your label is correct! 

As a rule of thumb, plants stay restricted to the root space given to them. Even an Echeveria or Sedum that would normally grow quite large will quite happily hold at a smaller size when planted into a smaller pot. But remember: for that exotic effect in borders you need big plants, and for this you need big pots!

In the wild, many succulents grow at high altitudes with heavy rainfall, but with rapid drainage too. Others have evolved to survive in very dry environments. Recreate this natural habitat when potting up by adding a third of coarse sand, grit or perlite to two-thirds of compost.

If keeping plants in a pot over winter, change the compost in spring. Do this by lifting the plant out of its pot, knock most of the old compost off the root ball and replant. This is especially important for plants in small pots. 

Where plants have become leggy, a length of stem can be buried and it will root easily.

If a plant becomes too tall or you’d just like to propagate more, cut off a rosette with a 10cm stem, insert it into some gritty compost and it will root easily.

This is best done in late spring or early autumn. Some succulents produce offsets or ‘pups’ by themselves, which develop into new plants.
