CULTURAL
INFORMATION
LIGHT Always remember that cactus
needs as much sunlight as possible all year round. Most will grow quite
adequately on a sunny window. But if you would like ideal conditions it is best
to grow your plants under cover with full sun. A greenhouse is easily the best
option, but it is also possible to grow plants outdoors using various forms of
temporary cover. Growing cacti outdoors without cover (in our UK climate) is a
daunting task, and if contemplated, it is best done during the growing season.
If left outside during the winter very few cacti will survive. Most plants will
be seriously damaged. If you have to, choose a spot very well protected from
the elements, wind, rain and cold.
WATER/ FEEDING Regular watering
and feeding should take place during the growing season (April – September).
After watering they should be allowed to dry out completely before watering
again. Cactus feed is available at most garden centre. You can choose from
food in powdered form diluted in water (at least once a month), or once a year
with a slow-release granular, cactus fertilizer.
WINTER During the winter all plants
should be given a rest (December to February), and kept very dry and cool (7 -
10 degrees is ideal). If kept above 15 degrees in a regular room they should be
watered sparingly to prevent them from shrivelling (every three or four
weeks). Please note that wet and damp plants kept at a low temperature during
the winter are liable to rot.
COMPOST When re-potting plants use a
gritty mixture, as this will allow water to drain through very easily.
Different cactus mixes are available commercially, but you can make your own by
combining two parts of soil with one part grit.
PEST AND DISEASES The
best method is, of course, prevention. Take time to inspect each plant
regularly. All desert plants are superbly equipped to adapt to a life in
‘captivity’ but sometimes they become the target of mealy bugs, aphids, scale or
fungus disease from growing conditions. There are natural and chemical ways to
remedy the situation. There are lots of pesticides and fungicides, which are
commercially available. Follow instructions carefully when
applying.
REPOTTING Plants need re-potting at
least every two years, and in some cases every year. Always choose a pot one or
two inches larger than the last. Be careful that the roots of the plants are
not damaged in moving. Cover the plant carefully with fresh soil, and press
firmly all around it until it reaches one inch from the top. Please leave for a
few days before watering.

information for the growing of cacti/succulents.
