The cactus is probably one of the most misunderstood plants. Often seen as a spiky thing that thrives on neglect, the cactus can in fact make an incredible landscape or potted plant.
Although the majority of cactus plants don't appear to have leaves, they actually do, but we call them spines—these are actually heavily modified leaves. These spines are the difference between a cactus and a succulent. A succulent that has thorns or spines on its leaf ends or margins is not a cactus.
Cacti respond very actively to their environment. Many have a short growing season that is synchronised with the ideal growing conditions. A cactus tends to be shallow rooted—this allows it to quickly take up any moisture in the soil from rain or dew. It can have rapid growth surges, or even burst into flower, after heavy rains.
The body of a cactus is technically its stem or trunk. Often green, grey or bluish in colour, it photosynthesises with this.
The appearance of a cactus can vary enormously, from globe shaped to column form to tree-like branched forms. Cactus flowers are simply stunning. They are often very short lived, but their colours include white, yellow, red, magenta and just about every other colour blend you can imagine. Most will not flower with regularity. They may flower like clockwork, or in response to heavy rain after a dry period, or they may only flower every few years, seemingly at random.
A cactus can be used in many ways, such as:
Your cactus will likely come with detailed care instructions on the label. Keep hold of the information for later reference. Your cactus will thrive in full sun positions. Most types must have very open, sandy free-draining soil—putting a cactus into regular garden soil or potting mix will kill it very quickly. You may need to create an elevated bed or rockery filled with this type of soil. If planting your cactus in a pot, use a specialised cactus potting mix.
During peak growth times and the warmer months, water your cactus regularly, but allow it to dry out between waterings. In winter, when the cactus is dormant, only water very lightly when dry.
Your cactus does not need to be feed, however an annual application of a controlled-release fertiliser at half rates will give you healthier plants and increase the likelihood of flowering.
Do not try to push the roots deep into the planting hole or pot. A cactus is shallow rooted.
To make planting, potting or re-potting a cactus a less painful experience, wrap newspaper six or eight layers thick around the part of the plant you plan to handle and secure it with sticky tape. Remove once planted.
The most common cause of cactus death in the home garden will be overwatering. Follow the general tips above and any specific instructions on the label.
There is a lot of variation as to which method will be most appropriate, depending on your cactus. As a general guide:
