GROWING INSTRUCTIONS

When growing lithops it is wise to always bear in mind the conditions of heat and drought under which they grow in the wild. It is also important to accept that they are very slow growing and can often take several years to achieve adult proportions. Nearly all problems occur as a result of overwatering and poor ventilation especially when weather conditions are dull and cool or very humid. They require the maximum amount of light you are able to give them. The ideal growing situation is a south facing greenhouse (vice versa in the southern hemisphere). Failing this a south facing conservatory or windowsill should be adequate. If the plants don't get sufficient light they will grow tall and lose their compact, stone-like appearance. They will also be weaker and far more likely to succumb to overwatering. Lithops can tolerate very high temperatures as long as there is plenty of fresh air. They do not survive for long in stagnant conditions. If these criteria can be met then it should be possible to maintain a healthy collection of lithops for many years.
Any watering of the plants should have stopped before frosts begin to occur. Lithops should be left totally dry throughout winter and spring. During this period the plant will generate a new body (or pair of bodies). The new body will consume the moisture and nutrients of the previous body as it completes its growth. This process should be visible by early spring. Throughout the winter and spring keep the plants cool but avoid freezing. Watering can commence once the remains of the old plant body are shrivelled and drying. This can be any time during May to July depending on variety. When watering soak the compost fully. The remains of the old bodies and any flower stems can be carefully removed when they have become thoroughly dry....small scissors and tweezers are useful for this.
