How much to water

The zamioculcas is an ornamental plant suitable for living in any area of ​​the house. It does not like water stagnation, which can cause root rot, so it is advisable to empty the saucer from excess water after watering. The water needs are very variable depending on the area where the plant is located: if it is exposed in very bright areas (the sun’s rays must never hit the leaves directly because they could burn them), then the amount of water to be administer to the plant will be higher, especially in summer and in hot periods; if the plant is instead in places of the house in dim light, the quantity of water must be limited since the vegetative activity is reduced. In any case, the limit of one irrigation per week should not be exceeded.

Care to be provided

The zamioculcas has the great advantage that it does not require special care, and this prerogative has contributed decisively to its spread. It is advisable to manually eliminate damaged or withered leaves, so as to prevent them from becoming a vehicle for diseases and parasites; the elimination of the damaged parts also has the great advantage of stimulating the growth of new branches and new leaves, starting from the buds exposed to the surrounding air, more resistant than the previous ones and in a relatively short time. It can tolerate both very cold temperatures, down to -15 ° C, and very high temperatures, above 30 ° C. In the first case, however, the zamioculcas will react by eliminating all the leaves, which will grow back as soon as conditions return favorable. In spring and summer, it can be taken outdoors,


The zamioculcas, thanks to its resistance, can tolerate the absence of fertilizer even for many months. However, this situation is inadvisable because it would cause the leaves to fall and cause the plant to lose all its beauty. For this reason, at least once a month throughout the spring and summer, it is advisable to dissolve some fertilizer in small volumes of water, to be administered to the plant. The fertilizer to be used can be easily purchased in a specialized shop, and must contain both macro elements such as nitrogen, phosphorus and potassium, and minerals such as iron, magnesium, copper, manganese, molybdenum and zinc. It is advisable for the fertilizer to be slow-release, in order to guarantee protection to the plant against the following winter’s freezing.

Zamioculcas: Diseases and parasites

The main threat to this plant is represented by the presence of damaged, blackened or yellowed leaves (the latter condition is a consequence of an excess of water) still tied to the trunk. These leaves can in fact become a vehicle for diseases and fungi, and represent a vulnerability point for attack by small parasites such as scale insects, which appear with black spots on the page. To this end, the importance of eliminating damaged parts for preventive purposes is emphasized. In case of attack by the scale insects, it is possible to proceed following different ways, according to the extent of the attack: if there are only a few adult specimens on the zamioculcas these can be eliminated by soaking a cotton swab in ethyl alcohol and proceeding with manual removal; if the attack is much more extensive, it is advisable to use a specific pesticide.
