Zamioculkas is a beautiful ornamental shrub from the Aroid family. This evergreen ornamental plant with a gorgeous crown and dark green foliage. But after a certain period after the zamiokulkas was planted in open ground, its leaves turn yellow. In this article we will look at why this is happening, and also figure out how to deal with the problem.
Dark spots on zamiokulkas leaves: what to do?
Zamiokulkas, like all other ornamental plants, have diseases: dark spots can appear on its leaves. Such a nuisance happens if the shrub was in a low temperature for a long time or stood in a draft. Also, excessive watering leads to leaf darkening. The way out of this situation is quite simple: it is necessary to bring the heat and water regimes back to normal, eliminate the stagnation of the liquid and stop overwetting.
How to cure a plant from root rot
If the zamiokulkas had dark spots on the stem, this is the first sign of root rot. The cause of rotting of the root system, rolling on the trunk, is excessive watering at low temperatures.
Important! Zamioculkas loves warmth, but does not tolerate heat. Humidity needs to be maintained also moderate, but the plant tolerates drought. It can be compared with a camel, since nature has prepared a zamiokulkas for the possibility of accumulating water in reserve.
Heavy clay soil can not provide good drainage and effective ventilation, and therefore root and stem rot occurs. For this reason, the bush most often dies. But it is still possible to save the first days, if you dig up a tuber and remove all the affected processes, and sprinkle the slices with ground coal. If the zamiokulkas are sick and dark spots appear on the trunk, then the whole plant, including the roots, needs to be treated with broad-spectrum fungicides, for example, Oxyf or Fundazol. Then plant in a new pot with completely replaced soil. If the process of decay is already irreversible, then the tuber must be cut off and discarded, and the leaves used for further reproduction.Did you know?
