How to save a flower if it dies
If the zamioculcas turns yellow, you need to urgently pull the plant out of the pot and carefully examine the leaves and roots. There should be no small pests on the crown. In the root system, all kinds of insects also like to start, which thrive on juicy tubers in moist warm ground. If pests have appeared on the plant, it is necessary to treat it with an insecticidal preparation, clean the foliage from insects with your hands, and cut out damaged tubers.
Due to the overflow of the tree, the roots of the plant begin to rot, the leaves do not receive sufficient nutrition, they begin to bend and turn yellow. In such cases, you need to remove the tuber damaged by rot, sprinkle the cut sites with activated charcoal and let the bush dry out, leaving it without soil for several days. In the future, watering is carried out no more than 2 times a week, the soil in the pot should dry out. In winter, you need to water once a month. If in doubt, whether the flower needs moisture, it is better to wait a few days. The plant tolerates drought well.
Healthy plant leaf
Even if zamioculcas is properly cared for at home, it turns yellow due to high humidity or, conversely, dry indoor air. In the first case, you need to move the pot to a more acceptable environment, preferably to a room with a few other plants. A dollar tree that grows indoors with dry air should be sprayed with a spray bottle.
If the rhizome is severely damaged by rot or most of the healthy shoots are not left on the surface, the plant is rescued by rooting its stems. A branch with green leaves is cut at an angle of 45 ° and placed in standing water for germination. When the roots appear, the cutting is planted in the soil for cacti.
Improper maintenance of the dollar tree
Some of the wrong flower care practices include the following:
- planting in heavy soil,
- lack of moisture, waterlogging;
- dampness in the room, dry air;
- too small a pot;
- lack of light, the presence of direct sunlight;
- cold temperature in the room.
To solve the problem, you need to establish the cause of the yellowed leaves. This is the only way to save the tree.
Succulent frostbite and sunburn
To understand why the leaves of zamiokulkas turn yellow, you need to pay attention to how much sunlight the flower receives. The best place in the apartment is the north or east side on the windowsill. If the tree is left in the open sun for several hours, it will get sunburn. When the flower is on the sunny side, the window is shaded with a curtain. It is not recommended to put the flowerpot in a dark corner, this can disrupt the processes of photosynthesis, and the leaves will begin to brighten, and leaf fall cannot be avoided.
Yellow leaf of zamiokulkas
It is worth remembering that zamioculcas is a culture imported from Africa, it requires light sandy soil, limited watering, and a temperature regime of 18 ° C. Being in drafts and in cold rooms leads to leaf fall. The culture also does not tolerate excessive fertilization. Top dressing is applied once every 2 weeks. It is useful to alternate organic fertilizers with mineral fertilizers.
Why is the dollar tree crying
The dollar tree can sometimes "cry", drops of moisture appear on the leaves. It is believed that zamioculcas "cries" before the rain. The scientific explanation for this is the special structure of the roots. The tubers cannot process all the liquid that was introduced into the soil during watering. Water is released onto the surface of the leaves and evaporates. Anything that did not evaporate due to the increased humidity of the air before the rain remains at the tip of the leaf. To see this effect, the room where the dollar tree grows must be very humid.
Dollar tree pests
The plant has good immunity to the invasion of parasites, however, it can suffer from aphids, spider mites and scale insects. To get rid of insects, the trunk and leaves of the tree are cleaned with a solution of household dust. Then they are treated with an insecticide. The soil is changed, since pest larvae can live in it.
The most difficult thing to get rid of is the scale insect, its smallest spores fly in the air. Periodically, you need to inspect the stems of the plant, the scale looks like bulging dark spots on the shoots of the flower. For prophylaxis, all diseased flowers are removed from the room.

Zamioculcas disease
Diseases can be transferred from new flowers that were purchased from hands or from unverified garden stores. A new tree should be quarantined for several weeks.
Common fungal diseases of the flower
If it is noticed that the stem and tubers turn brown in the plant, this may indicate a fungal infection. The best breeding ground for fungi is moist soil.
Anthracnose is a disease that loves high humidity. It manifests itself as focal darkening of the trunk. If you do not treat the dollar tree, it turns yellow more and more over time, as a result, the flower will die. Bordeaux liquid, colloidal sulfur are used to treat the bush.
Powdery mildew is a disease that often appears in the summer season with abundant watering of the flower. Symptoms are white bloom on the leaves. To get rid of the fungus, the shoots are treated with scor and topaz preparations.
Powdery mildew on the leaves
Sooty fungi - dark bloom on foliage. They appear as a result of the waste products of pests. First they fight insects, then they treat the bush with phytosporin from the fungus.
Bacterial diseases
Among the bacterial diseases of zamioculcas, the most dangerous are dry and wet rot.
Dry rot is usually transferred from the ground into which the flower is transplanted. It is expressed in the drying of tubers, when cut, foci of decay are visible. A sick bush with yellow leaves is taken out of the pot and examined for damage. Affected tubers are cut out, the sections are treated with a solution of potassium permanganate or a bactericidal preparation. The bush should be transplanted into a special soil purchased from a store.
Often, the underground part begins to rot if the tree is planted in unsuitable soil. The dollar tree loves light earths, the soil is best suited for cacti. You can make the mixture yourself. For this, sand, moss, soil and leafy ground are combined in equal proportions.
Symptoms of wet rot are expressed in yellow leaves, damage to the rhizome. The tubers become loose, may darken, and when pressed, release juice and an unpleasant odor. The wet rot bacteria can be carried from infected soil or from nearby plants. To combat the disease, the affected roots are removed, the rhizomes are soaked in a bactericidal solution. It is also worth sprinkling the tubers with ash and leaving to dry in a dry place.
Natural yellowing of foliage
Yellowing of old leaves, dying off of branches with a constant growth of new stems are considered normal. If new growth does not appear, and the leaves wither, the plant must be rescued. In case of significant damage, the flower is rejuvenated: a green branch is cut off and placed in cold boiled water. When the stem takes root, it is planted in prepared soil, after feeding it with fertilizers.
