Why Zamioculcas does not give new shoots?
The reason that the leaves of zamiokulkas turn yellow, lose their rich green color, or even wither, is often a lack of light. Unfortunately, flower growers forget about the change in illumination in the autumn-winter period..
The pot with zamiokulkas located in the back of the room needs to be rearranged closer to the window, when this is not possible, the culture is provided with additional illumination.
The owner of an ornamental plant, who complains that zamiokulkas does not give new shoots, should pay attention to the location of the pot and the quality of the soil in it. Although the plant is not fast-growing, the slowdown in young foliage is often attributed to a nutrient-poor substrate or the need to transplant a green pet. In this case, the root system takes up the entire volume of the pot, leaving no room for soil. Because of this, the flower suffers, the leaves of the zamiokulkas turn yellow, growth stops, and the existing greenery withers.
To remedy the situation, a pot of the proper size is selected for an ornamental culture, a transplant or feeding of zamiokulkas with a complex composition is carried out.
Zamiokulkas has shriveled stem
What most growers take for the stem of the zamiokulkas and its pointed lanceolate leaves is actually a leaf of a complex shape. If the thickened petioles lose their elasticity, and the leaves of the zamiokulkas turn yellow, the reason may lie in a violation of watering rules.
In nature, the plant encounters drought and accumulates moisture in powerful succulent leaves to maintain life. When the zamioculcas chronically receives less water, that is, watering is rare and superficial, this threatens with yellowing and wilting of all the aboveground parts. A similar situation is observed after the flooding of the soil, which led to damage to the root system..
Asking: “What to do, and why does the zamioculcas turn yellow?”.
If the stem of the zamiokulkas has shriveled due to overflow:
- the flower is taken out of the pot;
- carefully remove the soil and wash the roots;
- damaged areas are removed with a clean, sharp knife;
- slices on healthy tissue are sprinkled with charcoal powder and dried.
Having found signs of rot or fungal infection, the indoor plant lover should not be limited to charcoal treatment. In this case, it is worth resorting to fungicides, which will destroy one of the causes of the problem, protect the roots and tubers in the future..
Planting zamiokulkas is carried out in pots, a little more than the volume of a healthy root system. The substrate should be loose, permeable to air and moisture. It is important that irrigation water does not accumulate in the soil, therefore powerful drainage is made in the pot, and sand, perlite or vermiculite and charcoal are added to the soil..
When the leaves of zamiokulkas turn yellow after transplanting, this may indicate an incorrect selection of the substrate, which turned out to be too dense.
A similar situation awaits a grower if, in an effort to feed the plant, he incorrectly selected the concentration of active substances. Unable to cope with excess nutrition, Zamiokulkas experiences discomfort and weakens. That is why zamioculcas turns yellow, but what to do in such a situation? Unfortunately, even here you cannot do without transplanting the bush into new soil and washing the roots..
What to do if the leaves of zamiokulkas turn yellow, and then become covered with dark spots and dry quickly. Such symptoms indicate a too low temperature of the plant’s maintenance and excessive watering. Most often this happens when the season changes, when the grower did not have time to adjust the care. If the green pet’s malaise is noticed in time, it will be enough to set up watering or transfer the pot to heat.
If the leaves of zamiokulkas turn yellow, the flower can signal a pest attack.
A plant that is brought outdoors in summer is at risk of aphid infestation, which sticks to young shoots and the back of the foliage. The insect brings the greatest harm to immature plants..
Therefore, after bringing the pot into the room, it is better to arrange a weekly quarantine for the zamiokulkas, and to identify pests, treat the greens with an insecticide.
In addition to aphids, culture is threatened by:
- spider mites that quickly spread in dry indoor air;
- scale insects falling on zamiokulkas from the street or neighboring plants;
- thrips and mealybugs.
It is not enough to fight spider mites with systemic acaricides. Chemicals will only give a temporary effect if you do not take care of the yellowed zamiokulkas at home..
Systemic insecticides are used against scale insects, thrips and worms, and in relation to the last two pests it will be necessary to carry out not one, but several treatments.
To avoid an unpleasant spectacle for the grower, when the zamioculcas turns yellow, the leaves of the flower wither and fall off, you can provide the plant with the optimal temperature of maintenance, lighting, watering and feeding. We must not forget about the timely transplantation of decorative culture and careful attention to the selection of the substrate..
