Lack of drainage layer

Leaves may turn yellow due to the lack of a drainage layer. Geranium does not like swampy soil, it is worth taking care of drainage even at the stage of flower transplantation. In addition to yellow leaves, the flower may stop blooming.

Cramped pot

The small volume of the flower pot does not allow the root system to get enough nutrients from the substrate. As a result, it stops growing and begins to wither.

Errors in care during the dormant period of the flower

In winter, it is worth changing the care of the plant, since it is in a dormant period. The flower is not placed in a draft, near radiators and other heating devices. Reduce the number of irrigations, as they lead to waterlogging of the soil.

Lack or excess of feeding

Nitrogen fertilizers are most often applied in the spring so that the flower gains a green mass. With constant fertilization with this component, the plant will develop late flowering, and the leaves also turn yellow. Top dressing is useful only in a reasonable amount and at a certain period.

there should be a lot of free space around and an influx of fresh air;
the flower is photophilous, therefore good illumination is important;
drafts are unacceptable.

High air humidity

Ampel plants are kept under certain conditions. Comfortable air humidity for geraniums is 50-60%. Increasing and decreasing this indicator can lead to the fact that the flower will begin to wither.

Transplant errors

When transplanting, proceed with caution. It is not recommended to destroy the earthen lump, since in this case the roots are damaged. The plant is preliminarily watered abundantly, and only after a couple of hours they begin to transplant, carefully washing off the substrate from the roots.

The transplant soil should be well-drained, moderately loose. Withstand neutral acidity, slightly acidified environment is acceptable. Prepare the soil on their own from the following components:

river sand;
turf land;
peat substrate;
humus.

All ingredients are taken in equal proportions. Do not forget to regularly feed the plant so that the substrate is nutritious. Otherwise, the flower may begin to wilt. Potassium is required for active growth, phosphorus for flowering, and nitrogen for green mass.

Transplant is an important step in care
