Why do geranium leaves turn yellow: what to do?
Geranium is loved for its unpretentiousness combined with bright beauty. But even with the most undemanding plants, problems arise, as with any living organism. Geranium leaves may turn yellow, dry and curl. We tell why this is happening and what measures to take!
Too rare or excessive watering leads to the same consequence: geranium gradually dies. When there is too much moisture, the leaves turn yellow and become softer, and eventually rot and fungus develop. But from dryness, the plates do not soften, but rather dry out from the edges.
When overflowing, let the substrate dry out, and in advanced situations - transplant geraniums into a new pot with new loose soil. In the second case - resume watering in normal mode, and soon the flower will return to normal.
Geranium does not tolerate swampy soil, and this applies not only to indoor, but also garden. Necessarily need good drainage and fairly loose soil that allows air to pass through. When this is not there, geranium not only turns yellow, but also blooms poorly.
All plants need nitrogen to build green mass and form a neat bush, which geraniums are good for. But if there is too much nitrogen, the geranium also gradually turns yellow. The easiest way is to transplant a flower or at least rinse the soil with running water.
Lack of space
This problem is characteristic of indoor seedlings, which live in flowerpots. It grows quite quickly, and it certainly needs a pot in size. In a tight container, the roots do not receive the normal amount of nutrients, which is why leaves begin to turn yellow in geraniums.
If you bring geraniums into the room for the winter, it is very important to ensure the correct conditions for it. Do not put pots on the battery and avoid high temperatures in general. Be sure to take care of protection against drafts and do not overfill the flower, otherwise the leaves will turn yellow and fall off.
If the leaves of the geranium turn yellow with round spots that darken over time and pass to the stems, it looks like a fungus. There are different types of fungal diseases, but the treatment is always the same. Remove damaged fragments, sprinkle all sections with charcoal, treat geranium with fungicides and adjust the watering regime.
Verticillin wilt is a viral disease that can affect geraniums. Because of it, the leaves turn yellow, but first the yellowness appears on the lower part, and not, as always, from the edges. Gradually, it spreads over the entire leaf, and then passes to the stem until the plant dies completely.
Pests and parasites
Geranium leaves may turn yellow due to parasites or insects, and it is important to consider other symptoms correctly. For example, a sticky coating leaves aphids, brown tubercles - scale insects, and a whitish web - a tick.
Whiteflies and caterpillars eat leaves and suck out nutrients from them, which is also fraught with yellowness. In any case, the flowers should be treated as soon as possible with insecticides, and in the future, do not neglect the planned treatment from pests.
Geranium leaves turn yellow at the edges
Most often, geranium leaves turn yellow around the edges due to improper care. If the natural yellowness associated with aging begins from the bottom up, then in this case the leaves are desired from the crown. Adjust the watering mode, check the temperature in the room and make sure that the flower has enough light.
If the leaves turn yellow in the summer without any other external symptoms, try simply watering the geranium more often. And if they react so much to a transplant or moving from street to room - it's just stress. Give the geranium a little time to acclimatize, and it will recover on its own.
Leaves of geranium turn yellow spots.
If the leaves of the geranium turn yellow with uneven spots, this most often indicates an infection or virus. Typically, over time, such plates turn brown and die, and the whole process is accompanied by other symptoms. For treatment, fungicides or special antibiotics are used.
The most dangerous enemy is a viral mosaic that is impossible to get rid of. If the yellow spots add up to a bizarre mosaic pattern - most likely, this is the case. Then the geranium must be immediately isolated and destroyed as soon as possible, until the disease spreads to neighboring flowers.
What to do so that the leaves of geranium do not turn yellow?
Choose the right place for planting, watch for lighting and the absence of drafts. Set the watering regime, control the dryness of the top layer of the soil and apply fertilizers on time according to the schedule.
Indoor geraniums should grow in size in a pot, and for the winter she needs coolness. Examine flowers regularly for symptoms of diseases and pests to take action in time!
