At room geraniums the leaves turn red and dry: why this happens, the main reasons, prevention, proper care

Geranium is beautiful in that it can be grown at home, both indoor and in the summer on the street or in its garden plots. Even a novice grower will not be difficult to care for this flower, since he does not put forward special requirements. The percentage of cases when the plant does not take root well is very small, so feel free to replenish your flower garden with geraniums as well.

But still, like any plant, geraniums can be attacked by pests and diseases. And we perfectly understand how it feels when your pets take on an unhealthy look. One of the signs of unhealthy geraniums are reddened leaves. We will begin to understand why the saturated green leaves change their color to reddish. An unequivocal answer to this question is very difficult to give even to experienced gardeners. We list the possible errors in the care of geraniums.

Waterlogging

ATTENTION: On our vast planet there are more than 400 types of geraniums that are found in various parts of the Earth. In Russia, about 40 species are the most popular.

90% of the plants of the Geraniev family are drought-resistant, so they do not need abundant and frequent watering. In this case, redness may indicate root rot, the causative agent of which is the fungus. He lives on the roots. But when the plant is healthy and has good immunity, then infections are not afraid of him. Overmoistening weakens the immunity of geraniums, thereby making it vulnerable.

The first external sign of this disease is the dark red stripes on the lower leaves. What does this lead to? A root infected with a fungus does not adequately supply the plant with nutrients, which is fraught with growth retardation and wilting (what to do if geranium in a pot withers and why this happens, read here). In this situation, you need to reduce the abundance and frequency of watering, and the growth and development of the flower will return to normal.

Temperature violation

Temperatures below 18 degrees can cause the geranium to freeze.. What if, as a result, the leaves turn red at the edges and dry, and then completely fall off, as if in autumn?

To deal with this problem is very simple - do not allow too cold temperatures for the flower. Then geranium will delight you with its rich color, even in winter.

We identified two main causes of reddening of the leaves along the edges. Further in the article, we will consider why pigmentation appears on the leaflets.

Nutrient deficiency

Problems with the nutrition of the flower can occur due to the electrical conductivity of the soil or a high pH level. Outwardly, signs of a lack of any elements will appear only after 2-6 weeks. What kind of food a flower will receive, the influence of quality, quality and method of watering, as well as the shape of the pot.

IMPORTANT: Nitrogen starvation immediately affects the lower leaves, red pigmentation appears on them, and the edges curl down. If the situation is not corrected in time, this disease will go to the trunk and cause its lignification.

The lack of phosphorus will become noticeable first on the back of the leaf plate (they will be covered with red spots), and then it will go to the upper part. Over time, the spots on the leaves of the geranium will turn brown, and the leaves will become dry.

Zinc deficiency affects the shape of the leaves, pink and orange pigmentation appears on them. How to deal with this? Start feeding geranium with fertilizers. But do not overdo it, otherwise get the opposite result. In this difficult matter, it is important to find a middle ground.

Sunburn

Here, not only the barrel can suffer, but the trunk will turn red too. Although many sources indicate that geranium can easily tolerate direct sunlight, this information is not entirely correct.

Young leaves can survive the intense lighting, but the old ones will not like it, and they will begin to blush and fall away. All you can do is move the flower pot to another place where there will be not so much light. Of course, this will not save the affected leaves, but it will not let the rest fall under the negative influence of the sun.

Redness on the back

Sometimes it happens that the leaves turned red on the underside and the aphid, which damages the structure of the leaf, can become the reason for this. Over time, the leaves frown and fall. Aphids are removed from plants mechanically or by spraying with insecticides.

To summarize the restoration of geranium after illness. You need:

1. Check soil for pH. If necessary, reduce soil acidity.
2. Refuse to use filtered water for irrigation. The filter does not leave in the water any trace elements so necessary to the plant.
3. To analyze the conditions of the geranium and adjust them to normal (lighting, temperature and humidity, watering). But try to make it so that the plant does not get stress with a sharp change in conditions.
4. Seek help with purchased complex fertilizers. Always read the instructions and use the dosage before use. Everything is fine back to normal.

Preventive measures

Any trouble is easier to prevent than to fix. The same applies to plant diseases. Choose a healthy planting material, use pots of the appropriate size (the roots should not be crowded, but not too spacious, otherwise all growth will go to the roots, not to flowering), always when buying! Check the cuttings for the presence of all kinds of diseases. Before planting, it will not be superfluous to treat the prepared cuttings with a fungicide.

Yellowing

This signals the following:

• There is little space in the pot for the roots. Lack of space inhibits the development of geraniums and leads to yellowing and further dropping of leaves.
• Cool air or drafts. Most often, this affects the flowers on the windowsill. Some gardeners prefer to winter their pets. To do this, you need to cut the leaves yourself, reduce the frequency of watering and lower the air temperature to about 14 degrees above zero.
• Watering is rare, but very plentiful. It is better to water more often, but in small portions, and only when the top layer of the earth becomes dry.
• Excess fertilizer, especially nitrogen. In winter, geraniums are best fed as little as possible.

Details about why geraniums turn yellow and dry around the edges and how to deal with it, read here, and from this article you will learn how to feed and water geraniums to avoid yellowing of foliage.

Lack of flowering

1. The cache-pot is chosen too large, therefore all forces are directed to the growth of roots.
2. The geranium has a dormant period, most often this happens in the fall. This is the norm, and you should not worry about it at all. Just wait until spring.
3. You did not provide the flower with a winter holiday. And therefore, the plant has not accumulated enough strength for lush and rapid flowering.
4. Geranium is not provided with favorable conditions for growth and development, which were described above.

And in conclusion of the foregoing, I want to recall that any plant, despite all its unpretentiousness, requires decent care for it. Therefore, always try to get as much information as possible about the content of a flower. And I hope that our articles will become your permanent assistant and adviser in this.
