Why geranium leaves turn yellow, treatment of geranium

It is safe to say that every person has houseplants in the house, but the inhabitants of our country have a special love for geranium.

Major Geranium Pests

Geranium, like any other plant, has many enemies. Various diseases and pests can cause serious damage to room geraniums. The most common pests are:

• aphid;
• various caterpillars;
• ants;
• rot;

The infection spreads quickly throughout the plant, and if measures are not taken in time to eliminate it, then the flower can be lost.

How to understand that geranium needs treatment

Even the most experienced and caring owners, it is possible the emergence of diseases of geraniums. The reason for this may be:

• a small pot, because of which the root system of a plant cannot develop normally;
• the absence or lack of drainage in the tank;
• lack of sunlight and constant drafts;
• excessive moisture;
• A surplus of fertilizers with nitrogen, due to which the green mass develops rapidly and damages flowering;
• too little potassium and phosphorus in the soil.

Symptoms of geranium disease can be:

• The appearance of spots on the leaves. This can be caused by bacteria and fungi. Also, the appearance of thrips on pelargonium.
• "Rust" on the leaves of the plant. If you find similar spots on the leaves of a flower, it means that you have got a fungus.
• Rotting stem. The reason is bacteria. There is a chance to lose the plant if you do not do the treatment.
• The plant is covered with gray spots and not aesthetic bloom. In this case, the geranium picked up gray mold.
• Leaf bleaching. This suggests that you have got an aphid on geraniums, and the earlier you decide to take it out, the more chances you have to save the plant.

Root rot and how to eliminate it

Root rot begins due to fungi that inhabit the soil. Most often, it affects geranium stems, which are located at ground level or near the surface. Due to the appearance of such a fungus, the stem of a flower simply falls.

It would be better to throw out infected geraniums or try to cut the affected part of the plant with a sharp and clean knife. After using the tool, it must be well sanitized. So that you do not have root rot, you do not need to pour much geranium, improve soil drainage, add a mixture of vermiculite, peat moss or perlite. Between colors it is necessary to observe an interval.

What to do if all the leaves are stained

The appearance of spots on the leaves indicates the defeat of the flower by an insect pest or harmful fungus. It is better not to delay and immediately take measures to eliminate the threat, because the disease can go to neighboring plants.

Tomato Spots

If geranium is stunted and there is a ring spot on it, well inspect it for the presence of "tomato spots". Most likely, these spots will be slightly faded. Having found them, inspect the aerial parts of the plant. If there are specific indentations, then the flower will have to be thrown out. Fighting tomato stains will not bring success, and vain attempts to help the plant will lead to the transition of bacteria to neighboring flowers.

Spots like bubbles

The appearance on the leaves of geranium spots in the form of bubbles, due to the influence of harmful fungi - Alternaria and Cercospora. Alterinariasis and chalcosporia affect the appearance of hollow brown formations on the leaves. Such spots are vaguely reminiscent of a rash and can lead to leaf fall. After some time, spores appear on the site of the infected area, and then dark, slightly elevated places.

Rusty spots

Rusty spots on geraniums result from the activation of fungi. Rust begins to appear yellow spots on the top of the sheet. The effect of rust is spread through sucking insects, contaminated soil, or through other already infected plants.

To combat the rust stains, the first thing is to isolate the infected flower. If the infection did not manage to disperse strongly in the plant, remove only the affected parts. In the case of a running form, treat the plant with colloidal sulfur. Near the standing plants also need to handle "Kratan" or "Akreksom."

Gray Rot Houseplant

If you find that your geranium dies from gray rot, the question: "What to do?" should arise first.

Gray rot on the geranium is manifested in the form of brown spots. The leaves that are closer to the soil suffer the most.

Gray rot occurs due to:

• transmission by airborne droplets;
• during soil replacement;
• due to the increased humidity of the premises and the soil;
• poor ventilation and abundant watering.

Finding the presence of gray rot on their flowers, You must immediately remove the infected areas and treat the plant with a fungicide. Thus, having understood the conditions in which pelargonium will feel best, you will be able to prevent the negative influence of any pests who dare attach to your flower.
