What causes leaves to turn yellow?
Diseases and Pest Attacks
Damage to the plant by a fungal or bacterial disease leads to yellowing and leaf fall. Attacks by some pests cause plants to turn yellow.
- The occupation of a plant by a spider mite is a common cause of plant leaves turning yellow with brown spots. The first symptom is the appearance of thin white cobweb veins, followed by yellow spots on the leaves. Spider mites are a common cause of yellow leaves. It is especially dangerous for roses and will be extremely difficult to get rid of. The disease first manifests itself as a whitish bloom on the leaves and the formation of barely noticeable cobwebs, then house plant leaves turning yellow, and they begin to gradually die off. The tick is able to completely destroy the plant very quickly.
- Aphids and scale insects feed on sap from the leaves, because of them, clearly visible brown plaques appear on the leaf surface. Pests live in large colonies, so it is necessary to carry out complex treatment.
- Fungal diseases can also cause the yellowing of the green part of the plant. A common cause of yellowing is fungal infections. They appear as yellowish-brown spots on the leaves, the plates wither, dry, and fall off, and the fungus moves higher to the next leaf. This disease often affects geraniums. The fungus is well preserved in the soil, therefore, not only medical treatment is necessary, but also soil replacement.
Why are my plant leaves turning yellow? Due to these and other diseases, the new growth leaves turning yellow and can quickly lose leaves, which poses a serious threat to it. It is necessary to take a measure already when the first symptoms of the disease are detected.
What Are Plants Missing?
Why do plant leaves turn yellow? Green plants can not only be deficient in nutrients but also become victims of insect pests. Let’s consider all the possible reasons due to which the leaves change color.
- Potassium deficiency. The edges and tips of the leaves turn yellow, while the veins do not change color. Method of struggle: Place citrus peels at the base of the plant and add nutritious soil prepared from compost. Feeding with potassium sulfate will also help.
- Lack of nitrogen. The tips and veins of the leaves turn yellow. Method of struggle: mulch the soil in the pot with compost or coffee grounds.
- Lack of calcium. The leaves are deformed, become irregular, curl and look withered. This is most often observed when the soil in the pot is too acidic or, conversely, alkaline. Add gypsum to improve alkaline soil and lime for supersaturated soil.
- Lack of zinc. The leaves seem to fade and discolor, while the veins bulge out and become more noticeable. Method of struggle: feed the plant with zinc sulfate or spray with an extract from algae. A lot of zinc is found, for example, in kelp algae.
- Iron deficiency. The leaves turn yellow and decrease in size, the veins remain green and protrude sharply above the surface. Most often, iron deficiency occurs on alkaline soil. Method of struggle: feed the plant with iron sulfate or stick a rusty nail into the pot.
- Lack of magnesium. A white border appears around the veins along the contour. Method of struggle: apply fertilizers rich in magnesium, or magnesium sulfate and lime.
Treatment of a Plant with Yellowed Leaves
Treatment for the bottom leaves turning yellow in a home plant depends on the underlying cause. If pests or symptoms of a disease are found, the plant must be separated from the rest, in parallel with the treatment of the “patient” to carry out prophylaxis for the rest of the flowers. And in the case of a fungal disease, you will need a flower transplant and soil disinfection. Treatment is carried out with fungicides according to the instructions specified by the manufacturer. It is much easier to eliminate the yellowing of leaves caused by disturbed care. If there is a lack of trace elements, increase the dose or frequency of mineral fertilizers: in winter, it is enough to feed once a month, in summer – every 10-14 days. Eliminate dry air by frequent spraying or a drip pan with wet moss or expanded clay, lack of lighting – with a fit-lamp. Determine the amount and frequency of watering empirically. Touch the topsoil before watering. Water only after the top layer is dry.
Prevention of Yellow Leaves on the Plant
Dealing with the consequences is always more difficult than initially taking care of the safety of the flowers. Can yellow leaves turn green again? Use the advice of flower growers to prevent the yellowing of the leaves of indoor plants.
- Pest prevention consists of maintaining the correct air humidity. Avoid shade and sanitary pruning to avoid thickening the shoots.
- Inspect the plants a couple of times a week, every time you water. Removing pests that have just settled on a flower is much faster and easier than removing a colony.
- Prevention of fungal diseases consists of the correct amount of watering, regular ventilation of the room, as well as feeding the plants to maintain strong health.
- Study the agricultural techniques of each plant grown at home, observe the conditions of maintenance and proper care for the flowers.
Another important fact about all leaves turning yellow during flowering. Before taking any action to save flowers, make sure the yellow leaves on houseplants are not natural. Over time, the leaf plate grows old, turns yellow, and falls off, a young leaf comes in its place.
After studying the above rules, remember: before starting to save the situation, carefully study the life cycle of a particular plant. It may happen that the yellowing of the leaves is its normal and traditional stage of development (cyclamen), in which case there is no need to do anything.
