Yucca - leaves turn yellow and dry, what to do
Content:
Yucca (lat. Yucca) is an ornamental plant that can often be found in houses and apartments. The flower is part of the Agave family. The plant is distinguished by weak shoots and large caps of green leaves. However, they can sometimes turn yellow and dry out. The flower loses its decorative effect. Why the leaves of the yucca flower turn yellow and dry, what to do in this case and how to save a houseplant, will be described in this material.
Yucca leaves dry and turn yellow - what could be the reasons
There are many reasons why yucca leaves turn yellow. In most cases, the process occurs as a result of improper flower care. If you do not take the necessary measures in time, you can lose the plant.
Yucca leaves can turn yellow for various reasons.
The main reasons for the yellowing of the foliage in yucca are the following:
- physiology,
- lack of nutrients,
- improper watering,
- unsuitable air temperature,
- violation of the light regime,
- damage by harmful insects,
- various diseases.
Diseases
Often the reason why the tips of the leaves dry in yucca is the presence of various plant diseases. Improper and excessive watering, hypothermia of the flower often cause the development of fungal diseases. Unfortunately, they are quite difficult to spot. The main sign is considered to be a change in the appearance of sheet plates for no apparent reason.
To save the plant, you need to stop watering and treat the yucca with special fungicidal agents. You may need to transplant the culture into another pot.
Yellow leaves occur in various diseases
Pests
Violation of the decorative effect of the plant and problems with leaves can occur when the flower is affected by various pests. The following are considered the main ones:
- shield,
- aphid,
- spider mite.
These are pests that suck out all the juices from the flower. As a result, the palm tree lacks nutrients, the tips of the leaves dry out on the yucca, they curl and fall off. Improper watering, unsuitable air temperature, and reduced plant immunity can provoke the appearance of parasites.
Pest control should be started immediately after detection. Otherwise, there is a risk of losing the entire plant. Damaged leaves are removed, insects are removed by hand or using a soapy solution.
However, in most cases, it is easier and faster to get rid of parasites by using specialty chemicals. You can use tools such as Fitoverm, Aktara, Aktellik. The solution must be made according to the instructions.
Irrigation of the flower is carried out when the soil in the pot dries at least half. Watering is carried out with settled warm water, from below under the root.
High humidity can cause leaf rot
Cold liquid provokes decay of the roots or base of the trunk. Such a plant can only be saved by transplanting it into another soil.
Air temperature
The ambient temperature for yucca is just as important as proper watering. The wrong temperature regime affects the state of the leaves - they dry, curl and crumble.
The best temperature for yucca (elephant and other species) is considered to be in the range from 20 to 25 degrees. Under such conditions, the plant develops well and does not get sick.
A sharp change in indicators, constant drafts, cold or heat lead to the fact that the culture begins to hurt and quickly dies. Therefore, it is important to provide the yucca with the most suitable conditions for growth and development.
Decay of roots
Decay of the root system occurs due to the constant waterlogging of the soil. In winter, the flower has a dormant period, so watering should be minimal and only with warm water.
With frequent irrigation with cold liquid at low temperatures, the roots begin to freeze, get sick and gradually die off.
Yucca (garden and home) accumulates moisture in the trunk, therefore, with its large volume, the root system begins to rot, the leaves curl, turn yellow and fall off.
The dangerous thing is that it will not be possible to immediately detect root rot. The first sign is the darkening of the base of the leaves. Unfortunately, it is not always possible to save the plant.
If the signs of rot are minimal, then the flower is removed from the pot, the roots are treated with antifungal drugs and transplanted into a new container.
The leaves can turn yellow at the wrong temperature
It is important to normalize the watering regime and follow it exactly in the future.
Other possible problems
The yellowing of the foliage in yucca can occur for natural reasons. Over time, the leaves age, lose their elasticity and strength, and change color. This is a normal aging process. The lower leaves wither, the palm tree cannot get rid of them, so they continue to hang on the stem. Such plates can be easily removed by yourself. Over time, from the remnants of the leaves, a trunk is formed, very similar to a palm tree.
Another reason for the change in the state of the leaves in yucca is a lack of nutrients. A flower during the growing season requires various trace elements for normal development and growth. The lack of the necessary substances also arises if the flower grows in the same soil for a long time. In this case, the root system has already absorbed all the elements from the ground, and new ones are not coming.
Lower leaves may turn yellow for physiological reasons
It is important to determine what exactly the yucca is missing. In the spring, you can transplant the flower into fresh soil. The lack of certain substances can be determined by their appearance:
- Small young leaves of a yellow tint - a lack of nitrogen.
- Mature leaves located in the middle turn yellow - there is little iron.
- The presence of dark streaks on the leaf - there is not enough magnesium.
- Yellow leaf plates with dark spots - little phosphorus.
Suitable preparations can be obtained from specialized stores. Dilute the funds according to the instructions.
The light regime is also important for yucca. The flower needs lighting up to 12 hours a day. With a lack of light, the culture stretches, the leaf plates lose their brightness, become thin, gradually dry out and fall off.
However, it is worth remembering that direct sunlight is also dangerous for the flower. The appearance of burns on the sheet plates is not excluded. In these places, a violation of vital processes occurs, as a result, the leaf does not receive the necessary nutrition, gradually turns yellow and dries up. The plant should be provided with a bright place, protected from direct sunlight.
If not properly cared for, the plant may die.
What to do if yucca palm leaves turn yellow and dry leaves? To revive a flower, you should try to find out the exact cause of the problem with the leaves. If this is rather difficult, then it is better to transplant the plant into a new pot with nutritious soil. When signs of pest infestation appear, the culture is treated with special means. It is important to provide the yucca with proper care - watering, temperature, lighting, feeding. The leaf blades are periodically checked for the possible presence of parasites and diseases.
Yucca is an unpretentious flower and, if you follow the rules, will not cause trouble. Even a novice florist can do a great job with it. When the first signs of flower disease appear, it is recommended to try to determine the cause and eliminate it.
