Causes and Solutions for Dry, Yellowing Areca Palm Leaves
Because the areca palm is a foliage plant, the thing most feared when growing areca palms is yellowing and drying leaves, which not only greatly affects the appearance and beauty of the whole plant, but more importantly, the state of the leaves is also a very strong indicator of the areca palm's growth condition. Once phenomena such as yellowing and drying appear, it means the areca palm's life may be in danger.
What to Do When Areca Palm Leaves Dry Out
1. Areca palm leaf tips dry and scorch——air too dry
Areca palms like relatively high air humidity. When growing them, if the air is relatively dry, the leaf tips are prone to drying and scorching, and scorched edges appear.
During the growing period, the areca palm needs to be kept in relatively high air humidity. The leaves and the surrounding area need to be sprayed with water every day, which can raise the air humidity. But note that watering should be stopped when the plant is dormant.
2. Areca palm leaf tips dry and scorch——sunlight too strong
When growing areca palms, suitable light needs to be maintained. In summer the sunlight is relatively strong, so it is best to grow the areca palm in a semi-shaded environment. Too much light or direct strong light will cause the areca palm's leaves to develop scorched tips or scorched edges. So in summer it is best to avoid direct strong light on the areca palm, place it in a semi-shaded spot, and pay attention to shading.
3. Areca palm leaf tips dry and scorch——potting soil too dry
Watering too little, causing the potting soil to become too dry, is also a cause of dry, scorched areca palm leaf tips. During the areca palm's growing period, sufficient water must be guaranteed. If the potting soil is dry for a long time, the plant cannot absorb enough water, causing its leaf tips to dry and scorch, so it must be watered in the right amount.
4. Areca palm leaf tips dry and scorch——potting soil too wet
Relatively speaking, the areca palm's potting soil also must not be too wet. Once too much watering occurs during cultivation and the potting soil becomes too wet with standing water, it will hinder the roots' respiration, cause root rot, and leave the plant internally short of water, which in turn makes its leaf tips dry and scorch.
5. Areca palm leaf tips dry and scorch——fertilizer too concentrated
Fertilizer that is too concentrated mainly causes the problem of root burn. Problems with the roots cause the plant to lose water. In milder cases it causes dry, scorched leaf tips; in severe cases it causes root rot. So when fertilizing the areca palm, pay attention to the concentration, and light fertilizer is best.
In addition, if the areca palm is grown indoors in winter, it is best to keep it away from air conditioners and heaters so the plant does not get scorched.
Causes and Solutions for Yellowing Areca Palm Leaves
1. Unsuitable soil
Indoor potted areca palms should be given slightly acidic soil. If the soil is not acidic enough, it will affect the absorption function of the areca palm's root system, causing the leaves to turn yellow.
Areca palms are suited to sandy loam soil. If the potting soil is excessively sticky and heavy, part of the root system will rot at the tips first, then the leaves will begin to turn yellow, and the plant will grow poorly or even die.
2. Improper transplanting
Transplanting into a pot is an important step in home cultivation of areca palms, and improper handling can cause the plant's leaves to turn yellow. When potting, part of the outer root system needs to be removed, but the outer roots are the main roots for root respiration. If they are damaged by improper handling, the plant's nutrient supply fails, and the plant will gradually wither and die. The sign of death is yellowing, drooping leaves.
3. Overwatering
Areca palms are relatively tall, and the nutrients the leaves need must be transported by the roots. With proper watering, the roots can absorb quickly and keep the leaves emerald green, but if the potting soil is too wet, it will affect the roots' respiration and the roots' water absorption, directly causing the leaves to turn yellow.
4. Underwatering
Too much watering is no good, and too little watering is no good either. During the areca palm's growing period, sufficient water must be supplied. When the potting soil stays dry for a long time, because the plant's growth cannot get the sufficient water it needs, the leaves will begin to turn yellow and wither.
5. Humidity too low
The areca palm's growth requires relatively high air humidity. When the air is too dry, the leaves will slowly begin to turn yellow. Throughout the growing period, water should be sprayed on the leaf surfaces and the surrounding environment 3~4 times a day to raise the air humidity. But after dormancy (after the start of winter), watering should be stopped.
6. Temperature too low
Areca palms like warmth, and in winter good insulation and freeze protection work must be done. Generally around 10°C allows relatively safe overwintering. If the temperature is too low, the plant suffers cold damage, the leaves turn yellow, the leaf tips dry up, and the roots are damaged, affecting the next year's growth.
7. Sunlight too strong
The areca palm's growth requires sufficient sunlight, but from May to September it needs appropriate shading. During this period, too strong light easily causes the plant's leaves to be scorched, which is what we commonly call sunscald; yellow spots appear on the leaves, and they scorch and turn yellow. As time goes on, the whole plant will wilt. So in summer the plant should be kept under a shade canopy or under a large tree to avoid direct sunlight.
8. Pest infestation
Spider mites, scale insects and the like are relatively common pests of areca palms. When spider mites or scale insects grow on the areca palm's leaves, the pests damage the plant, and the areca palm's leaves will begin to turn yellow. If measures such as pesticide spraying are not carried out, the areca palm will slowly die.
Solutions for Drooping Areca Palm Leaves
1. Supplement light and water
Move the areca palm to a place with ideal light for care. If there is continuous rainy weather, artificial light can be added to ensure sufficient sunlight.
Water promptly; after watering, drooping areca palm leaves can return to their original state.
2. Raise the temperature and control fertilizer
Move the areca palm to a warm place, and in winter the indoor temperature can be appropriately increased.
Control the amount of nitrogen fertilizer applied, and appropriately increase the application of phosphorus and potassium fertilizer to ensure sufficient nutrients.
The Habits of the Areca Palm
The areca palm is a tropical plant and likes a warm, humid, semi-shaded environment. Its cold tolerance is relatively poor; below 20°C the leaves show yellowing. In winter, overwintering safely is possible when the temperature reaches above 10°C; at 5°C it will freeze to death.
Areca palm seedlings grow slowly, and after they grow into young plants they grow rapidly. It is suited to loose, well-drained, fertile soil. Its branches and leaves are dense, it stays evergreen all year round, and it has strong shade tolerance.
Areca palms cultivated outdoors in northern China are generally brought indoors from late September to early October and must be placed in a spot with sufficient sunlight. During the overwintering period, the room temperature should be 23-25°C during the day and maintained at 15°C at night, and must at least stay above 8°C, otherwise cold damage will occur, causing death in winter and spring. During the overwintering period, also pay attention to often wiping the leaf surfaces or spraying a small amount of water on the leaf surfaces to keep the leaves clean.
There are many causes that can make areca palm leaves turn yellow and dry out, and we need to rule them out one by one so that we can treat the areca palm in a targeted way. In addition, drooping leaves are also a relatively common phenomenon in the process of growing areca palms, and growers also need to pay close attention to it.
