Homeland palm tree is a small Australian island of Lord Howe, located in the Tasman Sea. The most common with us are the Foster and Belmore hovey. They are unpretentious in care and have gained popularity with designers.
However, this plant often presents unpleasant surprises to the owners: the leaves of the Hovei dry, and if they do not take proper measures, it will die. Symptoms of the disease may be different. What is the reason for the sudden "ailments" of Hovei, how to avoid them when growing palm trees - let's try to figure it out.
Did you know? Experts believe that this palm tree fills the office space with positive energy, increases the charge of optimism and increases efficiency.
Yellow leaves
The Australian palm is considered an unpretentious plant. However, if you do not comply with the regime of humidity and temperature, it suddenly begins to turn yellow crown.
Howei Foster grows in the subtropical zone. However, when creating artificial conditions of subtropics in your room, you can ruin a plant: its leaves begin to turn yellow, hovey does not grow, begins to quickly fade and perishes. 
The yellow crown is a wake-up call, which indicates a change in the comfortable living environment. Owners of the flower, trying to warm it, put Hovey closer to the battery or other heat sources. Loss of moisture leads to yellowing crown.
Experienced flower growers sprayed the plant from a spray bottle, put water containers next to it, if the budget allows it, buy a decorative fountain, and the flower regains its green color. Humidity in the room should be 60-65%.
To create a tropical corner in the house will help other types of palm trees, such as Hamedorea or date palm.
Dry ends of leaves
Palma sensitively responds to the cleanliness of the air in the room. She does not tolerate tobacco smoke. The green flower crown begins to dry out. 
Causes of drying maybe a few:
- The tips of the leaves of the subtropical palm begin to dry when the temperature of the air in the room drops below 18 degrees Celsius.
- Chlorosis (drying) of the fan crown may begin due to a lack of phosphorus fertilizers in the soil or an excess of fluorine-containing preparations in the universal nutritional supplement that is offered in stores. Ask the seller about the compatibility of the fertilizer with palm plants.
- And the last reason for drying is excessive watering. In winter, it is recommended to water the palm tree only when the top layer of soil dries out by 1.5-2 centimeters.
Causes of Hovei blanching
The fan crown of a palm tree loses its bright green color and begins to turn pale only when it stands on draft. Under natural conditions, the wind blows at the same humidity and temperature.
Important! Draft in offices reflected on the color of the leaves. The palm tree from the temperature drop disrupts the process of photosynthesis, which entails the loss of immunity to disease.
When blanching leaves, the plant must be moved away from drafts.
Black dots on the plant
Black dots on the leaves - an alarming symptom for the owners of the plant. Blackening of leaves occurs when there is excessive temperature in the room and insufficient watering of the flower. If the palm tree is not rearranged in time in a cool place and does not increase watering, the plant will die.
The second reason for the appearance of black on the leaves is the other extreme. Many owners literally poured a flower and put Hovey in a cool place in a draft. 
The result is one: the blackening of individual leaves, then the entire crown, which will lead to the death of the plant.
To avoid this, it is necessary to provide a stationary the temperature from 20 to 24 degrees Celsius and humidity 60-65%.
If you like palm trees, yucca, dracaena, nolin, tsiperus similar to them will suit your home decor.
White spots: what to do
Sometimes white spots appear on the leaves of the fan crown of the Hovei. This is the first sign. excess chlorine in water for irrigation. Undistressed tap water affects the development of the phytoplasmic leaf structure and disrupts the natural synthesis of the plant.
Did you know? Industrial chlorine, which does not have an additional electron of natural valence, enters into the intracellular interaction with the atoms of the released ozone and "suppresses" the process of photosynthesis. As a result, the final function of the plant - the release of oxygen - atrophies. White spots on the leaves of Hovei - dead sections of chlorophyll.
In order to avoid the disease, it is necessary to water the palm with separated, and even better, melt water. 
Experienced flower growers freeze nylon bottles with ordinary water in a refrigerating chamber and then use it for watering Hovei.
Why do hovei appear brown spots
Brown spots - the most common disease in unpretentious palm. The first sign - Hovey does not grow, the second - green leaves suddenly begin to acquire brown lacunae.
The main cause of the disease of the plant lies in boron excess in water for irrigation. Boron is not chlorine tap water. You can’t get rid of it so easily, as it is a part of even the most purified drinking water.
Important! Experts recommend lowering the concentration of boron sugar. Half a liter of distilled water put half a teaspoon of sugar. Glucose annihilates excess bromine, and the brown spots gradually (after 4-6 months) will disappear.
