Majesty Palm White Fungus [Causes & How to Fix]

Mealybugs are insects found in moist, warm habitats and are the leading cause of the white fungus on the Majesty Palm. The home remedy for getting rid of mealybugs is to spray rubbing alcohol, but that’s not always the first line of treatment for a Majesty Palm. 

Majesty Palm and Mealybugs

A popular tropical palm known as the Majesty Palm has lovely, long green fronds. The majestic palm is indigenous to Madagascar and may reach around 100 feet.

However, it is becoming more popular as an indoor tree, where stifling its roots limits the plants’ height to around 10 feet. It has several stems covered with tall, arched green fronds.

Although a slow-growing plant, with proper care, it may grow to a height of up to 10 feet, instantly giving your room a jungle feel.

When young and mature, it resembles the equally beautiful kentia palm. However, growing it effectively indoors can be challenging since it needs moist air, solid indirect light, and regular watering.

Even in the sunniest areas, Majesty Palms do not survive well inside. During the summer, they will survive just fine on a patio but quickly decay if taken indoors. They often need a lot of direct sunshine and a lot of water. Stress makes plants far more vulnerable to plant pests like mealybugs.

Mealybugs are wingless insects that generally appear as white cottony masses on plants’ leaves, stems, and fruit. These bugs are common in indoor plants, gardens, and greenhouses. They obtain their food by sticking their lengthy sucking mouthparts, known as stylets, into plants and sucking the sap from the tissue. 

At low infestation levels, the damage is frequently insignificant. Higher populations, however, might damage the plant and result in leaf bending and yellowing.

Honeydew, which makes the plant sticky and promotes the development of sooty molds, is typically present during feeding. A typical greenhouse pest that harms houseplants is mealybugs.

Powdery mildew frequently develops on indoor plants that grow under poor lighting or close quarters. Winter’s shorter days and less intense sunshine may make this condition more common. Remove the plant’s leaves, move them into more light, and, if you can, add artificial lighting.

Use a fungicide indicated for managing powdery mildew on houseplants if the issue persists. The plant-derived fungicide Neem is preferred by many gardeners. No matter what product you pick, thoroughly read and adhere to all label instructions.

What are the White Spots on a Majesty Palm?

Bacteria, viruses, and fungi are mostly the culprits behind the white marks that appear on the Majesty Palm. The plant develops white spots as it grows, but they are more apparent when it is agitated or under attack.

They appear when a plant’s immune system attempts to protect itself from an outside threat. White spots may appear unimportant, but they can spread fast if they affect several different plant sections.

According to one study, there are two different types of white spots on palm leaves: those brought on by bacterial infections and those brought on by fungal infections. Due to the structure of the leaf, it might be challenging to see the spots which usually appear on the lower leaf, far from the oil glands.

Treat with a Fungicide

The palm should be inserted into a hole from the fresh potting soil. Over the roots, apply a fungicide, such as thiophanate-methyl. To make the drench, add one teaspoon to 1 gallon of water. Add dirt over the roots.

Regularly water your palm to maintain soil moisture and promote new growth, but don’t water the plant right to the top of the pot. Root rot fungus is cultivated by overwatering. Digging outside palm trees will get them out of the diseased soil and onto a new spot. Use the same

fungicide on the new and old areas as you would with indoor pots, but avoid planting anything new there.

Sterilize Pots and Equipment

Fill a separate container with fresh, sterilized potting soil. Clean the container with a solution of 1 part bleach to 9 parts water, even if it is brand new. Let it soak for 30 minutes. Before you add the potting soil, could you give it a good rinse with clean water?

Check the pot’s size against the diameter of the palm’s roots; there should be only a little bit more space in the pot than that. Palm plants’ roots decay when given too much room in a planter. The University of  Florida IFAS Extension recommends sterilizing your pruning shears at once to

eliminate any fungal residues. Pruning shears should be soaked for 30 minutes in a solution of 1 part household bleach to 9 parts water.

Tea Tree Oil

White spots may be removed in various methods, but one popular method is mixing tea tree oil and vinegar with water in equal parts. Rinse after using a cotton swab to massage the white spot gently. Repeat this process as necessary. Tea tree oil has been considered a natural antibacterial

since ancient times. When used topically, it likewise has similar qualities. Bacteria and fungi cause white spots; thus, this therapy eliminates them by starting a chemical reaction.

There are multiple ways of getting rid of white spots, but one common technique is combining tea tree oil and vinegar in equal amounts with water. After gently rubbing the white spot with a cotton swab dipped in the solution, rinse.

If required, repeat this procedure. It also has comparable properties when applied topically. White spots are brought on by fungus and bacteria. Thus this treatment eliminates them by igniting a chemical reaction.

General Care Tips

Heat, light, and fertilization must all be balanced correctly for majesty palms to develop well. Over-fertilized plants raised in warm environments with little light will stretch out in search of more. Without an increase in fertilizer and water, plants that receive too much sun may burn.

The ideal indoor environment will generally include a sunny spot with lots of water and less fertilizer than you may imagine.

When kept between 65 and 85 degrees Fahrenheit this plant can grow rather well. Although it may thrive at normal home humidity levels, it likes excessive humidity.

Running a humidifier might make the plants happier in colder locations where the winter air can dry. Additionally, regularly misting the plant will ensure it receives the humidity it needs. Low humidity can favor the growth of insect pests.

During the growth season, treat with a dilute liquid fertilizer once or twice; do not fertilize at all during the winter. Reduce or cease fertilizing if your indoor palm plant begins to elongate. An excellent option is a fertilizer blend explicitly made for cacti.

Applying Epsom salts will provide enough magnesium and stop the leaves from turning yellow, but it should only be applied once a month to keep the leaves from drying out. Plants may need additional iron to stop further yellowing and leaf loss. For application, follow the directions on the product label.

Pests, including scale, whiteflies, and aphids, can harm majestic palms. This plant is particularly vulnerable to mealybugs and spider mites because of the low humidity levels. If possible, locate the infestation as soon as possible and deal with it using the least hazardous method possible, such as horticultural oil.

The palm tree flourishes in direct sunshine because it is a tropical plant. It takes two to three months after planting for them to be established, which means that their roots are completely formed and are firmly fixed in the earth.

Water them thoroughly twice a week throughout this time, especially in the dark, to avoid the moisture from evaporating too quickly. 

Even while mature palms can withstand drought, they still require monthly watering. You can apply enough mulch or compost to the tree’s base to preserve moisture and control temperature, especially during the winter. Two to three times a year are appropriate for applying slow-release fertilizers.

You should identify the source as soon as you notice white spots starting to emerge on your palm leaves. Most often, it’s something tiny, like a bug, but occasionally it’s something bigger, like a sickness. White leaf patches are typically caused by fungal infections, which can be challenging to identify without a decent microscope.

A lack of water supply is just one of the many causes of white patches. The leaves can be soaked in water for about 15 minutes to get rid of the white spots, but if they still appear after that period, soak the leaves for longer.
