When grown properly under ideal plant conditions, this plant can grow up to 3 -10 ft per year, and their striking height makes this plant ideal for planting in grooves and large areas, but due to their thorny leaves and massive size, they are not very good choices for yards.

Sometimes, maintaining some species of this plant can be problematic. In most of its matured trees, the dead fronds usually drop off as the trees grow, and the younger trees also tend to hold onto these dead fronds.

So as these dying trees collapse against a trunk, they create a shaggy skirt of dead and dried yellow or brown leaves known as thatch. Sometimes, these thatches are formed on the trees, and many people recognize them as part of the trees while others remove them.

The primary reason why people who remove them do so is because this thatch serves as a breeding area for rats and vermin and a fire hazard.

Some cities also make it legal for residents to remove the thatch from their trees, and sometimes it becomes daunting and requires a professional to get it off when the trees get older.

If your tree is still smaller, you can remove these fronds yourself, and you have to wait until they get dehydrated before you decide to remove them.

You can achieve this with a pruning knife or any other type of sharp knife that you have around, but you have to be very careful so you do not hurt the significant parts of the tree or even yourself.

Some essential factors you should consider so you would be able to take care of your Mexican palm trees properly are;

1. Climate And Soil

Mexican palm trees prefer well-draining and moderately rich soil, but they can also survive properly in sandy and poor soils as long as they have a high draining capacity.

You can grow your young plants in a container or a small flower pot and place them to give your decks and patios a tropical look but make sure you do not plant one in a small yard since these plants need open areas to grow well.

There are some parts of Florida and California where these plants are considered invasive, and if you live in these areas of Mexico where this plant is an unwelcome guest, you can consider planting a Guadalupe palm instead; these species are a bit smaller, and you cannot view them as invasive, and they can also be grown in zones 10-11.

2. Watering And Fertilizer Application

it would be best if you water these plants at least once a month, although they are tolerant to salt and drought.

The fertilizer needs of this plant vary depending on the soil type they are planted. Still, for a general maintenance recommendation, you should apply 1 ½ pound of 8-1-10-4 palm tree fertilizer for every 100 square feet area.

3. Pests And Diseases

A common disease the Mexican palm tree suffers from is Ganoderma butt rot, a soil-borne fungus affecting all palm species. This fungus spreads upwards from the soil until it destroys the plant entirely by causing the leaves first to drop, and then the tree eventually dies.

There is no known cure or prevention for this fungus, so make sure you keep the surrounding areas of your plants clean, and whenever one of these plants gets infected, remove it from the rest as fast as possible so it does not affect others.

Another disease common to this plant is the thielaviopsis trunk rot which causes the tree’s canopy to fall without warning. You can also be able to refrain your plants from this disease by pulling off the lower leaves gently before they drop and not wounding the tree with a weed trimmer.

The wind and infected pruning tools disperse the trunk rot diseases, and there is also no chemical cure for this ailment. There is not much trouble with these plants and pests, but you should avoid buying leaves with visible holes from borers.
