Given the Washingtonia palm growth rate, it is apparent that it is a tolerant plant. However, that does not mean that you do not take adequate measures to care for it.

 

Here, we will discuss the care guide for the Washingtonia palm tree.

 

Planting

Firstly, before you plant your Mexican Fan Palm tree, you should prepare the planting area. So, pick a spot where the tree receives full sun and can grow to 100 feet tall, without any disturbances to any building or the power line in the region.

 

Further, since it grows wide, you should leave about 25-30 foot space for the plant’s spread. Next, you need to dig a planting hole with a round point shovel, which should be at least two times the breath and as deep as the young palm’s rootball.

 

Sunlight

How fast do Mexican fan palms grow depends a lot on the conditions it is exposed to. So, even when it can tolerate part shade, giving it full sun for proper growth is ideal.

 

Watering

Even though Mexican Fan Palm is a desert palm, it enjoys well-watered growing conditions. The plant is not very drought-tolerant, especially when newly planted. You may plant them in areas that have underground surface water.

 

While planting, you must feed it with 4 to 5 gallons of water to drench the soil wholly. However, it sure can survive with less water once it has been established.

 

Regardless, it would be best to water your palm moderately in each season except winters. In the colder temperatures, you should keep the plant dry.

 

However, at any time you are not confident whether you must rewater or not, touch the soil about two inches down. If the soil seems dry, you can consider rewatering.

 

Temperature

The temperature that the plant has to face every day also determines the Mexican fan palm growth rate.

 

It is a winter-hardy plant and somewhat resistant to cold weather. It is hardy to USDA hardiness zones 9 to 11 and can tolerate temperatures dropping to 18° degrees Fahrenheit (-8° C). Anything below that may not be received well with the plant.

 

Fertilizer

As much as the natural factors are essential, even the plant’s feed is also pivotal to how fast do Mexican fan palms grow.

 

So, every other month, make it a point to feed the plant with a controlled-release palm fertilizer in the growth stage. Always opt for a granular or water-soluble fertilizer explicitly designed for the palms, decided only after a thorough soil test.

 

Choose one that has potassium for the palm to resist diseases and get stronger, nitrogen to stimulate photosynthesis for the leaves to retain their green color, and phosphorous to maintain nutrients.

 

You can opt for a balanced fertilizer in the 8-8-8 formula for faster growth in spring and summer.

 

Repotting

You do not have to repot the plant immediately. Repotting must be done just once in a year or two.

 

Of course, given how fast do Washingtonia palms grow, it is bound to outgrow the original pot or the shipped container. So, anytime you carry out the repotting process, you must try and increase the pot size by about two inches.

 

This will suffice to accommodate the new growth. Be very careful with the repotting as at the leaves’ end; there will be sawtooth spines.

 

Given the good Washingtonia palm growth rate, they will fill in whatever space you leave for it.

 

Soil

Even though the palm can grow in a variety of soil types, for a good Mexican fan palm growth rate, you must plant the palm in fertile soil with a good drainage system. Your plant won’t have healthy growth in water-logged or soggy soils.

 

Typically, a ratio of 4-to-1 native soil to organic compost can help with a healthy growth.

 

Look For Warning Signs and Prune

If the palm’s fronds start turning yellow, it may be a sign of overwatering. Hence, if you see yellowing fronds, wait before rewatering the palm to let the soil dry.

 

Also, if the fronds turn brown, it means you are underwatering the palm. So, in this case, you should use a well-draining potting mix to strike a balance.

 

When the fronds turn brown or yellow, you could prune them. This can elevate the look of the plant and make way for healthier green fronds to flourish.

 

Control Pests

Mexican fan palm is quite a robust plant, which is not susceptible to disease. But, if you notice spider mites, aphids, or mealybugs near your Mexican fan palm, you need to tackle them immediately as they can intervene with the Mexican fan palm growth rate.

 

For this, you can spray your palm with some water to dislodge the creatures.
