Windmill palm is a plant that is known for its unique leaves that are shaped like a windmill. This palm is native to China and is a popular choice for those who want to add a tropical touch to their landscape. Windmill palm is a slow grower and can reach a height of 20 feet. This palm is also salt tolerant, making it a good choice for those who live in coastal areas.
About soil condition, windmill palm is not too fussy. It can grow in either sandy or loamy soil, as long as it is well-draining. The pH can be anywhere from 6.0 to 7.5. This palm does not like soggy soil, so make sure to plant it in an area that does not stay wet for long periods of time.
So, like the other palm trees, the windmill palm requires full sun to partial sun in order to grow properly. However, this palm is unique in that it can survive and even thrive in colder climates that other palms cannot. This palm is also salt tolerant, making it a good choice for coastal areas.
The temperature condition that is best for a windmill palm is one that is warm and not too hot. If the temperature gets too hot, the leaves of the windmill palm will start to turn brown and wilt. The leaves will also start to fall off if the temperature gets too hot.
Ideal humidity condition for this plant is 60% or above. This plant requires high humidity to thrive, so be sure to keep the surrounding air moist. One way to achieve this is to mist the leaves regularly, or set the pot on a tray of pebbles and water. The key is to never let the pot sit in water, as this will rot the roots.
Mentioning fertilizer, this family of plant is really easy to grow and maintain. Fertilizer should be applied every other week during growing season and can be reduced to once a month during winter. When it comes to watering, the Windmill Palm can be pretty drought tolerant once it's established. Nevertheless, it's still best to water it regularly, especially during hot, dry weather. The root system of this plant is quite compact and fibrous, so it doesn't need a lot of space to spread out.
Pruning windmill palms is a simple process that can be done with a few basic tools. First, you will need to identify the shoots that need to be removed. These are typically the ones that are growing out of the top of the palm or the sides of the trunk. Once you have identified the shoots, use a sharp knife or pruning shears to cut them off at the base. Be sure to make clean cuts so that the palm can heal quickly. Windmill palms are tolerant of most pruning methods, so feel free to be creative. If you want to remove a large branch, you can cut it off at the trunk and then use a saw to remove the stub. Or, you can make several small cuts along the branch to gradually remove it. Whichever method you choose, be sure to sterilize your tools before and after use to prevent the spread of disease.
Propagation of windmill palms is relatively easy. Seeds can be germinated indoors or outdoors, and young plants can be propagated by division. When propagating by seed, it is best to start them indoors in late winter or early spring. Sow the seeds in moistened potting mix and keep the mix warm and moist. Once the seeds have germinated, transplant the seedlings into individual pots. When propagating by division, carefully dig up an existing plant and divide the rootball into 2 or 3 sections. Replant the sections immediately and water well.
Usually, the plant growth rate is determined by the growing conditions. If the weather is warm and humid, the palm will likely grow faster. If cooler and drier conditions prevail, growth will likely be slower.
Common problems for this kind of plant are that the leaves can get brown tips or even burn if the plant is not getting enough water. Also, the leaves can turn yellow if the plant is getting too much sun. If you see either of these problems, you should adjust the amount of water or sun that the plant is getting.
