Planting windmill palm
Planting directly in the ground:

- Follow our planting advice.
This palm, like most others, loves having very well-draining soil. Make sure to increase drainage by adding sand, clay pebbles, or other similar amendments to your garden soil.
Growing in pots
- Anticipate having to water regularly in summer so that the soil mix never gets completely dry.
- Give the plant good light, but if you’re in warmer regions, it’s best to avoid scorching locations.

- After that, eliminate dead, dried out and yellow branches whenever you notice them.
Good to know about the windmill palm
The hardiest of all palm trees succeeds in resisting winters very well, even temperatures dropping to the 5 to 14 °F range (-15 to -10°C). It has even been reported to survive -5°F (-22°C)! Native to China, this palm tree also goes by the name Chusan palm. It grows gigantic leaves that reach to nearly 6 feet long (1.5 meters).
- Growth is relatively slow at the beginning, but then it tends to speed up as years go by.
The advantage of this palm tree is that, overall, it grows rather fast.
Mulching in summer will help it retain the moisture it needs.
