Fast growing palm species
Compared to other cultivated palms, Washingtonia robusta is considered to be fast growing. Although these are encouraging prospects, no precise, generally valid and binding statements can be made for annual growth.

In this country, the palm can never grow under ideal conditions in its native Mexico. Climatically different regions as well as annual weather fluctuations have a decisive say. Not to forget: the harsh winter!
Experience in cultivation
Attentive owners have observed that the fan palm is capable of:
- in the first year shoots of 2-3 fanned fronds
- Plant size up to 70 cm after just one year
- thereafter the new shoot increases annually
- after all, up to 20 new palm fronds are possible per year
Note:
Reaching heights of up to 30 m outdoors, the Washington palm only brings it to a height of about 3-4 m here. This is primarily due to their existence in the bucket.
A growth-promoting location
Like any palm, Washingtonia robusta needs a sunny spot to grow quickly. Clear the conditionally hardy Only palm in when frost is on the horizon. During a bright, between 5 and 10 degrees warm wintering growth slows down, but never stops entirely.
Deep pot is important
Rapid growth cannot occur without a healthy root system. Washingtonia would like to stretch its roots deeper, the width of the pot is of secondary importance. If you repot a young palm into new substrate every spring, you should also make sure that the new pot is at least a third larger than the old one.
Further care for more growth
Plenty of water during the growing season is a prerequisite for high annual growth. Nutrients must also be available from April to September, whereby a standard NPK green manure is sufficient. But if you deviate from the manufacturer's recommendations in order to accelerate growth with a lot of fertilizer, you will harvest yellow leaves.
