Title: Soaptree yucca falling over in Mesa AZ
Answered by: Barbara Medford
QUESTION:
My soaptree yucca is about 5 ft tall and has fallen over. Does this plant require staking for I thought not, or is something else going on with it?ANSWER:
This USDA Plant Profile Map shows that Yucca elata (Soaptree yucca) is native to Maricopa County, AZ, so hopefully that rules out the plant being in the wrong environment. By following the link above to our webpage on this plant, you will learn that it can grow from 5 to 25 ft. tall, and there is no mention of it bending over. One of the pictures from our Image Gallery below shows a Soaptree yucca which looks to be about 5 ft. tall. Here are the growing conditions for this succulent:
"Growing Conditions
Light Requirement: Sun
Soil Moisture: Dry
CaCO3 Tolerance: High
