Hello, I have planted a Yucca Thompsoniana in my front yard, in a biodegradable pot with holes cut all over the pot, bottom too...and its been in the ground for 1.5 years. Its appearance on the leaves has changed; it went from green leaves with sharp dark brown points but now has yellow extending from the dark sharp points about 1.5 inches up the leaf and terminating in a darker brown stripe. I dont know what this means but I really want to keep this plant healthy and numerous online searches tell me that its either getting TOO MUCH water or NOT ENOUGH water...I'd really like to know which direction to go so I can help it out. Any input would be appreciated.
