The Q&A Archives: Yucca Plants

Question: I have two Yucca plants that I brought from Spokane, WA. I planted them in my rock garden in sun/shade area. Can you tell me how long before they will start to bloom, and what fertalizer to use? My friend said they prefer acid soil and to pour left-over cold coffee or coffee grounds on them. Is this true or false?

Answer: Yucca plants are generally grown in the southwestern states, but in your long, hot summer region of eastern Washington, Yucca should perform well. Expect your plants to take a year to become established in their new homes, and another 3-4 years before they're mature enough to produce blooms. Yucca's grow best in full sunshine and average garden soil that's kept on the dry side. You may want to move your plants to an area where they'll get all day summer sun so they'll be happy enough to bloom for you. Yucca plants don't require acid soils, but coffee grounds are an acceptable source of nitrogen, attract red worms, and make a decent mulch around acid-loving plants.
