The Q&A Archives: Yucca Won't Bloom

Question: I have a 4 year old Yucca in my backyard that only bloomed the first year and not since. I live in Michigan and the plant is in full sun.

Answer: It may be that the yucca in your yard is growing in soil that is too rich. If a plant is overfertilized, it is less likely to bloom. If you think about the yucca's native arid, desert environment, you'll see what I mean. You may need to transplant it to a drier, less fertile soil, or put it in a pot so you can control the nutrient supply. Perhaps a root pruning, acheived by slicing through part of the root system with a spade, will persuade it to bloom, as this will also cut down on nutrient uptake.
