If you wait too long to put in your hoops, the peonies will grow before your eyes and flop to the ground at full-size. The weight of the blooms makes it difficult to support themselves.
In the early years of your plant, you may see some of the hoop, but as they grow into full-size, the hoop will become completely invisible and your plant will stand upright.
We can't get enough of these hoops! We remove them at the end of the season (they snap into a flat shape), store them inside over the winter, and use them again the following Spring.
