I did iris, yucca, lily root division and put the roots in 1 gal containers using mulched medium. If there are ten pots of same root division only one or two pots will flower. Why??? All the conditions are identical!!! How can I make them bloom at the same time???
Hi, Not quite sure if u mean,all 3 plants flowering at the same time or the same plant and some not flowering. But 1st, these 3 plants all bloom at different times. Well most of the time, depending on the species of your Iris and Lilies. Iris siberica blooms early, but a Dutch Iris might bloom at the same time as your Lily, depending on the type of Lily. Yuccas, depending on their age might not bloom for 5 yrs.
