Can I cut back my giant lilies and big leaf asters?


The lilies are bulbs so maybe like tulips they have to stay until October or November? The asters are blooming now. So cool! Thanks!

    Bulbs can be cut back, but to maximize the health of the bulbs, try bundling the tops with raffia, or other ties, until completely dead. At that point the bulbs are dormant and can be removed or just the tops gently pulled off.

    Hi Susan. I'm Cindy. It really helps to dead head the lilies while growing but do not cut the stem back. The stems will green and produce the energy needed for next year's blooms. Wait until the lilies have died completely and then cut them all back to the soil.

    Hello there, Susan - it sort of depends where you live and what gardening zone you are in. In my zone 4b gardens, I cut the tops off of my lily stalks so they don't put energy into making seeds. I leave the rest of the stalk until it starts turning brown (which is sometime in September) and they cut it to the ground. With the asters, just wait until they are done blooming for the season and then it's okay to cut them back. Good luck with your gardening!

      I have a Lilly that grows through the Autumn and it’s huge now I’ve heard it called a school house lily and an Oxblood Lily and here in north Florida I can cut it back almost anytime from early spring to late fall and it still gets big. Like Joanna said it all depends

    Hello. I cut back my bulbs (tulips, & daffodils) after they have finished blooming to keep my gardens looking clean. Mums and Asters I also cut back after they have finished blooming. Sometimes we end up getting snow before I can get to them so then I leave them until Spring.
