Divide and Conquer

How about water and maintenance?

Sam: You'll get more flowers if you water regularly. Soaker hoses and drip systems are good because they deliver moisture to the roots where it's needed--not on the leaves. One inch of water a week is best. Overwatering causes problems.

As flowers fade, you should deadhead. Once blooming is done, I cut the scapes (stalks the flowers bloom on) back to the ground so they don't go to seed. This encourages reblooming.

When and how often do you recommend dividing?

Sam: It really depends on the daylily―usually anywhere from two to five years. When flowers become smaller than normal, I know it's time to divide. You can do this in the spring or fall. If I divide in the spring, I replant what I can and pot some of the divisions to share.
