Florida often experiences long periods of dry weather which typically causes government to restrict water availability. Many of the plants we enjoy such as the daylily suffer. There are ways to keep the plants we enjoy growing nicely yet limit the amount of water usage.

Modify The Soil.  Sandy soil doesn't hold water long enough for plant roots to get the amount of water needed. Fertilize easily washes through sandy soil again denying plant roots what they need. A solution is to change the soil close to a plant to make it more water retentive. 

1) Determine about how far your plant sends out it's roots.  Next determine about how deep the roots go.  Daylily roots can spread 18 inches. This is the space you want to modify.

With the target area defined next add items that hold water in a soil such as organic material (leaves, pine needles, wood chips, horse or cow manure, grass clippings, peat moss, and compost). Over do it. Store bought organic products are composted cow manure, top soil, peat moss  and wood chips. Walmart sells a 40 pound bag of composed cow manure for about $1.30 a bag. Dirt cheap yet very effective. Use one 40 pound bag per daylily to achieve a dramatic reduction in water usage plus an increase in plant vigor
