Daylilies grow well with water, fertilizer and mulch. The daylily bears large, orange, red or yellow blooms. Their blooms last only one day. A new bloom appears the next day, so there is constant blooming throughout the season.
Daylilies thrive in the garden with proper care. They grow best when planted in a sunny area, as they need six hours of sun per day. If planted in partial sun, they produce fewer blooms. These flowers can grow up to 4 feet tall. They start blooming in the spring and continue throughout the fall season.
Water is the most important nutrient for daylilies, and the flowers benefit most from watering up to 10 inches deep into the soil. These flowers require about 1 inch of water per week. Daylilies are not fussy flowers and can grow in most soil conditions. Applying one fertilizer application to the daylily bed in the spring of each year is sufficient.
The daylily also benefits from mulching to help the flowers retain moisture. When applying the mulch, it should be pulled back 2 inches around the base of the plant. Avoid having too much moisture collect at the base, because it can cause the roots to rot. Mulching also keeps weeds out of the garden.
