Daylilies are herbaceous perennials that are known for their brightly colored flowers and long blooming season. They grow from clumps of grass-like foliage and can reach heights of up to 3 feet. Daylily flowers can come in a variety of colors, including yellow, orange, red, purple, and white. They prefer full sun and well-drained soil, and are drought tolerant once established. Daylilies are easy to care for and require minimal maintenance. They are also deer and rabbit resistant, making them a great choice for gardeners looking to add color and texture to their landscape.

Planning Your Garden With Daylilies

As you plan your garden, it's important to think about the spacing, size, light, and nutrient requirements of all of your plant and how they'll grow together.

Some plants require more water than others, while other plants require dry soil. At the same time, some plants prefer full sun, and other plants need the shade to survive.

By studying what each plant requires and planning ahead where all of your plants will grow best, you can optimize your garden space.

Life Cycle Daylilies are perennial plants.

Water requirements Daylilies prefer moist, well-drained soil and should be watered regularly to keep the soil moist, but not soggy. They need an inch of water per week during the growing season and should be watered deeply. During hot weather, they may need to be watered more frequently.
Fertilizer The amount of fertilizer used when growing daylilies will depend on the type of fertilizer used, the soil type, and the age of the daylilies. Generally, a balanced fertilizer with an N-P-K ratio of 10-10-10 should be applied at a rate of 1 to 2 pounds per 100 square feet of garden area. For established daylilies, a light application of fertilizer should be applied in the spring and again in the summer.
Soil pH Daylilies prefer a slightly acidic soil with a pH of 6.0 to 6.5.
