Tidewater Daylily Society
Growing Daylilies
Best Growing Conditions for Daylilies
- Full sun (minimum of 6 hours per day)
- Well drained soil rich in organic matter (composted horse manure is great)
- pH 6.2-6.8. Tidewater soils tend to be more acid than this, so lime is likely needed.
- Abundant moisture (no drought stress) during growing season (March through October)
Planting Your New Daylily
- Plant your new plant as soon as possible, either directly in the ground or in a pot to plant in the ground later
- When you plant, add some lime, fertilizer and organic matter into the soil and mix well before planting
- Bury the roots only to the crown of the plant, no deeper
- Build a berm around the plant so that when you water, the water will slowly sink in around the roots
- Water in thoroughly and then use a root stimulant such as Ortho Upstart or Fertilome Root Stimulator mixed according to directions. A dilute solution of high phosphorous soluble fertilizer, 10-16-10, 15-30-15, mixed at half the recommended rate can also be used.
- DO NOT WATER the plant again until you see new growth. Overwatering a newly planted bareroot plant can cause it to rot.
- After it has started to grow, water it once or twice per week during the growing season
- Daylilies are heavy feeders, so make sure it is well fertilized during the growing season. See fertilizer schedule below.
- Label your plant: Bury one label in the ground, as a back up. Add another label so you can read it. Pencil written on plastic lasts longer than Sharpies. Paint pens are good, as are label makers and laser printers.
- Mulch your plants with 2-3 inches of mulch to minimize weed competition and conserve moisture
- Watch for pests and treat as needed: Aphids, Thrips, Spider Mites, Leaf Streak, Rust, and Rot.
Daylily Fertilizer Schedule
- Feed daylilies in March and July with Slow Release Lawn Food (16-4-8) or Espoma Plant Tone or Flower Tone
- Follow up 6 weeks later with amended Hooker Formula or when you need to treat for insects and/or diseases
Amended Hooker Formula
- Add the following to 1 gallon of water and spray the plant foliage: 1 Tablespoon Miracle Gro (15-30-15), 1 Tablespoon Epsom Salt, 3/4 Tablespoon Iron Chelate (liquid iron), and 1 Tablespoon Fish Emulsion
Fungicides & Insecticides only as needed and according to label directions
