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.
