Planting Daylilies from Rhizomes (Not Bulbs): Timing and Technique

Correction: Daylilies Grow from Rhizomes

Daylilies (Hemerocallis) have fleshy roots and a crown — not bulbs. Bearded iris and cannas also grow from rhizomes.

Best Planting Times

• Spring: After last frost (late April–May in most zones).
• Fall: At least 30 days before first frost (Sept–Oct).

Planting Method

1. Dig hole wide enough to spread roots.
2. Make a mound in center; place crown on top, roots down.
3. Cover crown with 1 inch of soil.
4. Water well; mulch lightly.

Bloom Expectations

Spring-planted may bloom lightly first year. Fall-planted usually bloom well the following summer. Rebloomers like ‘Stella de Oro’ extend season.
