Fertilizing Daylilies: Timing and Two-Step Approach

Fertilize daylilies in late March–early April when growth is vigorous. Use 1 tablespoon 10-10-10 per plant now for quick uptake, then apply slow-release fertilizer per label. Water well. Fertilize again after summer bloom fades to stimulate rebloom. Consistent moisture is key for repeat flowering.

Time-release fertilizers need warm soil to activate; the 10-10-10 bridges the gap.
