Liquid fertilizer provides quick results and allows more precise control, making it ideal for active growing periods. Slow-release fertilizers offer convenience with single applications that feed for months with less maintenance.
6. Should I fertilize my peace lily in winter?
Reduce fertilizer application in winter when peace lilies naturally slow growth. Apply at half strength or extend the time between feedings to 6-8 weeks during cooler months.
7. What fertilizer helps peace lily bloom more?
Bloom-boosting fertilizers with higher phosphorus content, such as 3-4-5 or 10-15-10, encourage more abundant white blooms on peace lilies. Consistent feeding during the active growing season produces the best results.
