Fertilizer for Prayer Plant: NPK Guide and Application Rates
Prayer Plants (Maranta leuconeura) are charming tropical houseplants named for their habit of folding their leaves upward at night, resembling praying hands.

When Should You Fertilize Prayer Plant?
Fertilize prayer plant during the active growing season, typically April, May, June, July, August, September. Reduce or stop feeding during fall and winter when growth slows.
Apply quarter-strength balanced liquid fertilizer every 4 weeks during the active season. Always check soil moisture before feeding.
