Prayer plants do well if you give them a boost of fertilizer in the early spring. Use an all-purpose liquid fertilizer, and dilute it to half strength. Using a full-strength fertilizer may burn the leaves. Use a 10-10-10 formula at half-strength, and feed the plant every second week through to September

Temperature. 65°F–85°F (18°C–30°C). It's best not to let it go below 60°F (15°C).
Maranta leuconeura does not need frequent repotting, so be sure to review the list of signs to confirm that the plant actually needs a bigger pot.
