Feed while the plant is growing

Use a balanced liquid fertilizer once a month while Monstera deliciosa is actively growing.

April through September is the usual growing-season window. Use visible new growth rather than the calendar alone to judge an indoor plant.

Reduce or pause monthly feeding when darker conditions slow growth. Do not carry the April-through-September schedule into winter automatically.

Resume when the plant is actively growing again. No single restart date fits every indoor plant.

Choose a balanced liquid fertilizer

Choose a balanced liquid fertilizer for the growing season. Do not substitute a high-nitrogen, slow-release, or homemade formula.

Read the label for mixing, application, and safety directions before the product reaches the pot.

Wait if growth has slowed or the plant is stressed

Do not fertilize because one leaf is damaged or growth looks weak. Check light, the potting mix, drainage, and roots first.

Wet roots can decline, and dry air can brown leaf edges without a nutrient shortage.

If growth has paused or the plant is stressed, do not fertilize yet. Wait until active growth resumes.
