Wisconsin Extension recommends feeding container-grown Lantana camara once a month during the growing season. Treat that as an actively growing container instruction, not a universal indoor winter schedule.
How to feed Lantana camara
Container-grown Lantana camara can receive fertilizer about monthly during active growing and flowering conditions. That outdoor-season cadence should not roll automatically into a low-light indoor winter.
Check for active growth
When to fertilize
Feed during active growing and flowering conditions. A plant moved indoors for winter should not automatically receive the outdoor monthly routine when light and growth have fallen. The sources do not set a precise indoor stop or restart date.
Follow the product label
Fertilizer type and dose
The container guidance supports a regular fertilizer for active-season growth, but does not require a named product or nutrient analysis. Do not infer a high-phosphorus, high-potassium or concentrated fertilizer from the bloom query.
Inspect a stressed plant before feeding
When not to fertilize
Too much fertilizer can reduce flowering, so weak growth or few flowers should be checked against light, water and season before increasing feed. Excess water can also reduce bloom. Flowering response is not a dose-based salt threshold.
