Under glass, use a balanced liquid feed every two weeks during the growing season. Treat this as an active-growth routine, not a fixed calendar for a low-light indoor plant.
Coffea arabica feeding guide
Use the cited two-week schedule only for greenhouse or conservatory growing-season conditions. Do not copy it into a low-light winter room without checking active growth.

Check for active growth
When to fertilize
The growing-season routine pairs free watering with feeding every two weeks. Winter care changes to moderate watering, but no winter feeding interval is given. Do not continue the active-season schedule automatically.
Follow the product label
Fertilizer type and dose
Use the balanced liquid fertilizer specified for the exact Coffea arabica under-glass profile. A consumer brand or slow-release product is not established as an interchangeable choice.
Inspect a stressed plant before feeding
When not to fertilize
When growth is weak, check water, humidity, light and roots before adding feed. Pale leaves, brown tips or poor growth do not by themselves confirm a feeding problem.
