Short answer
Monstera deliciosa frequently experience stalled growth when they lack sufficient bright, indirect light to fuel their expansive foliage. The most effective fix is to move your plant to a spot where it can see more sky, ensuring it receives several hours of bright, filtered light daily.
Stalled growth in Monstera deliciosa is a common frustration, often manifesting as a failure to produce new leaves for several months despite otherwise green and stable foliage. While slow growth during the darker winter months is normal, a total standstill during the growing season usually indicates a mismatch in lighting or root-zone health.
Monstera deliciosa are vigorous climbers that require substantial energy to push out their massive, fenestrated leaves. In dim corners or rooms with small windows, the plant lacks the fuel for metabolic activity and enters a survival-oriented state of dormancy.
Check: Observe if the plant has stopped producing new growth entirely and if existing stems look stretched or 'leggy' reaching toward a light source.
Fix: Relocate the plant to a position within 2-3 feet of a bright window, preferably one with filtered light or soft morning sun.
These plants grow rapidly and can easily fill their pots with a dense mass of thick roots. Once the roots have circled the pot completely, they lose the ability to efficiently intake water and nutrients, halting new vegetative growth.
Check: Gently slide the plant out of its pot; if the roots are circling the perimeter tightly or growing out of the drainage holes, it is time for a larger pot.
Fix: Repot the Monstera into a container only 1-2 inches larger in diameter, using a well-draining aroid soil mix.
If the plant is in the same soil for over a year, the essential minerals and macronutrients required for leaf production are likely depleted. Without supplemental fertilization, the plant lacks the 'building blocks' to develop new foliage.
Check: Check the age of the soil; if it has been more than 12-18 months since repotting or consistent fertilizing, the medium is likely inert.
Fix: Apply a balanced liquid fertilizer diluted to half-strength every 4-6 weeks during the active growing season.
When to worry
Stalled growth is rarely an emergency unless the existing leaves begin to yellow or drop suddenly. If the plant looks vibrant but simply refuses to grow, it is usually a sign of a happy but hungry or light-starved plant rather than a dying one.

Diagnose my MonsteraYes, a high-quality full-spectrum LED grow light is an excellent solution, especially if you lack naturally bright window space.
This is likely just its natural pace relative to your environment; as long as the leaves are green and firm, the plant is simply prioritizing maintenance over expansion.
Pruning won't directly trigger new growth and can actually deplete the plant's energy reserves; it is better to address the light and nutrition first.
