Monstera’s new leaves turn brown and die off

Question

My monstera keeps getting new leaves, but by the time they grow big enough they turn brown and die off. They never got to the stage where they would flatten out. They die still rolled up. The older leaves are fine, but no new one survives. Any idea why? Thanks!

Answer 1

My guess would be that the soil is too wet. Monstera, like all philodendrons, likes to have plenty of air around its roots. When the soil in the bottom of the pot stays too wet, in other words doesn’t dry out enough between waterings, the roots can’t breathe, and root rot set in. Test the moisture in the bottom of the pot; on a moisture meter, it should register 1/2 way between dry and moist before you water again. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/testing-moisture-in-plants.htm
If you find the soil is too damp, you’ll want to take steps to correct the situation: https://www.gardeningknowhow.com/plant-problems/disease/treating-root-rot-gardening-tips-for-housplants.htm

Thanks for the quick answer. I’ll try and fix the problem.
