Monstera Leaves Unfurling. Young monsteras have solid heart-shaped leaves and they almost look. Also super curious if they can split AFTER unfurling or just before like in yours here.
It seems dark to us but its the definition of brightindirect light. Watch this baby unfurl. Black and brown spots on Monstera dont necessarily mean it is is doomed.
I tried changing their potting soil but it did not work.
You can also try increasing the light BUT be very careful. Ever wonder what it looks like for a monstera plant to unfurl new leaves. Pot your Monstera in loose peaty soil to ensure proper drainage and aeration of the roots. Black spots on Monstera can be caused by physical damage.
