My mint I got from Sainsburys has been growing well on the kitchen windowsill - it gets plenty of light, water and the temp in the flat is always constant.
But, it is has gotten leggy and whilst it produces tiny leaves, they quickly die before they have even grown to a bigger size. The bigger leaves are turn brown around the edges.
Something tells me it might be root bound, but there are no protruding roots coming out of the holes at the bottom of the pot.
If it is, can I just cut the roots back? I ideally want to keep it at the same size without having to put it in a bigger pot (we are lacking space).
Does anyone else have any advice what it might be?
Many thanks in advance!
