What to do when Monstera deliciosa leaves have black edges? One trick to help it recover and grow easily

A gardening friend asked: the Monstera deliciosa leaves have developed a ring of black edges, what should I do?

If the leaves of Monstera deliciosa develop black edges, the main cause is poor ventilation; after you water, the potting soil stays wet for a long time, causing the roots to rot. Another case: your ventilation is very good, but you keep watering it for a long time. The potting soil stays in a waterlogged state, which also easily leads to root rot. This in turn causes the black edges on its leaves. Both causes are symptoms on the leaves of rot in its fine feeder roots. Let me tell you the remedy!

Actually, if the black edges on your Monstera deliciosa are not very serious and not all the leaves show this condition, a little fungicide can stop it; we can use mancozeb diluted with water to water it. Cut off the leaves with severe black edges, spray the leaves with mancozeb diluted in water, spraying three times at seven-day intervals can effectively control it, but now it has already entered autumn, the temperature is gradually dropping, and this is also the season when Monstera deliciosa begins to grow rapidly. Since your Monstera deliciosa has developed blackening leaves, it proves your potting soil is not very good either. It would be better to first water once with mancozeb, dilute it with water and spray the leaves, and after the temperature drops, repot it with a complete soil change. Trim off the rotten roots, soak the roots in mancozeb diluted with water, and plant it in new soil; the new soil must be loose and breathable, and do a good job of sterilisation. After planting this way, the new potting soil has plenty of nutrients, and this season suits its growth, so it can quickly take root and grow fast. It is also less likely to develop black leaves again.
