Hi!
I purchased my monstera plant from a local nursery about a month ago and i’ve Noticed some leaves have black edges or black spots. I’ve also noticed a couple new leaves have a tiny black spot at the point of the leaf. See photos below. I need advice on exactly what to do on how to save this

Background:
-I’ve water it only when the first two inches of the top soil are dry.
-I have not re-potted. It sits in a 10 inch pot
-my plant sits away from direct sunlight and sits by my sliding door to the balcony
-I watered it last week and the top is still moist (is this a problem?)

Help please ! Appreciate it!

I am no expert. If I buy an indoor plant, I will definitely repot it. Sometimes, these plants might have sat in the same pot for a while and the supplier just tops up the compost so that the plant looks nice in the pot in the shop. By the time the pot reaches you, the plant will probably exhausted the nutrients in the compost. I bought quite a few mother in law tongues. The soil was coir and therefore had few nutrients in it. One has only got one long root.

Some "experts" suggest only watering when the compost is finger-touch dry on the top bit of the compost as this will prevent bugs from laying eggs in moist and warm compost. They also suggest putting a bit of grits on top to discourage bugs from laying eggs.

You could google your plant name + black spot on ?? leaves to see what people suggest and gauge the usual culprits..

Appreciate your insight! I will definitey see if repotting works and try to use a breathable potting soil. Do you think I should cut off the bad leaves?

I would use some water from an air purifier or clean distilled water and some cotton pad (for washing away make up) to clean the leaves including the underside and if the black spots are big or numerous, I would cut the leaves away. You can get a weak feed or use some container compost to top up.

You probably can find out more from him and if you key in Monstera, you will get more results ... Feed your font of gardening knowledge.

Hi there,

I wanted to follow up and ask if your plants ever recovered and if so what did you end up doing? I have noticed my plants are starting to get those exact same spots and have repotted, watered, misted. I seem to have contained the situation but it’s affected too many leaves that if I cut away the bad leaves, I’d be left with about 4 leaves! Mine is set with a moss stick so it will look quite sad if I trim it back...

Thoughts and pointers?

Thanks
