My monster leaves are browning, what could be wrong with ...

5ft to light, indirect
8” pot without drainage
Last watered 1 week ago
Hi Samantha, it says your pot doesn’t have drainage, is that correct? If so, that might be the problem. Maybe the first signs of fungus or root rot.
Generally I'd say overwatering is ABSOLUTELY the prime cause of this type of browning on Monstys ... But it can quickly lead to root rot so you need to be careful!

I'd immediately cut back on watering and look to repot her asap... Remove any brown or squishy roots with sterelised snips or scissors, and put her into a pot of similar size but WITH drainage holes! (You can put a plastic nursery pot into your ceramic pot... Or go for terracotta! It wicks water away from the roots).

You want a REALLY chunky soil mix, standard houseplant potting mix won't cut it I'm afraid! You should have perlite and bark in the mix as a minimum requirement really... There are LOTS of good Monsty-specific mixes out there (I use soil Ninja personally) or you can mix your own (which is actually what I do, as I have LOTS of different species and SN do a great, peat-free base mix and LOTS of different soil additions so that you can tailor your mix to your plants needs... I can give you my "recipe" if you're interested? Lol πŸ˜‚).

They like moisture, but more humidity than soil moisture! You need to let her dry out at least 1/3-1/2 of the pot depth in between waterings... Greg will give you a guide but nothing beats the dip test (stick your finger in the soil to your second knuckle, and if it feels at all cold or damp... Wait a week! Then try again) xx
Thank you both! I’d love the β€œrecipe” lol my pot has one drainage hole so that, and the fact that my soil is not very chunky, may be the issue. I’ll repot her and look at the roots asap!
No worries hun! πŸ₯° I use 2 parts coir, 1 part pumice or perlite and 1 part vermiculite or zeolite. You can chuck in orchid bark too if you like... But I don't with my Monstys as the perlite/ pumice retains water and the zeolite/ vermiculite retains nutrients... I find adding bark, whilst making the soil chunkier tends to keep it a bit too damp for my environment (but I do live in Scotland, which is... Well, damp!! Lmao 🀣). I sprinkle a little activated charcoal in the bottom of the pit to help stave off root rot and after the first layer of potting mix, just before you "plant" her, a sprinkle of worm castings for nutritionπŸ₯° I know that sounds like a LOT if steps!! Lol πŸ˜‚ but I have several and they're all doing really well!

I love mixing my own... I have loads of different species of plants and find it's actually cheaper buying a decent base mix and additions that different mixes for different plants, plus you can play about and tailor your mixes πŸ˜‰ you learn as you go! Which is always fun, and you'll find what she like best πŸ₯° xxx
