Why is this happening to my prayer plants? I have a humidifier for them and they also have a pebble tray under them they aren’t infront of a window but they have a grow light for 12 hours a day and they are in a mixture of potting soil, orchid bark, and perlite medium idk what I’m doing wrong😔😔

Hi all! My peace Lily never usually gives me problems. She only drooped when she needed a good water then would bounce back the next day. Now she’s drooping and I don’t know why. I repotted into a bigger pot (6” into 8”) about 20 days ago. And I water about once a week. Today was water day but her soil is still moist. She’s been in the same spot since I got her which was a few months ago now (first pic), which is about 7ft away from my big southwest facing window. Some of her leaves are crimped as well. I wonder if she has too much light? I could place her in a shaded corner that still gets some light (second pic) if you think that might help.

Any hope for saving my calathea? :( I stopped misting it in case the spots are from fungus or water build up, and recently switched to filtered water. Would welcome any other ideas

Say hello to my little friends! Found hitchhikers on a syngonium ghost/holly plant I’ve had in my house about 10 days. I quarantine every plant at least a month after doing a complete inspection of the leaves. The bugs must have been in the soil. Because none were on the leaves or I missed them. They are tiny. I was about to brush one off when it crawled! Yeesh!😬 I treated the plant with soapy water in my recycled hand sanitizer bottles left over from COVID. (These Suave bottles make excellent misters putting out a fine spray.)

Hi everyone! I have two Calatheas (not sure what type they are) and I’ve noticed some of the leaves are wilting in a weird way. Some of the leaves are also getting brown spots as if it’s dry, but the soil is still wet so I don’t think it needs water. I’m new to the plant parenthood so I’m not quite sure what to do. They seem overall healthy and have new leaves growing, but I’m sure there’s something going on. Can someone please help? What should I do? 😔

I’m starting to notice bugs that are hiding in my plants soil, some look like this & other ones look like this but with a bigger body & smaller legs. I just watered my plants today, that’s why the soil is wet looking. I usually let them dry out a little bit before watering again. Any idea on what these bugs are? How can I naturally get rid of them? Moneys a little tight in my house.. They’re in my vegetable/herb plant soil, but none of my actual houseplants soil.

Hope philo browning tips: - lives next to a humidifier that constantly runs and under a grow light - I mist almost every other day with a capful of dr. Bronners soap to help mitigate fungus gnats - I feel confident in the watering schedule using a meter to only water when it hits the line between moist and dry (I do not let it dry out). - liquid fertilize once a month - soil does read high alkaline, wondering if that might be an issue? Otherwise I’m stumped. Had this guy for 9 months now and most new leaves look healthy. Spotted one small one with similar browning.

What is going on with my Alocasia Nebula? I’ve had it for a couple weeks now and it’s slowly started to look like this. I’ve only watered it once since I’ve had it and it’s kept near an east facing window that has a sheer curtain over it, in a room with a humidifier so it’s consistently got 50-70% humidity. Not sure what to do with this!

Need help with two very sad looking pothos - one marble queen and one neon. Not totally sure what happened but these two started getting really leggy and sad after I repotted them this spring. The neon one had root rot issues in the past from being grown in water so could’ve been that. Not sure about the marble queen, I think the pot might’ve been to big for it. I chopped and propped a lot of them in hopes that I could recover them and the neon pothos started regrowing some new leaves but they are much smaller. They both get plenty of morning light from an east facing window. Any recommendations on how I could make them look more full again and have them start producing bigger foliage?

Hi! I’ve had this polka dot plant for about a year and it’s always been pretty unhappy. I’ve changed the watering schedule a lot but that hasn’t really had an impact. Right now it’s watered every 10 days or so. It’s next to a west facing window so it gets direct sun for a few hours everyday. That part that gets the most seems to be the happiest. Could it be a light problem? I plan on repotting soon to see if that helps!

My olive tree is thriving but should i be pruning off the bare branches at all? This is my first attempt at this type of plant and I don’t want to ruin my progress so far
