Hi all! My dieffenbachia has been struggling since I brought it home and about a month ago I realized it had root rot. I sprayed the roots with hydrogen peroxide, trimmed infected roots, and replanted in a new pot with well draining soil. Fast forward to today and it is still struggling so I checked the root system and while some new healthy roots have formed, some are still rotting. I just gave it a good wash, root trim, and sprayed with peroxide. It basically lost most of its root system at this point, so would it be appropriate to put it in a glass and try to get some new roots to prop before replanting? I haven’t been overwatering it and check the soil with a chop stick to ensure I avoid that. Either way I’m at a last ditch effort but it has a few growth points so I don’t want to give up on it 😭

Brown leaves :( what’s going on? Should I move it out of the nursing pot into a real pot?

Any recommendations on getting rid of fungus gnats?

I cannot for the life of me figure out how to stop the leaves from browning? The soil feels dry about two inches deep so sometimes I water it early but I feel like it’s still slowly dying for me over time. Any thoughts?

I have been battling mealybugs on my plants for a while. I eventually gave up and used systemic pesticide for them. I used the granules. Maybe I over treated them, I’m not too sure but now I noticed my plants are having some issues on the edges and looking very dull. Does the attach look like the bugs haven’t gone away or is this a result of them being unhealthy due to the treatment? I also have not watered since the treatment due to the soil being moist. They are just starting to dry out. The last watering was with the granular treatment.

I’m a beginner and I’m trying to grow tomato plants. All of my leaves started getting little white edges on them. They’re only a month old and I’m scared they’re already all dying. What’s happening?! They’re just babies!!! Is it because they’re too close together? Their roots aren’t even touching. I’m going to move them farther apart once it gets a little warmer and I can move them outside.

I don’t know what’s happening to my succulent! He seemed healthy 2 weeks ago. I’m having a hard time telling if I’m over or under watering? The leaves are very thin and soft.

So I’ve had this guy for a while now (I got her like this) and I haven’t seen any improvement or any deterioration. Any ideas for what might be the cause for her stunted growth and curled leaves? She’s getting an in between of bright indirect light and shade, and I’ve been watering her when only thre very bottom inch or so of the soil is still moist. Ps. The leaves are very hard, I know baby rubber plants do have more rigid leaves but this seems like more.

Ayyyy! Anyone got tips for Thornthrob? She’s a Tom Thumb and I accidentally ripped out one of the lil ferns out of the multi purpose dirt, roots and all. It was sad but I still have the rest :3

Hello, I’m a new plant parent so im not really sure whats wrong. My baby aloe vera is so small and thin and the tips are starting to brown. Is it overwatering? is it underwatering? something else? She sprouted from an adult aloe plant that is happy and healthy so did i just replant her wrong?

Mango seedling

I would like to know if this is normal for my mango seedling it has had lots of new growth but their are little bites on the edges of the leaves and I would like to know how to prevent this thanks. 🤗 Edit: I have had a problem with spider mites but I got rid of them pretty easily so could they have been the problem?
