I planted two of these Green Mountain Boxwood 2-3 weeks ago in Columbus OH. They are both potted and in my courtyard. I sprayed them with Neem Oil on Friday. Am I missing something?

Hi! I recently purchased this philodendron from Trader Joe’s I think it’s a pink princess bc of the stem colors. When I first got it the variegated parts were brown, but the mostly white leaf was beautiful and it was putting out new growth quickly. The day after I bought it, one of the leaves formed this fluid filled bubble and I ended up cutting it off when I noticed it was growing. I then repotted it into well draining soil and a slightly bigger pot. A few days later and the variegated spots on the leaves are all turning brown now! It gets bright indirect light from both East and West facing windows, and I’m being careful to not overwater. Please help!

Hi Plant Lovers! Does anyone know why some of my Ficus Benjamina leaves are wrinkled like this please? My partner has had this for around 25yrs now (I took over caring for it around 12yrs ago as he was looking quite sorry for himself. The plant, not my partner 😆) and we've never noticed the leaves do this before. I only water when the top couple of inches of soil is dry, allowing it to drain properly. I've checked for pests and can't see anything. It's growing new leaves so seems generally healthy, but these wrinkly leaves are concerning me. Should I be worried?

My neighbor gifted me a beautiful umbrella plant today, however upon further inspection, I noticed it is covered in scale. I immediately sprayed it down with the hose outside and picked off what I can see by hand and used paper towels to wipe both sides of the leaves. Then i spray neem oil all over the plant and will leave it outside for the next few days. Please give me any tips and tricks you have to get rid of this as fast as possible. This is the first time I have dealt with any plant pests. I also cut off badly yellowed or spotted leaves & the ones that were very infested.

Help needed! Noticed a “blister” on my aloe. There is one larger section on left leaf and a small dot on the right leaf. My routine and location have not changed except I put some Systemic granules in the soil ~2 weeks ago (I do this every so often) and spilled a few grains on one of the leaves, I believe it was the left one. I brushed them off but is it possible it created micro-tears in the left and caused irritation? I don’t see signs of mites or bugs otherwise, and have never before. Not sure if anyone has seen this before.

Several of my plants are struggling and I can’t work out why, different plant types too. These plants get: - 12 hours of grow light a day, grow light is about 3ft away - Humidifier for a little more time than the grow light is on, 71% currently - Room temp 20C - Watered based on their own needs, I’m pretty good at watering so don’t think this is the issue Any and all advice is welcome please?

I think my catnip is dying?? It was doing fine a week ago and growing a bunch. I thought I finally figured out why it wasn’t growing new leaves and it was doing so well 😭 but now a bunch of the leaves are turning brown and shriveling up. Is it fungus, rot? Or is it the coco coir??

Can anyone help figure out why my Asparagus Fern is dying? Full sun, repotted recently with an orchid mix, watered usually every 1.5 weeks. Planta says to water around every 3 days, though I feel like that's to much as the dirt is still damp by the time it says to water again.

Please help my pup! I can’t figure out what’s wrong! It was doing fine until about a week ago. It’s such a baby pup I’m afraid if I don’t do something to help it soon I’ll loose it because it’s not quite hardy enough as a mature plant.

My fittonia is getting theses white spots on its leaves does this mean it’s too cold or something else? She’s been sitting by my window.

Rubber Tree Dilemma & Advice I was out of the country for 2 months, and my propagation system failed for my rubber tree, so it was bone dry and pretty limp when i returned. I added before and after pics for context. I cleaned and checked the roots, they seem fine still. But it’s been ~2 months since i got back and the leaves are still droopy and the stem is still leaning a little. There is a new shoot which is good. But i don’t know whether to cut the stem down to 2 inches and start over, or try propagate from scratch using the new shoot. Or simply keep monitoring. Any advice?

Can anyone tell me what is going on with this cherry tree. Black edges on the leaves. No spots anywhere else. Just all of the edges of every leaf. It’s in a large pot, it’s about 5 years old. We have had a lot of rain recently but is outdoors and soil seems to dry out in a good timely manner. It’s in part shade so doesnt get sun burned. It was fertilized recently by someone else so wondering if it can be fertilizer burn? I keep getting different answers from planta and google. Planta says underwatered but we literally had 4 days of torrential rain and it gets watered regularly as well. Google says fungal but shows pics of spots on leaves not on the edges only. Any help would be appreciated.
