From searching Google are the brown spots scale insets? I just noticed today and it’s only effecting 3-4 stems but noticed ants as well so expecting them to spread. What’s my best course of treatment??

My flaming Katy has started to have soft droopy leaves and the lower leaves near the soil these brown and yellow spots. Many of the leaves on the bottom have fallen off. I followed the watering instructions from this app exactly and the pot has drainage. I’m not sure what happened?

Need help with my monstera adansonii Has well draining soil, sits by humidifier, gets watered when soil is about dry. Used to sit in a warmer spot that got light especially in the morning but moved it to a more bright indirect light spot because it started getting yellow and curling. Any tips or ideas on how to stop yellowing and curling ?

Hello! I took over this cutting from a friend about a week ago. It has been doing so well and so healthy!! I can see that it’s definitely been over watered so I’m trying to let it dry out but I also noticed something strange on one of the leaves.. it’s only on this 1 leaf. I did treat with neem oil as preventative (no pests yet). Has anybody seen this or know what it is?? I did notice a few leaves curing as well.. Thanks guys you’re a life saver!!

Hi, plant newbie here! I planted this zahara yellow zinnia two weeks ago and it now has holes in the leaves. Plants says it’s snails but I haven’t see. A single one. Any tips or suggestions? Thanks!

Just reported my philodendron sodiroi last week and treated with neem oil yesterday (as a preventative, no pests so far) and the next day I found the bottom leaves a neon yellow!! Have been watering once a week, last water was last Sunday, about 4 ft from a window, has a grow light as well.. it does not look like the kind of yellowing you get from over watering.. and happened overnight! Anybody seen this??

I am just baffled with my spider plants. Appears to be rotting from the middle out. On most all my spiders. The soil is not wet. No changes with the care. I tore apart the roots, no rot. Any help out there? Anybody else have this?

I had this potted hydrangea for a few weeks now. One of the flower head wilted suddenly today . It was very strange because all other heads are fine, also it is not a fully bloomed one. The soil was still damp when this happed. I water it quite frequently (2-3 times a week). Any ideas why ? Thanks in advance.

Hello, I’ve been having some issues recently with my ZZ plant. The leaves have slowly been going yellow then brown, dry and snapping off. For a bit of context I’ve had the plant for around 4 months and it has been heathy and growing rapidly the entire time. I noticed that the pot it was in started to warp and thought it was time to repot into something bigger. I went a size up and used just regular potting soil with PEAT (not sure if that’s relevant or not) after repotting growth slowed then stopped entirely I assumed it needed to settle after being repotted. However around two or so weeks ago it started yellowing. The soil was still damp (I have been following the Planta watering instructions since the begging and it has always been fine) and researched that it could be getting affected by root rot so I took it out of the soil again to check and seemed fine but I’m not an expert. I then repotted it into a 70/30 mix of a new potting soil (specifically for houseplants) and perlite. The two close up pictures were taken about four days apart and you can see the progress of the browning leaves. Any idea what I should do to save this plant?
