I’ve got a very old and large rubber plant that for two months has had gradual yellowing and dropping of leaves.

Leaves in the lower half of plant have been gradually getting stippled then yellow then fall. I’ve lost 5-6 in two months. Growth was good until the most recent leaf on the main stem. Branch growth still seems ok.

It’s in a south facing window in the UK and gets good sun all day. It’s in a large pot with drainage holes - I’ve checked roots and it’s not root bound. I wondered if poor watering and UK heatwaves had caused stress but it’s only gotten worse despite moving it away from window. I’ve not got loads of evidence for pests (no webs, no obvious signs under leaves) but am at a loss.

I wondered if
- nutrient defiency (but fed a month ago and has only worsened) hadn’t really fed before that
- sun burn/ watering stress? But have been very careful for two months and it’s only worsened. Tried moving away from window and shutting blind in heatwave/full sun days.
Help! I love my tree.

I am a first time coleus grower and I love the variety of this plant. I decided this year to plant coleus in an attached flower box for in front of my house. It been a few months stance the wee first planted and they were no larger than about 8 inches. They have done really well with some getting up to 3 feet tall but I am running into a major issue that is hitting the am at the same time. In the past week they seem to all be breaking or snapping or just lifting right out of the soil. They look so healthy otherwise. So am I missing something? Should I be doing something to keep this from happening? Please someone help me save them.

Help with gushers most fan leafs are all yellowing and starting to get a yellowing canopy am I ok to feed high nitrogen still at this stage

Hi everyone! i have a handful of house plants i love very very much im having some issues with! I’m having plants with new leaves and amazing growth i cant even keep up with but some of my plants leaves are turning older growth completely yellow! i’ve had thrips before that i have gotten rid of, no evidence of thrips infection on these leaves (no evidence of other bugs, have also repotted some and check soil) and these plants are other wise incredibly healthy and growing non stop. i haven’t seen this before. and it’s happening in multiple plants that seem to be otherwise very healthy! I’m checking root health on the lemon lime philodendron and i’m not seeing anything to suggest anything other than healthy. in another subreddit someone suggested it was just the plants getting rid of old growth but i wanted more input! i’ve added some pictures for clarification! the first photos are of the “sick”leaf and the second is pictures of the sorce plant! if you have advice i’d love the help im completely stumped! Posting this again with hopes of getting some advice, i had 3 more completely yellow leaves on my swiss cheese that is still growing great and it really seems like it came out of nowhere! feeling a little desperate

I just found this on my monstera. I believe it’s scales? I’m gonna cut this leaf off. But it’s in different places too and I am not sure what to do. Please help! I’m finding some on my other plants too. 😭

Update: I cut off the leaves that were heavily infested and damaged. Picked off what I could see with tweezers and then sprayed it with this mix. Water, peppermint Castile soap, isopropyl alcohol. Idk exactly how much of each I used maybe a teaspoon or two of soap and alcohol. Filled the rest of my spray bottle with water.

I’m just not sure now how to help my other types of plants. Still learning how to spot them and its damage.

Had these cacti for about 2 months and in the past weeks it’s beent getting more and more yellow. The yellow ones feel similar to the more green ones in firmness and I’ve been giving it a few sprays of water every (other) day. Any ideas?

So the garden in my backyard I am continually having this problem each year where a lot of the vine plants like squash and cucumbers start to develop these gray powdery spots all over the leaves they eventually spread to all the leaves and eventually kill the plants? I had someone say that maybe it was powdery mildew and it could be treated with neem oil but I've tried that a couple years ago and had no luck... Wondering how to prevent this if it's even possible at this point

I recently hung some of my plants (one Scindapsus pictus, a marble queen pothos and a golden pothos)
But I didn’t think about the draft from the AC hitting them (we are currently in a heat wave but the AC unit is only installed about 4/12 months). The AC is blasting virtually all day and maintaining our indoor temperature at 65-70 degrees. The draft hits the middle macrame cord (not sure about it hitting the plant directly).

Will my plants be okay?

An advisor at a plant nursery suggested a specific soil for my monstera. I threw the bag away since I used it all up but I remember the advisor telling me it was a well draining soil mix. The bag said it could be used for zz plants, mondteras etc… Ive noticed (I use a moisture meter) that the soil dries almost immediately. I even used the moisture reader after watering my monstera, the following day, and the meter read that the soil was dry. Out of skepticism I didn’t water my monstera until today (2 days after testing her w the meter), after noticing that she looked a bit droopy and her leaves dry. - I also know that the pot makes a difference so she is in a terracotta pot and in a south facing room (temporarily since her usual spot is in the living room (faces north) but we are blasting the AC bc we are in a heat wave)).

A - is it normal for her to droop?
B - is it normal that her soil dries so rapidly and if so, should I water her more frequently?

My Norfolk has been declining over the past year and it’s only getting worse. This window is a South facing window. The blinds always stay up and there’s also plant lights on the ceiling for some other plants. I’ve tried just keeping the soil constantly moist. I was initially worried about root rot a few months ago so I got a larger planter and let the soil dry a bit and that seemed to help a little. However I started watering regularly again and she’s just completely losing everything. I don’t know what to do and I really don’t want to lose her. Pleas help : (

Technically my mother’s shamrock plant. We were wondering what these white spots could be and if we need to take steps to get rid of them?

New to fishkeeping, I got these plants more than a week ago. I am having issues with my plants turning brown. Any help is appreciated.

I just saw this today when cleaning the leaves. I have checked the whole plants for pest but didn't find any. Other than the brown spot, the leaf is very heathy.

There is browning at the base of these cherry blossom cuttings, could it be rot? I think it's because i sprayed them at night.

I just acquired this plant from my local Home Depot and at the time of purchase it looked pretty healthy. Recently we have been having some heat waves and I noticed that the plant began to change color, but it is not soft so I’m wondering what I should do at this point. Is it dying? I removed it from the sun and it was acclimated and totally fine being in full sun just FYI. I think that because I used a fertilizer on the skin of the Cactus in spray form maybe that’s what did this. I’m really hoping it’s not going to die, but should I try to separate the pups and save what I can? Is it a goner? Thanks in advance for your help!

I’ve had these for 3 years (one is momma the others a few of many babies💕) and for a long time now they’ve been losing lower leaves either to yellowing and drooping (no squishiness or crunchiness though) or sometimes the stem part will go brown at the leaf base and spread to the leaf. I also notice this strange splotchy discoloration (yellow or honestly maybe white even) on some leaves, always the older ones and always around the edges of the leaf. Here is the story of what I’ve tried in the last 1-1.5 years:

1. they were on a table getting only indirect medium to bright light from a south window. I suspected maybe they needed more light, so I moved them to my greenhouse cabinet and a spot in a west window (I have more than the two in these pictures so I’ve tried a few spots). No change. One other was moved to a spot getting indirect light from a west window as well.

2. I thought for a while it was root rot so I repotted in a more well draining homemade mix (definitely has fox farms soil, orchid bark, and perlite but unsure of ratios or additional mix ins like charcoal or worm castings potentially- it’s been a while). I don’t remember having to remove a bunch of rotten roots really, but this was last spring. No change.

3. I also thought maybe the direct sunlight from my west windows or the grow lights in my cabinet were too much as I noticed reddening of some leaf edges. so I’ve moved them to just to the side of the west window where they get more indirect light. Another one is sitting further back in the room getting indirect light from the same window.(Didn’t really expect change here, just worth mentioning for context)

4. I’ve started watering a little more frequently and adding 1/4tsp per gallon of superthrive foliage pro to the water. In case it was root stress from infrequent watering or a nutrient deficiency. This is new as of this spring/early summer.

At this point, I have 3 of these bad bois all experiencing these issues, plus one I gave to my mom last month that also has these issues still. I’ve tried both letting the leaves fall off naturally or trimming when they show these symptoms. I don’t know if this is just normal drop of older leaves, environmental conditions, or pest related. I treat all my plants with systemic granules when I repot just in case, and occasionally microbe lift bmc at a few drops to a gallon for all my plants if I start noticing fungus gnats from new plants still in their settling in phase. It seems like this happens to a lot of lower leaves and if i removed them, the plants would look like leggy sparse little trees. I wish to make them happier and more full and healthy looking than they are. Any guidance and education is very much appreciated❤️

I currently have him on my desk in a south facing room. Although the room gets pretty good lighting, the wall where my desk lies, keeps that area shaded. I noticed that his leaves are stretching in different directions, almost every week. I started to rotate him so he can get more lighting but his branches continue to search for light, I assume. I understood that ZZ plants do well in dark corners so I am wondering if my experience is normal. Thoughts?
