Hi, I have noticed that my succulents "branches" are turning yellow and shriveling up and then falling off. I wonder if it may be an iron deficiency but I need help.
My cactus is looking bad, it has brown type stuff and it looks like it is melding or dying I'm not sure. Also need help if you don't mind. It gets lots of sun and I don't water them often because I know they do not like too much water. I also thought it may need fertilizer but that may have to wait until late spring/summer.

Are you sure some critter isn't munching on them?

Hi,I have an unusual plant I gréw from a cutting someone gave me a couple of years ago here in Maine. I originally thought it was a variety of Christmas cactus but now I think it's some type of weberocereus. I haven't cracked the code to growing it but see that it hangs in there growing despite now having a few black edged leaves that seem to creep and some trails of parasitic creep(spiders)?. Is it just that now in a very cold winter the plant is flailing? Or it has mites? I've sprayed it with neem oil frequently and misted it with water, and kept it under grow lights but it now seems dormant so I almost never water it but it's not shriveling up. Does anyone have hints on this mysterious plant? Thanks!

@Mimicoco2, could you please start a new thread with your question? It gets very confusing when we try to answer too many people in one thread. Thank You! Remember to add some photos.

@Cassiemccallum, The plant on the right is a Euporbia lactea 'Cristata' grafted to Euphorbia trigona (or something similar). It does look like physical damage. These plants are very top heavy and the damage is on the 'down-hill' side. If the plant tipped over, and the little spines on the edges were injured, this sort of damage would result. It won't hurt the plant, except aesthetically. Try putting the pot into a larger heavier pot so it isn't as tippy.

Don't fertilize until your plants are in active growth, then mix the fertilizer at 1/4 the recommended strength. Don't repot.
