Help with 2 cacti looking very ill!
Hello All, I'm a self confessed cacti & succulent killer looking for some guidance to quit my murderous ways! I'm hopeful one day I'll be reformed and building greenhouses until my heart's content. Until then, could I ask for some help please?
I've attached photos so y'all can have a good look at my 2 sad fellas, I really haven't a clue what I've done or haven't done to them to make them so ill. They're suffering from what I can tell, two different problems. But as I say, I really don't know. Both became ill early on, so I brought them home thinking they looked healthy and shortly thereafter I managed to mangle them. They're still in their original soil and pots, living on a windowsill indoors. They receive plenty of sun, little water as the UK is quite rainy on the best of days.
I do not over water, that I can say for certain. If anything, underwater and have administered cinnamon to the soil on one of them as I thought at one stage maybe there was too much moisture in the air (seriously I must have been having a day of backwards logic when I did that!). Lots of sun, as much as the UK offers, and I even wrapped the sides of the container (pot) in bubble wrap to try & keep them warm winter past. No freezing or frost on either of them throughout the winter.
I'd be great at caring for them, if I knew what I was doing that was wrong. Also what to do that's right. Any and all advice welcome, thanks so much in advance.
Should I repot with better soil? Add nutrients to current soil? Water more often? Less often?
