I've had cacti for pretty much all my life and had one, in particular, for 40 years before it finally popped its spiky clogs a couple of years ago (I think I overwatered it....).
Since then, I've had a few more with varying success and seem to find it hard to keep them alive and healthy.
At the moment, I have what I think is an Aloe Juvenna (see pics - mug included for scale!), which I know is technically a succulent, not a cactus, but anyway, it's not looking too happy.
I bought it from a garden centre about 6 months ago, and after a while, carefully repotted it using cactus compost, in an earthenware double-pot - ie the inner pot (brown) has a drainage hole, and it sits in the outer pot (beige) which can collect the little bit of drained water at the bottom, if necessary.
I thought this would be a perfect solution to the problem of overwatering or water not being able to drain freely enough.
The plant has been sitting on my coffee table near to a patio door which, during this fine weather, is getting a lot of sun in the afternoons, so I'm wondering if it isn't liking that?
It seems less 'plump' than it used to, as if it's shrivelling up slightly, and there are dead brown spots on it.
I've moved it to an area that doesn't get the direct sun, to see if that will help.
I've hardly been watering it, and gave it a little bit last week, with some cactus feed, and the excess drained off into the outer pot successfully.
Any advice please? I've lost all confidence in keeping cacti/succulents since a few have died on me recently... :(
