It's in a mixture of orchid bark, cactus soil and perlite. And I could well be, the person I got it from said it flowered randomly.

Pls. touch the soil & rootball & tell us-- are they hard to your touch?

Sounds like a drainage problem, that the rootball has become hard & compact, not letting water penetrate the soil into the roots & ultimately water isn't getting to the leaves.

I suggest taking several cuttings just in case.

Ooo and it's in a standard plastic within a terracotta drip pot, but I don't let it sit in water or anything :)

Yeah thee rootball is hard, I did my best when I repotted it but it was very root bound, it's in fresh soil though so that isn't compacted.

I'm confused if this is causing the leaf issue as the leaves are going soft, wouldn't they be going dry if it was lack of water?

Thanks! :)

Also, I just had another look properly at the leaf shape, and I agree it is probably a christmas cactus not an easter, I was just confused as it is getting buds now :

If the rootball is still hard, the plant can't drink, even if the new soil around it is not compacted.

Sorry, but I think if mine, I'd take it all apart (after taking cuttings I suggested). Drop the cuttings you take into a glass of water, just 1 inch or 2 deep. They should perk up in a day or 2.

I'd unpot it & remove ALL the old mix, even if you have to soak it first & then break the rootball apart w/ your fingers. Any damage done to the roots while doing this is not a problem. The way it is now, it will eventually die of thirst. Seems like the old hardened off soil is strangling the roots &/or preventing them from taking up water.

Sorry, but I doubt this will improve w/out the intervention I'm suggesting.

Leaf (segment) shape is what distinguishes these plants btwn Easter, Xmas & Thanksgiving, not the time of year they bloom, which can be made to vary by manipulating its care & culture.

Here's my Thanksgiving Cactus, w/ its sharp, jagged edges.

Your plant isn't dried out YET, but I believe the dry spots & limpish leaves are indications the plant is reabsorbing the water in the leaves since it can't get more from the roots.

If you want to reflect on this a bit, I suggest the following.

Take a pencil & poke holes down into the mix between sections of the plant, at least 1/2 dozen or so, then water down into the holes you've made. That will ensure water getting down into your rootball & the central core of the plant. That should cause a marked improvement w/in 2 days I'd guess.
