Problematic MMM 'Witchcraft', new questions

[tjselwyn]

A few months ago I posted about a Monnierara MM 'Witchcraft' I'd received that was in less than ideal condition; the existing bulbs were thin and already wrinkling, and the one new growth it had at that point was still tiny.

Since then, it's produced two more growths, but none of the three have come to much (the largest is about four inches tall, including leaves), and as we're getting towards the end of summer, I assume none of them are going to mature. In addition, the older bulbs are now extremely wrinkled, and the largest, which the new growths are attached to, is beginning to yellow from the base upwards.

I don't know what to do with this now. Is there any way that I can coax it, or some part of it, to survive and possibly produce proper, strong growths in the future? I left the old roots on the original plant, but they've been dried out for three months so I don't know whether they're viable at all (I'd assume not). Two of the new growths have roots, but unfortunately, because of the medium I've potted it in, I don't know how long they are.

Any advice would be very welcome!

I would water and fertilize heavily, and give lots of light.

I would soak those old roots still attached the bulb and see if they can provide some water to the rest of the plant. What other conditions are providing, specifically light and temp? Are the root tips on the new growths still green?

Thanks, both, for your replies.

It's indoors, at a west-facing window, behind sheer blinds. I haven't used artificial lights over the summer, so it's been subjected to the randomness of UK natural lighting, although it's been mostly clear and strong for the last few weeks.

Temperatures over the last few weeks have varied between, I'd say, 25 and 35 degrees C (77–95F). It's now cooled down a lot, so I'd imagine it'll be low to mid 20s for the next few weeks.

The only root tip I can see, on the mid-sized growth, is green, but I'm fairly sure it hasn't actually grown at all for quite some time - possibly a month or more.

Ah, I suspect the lack of light is causing it to not grow. This is a group that would do best grown with zero shade (or supplemented with lights) at your latitude.

Ahh, ok. Well, now I know - good lesson for the future. Thanks for your input!
