Sick TBM

Recommended Posts

A while ago I pounced on an eBay sale, mature TBM plants for around $50 BIN, delivered. The plant arrived, but as soon as I divided and replanted, the segments began to wither and wrinkle, as pictured. After a month or so in fresh pots they showed no signs of recovery. I became concerned that these plants might have been exposed to a poison (prior to being listed on eBay), and so am reluctant to put them to use in my medicine garden. Any thoughts?

thats just root rot. cut off the healthy segments, leave them not planted until they are dry and calloused and put out some new roots, then replant them in a couple months with less water / fert.

Is that a piece of lava rock I spy there? Because of its tendency to retain water, it can cause issues (rot, algae, etc.) with succulents of all types whether it's in the soil as an additive or if used as a top dressing. It's definitely one to watch!

Good to know. I've often used scoria in the bottom of pots for drainage, or as top dressing, never had any issues with it before. But will definitely take that advice on board.

Will do, thanks. This is the only cactus I've come across that didn't respond to TLC -- if anything, it showed signs of rapid deterioration from the moment I received it.

Agreed.

To speed up the process in situations like this, I like to get a small finger nail sized paint brush and brush on some clonex to the base to promote speedy root formation.
