Dioscorea macrostachya: advice needed

Post by Rika » Wed Jul 10, 2019 6:07 pm

Hello fellow plant friends!

I have recently acquired a large Dioscorea macrostachya (mexicana) specimen (30cm) and from what I know it is supposed to grow in summer. As expected for the transport, the vine was completely cut and now I am confused as to what to expect from this plant next. Is it supposed to continue growing and develop a new vine? Should I continue watering it? Or should I consider it an early dormancy?

Your advise would be greatly appreciated!

I would wait for it to show some signs of active growth before watering. It could be right at this moment, but it could also well be something is showing in the autumn. Most of these are winter active. I don't know if they are erratic per individual plant, meaning it could one year grow in summer and the other year in the autumn / winter.

You could give it a one time splash of water to see if that helps things going. And then sit and wait.

I think that Aiko might be confusing this with the winter-growing D. elephantipes from South Africa. D. macrostachya (syn D. mexicana) is as the synonym suggests, a Mexican species and would therefore be expected to grow during summer like the cacti and Crassulaceae from that country. It is possible that a plant of this size might have been dug out from the wild and if so, it would have lost a lot of its roots. So re-establishment could be tricky unless this has already been done at a nursery. I admit to no experience of Mexican species of Dioscorea, but my inclination would be to keep the compost slightly moist into the autumn.

Thank you Terry!
Yes, this being D. macrostachya, I am a bit worried that it was "interrupted" during its growth period. It still had strong looking vines on the pictures before it was shipped to me but they were of course cut for transport. It was delivered with this pot and substrate and it is sitting firmly in it (didn't move an inch during transport) so I think it is either nursery grown or already established since some time.
