Finding the roots were very rotten sometime in June, I decided to try a modified version of "spag and bag" method I had heard off - I suspended it in an empty plastic container with some moss and pebbles at the bottom. The moss to keep the environment in the container humid (it's SO windy on our balcony) and the pebbles to weigh it down so it didn't get blown down with each puff of wind!
I'm glad to report that it hasn't died and there is some new growth appearing... I just removed all the old roots which were dried out as I was a bit worried they might get in the way of the new growth. I also split the section with new growth off from the other section in the hope that it might fare better.
The section with new roots and what looks like 2 new pseudobulbs |
The section with no new growth |
The 2 sections were originally one plant but I decided to separate them |
I was a bit worried that the new roots were drying out too much after removing the old roots though and now I have put it in a pot with bark and clay pellets but I'm also worried that that will be too damp!
"Whatever the type (of dendrobium), it is important that when the season's growth is complete, water should be withheld. Plants that are watered while resting face the danger of losing their domant root system of suffering damage to the eyes at the base of the plant; this will in turn upset future growth as the potential flower buds along the stem will produce small plantlets, known as keikis, instead of flowers..... To prevent the keikis from growing, the plants must be kept dry in winter."
Wish I had known this early - it would have saved a number of dendrobiums I have killed!
