The only Dendro I have that is deciduous is anasmum (superbum). I withohold all water (totally) from Oct 31 (Halloween) till new shoots appear in spring (usually Feb 1st or so). As far as I know, all deciduous Dendros have a dry spell, usually corresponding to the dry seaon in the area they are from.
Ha, while I've been devoting my time, following this thread, and reading all the posts, I failed to notice my D. anosmum has several buds close to opening. I will try to upload a picture next week when they open. Can't wait for a whiff of the sweet raspberry scent.
In a previous post, I said that my D. anosmum were still sleeping. What I thought was my D. anosmum is really a D. secundum alba, which has just the first hint of buds near the tips of the canes.
We had Bob Hatos speak at one of the local orchid society meetings here. He is a local expert on these plants and he said not to water until you noticed the new growths were coming up. Once that has start then it is safe toresume watering. He also said the key to good blooming was to fertilize and water substantially during the growing period. Hope this helps.
My anosum has 3 old canes covered in keikis. What's the best thing to do with these, pot them individually or put them all into a large community pot?
TIA.
Keep in mind I did this with a nobile hybrid, but I was in the same situation a while ago and I mounted the entire pulb on a piece of cork. Great way to establish a mount quickly. Seeing you live in an area capable of hosting anosmum outdoor year round I would even think of mounting the bulb to a tree and within a few years you'll have a beautiful specimen.
