Unexpected Keiki

[gravotrope]

I have a few different dendrobium species, and so far I've known them to love a high airflow with humidity down to 50 or even a little drier depending on the species, they are burly plants and as long as you have healthy canes, you will eventually have healthy keikis, even if there are no roots on a division of a few canes. they may need to rest before resuming growth, but I would say they don't need more than a month if you can find a way to give them some more light. I'm not sure you should be using willow water, since you can end up culturing bacteria from your hands into it. also, the salicin in the water seems like more of an immune boost to orchids than a root stimulant, though I have seen uncoated aspirin influence a flower spike - by stopping it. it later resumed growth after I stopped dosing the plant and became a 3.5-4 ft branched spike.

you should treat it once with garlic water or weak physan to 'clean it' and then basically leave it alone until you have more light for it or you see it growing

There are two substances found in the willow tree that enhance root growth, Salicylic acid and Indolebutyric acid. When you make willow water, both these acids leach into the water and provide beneficial effects for your plants. They help your plants fight off bacteria and fungi, giving them a better chance to survive, also help speed up the rooting process.

Hello and thank you Ovanoshio and Nexogen.

For the past two months I was keeping the two orchids under some 1.32 gallons (5 liters) canisters which I misted twice a day, sometimes uncovering the orchids during the night. This I guess helped the starting of keikis but I don`t know why they don`t develop anymore. I am keeping the dendrobiums two days (sometimes also two nights) under the humidifying bells and one day without. Hope this helps.

Recently (~2 days ago) I have been using some diluted-almost-as-recommended orchid fertilizer (maybe not very diluted) sprayed with a syringe at the base of the canes, targeting their roots. Hope this also helps.

Now, regarding the wiping willow water, it`s autumn right now in the northern hemisphere, therefore also in Romania, and I can`t make wiping willow water anymore. I have made some a while ago (~3-4 months, a full mug of 1cm green branch tips in 1 liter of boiling water) and I am keeping it refrigerated (not frozen) in a Grolsch beer bottle (very good sealing stopper). Should I use this as well?

It seems that the canes don`t throw any roots at all, nor the keikis.

I have two flower spikes that have very small keikis on them. One had roots about 1/2 inch long or smaller, with another keiki above it.. The other keike has very tiny roots and above it the flower spike turns in to two spikes with flower buds on it. It isn't developing roots as fast. I am tempted to cut the spikes above it off to see if it develops roots faster. Also, should I put a drop of fertilizer in the water, fish emulsion or Grow More ( I have all 4 kinds)?

I also have stalled keikis on Dendrobiums. I assume that because it is winter, not growing season, that is why they are not progressing now. I'm hoping when spring growth starts, the keikis will also start growing again.

I have mine in a garden window in my kitchen. It is probably 60-65 degrees. Should I move them to a warmer place, not sure where that is in my house, I keep the thermostats low.
