Den Nobile - Orchid Board

rbarata · #1 10-11-2015, 05:30 PM

My Den Nobile is growing a new cane (sorry, no pics)...it's still very tiny, maybe 1 cm long...my question is: is it supposed to be happening now? With the cold, it should be entering the rest period, shouldn't it?

Maybe this is related with my first application of akerne's Rain Mix fertilizer, first time one week ago...

Thanks

It can grow new growth anytime. Just do what your plants tells you to do. If it putting out new growth. Then start fertilizing.

I always thought that, when an orchid enters the rest period, should not be fertilized but I guess this is a sign that it might be too soon for it.

Don't judge the rest period by the calendar. It starts when your orchid stops growing.

I suspect this new cane will be like other small ones he has, somehow started to develop but then stopped.

Today, looking closely when watering, I noticed it is not a new cane...it's a thick root with an extremely long green tip.
Considering the harsh treatment I gave it to eliminate an heavy infestation of mealy bugs, this is a very good sign.

Isn't it interssting that when we treat it poorly, it perform even better? Anyways, good to hear that you got good root systems growing.

It is rather late for a new cane to start and this can happen most often when you buy one in flower out of season as nurseries can manipulate them to flower about any time of the year.

Once it adapts to your local weather conditions, it will get back in cycle.

For future reference, for nobile and related hybrids, you want to stop fertilizing by early or mid summer.
This is when the new canes are about almost mature but not yet plumped up all the way.

Fertilizing later than this period can results in very poor flower the following spring.

Happy growing!

I think you need to look at your temps through the year. In the summer here, it is very hot, and nothing much wants to grow They just use up their sugar reserves. In the fall, the process of growth starts again. My Dend Nobile has 7 new growths, some only one inch tall. Iwill keep on shuttling it in and out. Giving it sun, if only for a few hours per day. My Dend Nobile never shut down last year, and never lost its leaves even. I wonder how other "southern" type growers fare?

I'm going to find out. Will report back.

I bought a primary cross Dendrobium primulinum 'Magic' AM/AOS x D. loddigesii 'Gilbert' from Carter & Holmes early this summer. It is mounted on tree fern but this year's growth dangles far past the mount. It finished growing a few weeks ago. These two species appear to be in the nobile group and need a dry, cool winter rest. But, it won't be cool for another month here. I didn't know I was supposed to stop fertilizing by mid-summer. I need to find out what the plant thinks is mid-summer. I've been spraying its mount daily with MSU in rainwater at about 40PPM nitrogen. I will stop the fertilizer now and move it outside where it will get cooler nights and more light. I'll let it get dry for a couple of days between waterings, rather than the previous twice daily wet/dry cycle it's been on. Then when we get really cool weather I'll cut back on watering even more.

I also have my new arrivals. 2 are in bud from Carmela's, flowering on new growth, so I figure they're evergreen D. phal hybrids. That means year-round warmth and watering from what I've read.

I also just got D. moniliforme from Andy's Orchids. It's also completed its growth. Reading shows this likes cooler winters, too, and reduced watering and fertilizing but not drying out.
