Dendrobium aggregatum question
Comments (14)You don't really 'see' spider mites, you see the evidence of their existence. The yellowing of the foliage will not be the even, sickly yellow of overwatering it will be more mottled. The surface of the foliage will be matte (dull) rather than smooth. You should look carefully 'under' the leaves where you may see webs. Still, mites or not, light will help. It will give the dend the energy it needs to repair whatever ails it. Just took a look at the o.p.'s zone information. Zone 5. Hmmm. I can't see Zone 5 this time of year, even indoors, generating the kind of temps that would allow an infestation of anything to overcome the defenses of a reasonably healthy orchid. The activity of insect pests is directly proportional to the ambient temp. At higher ambients they can really increase their numbers exponentially and take down even strong plants. At household ambients that shouldn't happen unless the plant is already weakened for some other reason, like a lack of good light. H...See MoreDend. Aggregatum
Comments (13)Den. kingianum can stand temps down to about zero. C. Same for all the other toughies but not the temps in the frozen north. (Where the real orchid growers live). Forget all this bone dry stuff, it is twaddle! Just think drier! The climate here is east coast erratic. My last experiment with totally dry was with Stenoglottis longifolia. Needless to say it died. The replacement plant is going to spend winter out in the shade-house getting what rain that falls plus top up by me in really dry periods. While i'm raving on....here is a picture of the hated banana herb growing next door. Always looks straggly and it is like those casper milk toasts of the orchid world Phalaenopsis. Any suggestion of frost and it is cactus! The coldest it has ever got in this micro-climate is about 1C....See MoreDendrobium: fast new growth but old canes wilting/ is it Nobile?
Comments (11)The problem with Hard-Cane Dendrobiums is winter. Where are you going to place some of these monsters with three foot canes? One grew to 6 foot. Needless to say i no longer have it. As for Dendrobium Hollywood. Not registered in the RHS register of hybrids so who knows what is in the ancestry. Some are easier to grow than others. If you are a Novice you should be trying to grow what is easy in New York. Just taking a break from the local Society winter show. There are 200 plants in the display. There is ONE Vanda and nil Hard-cane dendrobiums. Anyway, ask the locals what is easy in New York and follow the fundamentals for things such as Cattleyas and Oncidiums forget about culture in Vases....See MoreWinter rest or not for Dendrobium aggregatum?
Comments (8)I hope this helps Bill) Watering: The watering may be the most crucial element to success with these orchids. Their native conditions are fairly wet during the late spring, summer and early fall. Rainfall can be quite heavy for a few months, but it tapers off in the late fall, and winter months are fairly dry. Water the plants regularly when they are actively growing; mounted plants can be watered daily if air circulation is good. When the new pseudobulbs have matured in the fall, gradually reduce watering, and allow the plant to dry between waterings. Winter Rest: Den. aggregatum requires a winter rest period. For a few months (Nov-Jan), the plant should be exposed to 50-60 degree temperatures at night with slightly warmer days. Watering should be gradually withdrawn and fertilising completely stopped. Plants should be watered very sparingly throughout the rest period if the pseudobulbs show extensive shrivelling. Some shrinkage should not be alarming and plants may be partially deciduous. Sun exposure should remain the same from the growth period through the rest period in order to ensure spring blooms and growth....See Morearthurm2015
