Around how long does dendrobium phalaenopsis take to bloom in tropical climate?

I live in the Philippines which is a tropical country, and my searches say that most flowering plants including orchids bloom from late summer to fall. I guess I won't find that information useful to me. My plants send new growth even before flowering, so not sure when they will bloom. If anyone can give additional tips, please do. Thanks in advance to anyone who answers.

Hi there! I'm from P.I. too... Dendrobium phalaenopsis are very prolific bloomers, however the time when will your plant will bloom next is relative to the current health of your plant. If it is fairly healthy and is in a sunny position, a spike could be coming out in the next few weeks... however if your plant is quite thin, an application of multipurpose orchid fertilizer such as Gaviota or Siam would help! Btw, in my case orchids have no seasons, they bloom year round, however the peak is always in summer : )

Happy Growing
Reply:These orchids will start spikes after the current season's growth has matured. Usually in the fall here in the US.

They will also produce spikes on older canes.

Light source for dendrobium orchid?


I bought a plant section for a Dendrobium orchid Nobile - leaves and stalks with roots, no flowers.

Anyway, the root are growing but I notice that whenever I put it beside a window, instead of standing upright, the whole thing bends sideways to face the window, and it looks really dumb!

Do they have to recieve lighting directly from above? If so, is artificial lighting good enough?


Light source for dendrobium orchid?
dendro need 40/50%sun light the whole day .near the window without curtain will also do .vitamin B is there fatilizer if you have tablets place one on top of root every month . do not cut the old sterm.change root cover with coconut shell every six months
Reply:Light requirements

Dendrobiums like good light at all times but they should not be kept in full sun or they may scorch. Keep them in the brightest position during the winter months to help ripen the current years stems, called canes
Reply:Nobiles are somewhat difficult-nitrogen at the wrong time will get you kikis and no blooms.Might try another species.Also try contacting Yamamato Orchids in Hawaii for some cultural advice. And if your going to try artifical lighting you will do best with a hid type. Best of luck!

What are the special feature that Delonix regia and Dendrobium have to ensure the success of their fertilisati

Dendrobium is orchid's scientific name

Delonix regia's common name is peacock flower

What are the special feature that Delonix regia and Dendrobium have to ensure the success of their fertilisati
Delonix regia is pollinated by bees and birds depending on geographical location. It has some interesting adaptations to attract pollinators. The most obvious is that it produces generous amounts of nectar and pollen, which is actually relatively uncommon as making these uses a lot of energy, so this guarantees that it will be visited by pollinators. But attracting the pollinators is only the start! Delonix's red flowers are an attractive colour to birds, and they have thickened organs at the base of the flower (where seeds are produced) to protect them from damage by birds. The long nectar tunnel also ensures that birds have to put their head well into the flower and so get a good coating of pollen, to get to the nectar. Delonix also has special adaptations for bees and slightly changes flower colour as they age - bees can detect this and save time by only visiting young flowers which contain more nectar - this also benefits the plant because young flowers are more fertile than older flowers so it ensures that flowers are pollinated while young. The plant keeps older flowers as the more flowers there are the more attractive it is to bird pollinators. A pretty clever plant I think! :)

Dendrobium: The pollination biology of all orchids is a v interesting and specialist subject and I'm not an expert! Dendrobium is a large group of orchids and I do know that one of the strategies that they employ to ensure fertilisation is to have long flower life (several weeks), but the flowers wilt almost right after pollination - it's expensive to keep flowers alive so they do so for as long as is needed but no more, in contrast to other plants that usually have a set floral life span.

Hope that helps xx

"I need a help..." Delonix Regia and Dendrobium flower...?

Family- Leguminosae ; Sub-family- Caesalpineae.

Type of Ovary-- Monocarpellary , superior, unilocular , with Parietal placentation. Fruit is a legume or pod.

Symmetry of flower-- Bilaterally symmetrical or zygomorphic flowers.

Success of fertilization ? - It is ensured once pollination is accomplished.

It is insect pollinated and they are attracted by large showy flowers.

Family-- Orchidaceae of Monocot plants

Type of ovary- Tricarpellary , syncarpous, inferior , unilocular , with parietal placentation.

Fruit is a capsule with a hge number of small dust like seeds(Hence the entire group of orchids is called ' microspermae'

here spermos means seeds and not ususal sperms that everybody knows, ( Remember Angiosperms?).

Symmetry of flowers-- Bilaterally symmetrical or Zygomorphic.

Success of fertilization is ensured by nature once pollination is accomplished.

Pollination is by insects that are attracted by showy flowers.

How should I care for my Dendrobium orchid after the flowers have faded?

I have a nobile Dendrobium orchid that has flowers which are fading. There's a tall stalk with nothing but flowers that grow from the sides of the stalk. The stalk has no leaves, only flowers. At the base are 2 small suckers with leaves. I am concerned about what to do with the main stalk after all the flowers are gone. It will be completely bare. Should I cut it or what. I would greatly appreciate any advice from someone with experience growing nobile Dendrobiums. Thank you.

How should I care for my Dendrobium orchid after the flowers have faded?
Give it a while to shrivel back. Then cut it to live growth, dab it with something antiseptic (like sulpher flowers) and let it do its thing. They are pretty hard to kill.
Reply:NOOOO!!! Some species of dendrobium are deciduous when fully mature. They will lose all leaves from their stalks, but they will still flower. Unless the stalk clearly starts to die (turns yellow/brown), don't cut it. Report It

Reply:Yeah, I looked it up--dendrobium nobiles lose their leaves. Also, we were using the incorrect terminology. The stalks are called "canes". The word "stalk" refers to the things the flowers are directly attached to. So, what you have is a leafless cane with multiple flower stalks coming off of it. Report It

Reply:Here are some sites for your perusal.
Reply:I would suggest going on line there are plenty of sites to help you transplant and take care of orchids.
Reply:When the suckers are 3 inches long and have at least 10 roots each about 1 inch long, cut them off below the roots and put them in their own pots and care for them as usual. I don't know if the big one can be saved. Bye! :)

Why will my Dendrobium orchid not bloom?

I have several orchids in my home. The oldest and my first purchase was an Dendrobium. It is approx 4 years old and has not had any reblooms. It has a TON of new growth. All of the others are budding and have bloomed each spring, but not this one... What can I do or what am I doing wrong? I've researched websites for answers, but no luck there.

Please help my orchid. Desperate in Texas!

Why will my Dendrobium orchid not bloom?
put it where there is moire 2 to 1
Reply:Sorry, I am not sure that I understand your answer. What exactly is moire? Report It

Reply:Try using fertilizer, if you don't already. A 2-2-4 fertilizer is good for regular weekly waterings. When you see a new plant starting, switch to a blooming fertilizer, such as Dyna-Bloom, that has a little higher phosphorus. This promotes blooming by giving the plant the nutrients it needs at the time the buds would set in the orchid, which happens months before it actually blooms.

Good luck!

Dendrobium questions?

How can I split or depot my dendrobium and repot it into several bulbs? Do I just split the dendrobium bulbs into individual bulbs and repot it? There are around six to eight bulbs in a 2inch pot. I think I need to repot it as the roots and bulbs are spilling out of the pot. But I am afraid of killing the dendrobiums.

Once I cut the bulbs, is there a solution I need to keep them into prior to repotting? There is no pictorial guide when I searched the web. I am a newbie in trying to repot my dendrobiums.

Dendrobium questions?
Knock it out of it's pot and use a strong sharp knife to divide the clump in two by slicing between canes.

Repot tightly in fresh orchid mix to the same level as they are growing (don't bury any part of the stems). Use small pots, about an inch larger than the cuttings. If it makes you feel better, you could dust the cuts with fungicide, but it is not necessary.

See source for information on growing orchids in your home.
Reply:yes you can. cut the bulbs into individual bulbs using a sterilized knife. then you can place the bulbs in a hydoregen peroxide solution. clean the bulbs in running water and remove dead roots and other soil or potting materials. place the individual bulbs in tight cocofiber pots with moss and charcoal bits. bind tightly with fiber rope to hold the cocofiber and moss/charcoal together.
