Your plant looks good. It is not hard to grow once you learn what it wants.

This species has a particular growth and flowering pattern. It does not seem to be tied to the seasons in North America.

It grows for a while. Then it sits for a while. Then the leaves fall off completely. Then it blooms from the leafless pseudobulbs. It can bloom many times from the same pseudobulbs, so do not divide the plant and do not throw away old pseudobulbs.

Then after blooming it rests for a variable while. Then it starts growing again.

There is good information on this plant here on Orchid Board:
http://www.orchidboard.com/community...ium-bloom.html

It may burn in direct sun. Move it to bright indirect light.

It likes to be evenly moist all year with no water rest period. Many of us check the moisture almost every day, and keep the top of the medium just moist to moist. Many like to use a spray bottle to spray only the medium, in order to keep water off the plant.

It may not want much fertilizer. People grow it successfully with no fertilizer. Some give just a little fertilizer one to three times per year. Some give more fertilizer.

My first step would be to take a look (gently) at the roots. Any white roots with green growing tips are precious. In the beginning of the growing year, (spring usually) dendrobiums are usually very thirsty plants and put out new growth at the base. Do you see any such growth? First get a healthy plant going, and then later, flowers will come.

Dendrobiums, unless other wise stated like a lot of light. I have mine outside on warm days even towards the end of the winter. In Canada, I am not sure you have that option, but there are small portable greenhouses, or fish tanks with heat mats or lamps in case you are in an apartment. Light and water lead to growth.

Indirect light is the kind of shade you find under a big tree outside. Even inside near a window is not enough light. Maybe for phals or paphs, but you get into Dendrobiums and Cattleyas and you are talking nearly full light.

Things to check out. Do you have soft water? That will kill an orchid. Is it sitting on a heat vent? Is it too close to the window?

Raising orchids is like a detective show. Many people find it fascinating because it is just not "passive."

Thanks estacion and optimist, its very helpful the information and the link. I think that i let mine too dry before water. I will mist the plant everyday as you say :)

I don't know. Some of those might be alive. I would try to keep it evenly moist for a week or two, and look again.

Ok 👍

Are the psb still green?

Here my plant this morning I lost 3 more leavesAttachment 119833

It still looks OK to me. Remember this plant loses all of its leaves some time after growths mature. Then it rests for a while with no leaves. The old pseudobulbs will not form leaves after the first set; leaves are only on the newest pseudobulbs.

Your pseudobulbs look mature. Too much sun may have made them fall off faster than normal, but I think your plant is still OK.
