What problem with my dendrobium? Help me

Hi Everybody.
I just start and bought a dendrobium in blomming ---on 03/2009. But after go home 02 day, all flower drop down .
Now it blooming back with 02 spike but the big one drop down yesterday and another one seem like will ..."go" to.
The plant grown good and fast, I used better-grown orchid fertilizer 20.14.13 follow instruction and same
brand bloom booster 11.35.15



Does it have any problem ? And please help me to fix > Thanks

Did the spike just break off? Or did it get chewed off by a bug?

very strange, do you have pets in the house?

Hi Chaud,
How often are you using the fertilizer? Maybe to high nitrogen content or mixed to strong. Nitrogen is good for the leaves, but not always for the blooms. This is what I was taught many years ago - if I am wrong, somebody please correct me. Thanks...

Also. do you have the air conditioning on? Might be that the plant is to cold. Or, how different is the temperature in your house from the conditions it was growing in where you bought it? Just a thought. I also notice that where the spike came from there is a plant tie which also has a portion of the leaf. Is there water or moisture trapped as it may have caused rot at the base of the spike. Hope some of this might help, it is a lovely plant.

I don't know much, so take this for whatever it's worth, and then listen to the more experienced people here.

I think you're using too strong, and too much fertilizer. Your orchids should be fed, but the formula is weakly, weekly. I only use about an eighth of a teaspoon, mixed in with a full pitcher of water.

And this may be a long shot, but I see bananas next to your orchid? Not sure if this is normal at your house, or just where you chose to take the photos, but I've been told to never keep fresh fruit near orchids, as the gasses the fruit emits can do severe damage to the orchids.

Good luck with your growing. You're going to do just fine!!

Thanks yours help . I grown it outdoor on verandah and under shade of a big tree, plant seat above a small moisture tray( sure the bottom pot not touch water)> myarea temperature this time 90-97oF(weather chanel TV) .Too hot so I misted every morning before go to work with 1/8 strengh 20.14.13 (1/2 teaspoon in 2 gallon water). The spike just break off at the base .
Thanks people gave me lot help idea, now will I use more 11.35.15 and reduce frequenly water and fetilizer(does use 11.35.15 every two time plant fertilized a good idea?) ? . Also I read some where about prevent pest, decease and virus with neem oil How about it ? Can I use it as a security way for my orchid ? I much appreciated

Hi Chaud, do not reduce water, but do reduce fertilizer. feed only 1 time a week or every 2 week. To much fertilizer I think. The plant will need frequent watering in that heat 30 - 35C. Give them a good watering every morning, making sure the planting medium is wet right through the pot. Hope this helps.
