Question

My orchids look very healthy with lots of green foilage...but no blooms. Why?

Answer 1

The usual culprit behind a healthy orchid not blooming on schedule is not enough light. If the leaves are a rich, deep, lush green, try upping the light a bit. It may take another cycle to bloom (a few months to a year, depending on the orchid). Also, the most common orchids, Moth Orchids or Phalaenopsis only bloom once per year (though they make up for it by staying in bloom for several months at a time).

Answer 2

If its Aranda and Arachnis (also Mokara , some of them) require full sun of the tropic. And if closer than 6 inches apart , will race one another for the Sun , while witholding flowers.



If Cattleya , too humid. No pronounced dry season. Cattleya need dry wind to bloom. Wind ! Not ventilation.



,, if lumpsum ,, maybe your photoperiod is too short.



,, short day flowers in orchids are usually grown long day. Then shorten to time the flower. Also when you put short day , drop the temperature say for 1 week then bring back up. Ascocentrum especially.



Chrysanthemum you can grow straight in short day. The primodia starts very early. Orchids can abort primodia.



,, For Spatoglotis orchid , add clay , or laterite ,, and make it a little dry. Orchids need to "shift gear" from green growth to bloom. You don't stop the green flush it won't bloom.



,, How many elements are your full fertilizer spectrum ?

,, Maybe your greenhouse is too warm. Or the temperature is too even throughout the year.

,, A 10 minute freezing can put the Dendrobium crumenatum and the Doritis in to flower.



,, Is your Doritaenopsis and Phalaenopsis spiking (new plantlets?) That's where the flowers went.



,, use temperature stress.

Healthy orchards and vines will not bare fruit. Plants need stress. That stress causes them to have to reproduce. It also causes them to produce very sweet fruit. This is done with grape vines in order to produce better fruit and more desirable wines. Find out what soil will cause your orchard to bloom. Maybe certain fertilizers and pruning the tree back will cause it to bare fruit. By pruning, it causes new growth and stress. This will cause it to bloom flowers and fruit.

The other problem is that the blooms get blown off and then you have less fruit. It is better to prune them back and get less but better fruit.

I have done this in various small agricultural ventures with great success. By the way it boils down to Herbert Spencer's first dynamic. Survive. All species when endangered will procreate in order to survive. The harder it is the more they try and the sweeter the result. Why do you think they play the blues? People do it too. That's why in the poorest areas where child fatality is high families have 12 children. But where it is wealthy we see families with 1 to 2 children. Survive! That's why your orchards are bearing no fruit.

Answer 4

There are as many answers to this as there are orchids. What kind are they?

Answer 5

there is no fertiliser o any flowering agents like bee o butterfly to help it to bloom....try plant some other plants as well it help to bloom faster

Answer 6

Proper fertalizer is a must!

Answer 7

More humidity is needed ?

Answer 8

cause they dont like you



hehe



just kidding
