A friend asked me about humidity....I know its good for Fig trees correct...????  But I am not sure about growing the fruit properly....any ideas...????  Thank You in Advance !!!!

Humidity might be good for tropical fruits. But figs are native to climates with dry summers. The best fruit will be produced on mature trees in a dry summer climate with limited irrigation. This is how I try to grow figs, nectarine, pluot, and apricot. A water deficit increases sugar and flavor.

Thank you for your response, just was a little confused, I picked up a 3 foot tall black mission last year and they had them in a green house with high humidity.....

So if you live in Florida we have a lot of rain and a lot of humidity but once fall arrives the plants still have hundreds of figs hanging on them that will ripen.  Our humidity is still pretty high but we have passed our rainy season and may get a rain every couple weeks.  Can the humidity itself without rain still cause the problems?

Humidity by itself can cause splitting and fruit rot but usually it's a combination of rain and humidity. Together they also increase the water content of the fruit. Some people may like the watery figs but I prefer mine drier.

Armando and steve, I am wondering the same thing.  I'm within days of buying my new greenhouse.  I will keep many figs inside.  Just curious if I need to add a humidifier to keep the air a little moist.  My new GH will be 12x24.  

 No.

Humidifier would be the last thing I'd think about buying. And I'm in a much drier environment than you. Same advice for figs or any other fruit I grow.

Ok, so, don't install a humidifier.  Great!  I won't.  This GH will have about 6hrs of direct sunlight.  My plan is to place my heat hungry trees in there like Black Jack, Tx Blue Giant, Black SPanish, Black Maderia and a few others.  I also have a small 6x8 GH.  That dude is in direct sunlight.  I plan on covering it with shade cloth this year and using it too.  Thanks for all your help.

Hi Snaglpus,
you don't need a humidifier. One bucket (or more depending on size of the GH) of water inside the greenhouse on a sunny spot will be enough .
I wouldn't keep the air too dry so the bucket is what I would do - and what I do when I have young potted trees in the GH . It helps the leaves not getting cooked IMO .
Humidity will help the trees grow faster, and humidity in the air will act like rain at night when the temps drop and humidity turns back to water.
I already mentioned it, but once more : it seems to me that my figtrees benefit from water falling on the stems - like washing them - Do it in the morning or evening not at noon .

In my Zone7, humidity does naturally drop from July to September; so if you live in a more humid environment you'll need to adapt to your locales .
