Almost every citrus tree that I am growing, has started their spring flush and bloom. I plan on spraying most of them with Gibberellic Acid when they come into full bloom - Millet (728

i have a Meyer lemon that is blooming, and has been for a while now. the cold must be slowing it down some and have been protectting it during the really cold nights. i assume it is the fall bloom. wondering how this will affect the spring bloom. which usually comes in march/April.

That is a 3 months ahead of my citrus in local (non-heated) conditions.

Early blooming is a bigger problem for my apple trees. Apple blooms are good to 28-29F. The apple trees are so big now, they can't be protected.

My pineapples are growing well I think in response to having the lights on every night.

It is still cool to cold here.

Hey Millet do you see it worth the money on buying the ga3?
Do you also have a supplier i would be able to order from?

David, I purchased a large bottle of GA3 perhaps 3-5 years ago, which will probably be a life time supply. It is a 40 percent concentrate. Using this strength, the spray rate for citrus is 1 gram of GA3 per gallon of water. Therefore, It will probably out last me. If they grow grapes in your area, you should be able to purchase from their suppliers. If you cannot locate any I would be happy to give you 5-grams which should last you a good while (will make 5 gallons of spray). Spray at full bloom. - Millet (727-)

Lol my great grand dad always tells me that when I give him any plant.
And no dice on grape growers here locally.

Roottone is a powder base GA3. Is it possible to mix that with water and achieve what is needed?

I don't know where they get it but Camellia growers will disbud all but one bud and put a drop of GA3 in the bud socket of the removed bud. It is supposed to make a larger bloom.

Roottone is a good product, but unfortunately it does not container Gibberellic acid (GA3). It is a rooting hormone. Roottone's ingredients are shown below.

Component Percentage ACGIH Exposure Limit OSHA Exposure Limit
1- Naphthaleneacetamide.......... 0.067%
2-methyl-1-naphthaleneacetic acid.......... 0.033%
2-methyl-1-naphthaleneacetamide.......... 0.013%
Indole-3-butyric acid.......... 0.057%
Thiram.......... 4.0000%
Talc 95.830%

Are there any rooting hormones that do. I was told that it had it in it but I was wrong.

Is GA3 regulated?

I guess not.

Seems like the miracle drug. LOL About the only thing it didn't say it would do is help me lose weight!

Umm... maybe I'm remembering this wrong, but I seem to recall that solutions of GA have a fairly limited life span.

Edit: Ok, apparently that's only if exposed to light.... never mind
