Rooting Hormones - need recommendations

jcesarelli

I would like recommendations on rooting hormones, the only one that I am familiar with is Rootone and I would like to know if anyone has had experience and/or recommendations of others that might be better?

Thanks,

Joseph

Are they not all the same?
I get whatever is on sale at the time.
They all seem to work.

They aren't the same, there are different strengths. You may want to search "rooting hormones" and read the threads that show up.

I was dipping my little cuttings in hormone powder, but since it didn't seem to stick, I dipped them in water first and then powder. Which gave them too much powder and killed them all.

(Okay, so it ISN'T like dipping a chicken in flour before frying it!)

Different strengths work for different species, too. So aside from the powder/liquid sort of decision, there is a strength issue. And some have fungicides and some don't.

Thanks Joanie, and thanks for the suggestions.

I believe its Dirr's Manual of Woody Plant Propagation or something like that, that gives exact percentages of different chemicals that yield the best chance at rooting.

Are you trying to sever the tap root on newly germinated seedlings?

I have found that the gel one are highly price compare to the powdered one. I had better result with gel one, never killed a tree for having too much, like I do with powder. Other advantage of Gel or liquid, is uniform application compare to powder. Liquid as another advantage, you can dip it, and let it sit a few minutes to make sure, the liquid fully infiltrate the stem. If you leav it dip long, you should use a milder solution.

On young seedling, if you go with powder, make sure you dont put too much. I would suggest a milder IBA (the active ingrdient)

To give you a short summary :

0.1% IBA is normally for softwood. Flowers, Geraniums etc....
0.4% IBA is Semi-Hardwood... Easy rooting tree
0.8% IBA for Hardwood tree and conifer

For a seedling , I would suggest something in the range of 0.4% since 0.8% will be to strong, and you hare not doing a cutting of wood but rather weak flesh.

The highest I have seen is 1.6% IBA, and rumors says that you can have some 2.0% IBA but never seen it it. The higher rated ones, are only available in liquid and in bulk quantities.

Patrick
