Title: Air Layer Question
Post by: sherwob on January 30, 2013, 04:33 AM
I have been eyeing a great branch on a cork-oak in my yard for some time.  I just stripped off the bark and started an air layer project yesterday.  My question is about the branches above the air layer.  There is about 8 feet of dividing branching up-stream.  Should I thin it back significantly (closer to the size I will want) or is this the energy that is needed to pull back to the new developing roots?  see pix.  Note, the branch has a 4" diameter at the air layer site.   Brad

Leave the foliage for now. You are correct that that will grow the roots.

Hi there.... Paul may be correct, but I feel that if you have 8 feet of branch after the airlayer that maybe a bit too much.
I would think you would want to reduce this to a more manageable length, perhaps 3 to 4 feet.... especially if there are enough branches within the first 3 to 4 feet. You want to balance the need to develop roots in the new area with the need for the growth to survive.

I would like to hear others oppions.

I'd leave all growth untouched.  When it comes time to sever, I'd chop the top back, then sever (in that order so you don't disturb the new roots).

bwaynef's done this before!!

Good advice, bwaynef!

The xylem (wood) that feeds the whole works is left intact, Jay. The photosynthates and auxin produced by the foliage are transported basipedally in the phloem.

Here are some new air layers I did today. The first is a Japanese Maple and will have three trunks. the second is a Crab Apple. I am trying this coke bottle method using only the spout end and cutting the thread area off. I split the side and made  some holes with a hot nail to sew the side closed.  I also am still using the strips of paper towel with rooting hormones applied to it.

 One of the reasons I am trying this method is because I can see if the moss is still  wet and I can see if and when there are any  roots developing. Wondering if I should wrap it with something to keep it from heating up to much? It will be shaded when the leaves come out. You could also use the green 7up bottles.
