marcotting vs rooting question

<< < (5/6) > >>

Mike T:
I have a very high success rate on lychees, rambutan, sapodilla, wax apple, guava, langsat, sour sop, canistel and others. In the last 2 weeks I have put over 200 marcots on my trees and expect most to work well from experience. Pity its hard to post pics these days.
Anyway I see a few red flags in the pics and descriptions. Ideal branch width is 1cm to 3 cm but micromarcots are easy. Ideal ringbark width is 1cm to 2cm not like in the pics below. Paint or brush with rootex or clonex 8g per l concentration. I prefer gel to powder. Have pre prepared ziplock (I use 15 x 9cm mostly) cut on one side then tape over ring back. Tape it up well. Aluminium foil does not change the success rate. Remove in 4 weeks to 6 months with 8 weeks being average. Make sure they are well rooted unlike the plant below in the pic. Trim then pot. EASY. The mix in the bag I use is 50 : vermiculite and coco coir but sphagnum is fine. Below does look too leafy with too many roots and should be settled in a pot until properly rooted.The ties shown are less secure and looser than using electrical tape. The width of bark removed below is way in excess of required. In many cases it works out better than grafting for tree vigour and speed to fruiting.

It was cut early, but you can make it work. I would cut it back to the second pair of leaflets and then trim those so that it only has 4 leaves on the whole tree. Bag it and mist the leaves several times a day (if possible) to prevent desication.

We commercially layer rambutan, for example. We must get 90% or better. Wed never get that with cuttings if any at all.

I say that because of Macadamia. I have air layered lychee on a commercial level. When we tried macadamia on a small scale we got callus formation but no roots until we cut them off and treated them like cuttings. Was it a fluke??? I don't know. Also, Atemoya can be rooted from cuttings according to Australian literature. I have never gotten it to air layer successfully because it has weak wood and the layers have always gotten snapped off by wind. In theory it works, but in practice its not practical. That is why I add the caveat.

Thanks Nate, if it makes any difference I was working with integrifolia. I wonder if tetrafolia and its hybrids are easier to layer. Maybe I should try again.

Finca La Isla:
I think youre getting pretty good advice.  Id probably leave 12-15 leaves on that layer.  Damp and warm.

Thanks, all, for the suggestions.  I have trimmed the leaves back more severely.
