Callus on an Air layer (good/bad?)

Post  Jake16 on Sun Jul 01, 2012 5:19 pm

I have an air layer on an elm and when I looked at it today It has this "callus" around the top part of the cut. I cant remember if I read that this is good or not. Also I didnt have any sphagnum moss so I just put a mixture of potting soil and sand in the tin foil. Help please. Smile

Callus tissue forms first, roots then come from the callus. Just have to make sure the callus doesn't completely over-grow the gap you cut (it sometimes does, especially if you didn't cut a wide enough gap).

Much information available on the internet: google air layer callus

Thanks again,

I saw that in one place but I just wanted to make sure. Thats the only one of my air layers that looks like its doing any thing.

Just be patient. All good things need time. This also goes for air-layers. Any rooting under 6 weeks is very quick. Some junipers you may need over a year before rooting becomes evident. The best thing is to not look at the stem. Just leave it there. If you place a plastic bag around the soil, and then a cover of something that stops the light such as tin foil, you can see the roots growig agains the plastic, and you do not need to distub the soil

Based upon experienced advise I believe its necessary to open the layer up about a month after first setting it to check that all is well. I opened both my layers today and both needed something done, one needed the xylem re-scraped, the other needed the callus re-wounded. Both got new orchid moss. You can't quite set it and forget it.

There are pros and cons to looking and/or not looking. If the roots seem to be growing slowly, and one looks by removing the rooting medium "around", you can break fine roots which are forming and set the process back. If you can see roots through the plastic then you don't need to look any further and not risk breaking the new roots. At least this has been my experience. I have tried "re-scraping" and applying new hormone and moss, etc, when no roots were present, and the results were poor. I think this is because the time to create new airlayers has passed. It is essentially creating a new airlayer at the wrong time of the year.
Best,
Todd

Ok so I just had to fix my oak air layer because ants kept moving the soil away from the cut. I saw these white "bulges" coming from the cut. Is this the beginning of a callus or roots?
