I put the air-layered Santa Rosa plum in the ground this evening. I pulled the big forsythia out this morning with a lot of rope and a big come-a-long, cut the root ball off with the chain saw, dragged off the brush, washed the dirt out the root ball and dragged it off, chopped out some more roots, hoed it up, raked it out, planted the plum.

It had lots of new roots filling up the pot and has been growing fast.

@firephoto Ait layering was that technique, when you leave the "cutting" on the branche and bring a pot of dirt there for the future cutting to grow roots in the middle of the branch, correct? How do you keep it moist? I tried this once and the soil dried out and didn't grow anything.

@levampyre Yes, I peeled the bark in a section, covered with moss, dirt, ash, and wet that. Wrapped it with plastic and used rubber splicing tape on each end to seal it good. I used a syringe to inject water into it every couple of weeks or more when it was hot. Maybe 20cc each time.

Here's the post when I cut it off, shows how it was wrapped up. There's many layers of plastic because I had a narrow roll of the stuff I used.

@firephoto So would you say, it's worth the effort? Do your air layered cuttings have higher survival rates?

I've found that I find it quite complicated to keep the air layered bits moist for long enough to develop roots, esp. in the dry summer heat. It was way less effort to just take a larger number of small cuttings, stick them in a barrel full of soil in the shade and water them all together once a week. Or to grow them from seed in situ, which has the highest survival rate in my location.

@levampyre This has been the only serious air layering I've done. I've staked things into the dirt before to get roots but never a tree. This was the only option with the plum besides grafting and I haven't had any luck getting a graft to take from this tree.
@firephoto Ah, true. I'm sure it's not as easy trying to multiply trees with the usual stick in the ground method. I usually do shrubs like berries. And they take very well. But actual trees I've only grown from seed so far. Hoping to be able to later graft special varieties onto them.
