If you wrap the sphagnum with something like saran wrap and tie it, how do you keep that area from cooking in the sun (will trap heat) and how do you water it if the sphagnum gets dry without having to untie it every time?
you put aluminium foil over the plastic wrap to reflect the sun. Its my understanding that it doesn't need to be watered.
I leave mine open on the top. It allows heat to escape and oxygen in. Wrapping with foil will help, the heat is not entirely bad. It will incourage root growth when temps are cooler.
Thanks, LJ, for the foil idea...I've been wanting to try AL with some old garden roses and a pear tree that was planted eons ago, and never needs any spraying and produces a bumper crop. I suppose air-layering would work for an old-fashioned fruit tree?? Just wondering.
I leave an opening at the top and bottom of the wrapping for watering. It is probably best to do these in cooler weather and expect to keep them on for afew months.
I would imagine that watering could be done with a kitchen syringe, the kind that's used for injecting meats with wet seasonings and whatnot, it has a few lateral holes in the needle in addition to the one at the tip. Seems perfect to me, I for one intend to try it.
water or not to water an air layer bundle? If I keep the plant watered is it necessary to re-moisten an air layer moss bundle?
Yes the moss wrapping must be kept moist. Roots will not grow into dry moss. Al
If the package is all sealed up in plastic and foil, will the moss dry out? The water has nowhere to go. I'm just worried about the area becoming too wet if you water it.
just from my experience: i air-layered a shrub rose twice. i followed the instructions i found on the internet-put moistened moss around prepared area, wrap in plastic, seal ends (not too tight) and cover with foil. let it be and found roots in about a month. i noticed moss was still moistened, so, not something i had to worry about.
