Cally That's ineresting, I've only air-layered. Scratch bark on underside of branch, squash a good handful of moist compost round it, hold compost in place and stop it drying out with clingfilm wrapped round and round. When roots are visible and reasonably abundant against the clingfilm, cut through the branch and pot up the cutting.
I did it for insurance when we knew we were going to have to move our fig tree which at the time was about 3 ft high and 3ft across.
Figs grow on the new growth at the ends of branches, therefore prune to encourage new branches.
Greenhouses - if you're dismantling one, label every single piece, including the glass, with where it came from. Makes it a lot easier to rebuild.
Water butt - much quicker to take lid off and dip watering can into it, than stand waiting while water trickles from the tap. If you're using 12 cans of water inside the greenhouse, this matters!
However, it is giving me time to work on the area where the greenhouse is going. I'm putting raised beds next to it. This gives possibilities! Under bench level where you have a raised bed close isn't going to get much light, so could be used for storage. In which case, would putting the raised bed up against the greenhouse offer useful winter insulation? I've always liked those Victorian greenhouse built 3ft underground, with a flight of steps down to the door.
