    Best time to air layer azalea?

    My friend has a cool looking azalea (not sure what variety) that his parents want to propagate. They've tried taking cuttings but they have failed to take root. I live in zone 8b.

    So I finally brought myself to purchase a bougainvillea this summer with plans on propagating some cuttings for bonsai training.

    Humidity Tray "grid" - there's got to be a better way

    For ease of watering (and upping the local humidity) I'd like to put some of my tropicals on humidity trays. I am not a fan of the tray+gravel+pot method, even though the gravel does look pretty. I'd prefer a nice, sciencey looking grid, like these Humidi-Grow trays that Bonsai Boy has. The...

    Quince, when can I air layer

    I have a very large, old quince bush (about 8 ft high and 8 ft in diameter) at the border of my yard. It is a multistem (literally hundreds), very thorny and produces red flowers in very early spring but rarely yellow, tennis ball sized, fruit. I do not know the species. I would like to know...

    Kishu Air Layer

    Here's another shohin seminar acquisition - a long lanky Kishu. I'm partial to the small tree I think I see in the lowest branch, so I'm layering off the top . . . . . . could be vaguely tree-ish up here too. Two layers at once really: Ugly, but hopefully effective:
