I posted a couple of messages that involved defoliation : it can be accidental (hot wether, lack of watering) or intentional (for bonsai growers and for various reasons). For instance, this Acer palmatum 'Orange Dream' had leaf spots. At the same time, the leaves were bigger than I wanted, a second flush means smaller leaves. But basically, I was looking for a way to make it healthier : Cheering ourselves up with Maples Pictures I took this evening. I could (should) have removed buds starting from the same point, but I was not sure of how the weather would allow. Still a bonsaï in the making, not a bonsaï. Already too long an intro, so I won't develop. The second picture (top of the "canopy) was taken after it was moved in the shade. The colours are pretty true to the actual ones. And I keep on feeding leaf-cutter bees, but as long as they don't strip it off totally, I turn a blind eye on the little beasts... ^_^ There's also the 'Jerre Schwartz', accidental defoliation => slip-potting, without watering too much : ER : slip-potting It should work. Intentional defoliation for "aesthetic" purpose (Bonsai stuff) . Seedling from unknown parentage, with long internodes. Defoliating it allows pruning (hoping shorter internodes) and smaller leaves : May 2019 : June 6th. I had "slip-potted" it a couple of weeks before in a plastic tray (TV dinner) : 12th July 2020.
