| ok, I'm a bonsai newbie you could say. I got my first tree from a nursery about a month and a half ago, and it looked really vibrant with new growth and everything. I am at college and I went home this past weekend with my tree (I call it "grasshopper") and put it outside on my deck. I sat out for a while admiring the growth and just looking at it. It looked great.
Today I looked at grasshopper again and suddenly some of the leaves are yellowish. Imagine if you have a green shirt and spill some bleach on it.. that's how some of them look. I moved the branches around a little bit and saw that some of the discolored leaves were perfectly green where other leaves covered them. Any idea what this could be? I'm really worried about my tree, it's been completely healthy and vibrant looking since I got it. Did I overwater yesterday? (once until drips came from the bottom) |

| Hmmm - sunburn. I bet you had the plant indoors too? Chlorophyll is natures sunblock for plants, but it is contained in leaves in direct proportion to the amount of sun they receive. Chlorophyll production also substantially lags sun exposure, so when you suddenly expose previously shaded foliage to bright, direct sun, it burns just like your skin would under similar circumstances. (Witness the leaves that were shaded & are still viable.) If you haven't already figured out where I'm heading: You should gradually acclimatize your plant(s) to direct sun by giving them a few days in bright shade & then some early & late day exposure for a few days before placing them in full sun. Moving them to a full sun location on a cloudy day is also marginally helpful. Al |
