Wow
@purpleinopp yours sure have been busy! Thanks for the update! My scheffs. have been constantly putting out new leaves from March to now. Along the way though I've been periodically spraying with neem oil which may be hindering the rapid growth I've seen in the beginning of the season. Still it's necessary though b/c I believe I may have an unseen nibbler.
I first notice this when the new leaf in the bottom left of the pic started to loose its petals then the growth became stunted all together like it never even budded in the first place. Once I began the neem oil regimen back in May or June all was fine until recently.
Though it continued to grow fuller, toward the middle of July I noticed yellowing of the bottom leaves of both branches. Then the leaf petals would begin to fall. So I'd get rid of them immediately, remove from the other nearby plants, and begin spraying and carefully watching again.
I know the yellowing is sometimes normal and the dropping of leaves too as newer ones form. However what worried me was how where the place the leaf dropped from turned brown as if it was chewed off by something. Today I'm a little less worried as the condition seems to be more under control. But I am now considering (before further loss) the lack of nutrients in the soil or presence of salts or even compacted soil/lack of oxygen.
Here's one of the scheffs. today after the loss of about 3 to 4 leaves on each branch. The last dropping: about 3 1/2 weeks ago. Notice the bottom leaves/new branches (once "chewed off") now forming again after 3months time
Again thanks for your update and interest
@purpleinopp. Stay tuned for the update on my other Schefflera turned bonsai. Perhaps you can help.
