I have been curious about bonsai trees for a few years now. I've considered getting on, but I tend to like the look of trees that are better grown outside, so I haven't gotten one yet.
You're really into these! You have a lot, and that's impressive. I'm sorry the birds keep ripping them up for their nests. Would it help if you put a pile of sticks and branches somewhere near the trees as an "offering" to the "demons of the sky?"
Never a better time to start than the present right? I do enjoy bonsai, it's one of the few things that actually help de-stress a person properly. My neighbor previously put out hardwood sticks for them and it - although they are territorial (technically, yeah no, not really) - literally caused them all to come flocking. But then a gain, those were not a 'few' sticks.
