Here is my problem. I have a new Fukien Tea Bonsai and I am going this coming June on a 11 day vacation. I have no one available to care for it. How do I water it while I am away? I don't want to over water it and flood the house and kill the beautiful tree. Please provide info and any links to devices. proven methods would be fantastic. thanks.
There are watering systems, but I cannot help you with this, I have no experience with it.
Having bonsai is like having a pet animal. You need to make arrangements for when you are not there. You cannot leave your trees unattended.
If you cannot take care for them, or if you cannot find someone to take care for them while you are away, don't take them.
