The safe area used (for a long time now) for the plant testing was standing on a small island in a massive marsh. The island was so small that I could stand on one of its ends and see the other—at least if I chose the narrowest place. I couldn't see the edges of the surrounding water the same way.
This made it perfect for testing various plants, since even if they got out of hand, they wouldn't spread farther than the island. And to guard the place from roaming insects and amphibious beasts, bees built a floating fortress here.
It was standing on a human-made boat, and a garrison of Warrior Bees was constantly scanning the surrounding waters for signs of predators.
Currently, there were a few other plants grown on the other half of the island; the other half was given to five usnea trees.
