Hummingbird Feeder Recipe?
Hummingbirds will reject beet sugar over cane sugar. That is only the first negative. They live on sugar water for energy to eat bugs. Vinegar is acid and pickling uses vinegar. I thought you were joking. Dont feed them acid.
What Is This Plant? (Yucca?)
Definitely not cannabis. It does resemble some sort of dracaena.
