Herbee's Tip

Herbee Greenthumb

Herbee here. Make sure when you read about a poisonous plant, you keep the plant isolated from the environment, such as birds. Never have poisonous plants around children or pets. Take the responsibility for the safety of your family and pets, as well as nature, especially my family, bees! Thank You!
