Sunfall on Main is committed to selling only plants that are chemical free. Most commercial greenhouses use neonicotinoids (neonics) to keep insect populations down. They treat the soil and the plants take up this chemical systemically. Neonics have been shown to have a detrimental effect on bee populations. Staying away from chemicals and having healthy soil and good garden practices will give you the best plant results. Thank-you for considering the bees environment and ours!
