Nice brown thumb avatar! Looks like a handmade ceramic brown thumb!
Theres all sorts of thumbs,
Burnt thumb ( too much fertilizer, or sun)
Bone thumb (bone dry, they never water!)
Bleeding thumb ( your lawn service left your trees bleeding sap at base of trunk, hence bleeding thumb)
Emerald ring thumb (all plants turn in to emerald green, or worth more than emerald rings! Hands of an alchemist, turning yellow of death, into vibrant green of life! a rare breed)
sorry for topic derail, but i started the topic! LOL
