Plastic Bonsai Soil Scoops (Pack of 3) If you want the ultimate flexibility on your potting bench without a heavy price tag, this multi-size plastic bonsai soil scoop set is your answer. Lightweight, durable, and highly practical, these nested scoops give you the exact right tool for every tree in your collection. Just like their high-end metal cousins, these feature a steep, tubular slope that acts as a funnel, directing gritty akadama or pumice exactly where you want it. Use the large scoop to quickly fill the base of your training pots, and switch to the smallest one for precise top-dressing around delicate moss.
