No, I suggest you use less than 45 scoops. Bamboo is not a heavy feeder and does not need much fertilizer. Use a quality potting soil, add a gallon or so of compost and just work one bottle of Osmocote (2 lb or 907 grams)  into the top inch of soil using enough to scatter it thinly on top of the soil surface then scratch it into the top layer of soil. I promise the bamboo will grow fast with just 32 oz  of Osmocote for each huge container. The biggest complaint about bamboo is that it grows too fast so watch out. Keep growing, Marianne Binetti
