2. If the soil is heavy clay, break up the bottom and sides of the hole with a pick or similar tool.
Mix Azomite/Rock Dust, Rock Phosphate, Greensand, Bonemeal, and Lime at a ratio of 3:3:2:1:1
Sprinkle the number of heaping handfuls listed below at the bottom and sides of the digging hole for the appropriate size plant
3 gallon pot: 1 handful
5 gallon: 1.5 handfuls
7 gallon: 2 handfuls
10 gallon: 3 handfuls
15 gallon: 3 handfuls
25 gallon: 4 handfuls
4. Take the bamboo out of the pot (or cut the pot off). If it looks root-bound you'll want to gently coax the rhizomes out of their tight circling. It helps to cut some of the feeder roots in order to free up the rhizomes.
5. Apply mycorrhizal fungi to the exposed roots.
6. Place the plant in the bottom of the hole adjusting the base so it has full contact with the soil (no air gaps), is tilted so the bamboo is as vertical as possible, and the top of the rootball is level with the soil level. If the area is prone to be wet, plant a little high, 1"-3" above soil level.
7. Backfill with 50/50 mix of native soil and compost. If the rootball is above ground level, add soil up to the level of the root ball.
8. Compact the backfill moderately with the heal of your foot.
9. Apply fertilizer (organic preferred) and Ironite if necessary.
10. If weeds may be a problem apply around the bamboo a sheet mulch out of newspapers, cardboard, or (preferably) burlap.
11. Mulch liberally in a circle around the bamboo, taking care not to pile the mulch against the base of the culms (in a doughnut shape).
12. Tie and stake tall bamboo if necessary to prevent from blowing over in high winds.
13. Water in well.
2. If heavy clay, break up the sides and bottom with a pick.
3. Put the bamboo in & backfill.
5. Water in well.
