Planting Info

1. Dig a hole 1.5 times as wide as the diameter of the rootball. Depth of the hole should be equal to depth of the rootball.

2. Set plant in the hole so the top of the rootball is even or slightly above ground soil level.

3. Refill around the rootball with a mix of 1/2 existing garden soil and 1/2 Earl May Organic Planting Mix blended with Earl May Structure. Step down on soil to eliminate any large air pockets.

4. Build a soil ring the size of the rootball around the plant, to help hold in water.

5. Add a 1 inch layer of mulch around the plant, keeping mulch away from the trunk.

6. Water slowly with Earl May Plant Start mixture right away. Enjoy watching your new plant grow!
