Replanting bamboo?

[steve1]

The reason I suggested using Albizzia leaves as a green mulch is that they are high in nitrogen, organic, and free. Organic nitrogen breaks down by bacterial digestion not by hydrolysis or mechanical weathering so there is less potential for salt buildup which sucks the moisture out of the roots in high concentrations and causes "leaf burn". A thick green mulch layer will also help retain moisture in disturbed soil of new plantings.
