If used in large amounts, oak sawdust can immobilize soil nitrogen during the decay process, starving plants of important nutrients. It can also blow away easily if dry and may be unattractive in some landscape uses. Sawdust mulch usually needs to be replaced every year or two, making it a high-maintenance choice for landscape planting. On its own, oak sawdust is minimally effective for water conservation.
