Whether Bio Advanced 12 Month Tree and Shrub Protect and Feed II Concentrate is the only product that you need is really going to depend on what nutrients are needed and if issues arise with your specific trees. You may try contacting a local master gardener or arborist at a local nursery or cooperative extension office for the best advice on what oaks in your area need.
