The growth of Pennington Smart Seed Pro Tall Fescue and Kentucky Bluegrass around walnut hickory and black walnut trees would not be an issue and the seed should grow just fine as long as it has enough sun and water. All grass seeds are going to need at least minimum sunlight thresholds met in order to survive, even dense shade seeds. If the trees get enough sunlight or a few hours of sunlight, there should be no issue with this grass seed growing.
