Looking to slice overseed a lawn with known Necrotic Ring Spot issue. Want to introduce more fescues/per rye and improved KBG varieties. Do these choices sound appealing to you? 1) 85% Creeping Red fescue, 15% KBG "Moonshine" mix from Reinders. 2) 33% Creeping Red fescue, 33% Per Rye, 33% KBG "Shamrock" mix from JDL (park and rec mix) I know the critical constraint here is the KBG - I don't want to exacerbate the NRS problem by introducing weak cultivars of KBG. What do you think? If neither of these, ideas??
