Inor - what are you considering planting.
I have a similar situation. I have a field planted in mainly St Augustine that I want to convert to a pasture grass.
St Augustine is similar to Centipede grass. Low and slow growing turf that goes dormant in winter.
I need a year round grass that can take full sun and I don’t believe fescue is it.
I was considering a blend of Bermuda and fescue.
If you’re on to a different grass please share the information
