Can pre-emergent cause delayed greenup
I applied a pre-emergent in February on my zoysia lawn hoping to prevent chickweed and other early spring weeds from germinating.
This is the first time I've tried a pre-emergent and I'm now left to wonder if this application has caused my zoysia to be extremely slow to greenup this year.
Usually by this date my zoysia is all green and this year it's way behind schedule. The attached photo represents a roughly 5,000 sq.ft. area.
