Q.zoysia grass planted in fall
Planted Geo zoysia first of October. When can I use weed control? Spray or granular? Can I put down pre-emergent for crabgrass? Sod is still dormant to this point.
Proper mowing, irrigation and fertilizing will reduce weed problems.
For best results from your new sod and a fertilizer have a soil test performed on your lawn and fertilize accordingly.
