What amount of weed/couch / moss competition should I worry about when reseeding?
- 
Before sowing, remove or suppress weeds, moss, and unwanted plants, as they compete for light, water, and nutrients.
 - 
In some cases, light use of a selective herbicide or moss killer (applied before sowing) may be justified, following instructions carefully.
 - 
After sowing, keep mowing and maintenance practices strict to favour the new seed over opportunist species.
