Keep the clover and alfalfa mowed to a height of about 8-10 inches, keeps it succulant, or when it appears to be going to head/seed/blossom. If it goes to head/seed/blossom then the weeds and grasses that are in it will go to head /seed. Never mow in a drought. Mowing weeds will usually control them but will help thicken grasses. Grasses are the worse enemy of the forage plants, they'll always over take it!.
Taste the product before limeing or fertilizing and check the sweetness. If it's bitter then it needs lime. Spray the grasses as they appear after mowing the field. Never spray in a drought situation. After the fall brown out of weeds and grasses you can allow the product to grow, infact we suggest that you hit it with a stimulant to bank for the late fall/winter.
