How to Apply Liquid Weed & Feed Fertilizer
- 1). Choose a weed and feed with lots of nitrogen but make sure it is mixed with phosphorus and potassium. Pure nitrogen will burn and kill your lawn; phosphorus and potassium dilute the nitrogen while adding their own nutrients to the mix.
- 2). Mix your weed and feed with water. Pure weed and feed will burn your lawn. Mix 1 quart of weed and feed to every 5 gallons of water. Stir well and pour into a hose-end garden sprayer.
- 3). Spray the weed and feed evenly over your lawn, moving the garden hose in wide, sweeping motions. Move steadily backwards, going over the same place no more than twice. If you run out of weed and feed, refill the sprayer and continue.
- 4). Apply weed and feed again in mid-June. Most grasses and weeds have a growth spurt in the middle of the summer. The grass will benefit from a boost of vitamins and you will benefit as any remaining weeds absorb more herbicides.
