Buying Guide
What should you consider when picking a weed and feed fertiliser? Start with lawn size, weed spectrum, and preferred application method.
- Lawn size and coverage: Choose a product that matches your square footage or offers scalable coverage for larger yards.
- Weed targets: If you have dandelions and clover, pick formulations explicitly listing those weeds. For crabgrass, select formulas with crabgrass prevention or certain 5-in-1 options.
- Grasses and exclusions: Some products list grasses they should not be used on. Verify your lawn type (St. Augustine, centipede, bermudagrass, etc.).
- Application method: Granules vs. liquid hose-end sprayers differ in ease, speed, and uniformity of coverage. Hose-end options work well for small-to-medium lawns; granules are typically better for larger areas.
- Timing and season: Apply during active weed growth in mild to warm temperatures. Avoid extreme heat or drought, and follow label directions on daily and seasonal limits.
Frequently Asked Questions
- What is the best weed and feed for a small lawn? Answer: Products like Scotts Turf Builder Weed and Feed5 (4,000 sq ft) are convenient for small to mid-size lawns due to combined weed control and feeding in a single bag.
- Can I use weed and feed on St. Augustinegrass? Answer: Some formulas explicitly avoid St. Augustinegrass varieties; check the label before application.
- How often should I apply weed and feed? Answer: Many products advise no more than two applications per year unless labeled otherwise.
- Is liquid weed and feed faster acting than granules? Answer: Liquid formulations often show quicker visible results because they are absorbed through the leaf surface after spraying.
- Will these products prevent weeds all season? Answer: Several products include a barrier or long-term preventions (up to 6 months) when used as directed, but ongoing lawn care can help maintain weed resistance.
