Iron-Powered Liquid Post-Emergent Weed Killer
Weed Wizard is a selective, broadleaf herbicide that kills weeds on the spot without harming your turf or ecosystem. Weed Wizard uses one active ingredient--iron--so it's safe to use on your lawn. Spray away dozens of different broadleaf weeds harness the power of chelated iron and weed control wizardry with Gnome's water-saving wand sprayer.
Benefits:
- Kills weeds down to the root without damaging turf
- Highly effective on dozens of weed species (e.g., dandelion, chickweed, clover)
- Saves water and time with easy, hose-free application
- Feeds soil system rich iron, an essential micronutrient for lawns
- No glyphosates or carcinogens, found in traditional weed killers
- Safe to apply 24 hours before (or after) fertilization
Active Ingredients: Chelated Iron
Directions for Use:
- Shake concentrate bottle well before use.
- Mix 5-ounce concentrate and 1 gallon of water in reusable bag (or 1 part Weed Wizard for every 24 parts water).
- Activate sprayer by pulling tab (new batteries included) and screw on to gallon bag.
- Apply directly to weeds until wet from leaf-to-root. Aim to only spray weeds. Too much iron won't kill your grass but can create temporary brown spots.
- Do not apply this product to newly seeded areas or within 2 weeks of planting seeds or transplanting.
For best results, apply Weed Wizard before you fertilize to kill off weeds and grow back any patches left behind. Re-apply in 3-4 weeks if necessary.
Highly effective weed killer from iron
Unlike traditional herbicides that rely on carcinogenic biocides to control weeds, Weed Wizard is an iron-based alternative that you can spray yourself, without a head-to-toe hazmat suit.
Weed Wizard works like magic thanks to one beautifully simple law of nature: lawns have a much higher iron tolerance than broadleaf weeds, so your lawn continues to flourish while the weeds die out on the spot.
To be sure you and your family are safe, we always recommend wearing gloves, glasses and clothing while handling concentrates and safely disposing of your bottles.

Ahem, we hope you enjoyed that.
First off, please do not drink the fertilizer. Any fertilizer can be dangerous if a human being or a pet consumes it (fun fact: we gnomes are uniquely evolved to digest fertilizer).
But the real concern is whether the fertilizer makes your lawn less safe for play. Traditional, dry, pellet-based fertilizer will remain on your lawn for up to 72 hours, posing a risk to pets and children. With Gnome, you can get back to playing in the grass 4-24 hours after applying the fertilizer (as soon as your lawn dries). Lawns drink, they don’t eat. Liquid fertilizer is just better.
