## Overview

Bonide Captain Jack's Lawnweed Brew is a 16 oz concentrate designed to effectively control a wide range of weeds, moss, algae, and diseases in your lawn.

Its easy spray application makes it a convenient choice for maintaining a pristine lawn.

## Description

Derived from Iron, Captain Jack's Lawnweed Brew offers selective control of weeds, disease, moss, algae, and lichens in lawns. The active ingredient is derived from iron, which occurs in nature. Kills many common weeds like dandelion, clover, moss, narrow-leaved plantain, chickweed, and thistle. Works quickly, as dying weeds will be seen within hours of application.

Review: Seemed to work - This was purchased for a peach tree that was getting rot on the peaches as they grew. A company wanted several hundred dollars to spray the tree. Decided to give this a try. It controlled the bugs and minimal rot. We were able to harvest and eat the peaches this year and we couldn’t last year!
Review: Better value than Sunday lawn care dandelion doom - Worked over night! I was worried it ended up raining the night after I applied but I woke up to some very brown weeds in the yard. I’m a Sunday lawn customer and this $5 per gallon vs $22 per gallon with Sunday. I’ll definitely be purchasing this product to take care of weeds and keep our pets and kids safe while playing in the yard! Need to check out more safe yard products from this company!

Didn’t work - mixed at highest rate and didn’t seem to kill the weeds. Maybe set them back but no all kill
