Captain Jack's Deadweed Brew is a non-selective herbicide that uses Caprylic Acid to quickly burndown and control many of the most common herbaceous broadleaf and grassy weeds, algae and moss. This product has been designed to be used anytime of the year (it is effective in temperatures as low as 40°F.), but it works best during warm and dry conditions. Application during cold weather can delay the appearance of plant damage. Captain Jack's Deadweed Brew is extremely versatile; it can be applied virtually anywhere around the home or garden. It can also be used in lawn, gardens, landscaping and other cultivated areas prior to planting grass, flowers and vegetables. As soon as the desirable level of weed control is obtained, the area can be re-planted.
