How Does Captain Jack's Deadweed Brew Work?

Finalsan Organic Non-Selective Weed Kille RoundUp Alternative

Herbicidal soaps work by penetrating the waxy cuticle of plants, causing the plant to dehydrate and die. The active ingredients accumulate in plants and cause intracellular damage, leading to cell death. Activity is non-selective and will kill plants the soap comes into contact with, but will not translocate to underground portions of the plant or harm the bark of mature, woody plants.  Can be safely sprayed around the base of trees, shrubs, hops, grapes without worry.  

Use on weeds within vegetable and flower gardens, landscaped areas, lawns (for spot treatment only), in the vicinity of small fruits and fruit trees, around and on buildings, sidewalks, fences, bark mulch, driveways, patios and gravel.  Use on moss and algae, around and on buildings, roofs, decks, sidewalks, fences, bark mulch, driveways, patios and gravel. Finalsan can even be used in cool weather. Areas can be planted five days after treatment.

Captain Jack's Deadweed brew reduces tree toxicity risks and leaves no harmful residue in the soil. It won’t stain bricks, concrete or asphalt and people and pets can re-enter areas once spray dries.

    Shipping & Return Policy

    We offer a 30 day return policy from the date of shipment 

    At Green Earth Ag & Turf LLC, we pride ourselves in making all attempts to get your order out the same day (if ordered early enough) or within one business day of your order.  We do our best to securely package your order, and you will promptly receive an e-mail with tracking information when your order is packed for shipment.  We ship many orders every day, and the carriers usually don't notify us of delays or damage, so we ask that you track your packages and promptly let us know if there is a delay.  We will do our best to solve the problem, but many times may require the receiver to work directly with UPS or The US Postal Service.  Once the carriers (UPS or the USPS) pick up the package, we have no control over delays or transit time.  Transit times are no longer guaranteed by UPS or USPS, even though it may display such times.  We cannot refund money for or speed up deliveries not delivered in the time listed by the carriers.  We are not responsible for orders that are delivered by the carrier and lost or stolen.  For products damaged by the Post Office or UPS, it is required that the original box, label and product be saved.  Pictures must be taken of the damage or we will not guarantee a rebate or replacement if the damage occurs in transit.

    Free Shipping Policy:
    For items with free shipping, we have the right to choose the carrier, either the US Postal Service or UPS.  Please e-mail us if you require a PO Box only or other shipping requirements.  If one carrier is required and it is not the most cost-effective means, we reserve the right to charge additional shipping fees.  

    Return Policy:
    Please email us at prior to making any returns so we know how to credit and return product payments.  We inspect all returns prior to making any refunds; refunds are only made after product is returned in good condition.  Products may not be returned if the seal has been broken.  Shipping charges are not refundable. All returns must be in new, unused, and mint condition.  Product must be returned to us prepaid in the original manufacturer’s packaging.  Green Earth Ag & Turf LLC is not responsible for any shipping damage in transit or packaging failures, leaks etc.  The buyer is responsible for any return shipment costs, including products that shipped to buyer with "free shipping".

    Please make sure that your return is packaged securely and shipped via UPS, FedEx, or the USPS and note the tracking number.  All packages should be insured in case of breakage or loss.  Green Earth Ag & Turf LLC is not responsible for returned items damaged or lost in transit.

    If you order an item and then decide you do not want the item, it is your responsibility to return the purchase to us prepaid. Refusing delivery does not constitute a waiver of your responsibility and the return shipping charges will be deducted from any refund.

    Credit Card and PayPal Claims Filed First or Review Extortion:
    At Green Earth Ag & Turf LLC, we pride ourselves on excellent customer and technical service.  When issues do arise, often due to carriers such as UPS or the Post Office, we respond and work out the problems to the best of our abilities. Our reviews show our extensive service record.  Please contact us via e-mail or telephone first to see if the problem can work out quickly and fully through our extensive troubleshooting experience and highly rated customer service department.

    PayPal and Credit Card Claims Filed Before Contact: If a PayPal or credit card claim is filed before first contacting us directly and attempting to resolve it, we can not help out any further until the claim is fully processed, which can often take weeks or months.  If we are contacted before a claim we can often resolve issues the same day or very quickly.  However, once a claim is filed we must follow the policies and processes of the merchant, and this will very much slow down the resolution process and ultimately your resolution and compensation.  We reserve the right to appeal any unfounded claims, especially those not initially attempted to be resolved with us directly, and it is our policy to do so.  

    Review Threats: Our policy is that we will not respond when review threats are the first contact; such as when a threat of a bad review if a full refund is not sent is the manner in which we are approached. This then becomes a legal issue and may be referred to our legal counsel.  We also reserve the right to forward the threatening e-mail to the proper review agencies and state or federal authorities, and it is our policy to do so.
