Fiesta® Selective Weed Killer and Captain Jack's Lawnweed Brew® (formerly Bonide Weed Beater® Fe)* in retail sizes, are selective, broadleaf weed killers that kill only the weeds and not the desired turf.  Using a specially formulated iron solution, Fiesta and Captain Jack's Lawnweed Brew are game changers in the organic lawn care industry, the first effective weed killers that do not contain toxic synthetic compounds.  The choice of professional applicators, these iron-based weed killers leave lawns healthy and weed-free!

Fiesta and Captain Jack's Lawnweed Brew work quickly, delivering visible same-day results, even in cool weather. With a unique ground breaking iron-based formulation, Fiesta and Captain Jack's Lawnweed Brew are highly effective and have no unpleasant odor. Pets and people can re-enter the treated area as soon as the spray is dry, the minimal period allowed by the EPA. Suitable for broadcast application (entire lawn) or spot treatment, Fiesta and Captain Jack's Lawnweed Brew help your lawn look its best without toxic, environmentally-harsh synthetic chemicals. The top choice of professionals, we are now excited to offer Fiesta in smaller, more home friendly sizes under the Captain Jack's Lawnweed Brew label!  Now you can treat your own lawn with professional-grade results!

    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.

    Credit Card and PayPal Claims Filed First or Review Extortion:
    At GrowItNaturally.com, 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 and 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 our hands are tied and this will very much slow down the resolution process.  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 initial contact to us. This then becomes a legal issue and may be referred to our legal counsel.  We also have every right to forward the threatening e-mail to the proper review agencies and state or federal authorities.
