How Does Captain Jack's Deadweed Brew Work?

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.

      Great value dress shoes with nice detailing
      Size: 11, Color: Black, Size: 11, Color: Black
      I bought these black dress shoes for an occasional formal wear, and overall I’m quite pleased with them for the price. Fit & Comfort: The size is accurate (true to size for me). They fit well right out of the box with no major break-in period needed. The pointed toe is a bit more tapered/narrow than I usually prefer, but it’s stylish and not uncomfortably tight. The main downside is the thin padding/insoles — they’re a little firm underfoot. However, this is an easy fix; I’ve already swapped them for better aftermarket insoles and the comfort improved significantly. Quality & Appearance: The quality is solid for the money. The faux leather has a nice shine, and the crocodile-embossed pattern on the toe cap and sides looks sharp and premium in person (see my photos). Stitching is clean, the sole has decent tread for a dress shoe, and they feel sturdy. No loose threads or cheap-feeling construction. They’ve held up well so far after several wears. Value: Excellent bang for the buck. They look much more expensive than they cost and are a solid choice if you’re looking for stylish dress shoes without spending a fortune. Would recommend, especially if you plan to add your own insoles. Perfect for office, weddings, or events where you want to look polished.

      Very shiny, very pointy
      Size: 11, Color: Black, Size: 11, Color: Black
      I'm actually glad I oversized these a bit. These are pointed oxfords with an interesting diamond or scale like pattern on them. Not typically my usual style but it is nice to switch it up every now and again. At an 11 they fit, though I am usually a 10.5 and there are rough bits on the inside I'll have to apply moleskine to. Not really bits that are rough for the shoe themselves, just parts where they don't fit my particular feet right. Other than those bits they were okay as far as comfortability. I wouldn't go walking super far in them or anything, but for a day at the office or for a restaurant or something like that they are perfectly serviceable. I don't think they will hold up in the long term as I do see areas where the construction is a bit lacking. The padding in particular needs some work. I imagine I will be able to keep them around a bit longer with some glue re-application (this is easy to do, and generally if you are anything like me the sole tends to separate on shoes first). Overall I think they are an okay value here. They aren't really comfortable enough for me to be a daily driver kind of shoe, but for a special occasion and to fit a particular outfit they are nice to have in rotation.

      Stylish & Comfortable
      Size: 10, Color: Black
      These men’s dress shoes offer a sleek and modern look. I used them for formal wear, and they complemented the outfit nicely. The design is polished and professional. They stand out. The fit is comfortable for extended wear. The materials feel durable and supportive. The sole provides good traction. That’s important. They are versatile for both business and formal events. The finish holds up well over time. They maintain their appearance. Very reliable. Overall, these are stylish and practical shoes. They combine comfort with design. I would recommend them. Great value.
