OCCULTATION, also known as tarping, is a great way to create a weed-free garden without any effort. Join us to see how we’ll use the tarp as a placeholder on …


  1. A black tarp with heat more than a clear tarp, So what is the soil temperature under the tarp? Have you ever tested the temperature? Does it get too hot that it will kill the beneficial fungi and bacteria in the soil?

  2. Tilling is killing micro organisms and will cause soil to get hard like concrete over time also why flooding is becoming so common. Commercial / industrial farming – kill the soil and buy more petrol products to grow until soil has no life and land has no value. There is a reason no till has become so popular!

  3. I used that roll plastic that is made for hydroponics….white on one side and black ontehother….tilled, stretched it over, then cut triangular holes to plant in. It worked out great, the white reflected sun up into the plants, ground stayed moist, and weeding was changed from all day to 20 minutes….next Spring though I will lay soaker lines underneath.

  4. Good video. You actually can kill any kind of plant, like wild black berries etc. but doing one modification to your approach.
    You leave the cover for 2-4 weeks (usually 2 weeks w/o light kills all plants), then you remove the cover for 2 weeks. Doing so plants that store their energy in their roots start using all their power to regrow, and right then you place the plastic again.
    Just covered, some plants can survive several weeks, waiting for the light. but if they then start and get covered again, it knocks them out.
    did that to an area of about 180 square feet covered with black berries up to 4 feet high. Knocked them down with a strimmer, 2 weeks of no light, 2 weeks of light, then when I saw green leaves again no light and so on for 3 times. Never again there were blackberries.

  5. The plastic sheet works well. I have found that using an old carpet is also effective. One advantage is that rainwater can penetrate and the carpet can be left permanently, as it degrades with time, mostly depending on the material construction.
    The best crop of Melons and Squashes I ever obtained using this technique. I just laid the Carpet on a Hay pasture in the Fall, and in the Spring, cut holes on 4 ft. centers and planted without removing the carpet. It also has the advantage of keeping the Squash from ground contact, thus preventing infection by soil organisms. Used carpets can be obtained for free from flooring companies.

  6. In FL we're told to use clear tarps, but I can't find any clear UV stabilized plastic. Even though it lets light through, it gets so hot it kills weed seeds instead of just choking them out from light.

  7. question… will blue tarps work as well as black ones? I realize the blue ones wouldn't absorb as much heat from the sun, but they're still opaque and hopefully would occultate like black tarps?

  8. I compost rotted and scraps of veggies etc. Can i spread this under the tarp with cow manure after the tarp has been on for about two or three weeks. Then till and put tarp back on? I live in 9b zone..thanks for your reply.
