Plastic is only good for strangling Ex's & Plant life. It can't breath enough, causing stragulation & bad fungi's. The Burlap is wonderful. Not digging raises your plants higher (1 to 2 ft. min), causing easier detection. But camo works, dead limbs close by, to break up a pattern. That's key, to break the patern. Spray liq. seaweed on burlap. it's a natural root stimulator. Never walk directly to the site, stop downwind away & out of site. Sit, relax & listen. If you hear a cough, other body fuctions, radio static, movement, go home. I love planting non-colorful vines close by, you can train them to (almost) cover your plant(s).
If you poured liq. seaweed, molasses, & Thrive at the sites now, the soil will be a Whole lot softer by planting time.
