A weed barrier is often a fabric landscaping material that helps prevent weeds from growing in your garden or around the edging on your lawn. Weed barriers work by blocking the sunlight from reaching the soil, which inhibits weed cultivation. Air and water can still get through the weed barrier so your plants and flowers can thrive. You can add plants and bulbs to a garden with a weed barrier at any time. The landscaping fabric cuts easily with household shears or a knife.
Slice an X in the weed barrier material with a sharp knife directly over where you plan to plant the bulb. Spread the material apart and brace it out of your way with weighted objects. A pail or another garden tool will work.
Align the bulb planting tool over the bare soil between the open X mark. Insert it straight down into the soil. Pull the tool straight back up and squeeze the handle to release the soil plug.
Sprinkle a small amount of bone meal or bulb booster into the hole.
Place the bulb into the hole in the correct planting position. Follow the planting directions on the bulb packet regarding the bulb placement. Teardrop bulbs, such as tulips and daffodils, are planted with their tips facing up. Plant flat bulbs with the flat side up and the roots facing down.
Replace the soil over the bulb and allow the weed barrier to fold back flat. Water the area well after you plant your bulbs.
Add a 3-inch layer of organic mulch on top of the weed barrier for moisture retention and to protect your bulbs.
