Creating a Low-Maintenance Flower Bed: Weed Barrier Method with Black Plastic

For a 10×50 ft bed on existing grass, this method minimizes future weeding.

Step-by-Step

1. Spray entire area (including future edging) with a season-long grass/weed killer.
2. Cover with black plastic (heavy-duty, like paint drop cloths), not clear. Secure with metal garden staples.
3. Wait several days for weeds to die.
4. Remove plastic, add thick layer of topsoil and peat moss, slope slightly for drainage.
5. Replace plastic, secure again.
6. Cut planting holes (5 inches wider than plant) in plastic.
7. Plant tall in center, short at edges. Choose sun/shade appropriate plants.
8. Water deeply, mulch heavily over plastic to hold it down.
9. Water regularly for first few weeks.

Bonus

Add spring-blooming bulbs now for early color. Mix in dwarf evergreens for winter interest.

This system creates a virtually weed-free bed for years.
