Freshly sown seeds have a surprisingly difficult job. They need moisture, good contact with the soil, and protection from the kind of downpour that can turn a carefully prepared seedbed into a tiny muddy landslide. A loose piece of burlap can help with all three, making it a useful trick when the weather, soil, or local birds seem determined to make seed-starting harder than it needs to be.
The important word here is “loose.” Burlap should not become a heavy blanket smothering the bed, and gardeners should not leave it sitting there indefinitely. Used correctly, the coarse fabric slows moisture loss, helps keep seeds in place, and can reduce soil disturbance from watering or rain. Used carelessly, it can interfere with emerging seedlings and create a damp little hideout for problems nobody invited to the garden.
