Lightest

this is the garden roll

For short single-season crops on fine, well-prepared beds. The least material between sun and soil, so beds warm a touch faster, but it tears more easily on rough or windy sites.

The workhorse

The balanced default for most field beds through a full growing season. Strength and cost meet in the middle, making it the safe pick when you're not sure which way to lean.

25.4 µm

Toughest

Maximum puncture and wind resistance. Step up to this gauge for long-season or double-cropped beds, windy sites, and cloddy or stony ground.

>720%

Elongation before break

ASTM D882, transverse direction. The film stretches with the bed instead of tearing (machine direction: >280%).

4-12 mo

Adjustable soil life

Order the breakdown window with the roll: rated to hold in the bed for 4, 8, or 12 months, then let go.

90%

Soil decomposition within a year

In soil at 20-30 °C and 60% humidity, the blend is 90% decomposed within one year of tilling in.

Biodegradable Mulch Film for Garden Beds

Which mulch film thickness is right?būmigro biodegradable mulch film comes in three gauges — 0.5, 0.7, and 1.0 mil — drawn at the same scale. Match the gauge to your season length and how rough the bed is; thicker film resists wind, punctures, and end-of-season tearing.
