Built to remove risk, not create it
The real difference
Most mulch failures don’t come from the material.
They come from how it’s used.
Polyethylene stretches and hides stress — until it fails.
It also fragments into microplastics that remain in the soil.
Compostable mulch behaves differently:
• It does not hide mechanical stress
• It is designed to biodegrade into water, CO₂, and biomass
• It eliminates plastic contamination entirely
This is not a small difference.
It changes how you select, install, and manage mulch film.
▶ Understand the technology behind mulch performance
FilmOrganic materials are independently tested and certified to verify true biological breakdown —
not fragmentation into microplastics.
That certification exists for one reason: to remove doubt when decisions matter in the field.
Since 2014, FilmOrganic mulch has been used across hundreds of farms in North America —
from Alaska to New Jersey, from Hawaii to Washington, and throughout key growing regions like Tennessee.
It is used across a wide range of crops, including melons, strawberries, tomatoes, peppers, eggplant, pumpkins, squash, garlic, and high tunnel production — among many others.
Adoption continues to grow for a simple reason: it works under real field conditions.
Risk & Reliability
Is compostable mulch riskier than polyethylene?
Using the wrong mulch system is risky.
Polyethylene hides installation mistakes by stretching.
Compostable mulch exposes them early.
That is not a weakness — it prevents late-season failure.
When properly matched to the crop and installed correctly,
compostable mulch is as reliable as polyethylene — without leaving microplastics behind.
Why do some growers have bad experiences with compostable mulch?
Most failures blamed on compostable mulch are actually system failures.
Not material failures.
Almost always due to:
• Wrong lifespan selected for the crop cycle
• Incorrect film width relative to bed geometry
• Excessive tension during installation
• Poor soil preparation (stones, clods, sharp edges)
• Treating compostable mulch like polyethylene
Compostable mulch must be selected and installed as a system.
▶ Understand what actually controls mulch durability
Installation follows the same principles as polyethylene —
but requires more attention to setup, as compostable films are thinner and less tolerant to overstretching.
Once properly set, installation becomes consistent and repeatable across the field.
▶ See how to install mulch properly
Does compostable mulch stretch like polyethylene?
No. Compostable mulch does not tolerate overstretching as forgivingly as polyethylene.
Polyethylene can stretch excessively without visible damage —
but that stress often leads to failure later.
Compostable mulch signals stress earlier.
This is a feature, not a weakness.
What causes premature failure in mulch films?
The real causes are:
• Incorrect width → excessive tension
• Bed height not matched to film width
• Installation too fast
• Sharp soil edges or stones
• Film lifespan shorter than crop cycle
• Aged or improperly stored rolls
Thickness cannot compensate for mechanical mismatch.
Cost & Economics
Is compostable mulch more expensive than polyethylene?
Upfront: yes.
Total cost: usually no.
Polyethylene is cheap to buy — expensive to live with.
It hides real costs:
• removal labor
• disposal
• transport to landfill
• equipment time
• residual plastic contamination
Most growers save 2–3 weeks of labor per season.
▶ Understand the real cost of plastic mulch
What costs are eliminated with compostable mulch?
• End-of-season removal labor
• Disposal fees
• Transport to landfill
• Equipment time
• Residual plastic contamination
Compostable mulch shifts cost from cleanup to production.
Why is roll price misleading?
Mulch film is not a product — it is a process cost.
If you only compare roll price, you miss:
• labor
• downtime
• disposal
• long-term soil impact
Who It’s For (and who it’s not)
Who is FilmOrganic designed for?
Professional growers who:
• Plan their crop cycle
• Use proper bed preparation
• Want predictable outcomes
• Value labor efficiency and soil integrity
• Use proper installation equipment (mulch layer)
Who should NOT use compostable mulch?
• Growers unwilling to adjust installation practices
• Operations relying on “one film fits all”
• Situations requiring high-barrier fumigation films (VIF/TIF)
• Operations without proper mulch laying equipment
Why “one standard film” creates problems
Because crops, climates, and soils are not standard.
Using a single film across all applications forces compromise
and increases failure risk.
Planning & Matching the Right Film
How do I calculate linear feet per acre?
Linear footage depends on row spacing (center-to-center).
1 acre = 43,560 sq ft
Linear feet per acre = 43,560 ÷ row spacing
Examples:
• 5.0 ft → 8,712 linear ft
• 5.5 ft → 7,920 linear ft
• 6.0 ft → 7,260 linear ft
• 6.5 ft → 6,702 linear ft
What information is needed to recommend the right film?
• Crop
• Planting and harvest window
• Bed width and height
• Equipment type
• Climate region
• Soil conditions
The more precise the input, the more reliable the recommendation.
Agronomic Mechanics
Why does bed height affect film selection?
Higher beds increase sidewall angle → more tension.
More height = more width required.
How do I determine the correct film width?
Film width must account for:
• Bed top width
• Bed height
• Buried edge (typically ~6 inches per side)
Width =
bed width
(2 × bed height)
anchoring allowance
Mulch film width is a geometric requirement — not a preference.
Example
Bed top width: 26”
Bed height: 5”
Calculation:
26” + (2 × 5”) + 12” anchoring = 48” film
Choosing the correct width is critical to avoid tension, tearing, and premature failure.
Most issues disappear when width is properly selected.
Custom widths are available for specific bed configurations —
it is always better to match the film to the bed rather than forcing a standard size.
Why thickness doesn’t fix a width problem
Thickness adds strength, not flexibility.
If the film is too narrow, increasing thickness increases tension
and accelerates failure.

Soil, Organic & Microplastics
Does compostable mulch leave residues in the soil?
No.
Compostable mulch is designed to biodegrade into:
• water
• CO₂
• biomass
No persistent plastic residues remain.
This biological conversion is the difference between
true biodegradation and plastic fragmentation .
Why does this matter for soil health?
Organic farming is about what remains in the soil.
Polyethylene fragments into microplastics.
Those particles persist and accumulate.
Compostable mulch does not.
▶ Understand microplastics in agriculture
Technical Limitations
Are compostable films suitable for fumigation?
No.
Compostable films have lower gas-barrier performance
than polyethylene.
They are not recommended for high-barrier fumigation applications.
Storage & Handling
Does storage matter?
Yes.
Compostable mulch is biologically active material.
For best performance:
• Store in a cool, dry place
• Keep out of direct sunlight
• Keep in original packaging
Improper storage accelerates aging before installation.
Still have a question we didn’t answer?
If you’re asking, it usually means your setup doesn’t fit a standard answer —
and that’s exactly where getting the right recommendation matters most.
