One thing all of Western’s molded fiber horticulture containers have in common is they are made with recycled paper and will eventually biodegrade. The longevity of Western containers is determined by many environmental factors that can affect the container’s life in both positive and negative ways. It’s worth noting that most “best horticulture practices” will also contribute to the longevity of our containers.

​

Factors affecting the breakdown and biodegradability of our containers 

The wood decay organisms that break down and biodegrade molded fiber containers are naturally present in the environment, and in particular, are often found in soil, bark, and other organic matter. The life expectancy of Western’s nursery container will largely depend on horticultural practices and external factors that encourage the growth of those wood-decay organisms including: 

• Irrigation type — Excessive irrigation situations, flood tables, and sitting in puddles all should be avoided. 

• Substrate underneath the Container — Containers on coarse gravel, benches, or ground cover fabric with good drainage and air circulation will last longer than those in direct contact with the earth.

• Air Circulation — Generally speaking, good air circulation increases the service life of the container.

• Soil Composition and Fertility — Avoid using high-nitrogen fertilizers or soil supplements that might stimulate the breakdown of organic matter.  Excess use of these products may shorten the lifespan of Western’s containers.

• Waxing of Containers — Select Western containers are sold as fully waxed-permeated or have a waxed rim and base. The addition of wax increases the service life and adds durability and strength to our containers. A wax barrier bottom can be applied to our unwaxed horticulture containers for a modest charge.

• Burying the pot in the soil — The same factors necessary to break down organic matter are essential to biodegrade Western horticultural containers. Soil temperature, moisture, fertility, and microbial activity all influence how quickly Western horticulture containers will biodegrade in the soil.

Proper Storage of Western’s Products

Western recommends that unused horticulture containers be stored in an area protected from weather and direct sunlight. If outside storage is necessary, they should be stored covered on a pallet to keep them from direct contact with the ground and to allow air circulation. Covering with a plastic tarp will help to keep the plastic film used to package them from degrading under UV light, and provide protection from moisture. 

 

Customers storing Western containers should rotate inventory and use older stock first.
