Research Supports PBH As Partial Pine Bark Replacement

Research from the Department of Horticulture at the University of Arkansas, Fayetteville, authenticates the use of PBH as a partial replacement for pine bark in nursery stock container media.

The research concludes that pine bark substrates amended with up to 40 percent PBH Nature’s Media Amendment will not decrease plant growth or increase the volume or frequency of irrigation for the production of container-grown spirea over one (25 weeks) and two (70 weeks) growing seasons, respectively.

Based on the research, pine bark-based substrates amended with up to 40 percent PBH retained physical properties that were generally within current guidelines for nursery container substrates after one or two growing seasons. Decomposition was not an issue.

The research substantiating the use of PBH Nature’s Media Amendment as a partial pine bark substitute comes at a time when growers have seen pine bark availability decline, prices rise and freight charges increase. PBH gives growers a sustainable, economical and readily available alternative for container-grown nursery stock production.

PBH consists of uniquely processed, lightweight and consistent parboiled rice hulls. It is OMRI Listed and registered by the Washington State Department of Agriculture. Suitable for traditional or organic production, PBH requires no land disruption or tree removal to produce. It is a product of Riceland Foods.

Canadian Sphagnum Peat Moss Association Announces Early…

According to an August 31 survey of members of the Canadian Sphagnum Peat Moss Association (CSPMA), whose members represent approximately 95 percent of all North American peat production, the peat harvest season has been adequate, but not strong, and could cause shortages and potentially higher transportation costs. Down To The Dirty Details The survey inquired about the status of CSPMA members’ 2015 Actual Harvest (including an estimate of what can be expected to be harvested for the remainder of the season) as a percentage of their 2015 Expected Harvest. The lack of a strong harvest overall may challenge peat availability. The Prairie Provinces (Manitoba 98 percent, Saskatchewan 88 percent and Alberta 94 percent), experienced early favorable weather conditions and a strong start to the year. This helped to minimize periodic, negative, weather-related conditions during the balance of the harvest season, and the harvest numbers are close to achieving the expected amounts. […]

How Bob’s Market And Greenhouses Improved Growing…

My father started our company 45 years ago growing bedding plants, mainly early season production and finished plants for our West Virginia market. It was in the early 1980s that we started growing earlier spring production and shipping materials to southern markets, and by the late 1980s, we also produced pansies for fall. We started using hydrogels when they first came on the market in the early 1990s and found that they really helped with our production by keeping plants healthier for these new markets. Over the years, we’ve grown to be a large young plant producer and have a sizable business growing finished plants in cell packs, 4 1/2-inch pots, 6-inch pots, gallon containers, hanging baskets, multiple sizes of large containers and large baskets for municipal use. Creating The Ideal Soil Mix With our old system, it took several workers to mix pre-made soil with slow-release fertilizers in cement […]
