Do you have any information on the use/success on the out planting of container seedlings grown in RootMaker II containers directly in the field for conservation/reforestation type projects?

Tree seedlings in RootMaker® II propagation containers are routinely taken to the field when they are 12 to 16 inches tall and 3 to 4 months old. This has been done by hundreds of nurseries across the country. Most do fall planting – September or October and some have drip irrigation and others do not. (Drip irrigation assures nearly 100% survival. But even without drip irrigation, the success rate is quite high, except for the occasional severe drought immediately following planting). The primary reason for planting tree seedlings at a larger size is that in the small growth stage, telling seedlings that will make winner trees from culls is tough and the cull rate may be as high as 25 to 30% or more for the oaks. In one gallons, the cull rate drops to 7 to 10% and with 3 gallons to 2 to 3%.
