Growing Area Preparation/
Annual Practices for Perennial Crops:

Container Type and Volume: Cuttings are started in large 14” w x 22” l x 4” d flats; once rooted, they are transferred to quart containers and possibly half-gallon, depending on planting needs.
Growing Media: Cuttings are stuck in straight perlite. Transplants are grown in woody mix (3.8 cu ft. bale Sunshine #1, 4 cu. ft. of pine bark mulch, 20 oz. Nutricote and approximately 20 oz. endo-mycorrhizae).
Hardening Phase: Hardening Phase: Once cuttings are transferred to quarts in late summer, they are moved outside to a shade house for acclimation.
Harvesting, Storage and Shipping: Total Time to Harvest: It takes about 1½ years to get a quart container ready for the field.
Storage Conditions: Container plants are stored in a cold house @ 40º F for the winter; containers are periodically watered to prevent dehydration.
Length of Storage: Storage Duration: 2-4 months.
Outplanting performance on typical sites: Outplanting Site: Shenandoah National Park, George Washington Memorial Parkway, National Plant Materials Center.
Outplanting Date: Spring.
Other Comments: Vegetation Propagation Method: Softwood cuttings are taken in the last week of June, either at the Parks or from stock plants established at the NPMC. Cuttings are trimmed to approximately 6 inches with one pair of leaves at the top, dipped in a 1:5 solution of Dip n Grow, and stuck in flats of perlite under mist in the greenhouse. Cuttings root in a few weeks and are then transplanted to quart containers with a mix of Sunshine Mix #1, fine pine bark chips, Nutricote, and endomycorrhizae.
