| Family Scientific Name: | Rosaceae | ||
|---|---|---|---|
| Family Common Name: | Rose Family | ||
| Scientific Name: | Rosa woodsii Lindl. | ||
| Common Name: | Woods rose | ||
| Species Code: | ROSWOO | ||
| Ecotype: | Numerous Glacier National Park seed sources. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Bareroot (field grown) | ||
| Stock Type: | 2+0 and 3+0 bareroot | ||
| Time To Grow: | 2 Years | ||
| Propagule Processing: | Store fruit (hips) in a cool humid location, such as a refrigerator, until processing. Dehydrated fruit requires soaking in water prior to maceration. Fresh fruit (hips) process easily in a DybvigT macerator. Rinse depulped seeds several times in a bucket to float off debris and light seeds. Spread clean seed on kraft paper and dry overnight in a warm location. Additional cleaning is seldom necessary, although a fanning mill is occasionally needed to remove fine debris. | ||
| Pre-Planting Treatments: | . Mid-summer field planting substitutes for the warm moist stratification requirement for bareroot production. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Rototill the seedbed to break up clods and level the site. Soil moisture needs to be such that rototilling leaves behind a fine, fluffy seedbed. Lightly firm the seedbed with a roller or packer prior to sowing if the soil surface is too soft. Sow 25 to 50 seeds per linear foot to a depth of 0.25 to 0.5 inches. We maintain a 4-ft wide bed (5-ft between beds), and plant 3 to 4 rows of seeds per bed depending on production interval. We cover our seeds with excelsior mat to maintain soil moisture and minimize animal predation. We fall sow fresh Woods' rose in October or November. Germination may occur the following spring, but usually occurs the second spring after sowing. This response supports reports that a warm moist stratification of 45 to 90 days followed by a 4- to 5-month cold moist chilling is needed to break dormancy. Under intensive management, 1-0 stock is adequately sized for outplanting the next year, although we prefer to produce and use 2-0 stock. Bareroot Woods' rose grown as 3-0 is usually too large for efficient handling and planting. It may be possible to collect and clean Woods' rose in late summer, warm moist stratify in the greenhouse, and then fall sow to meet the cold chilling requirement. | ||
| Harvesting, Storage and Shipping: | Bareroot Woods' rose is harvested as soon as the ground thaws in early spring. A "U" blade mounted to a 3-point system on the back of a tractor is used. Beds are undercut in two directions (lengthwise) prior to using the blade to lift the plants. Bundles of 10 to 50 plants are tied together, trimmed to a uniform size, then the roots packed in moist sphagnum or peat moss wrapped in plastic. The plants are stored in a walk-in cooler maintained at 34 to 37øF and 80+% relative humidity until needed and then shipped in heavy wax coated boxes as priority ground mail early in the week. Containerized stock is normally delivered directly to GNP, but shipping of fully dormant plants as described for bareroot material should prove equally successful. | ||
| Length of Storage: | Fully dormant bareroot plants store well for several weeks at 34 to 37øF and 80+% relative humidity. | ||
| Other Comments: | An excellent species for bareroot production. | ||
