Family Scientific Name: Caprifoliaceae
Family Common Name: Honeysuckle family
Scientific Name: Lonicera utahensis Wats.
Common Name: Utah Honeysuckle
Species Code: LONUTA
Ecotype: Lodgepole Forest, Many Glacier, 1500m elev.
General Distribution: L. utahensis occurs from southern B.C. east to Alberta and south to California, Montana, Wyoming, and Utah. This species occurs in a variety of forest habitats that are vernally moist.
Propagation Goal: plants
Propagation Method: vegetative
ProductType: Container (plug)
Stock Type: 3 L containers
Time To Grow: 15 Months
Target Specifications: Height: 30 cm<br> Caliper: 7 mm<br> Root System: firm plug in 3L(1 gallon) container.
Propagule Collection: Cuttings were collected in May and June from healthy field plants.
Type of Cutting: Spring semi-softwood and softwood stem cuttings.
Propagule Processing: Cuttings were kept in refrigeration and moist prior to striking in mistbed.
Pre-Planting Treatments: Cuttings were re-cut and terminal buds were removed. Cuttings were given a 2 minute Domain fungicide bath. Cuttings are treated with 2000 ppm liquid IBA rooting hormone.
Cuttings were cut into 15 centimeters length with an average caliper of 7mm.
Rooting %: 16% to 75%
Cuttings collected at leafbud break in early spring had the highest rooting percentage. Fully dormant hardwood cuttings may yield higher rates of rooting.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 The outdoor mistbed has automatic intermittent mist that is applied at 6 second intervals every 6 minutes. Too frequent misting will result in leaf and stem rot.Bottom heat is maintained at 21 C with heating cables 12 cm beneath rooting media. Rooting media is 50% perlite and 50% sand. Mistbed is covered with shadecloth during rooting.
Establishment Phase: Cuttings were well rooted after 8 weeks and were transplanted into 3L (1 gallon) containers using 50% 6:1:1 spaghnum peat, vermiculite, perlite and 50% sand with Osmocote controlled release fertilizer(13N:13P2O5:13K2O; 8 to 9 month release rate at 21C) and Micromax fertilizer (12%S, 0.1%B, 0.5%Cu, 12%Fe, 2.5%Mn, 0.05%Mo, 1%Zn) at the rate of 4 grams of Osmocote and 2.0 grams of Micromax per container.
Length of Establishment Phase: 8 weeks
Active Growth Phase: Growth is very rapid following transplanting. Plants were fertilized bi-weekly with 13-13-13 liquid NPK at 100 ppm. Plants were multi-stemmed and root tight in 1 gallon containers in 4 months. Plants reached reproductive maturity 1 year after germination in the nursery.
Length of Active Growth Phase: 16 weeks
Hardening Phase: Plants were fertilized with 10-20-20 liquid NPK at 200 ppm during September and October and given one final irrigation before overwintering.
Length of Hardening Phase: 6 weeks
Harvesting, Storage and Shipping: Total Time to Harvest: 15 months
Harvest Date: September
Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
Length of Storage: 5 months
