Container (plug)

3 L containers

15 Months

Height: 30 cm
Caliper: 7 mm
Root System: firm plug in 3L(1 gallon) container.

Cuttings were collected in May and June from healthy field plants.
Type of Cutting: Spring semi-softwood and softwood stem cuttings.

Cuttings were kept in refrigeration and moist prior to striking in mistbed.

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.

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.

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.

8 weeks

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.

16 weeks

Plants were fertilized with 10-20-20 liquid NPK at 200 ppm during September and October and given one final irrigation before overwintering.

6 weeks

Total Time to Harvest: 15 months
Harvest Date: September
Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
