Propagation Goal:
plants

Propagation Method:
vegetative

Product Type:
Container (plug)

Stock Type:
490 ml containers

Grow Time:
5 Months

Target Specifications:
Stock Type: Container cutting
Height: 4 cm
Caliper: n/a
Root System: firm plug in container.

Propagation Collection:
Vegetative Propagation Method: Pre-Rooting
Type of Cutting: Herbaceous stem cuttings taken in late August. Cuttings are 2 to 4 cm in length.

Propagation Processing/Propagule Characteristics:
Cuttings are stuck in rooting medium immediately after collection.

Pre-Planting Propagule Treatments:
Succulent stem cuttings can be taken any time of year. Cuttings are treated with 1000 ppm Hormex rooting powder and struck in moist sand. Intermittent mist is not necessary. Cuttings generate roots along the stem in 2 weeks.
Rooting %: 100%

Growing Area Preparation / Annual Practices for Perennial Crops:
Greenhouse and outdoor nursery
Use a well aerated rooting medium of 50% sand and 50% perlite. Trays are kept in a greenhouse and watered by hand to keep rooting medium evenly moist. Because this is a succulent, frequent intermittent mist should not be used.

Establishment Phase:
After cuttings are well rooted in 2 to 4 weeks, they can be moved to the outdoor nursery.

Length of Establishment Phase:
4 weeks

Active Growth Phase:

Growing medium used is 6:1:1 milled sphagnum peat, perlite, and vermiculite 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 1 gram of Osmocote and 0.25 grams of Micromax per container.
Cuttings were irrigated after potting.

Length of Active Growth Phase:
12 weeks

Hardening Phase:
Plants are fertilized with 10-20-20 liquid NPK at 200 ppm during August and September. Plants were given one final irrigation prior to winterization.

Length of Hardening Phase:
4 weeks

Harvesting, Storage and Shipping:
Total Time To Harvest: 5 months from cuttings
Harvest Date: August
Storage Conditions: Overwinter under insulating foam cover and snow.

Length of Storage:
5 months

Guidelines for Outplanting / Performance on Typical Sites:

Other Comments:
Seed Propagation: Hand collect mature follicles when they begin to tan and split open at the top. Seeds are brown at maturity. Seeds are collected in late August at high elevations.
Seeds are cleaned using a hammermill, blower, and screens.
Seed longevity is unknown.
Seed dormancy is classified as nondormant for many temperate Sedumspecies.
Seeds/Kg: unknown
