| Propagule Collection: | Collected 12/6/02, Sequoia & Kings Canyon National Park, Ash Mountain, Buckeye Housing by M. B. Keeley | ||
| Propagule Processing: | Seed cleaning requires hand stripping dry pods off of hard-coated seeds. Gently blow off residual chaff. | ||
| Pre-Planting Treatments: | Hot water soaking treatment. 200F water is poured over seed to crack seed coat. Seed is left to soak in water overnight, then near boiling water is again poured over seed & left to soak. Continue to soak seed in fresh water for four more days, allowing seeds to imbibe water. Refresh water each day. Floating seeds are not viable and should be removed. Plant immediatly after treatment. Germination should occur within a couple of weeks. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Seeds are planted in 5%bleach-sanitized 2 1/2" deep nursery flats, filled with sterile well-draining soiless mix. (Suggested 1:3 parts perlite to soil mix) Neither orgainic nor inorganic fertilizers of any type should be in the soil. Keep seeds moist until well germinated, then reduce watering-- watering when soil is dry. | ||
| Establishment Phase: | Transplant immediately from flats into sanitized pots when two true leaves unfurl. Protect from rodents. Seedlings are subject to pythium and phytophthera, so, light applications of systemic Subdue fungicide are effective. Transplant directly into deep pots approximately 2 1/2" w x 8" h. Add 1/2 recommended dosages of time-release-balanced fertilized. | ||
| Length of Establishment Phase: | Approximately 2 months | ||
| Active Growth Phase: | Thereafter, water when almost dry only. Stop fertilizing by late spring and over the summer | ||
| Length of Active Growth Phase: | 1 1/2 years | ||
