| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | Container Seedling | ||
| Time To Grow: | 0 | ||
| Target Specifications: | Height: N/A<br> Caliper: N/A<br> Root System: Firm plug in container. | ||
| Propagule Collection: |
Seeds are collected between July 1st and September 1st. Fruits grow close to the ground and are enclosed in papery bracts which become brown and dry at maturity. Seeds are hard,dull black pea-like seeds, about 3 to 5 mm in diameter at maturity. |
||
| Propagule Processing: |
Seed Cleaning: Storage Conditions: Seeds are kept dry and stored in a refrigerator. |
||
| Pre-Planting Treatments: |
The seed coat must be scarified prior to sowing so the seed can quickly imbibe water. Tumble in a rock tumbler with rocks for 24 hours, then check. Continue until the seed coat is obviously and deeply scratched. For small seed lots, use sandpaper to scratch the seed coat until the endosperm is visible (this will be pale compared to the seed coat). |
||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Fully Controlled Greenhouse. Sowing Method: Direct Seeding. Seeds germinate 15 days after sowing. Seedlings are sown in individual containers 2"x7" tubes (Deepot 16)containing standard potting mix of peat moss, fir bark, perlite, and sand. Seeds are planted 2 times the diameter to depth and are surface sown. Containers are watered in with an automatic irrigation system. Seeds are sown on July 1st. % Germination:50% |
||
| Establishment Phase: |
Seedlings are transplanted 15 days after germination to individual containers 2"x7" tubes (Deepot 16)containing standard potting mix of peat moss, fir bark, perlite, and sand. Survival rate after Transplanting: 90% |
||
| Length of Establishment Phase: | 1 month | ||
| Active Growth Phase: |
After seedlings are well established, they are moved to the shadehouse (30% shade fabric) for continued growth. Prune back 2 months after transplanting. Fertilize with 10 grains of Nutricote (NPK 13-13-13) 2 months after transplanting. |
