| Stock Type: | Deepot 40 | ||

| Target Specifications: | Height: N/A<br> Caliper: N/A<br> Root System: Firm plug in container. | ||
| Propagule Collection: |
Seeds are collected between June 20th and November 15th. Mature pods turn dark brown and begin to open at maturity. Seeds are tiny, light grey to brown and slightly spongy at maturity. |
||
| Propagule Processing: |
Seed Cleaning:Rub pods over sieve and let seed fall through. Storage Conditions: Seeds are kept dry and stored in a refrigerator. |
||
| Pre-Planting Treatments: | Soak overnight in fresh water. Cold stratify at 40F in ph neutral peat for 3 weeks, or until seeds start to germinate. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Fully Controlled Greenhouse. Sowing Method: Transplanting Germinants. 4 grams of seeds are sown per flat containing Sunshine Mix #4 Aggregate Plus (peat moss, perlite, major and minor nutrients, gypsum, and dolomitic lime). Seeds are mixed with media to sow and are surface sown. Flats are watered in with an automatic irrigation system. Seeds are sown on June 1st. % Germination:50% |
||
| Establishment Phase: |
Seeds germinate 14 days after sowing. Seedlings are transplanted 14 days after germination to individual containers 40 cu. inch (Deepot) containing standard potting mix of peat moss, fir bark, perlite, and sand. Transplant Survival averages 50%. Transplant success is highly dependent on root mass at time of transplanting. To encourage, large roots in the flat, allow seedling to grow until root ball is well formed, and at least 2 inches long and 1.5 inches wide. Seedlings should be thinned in flats to 1 per square inch. |
||
| Length of Establishment Phase: | 1 month | ||
| Active Growth Phase: |
Castilleja species are hemi-parasitic. They depend in part on other plants for nutrients, particularly in low nutrient substrates. Fertilize with nutricote immediately after transplanting and every 3 months thereafter. Cut back tops 2 months after transplanting; leaving at least 5 nodes. |
