| Family Scientific Name: | Malvaceae | ||
|---|---|---|---|
| Family Common Name: | Hibiscus Family | ||
| Scientific Name: | Hibiscus tiliaceus L. | ||
| Common Name: | Gaal' | ||
| Species Code: | HIBTIL | ||
| Ecotype: | Yap Islands | ||
| General Distribution: | Gaal' is a pantropical, coastal strand plant that is found on muddy or sandy coasts, limestone rocks, mangrove swamps and inland along estuaries. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 3L (1 gal) polybag | ||
| Time To Grow: | 6 Months | ||
| Target Specifications: | Height: 20 cm<br> Caliper: N/A<br> Root System: Firm Root Plug in container | ||
| Propagule Collection: | Seeds are hand collected when woody capsules have matured and begin to split open. Seeds are brown at maturity. | ||
| Propagule Processing: | Seeds dry in paper bags in a warm, dry room. We clean the seeds by hand. | ||
| Pre-Planting Treatments: | Seeds are soaked in water to remove any inhibitors and to allow full imbibition of seeds prior to sowing. Seeds are sown into deep flats (1X2') and covered with composted leaf mold. We transplant viable germinants into containers as soon as the radicle emerges. Flats are checked for new germinants daily. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
The Yap Agroforestry nursery a year round growing season with periods of high rainfall. The facility is comprised of one large greenhouse, shade structures, and mist propagation beds, and an outdoor growing compound. All propagation environments are utilized at different stages of seedling growth to protect seedlings from heavy rains, and provide to temperature and shading variance during production. We irrigate all containers by hand, but are investigating a sub-irrigation system for the nursery. We use fertilizers if when they are available. |
||
| Establishment Phase: |
Seedlings are germinated in a greenhouse were they remain for 4 weeks. Flats and containers are watered by hand. After seedlings are well established and have at least 2 true leaves, they are transplanted into 3 L (1 gallon) polybags filled with a growing medium of 2:1:1 (v:v:v) sand, seaweed compost, and topsoil. |
||
| Length of Establishment Phase: | 4 weeks | ||
| Active Growth Phase: | Approximately 4 weeks after transplanting, seedlings are grown under a shadecloth during summer months. During months of intense summer heat, containers are watered daily with occasional deep irrigation to leach out accumulated salts. | ||
| Length of Active Growth Phase: | 12 weeks | ||
| Hardening Phase: | Irrigation frequency and duration is gradually reduced for 4 to 8 weeks prior to outplanting. Nursery stock is top pruned at this stage. | ||
| Length of Hardening Phase: | 4 weeks | ||
| Harvesting, Storage and Shipping: | Containerized seedlings are stored in the open growing compound until moved to outplanting site. | ||
| Length of Storage: | Variable; depends on outplanting date. | ||
