| Propagule Collection: |
Collecting cuttings: For collection of native plants to propagate by cuttings, you will need: gloves, clippers, zip-lock or plastic garbage bag for collection, and some water. Collect plants from the site, taking care to take only what you need. Collect from areas that have a large enough population so that damage will be minimal. Gently pull or cut strands of plants from main patch. Place in trash bag or plastic bag. Add a small amount of water to bag and store in a dry, cool, shady area. |
||
| Propagule Processing: | Cuttings can be stored overnight, but immediate propagation following collection is best. | ||
| Pre-Planting Treatments: |
For cuttings, use green tip, 5-6 " inches in length, remove lower foliage, keeping tip and new leaves. No rooting hormone is necessary. Place in medium under mist. Work in a shady area once back in the nursery. Use clean 3 «" pots arranged in tray. Use well drained potting mix. Fill pots about 1/3 full. Cut plants into desired lengths. Fill the rest of the pot with potting mix. Water daily. Cuttings need to be kept in a moist humid environment. In the nursery, this can be achieved by misting plants several times during the day to keep them moist. |
||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
The nursery's irrigation system is comprised of sprinkler heads which are manually operated. The sprinklers are misters and should be maintained so that they flow freely. Potted plants are watered daily, either in the morning or the evening. Potting media is Sunshine Mix potting soil, and is used in a 2 to 1 or 3 to 1 (v:v) potting soil to sand ratio. Diseases and insects are controlled by removing them manually off plants, sticky traps or using a solution of soapy water. Be sure to rinse soapy solution off plants after a few hours. Row covers physically prevent insects and birds from landing on plants. |
||
| Establishment Phase: | Plants will form roots in 2 to 3 weeks. | ||
| Length of Establishment Phase: | 2 months | ||
| Length of Active Growth Phase: | 4 months | ||
| Other Comments: |
Pests and diseases: Row covers have been used as a precaution to prevent injury from canaries and other pests. |
