| Propagation Method: | vegetative | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 10 cubic inch containers | ||
| Time To Grow: | 16 Weeks | ||
| Target Specifications: | firm root plug with enough cohesiveness to hold potting mix together | ||
| Propagule Collection: | Leafy cuttings are collected in June or July. Cuttings should be firm, not soft and approximately 3/16 inch in diameter at a minimum. Cut stems below a node at a length to facilitate planting in the rooting media. It may be useful to trim one of the leaves off near the node to decrease the amount of space the cuttings occupy. | ||
| Pre-Planting Treatments: |
Treat with a 30 second or so fungicide drench prior to applying rooting hormone. Rooting hormone is applied to the fresh basal cut, 1/4 to 1/2 inch up the stem. We used .3% Indole-butyric acid rooting hormone as a powder. Cuttings were stuck in coarse perlite. |
||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
The indoor mist facility is set for 15 seconds of mist every 15 minutes. 24 hr/day 1000 watt metal halide light is used. Plants are rooted in 4 inch deep flats with bottom drain holes and bottom heat mats. The rooting media is kept at 75 to 77 deg F. Air temperature is kept around 68 deg F. | ||
| Hardening Phase: | Move plants from rooting mist to hardening mist, without bottom heat after plants have a minimum of 3 to 4 roots at least 1/4 inch long. Plant in potting mix that is well drained, such as Sunshine #4. Increase interval between mistings to harden plants prior to placing in general growth facility. Plants generally take about 90 days to produce an adequate plug. | ||
| Length of Hardening Phase: | 1 to 2 weeks in hardening mist | ||
