For the field-chilling study, a biophenometer was placed in the field to measure chill, and ten 12-node stem cuttings of each cultivar were collected at 100-lwur intervals of chilling up to 1000 hours below 7'C and placed under intermittent mist. You donât have to wait months to know whether or not you were successful.

Roots had significantly lower Ca tissue concentrations than shoots in both cultivars, and Ca tissue concentrations tended to be higher in the mid-portion of the shoot than in the basal or apical sections. Stem cuttings of baldcypress clones were rooted under envi ronmental conditions normally used for Douglas-ir cuttings. The method consists of collecting coppice sprouts that are just beginning to harden and keeping them constantly moist while 2-leaf-pair cuttings are prepared and end-dipped in rooting hormone.

Air layering, ground layering, and stooling was touched upon in reason #6 of 'Why You Need Intermittent Mist'.

Intermittent mist is like hiring a full time nanny for your softwood cuttings. After four or five days you can water them less often, but still quite frequently. This suggests that treatments such as shading, which increase plant cutting survival prior to rooting, but which also reduce photosynthesis, could likely be used prior to root formation without negative effects on rooting (…). Paclobutrazol markedly decreased flower stem length. Wanted! Whether you chose the ever popular red poinsettia or any of the many new colors such as white, pink, salmon, yellow, marble, orange, or jingle bells, this is a wonderful holiday plant that can sit on a table, be trained as a small tree, or be placed in a frame with 20-50 other poinsettias to form a magnificent huge poinsettia Christmas Tree.

The faster flowering and most plants flowering were obtained after five weeks of cooling at 10 degrees C under a 16 h photoperiod using pre-rooted rhizomes. The 23-year old clones rooted best (58%) in the wettest area of the root ing bed (50% moisture content).
