Proper method to perform hemlock cutting?

17 years ago

So you hear it right. Last time, i have tried to perform hemlock cutting, but i failed. They were doing right until one day they started loosing their needles, all of them without showing any signs. How do you manage to perform your hemlock cutting? Oh it's eastern hemlock. The time i have tried these cutting, i put IBA on them put in potted soil. Is there any better way to perform cutting, it's perhaps the easiest and least expensive method to propagate hemlock!

Much easier by seed. Propagation by cuttings is difficult, = expensive. Do you have a full set of professional propagating equipment?

Cuttings:
"The preferred method for propagating hemlock cultivars, however, success is variable. Cuttings harvested from January to mid-February and placed over bottom heat (75 F) have been successful with most cultivars [The Plant Propagator 17(1):5 (1971); PIPPS 25:81 (1975) and 35:565 (1985)]. In other cases, cuttings consisting of two or more growth flushes and taken in October and November have rooted [PIPPS 21:470 (1971)]. A 5-second dip using NAA and IBA at 5000 ppm each has been most successful. The cuttings can be placed in an open bench or polyethylene chamber. Softwoods taken in July and placed under mist have also been successful. Wounding the cuttings may be beneficial. Treat the cutting base with 8000 ppm IBA-talc and Benlate (8:1, v/v).

Considerable variation also exists in rooting "witches' brooms". In one study, cuttings with 2 to 3-year-old wood at the bse from six, 5-year old "witches' broom" clones, early January, 2% IBA-quick dip, peat:perlite (1:1, v/v), rooted 40 to 100% in 4 months [PIPPS 35:555 (1985)]."

Thanks to both of you, that will be usefull.

Sadly, i don't have or own any professional propagation kit. Looking by the given method, it doesn't look easy at all to root.

Hopefully not all conifers are that hard to root, i am considering rooting xanthocyparis nootkatensis pendula who is easier to root.

In addition to what Dax mentions, according to "The Cultivated Hemlock" by John Swartley, etal, Don Smith used to take his cuttings after the spring growth hardened off but before the second flush started. He stuck them into a modified (somewhat deeper) Nearing Frame on the north side of a building and pretty much ignored them. So there are those who have had success at various times of the year. I have only tried January cuttings with miserable success. Miserable success? I guess that equates to glorious failure. Ã
