Why do you need to
Why do you need to learn how to propagate Junipers from cuttings rather than from the seeds they produce? Well, Juniper seeds have a dormancy requirement; if planted, it will take 2 years to grow - they require a warm period, then cold period, then warm & cold again. Using cuttings is not only faster; it provides uniformity in color and texture because you're cloning plants whose qualities you're already familiar with. In this video, Eric walks through the propagation process step-by-step. He references Dirr's "The Reference Manual of Wood Plant Propagation" as a great encyclopedic reference.

00:02:57 One challenge is finding the material to take the cuttings from. Eric shows examples of the type of growth that is useful for propagation.
00:05:42 Cut off small 3" branches and make small cuttings with 3/4" stem to stick into the soil. Eric explains the difference in growth (speed and vigor) between cuttings from a less healthy "mother" plant and a very healthy one.
00:07:53 The ideal scenario is to start with a cutting 3-4" long with a 1" stem that is about the size of a matchstick, and definitely no wider than a pencil.
00:09:01 A few examples of strong and weaker cuttings.
00:11:29 "Heel cutting" is using a side shoot. This only roots well when the cutting is relatively young. You can cut a long healthy stem into an upper and lower section for 2 cuttings.
00:12:56 Process of sticking cuttings. Do you need a grafting knife or can you use sharp scissors? Eric has found that the difference in "take" rate is neglible for small cuttings, so having a nice sharp pair of scissors should be sufficient.
00:14:37 Rooting hormone is a synthetic product that is derived from a natural hormone in plants. Eric uses Hormex #3 and #8 and explains that the difference is in concentration, because some plants burn if it's too high and others don't react if it's too low. For Junipers, Eric uses #8.
00:15:43 Liquid vs Powder? Eric using powder because after dipping and sticking the cuttings in the media, powder enables more time for the hormone to take action.
00:16:08 Before sticking, Eric recommends dipping cuttings with fungicide (zerotol).
00:16:35 The soil Eric uses is 80% perlite, 20% coco coir. He stacks cuttings in as close together as possible in the container, and explains that you can generally use any container except mesh-sided because that has a tendency to dry out too quickly. His preferred container is a 17" Anderson propagation flat which has a mesh bottom.
00:17:57 Aftercare; Eric propagates in the fall (we're in Northern CA) and leaves the container outside in a shady area for a few months, on top of a seedling heat mat. Heat on the bottom of the container warms the soil, which stimulates root growth.
00:19:33 Water - cool moist but not too frequent misting for Junipers.
00:20:12 Eric pulls apart a flat of cuttings from last year, separating them into three piles. The bigger cuttings have 3-4 times more roots and growth than the smaller cuttings.
