Easy Fall Propagation Techniques
As a home gardener, fall should be a very special time for you. Fall is the best season of the year for plant propagation, especially for home gardeners who do not have the luxury of intermittent mist. The technique that I am going to describe here can be equally effective for evergreens as well as many deciduous plants.
The old rule of thumb was to start doing hardwood cuttings of evergreens after you have experienced at at least two hard freezes. After two hard freezes the plants are completely dormant. However, based on my experience it is beneficial to start doing your evergreen cuttings earlier than that. So instead of doing by the book hardwood cuttings youíre actually working with semi-hardwood cuttings.T
he down side to starting your cuttings early is that they will have to be watered daily unless you experience rain showers. The up side is that they will start rooting sooner, and therefore are better rooted when you pull them out to transplant them.
To prepare an area in which to root cuttings you must first select a site. An area that is about 50% shaded will work great. Full sun will work, it just requires that you tend to the cuttings more often. Clear all grass or other vegetation from the area that you have selected. The size of the area is up to you. Realistically, you can fit about one cutting per square inch of bed area. You might need a little more area per cutting, it depends on how close you stick the cuttings in the sand.
Once you have an area cleared off all you have to do is build a wooden frame and lay it on the ground in the area that you cleared. Your frame is a simple as four 2 by 4ís or four 2 by 6ís nailed together at each corner. It will be open on the top and open on the bottom. Just lay it on the ground in the cleared area, and fill it with a coarse grade of sand.
This sand should be clean (no mud or weed seed), and much coarser than the sand used in play box. Visit your local builders supply center and view each sand pile they have. They should have different grades varying from very fine to very coarse. You donít want either. You want something a little more coarse than their medium grade. But then again itís not rocket science, so donít get all worked up trying to find just the right grade.
Once your wooden frame is on the ground and filled with sand, youíre ready to start sticking cuttings. Wet the sand the day before you start, that will make it possible for you to make a slit in the sand that wonít fill right in.
In this propagation box you can do all kinds of cuttings, but I would start with the evergreens first. Taxus, Junipers, and Arborvitae. Make the cuttings about 4" long and remove the needles from the bottom two thirds of the cuttings. Dip them in a rooting compound and stick them in the sand about an inch or so. You can buy rooting compounds and all kinds of other propagation supplies on-line at www.homehavest.com Jeff Edwards is the owner of this website, and he has always been great to do business with.
When you make the Arborvitae cuttings you can actually remove large branches from an Arborvitae and just tear them apart and get hundreds of cuttings from one branch. When you tear them apart that leaves a small heel on the bottom of the cutting. Leave this heel on. It represents a wounded area, and the cutting will produce more roots because of this wound.
Once the weather gets colder and you have experienced at least one good hard freeze, the deciduous plants should be dormant and will have dropped their leaves, and you can now propagate them. Just make cuttings about 4" long, dip them in a rooting compound and stick them in the bed of sand. Not everything will root this way, but a lot of things will, and it takes little effort to find out what will work and what wonít.
This is a short list of just some of the things that root fine this way. Taxus, Juniper, Arborvitae, Japanese Holly, Blue Boy/Girl Holly, Boxwood, Cypress, Forsythia, Rose of Sharon, Sandcherry, Weigela, Red Twig Dogwood, Variegated Euonymus, Cotoneaster, Privet, and Viburnum.
With some cuttings it helps to apply some bottom heat for a period before sticking them in the sand. Iíll address an easy way to do that in another article.
Immediately after sticking the cuttings thoroughly soak the sand to make sure there are no air pockets around the cuttings. Keep the cuttings watered once or twice daily as long as the weather is warm. Once winter sets it you can stop watering, but if you get a warm dry spell, water during that time. Start watering again in the spring and throughout out the summer. The cuttings should be rooted by late spring and you can cut back on the water, but donít let them dry out to the point that they burn up. By fall you can transplant them to a bed and grown them on for a year or two, or you can plant them in their permanentlocation.
This technique takes 12 months, but it is simple and easy.
