Question
Tom,
Good Afternoon!

How do I start a cutting from a Japanese Maple tree?

Thanks!

Answer
Hi Bob,
Thanx for your question.  I would take cuttings from new growth (the green stems) and take all of the leaves off except for the last 2 or three.  The cuttings should be at least 6 inches but no more than 8 inches long.  Make the cutting at an angle at a leaf axil (where the leaf meets the stem) and dip into a rooting hormone like Rootone which is available at most garden centers or nurseries.  Stick the cuttings into a moist (not soggy) soil less mix or perlite that is very moist and make sure the cuttings do not touch each other.  Seal inside a plastic bag to keep humid but allowing lots of light.  Protect from direct sunlight as this time of year it will cook the cuttings.  So, you'll have to keep the cuttings under a 40-watt shop light.  Make sure the bottom stays at least 70 but no more than 75 degrees F.  Rooting will take place in about 8 weeks.  Check by taking a pencil and gently digging around the cutting.  If you see a lot of white strands your cutting may be ready to plant in separate pots or directly out in the garden whichever you wish however, the cutting must be gradually acclimated by placing them in a place out doors which is safe from extremes in temperatures, sunlight, rain and wind for 7 to 10 days.  After that you may plant them outdoors as long as there are at least 30 days before the first hard frost.  I hope this helps.
