Would you like to grow your own apples? Add to the variety of apples you already have? Try growing a dwarf or semi-dwarf variety?

The Harvard Historical Society invites you to learn the basic techniques of grafting apple trees, with plenty of time for hands-on practice. Denis Wagner, horticulturist and commercial apple grower for 18 years, will offer a grafting program on Thursday, March 26, at 7 p.m. and again on Saturday, March 28, at 1 p.m., both at the Historical Society, 215 Still River Road.

The workshop is free, and you can bring your own knife and apple scion wood.

Or you may purchase a grafting knife ($15) and apple rootstocks ($4 each) from Wagner.
