In the 2009 Bonsai Focus magazine, Issue #122, there is an article by Peter Thali on how the Indonesia’s Bali bonsai master, Gede Merta, used fusion technique to create large impressive ficus with spreading nebari from young seedlings. He did it in two stages: (1) using nails and tapes, 25 1½-year old seedlings were fused together to form the main trunk; and (2) after the main trunk has formed, 50 more 6-month old 24- to 32-inch long seedlings were added to the lower section to create taper; several of these seedlings were bundled together, wrapped with tapes and bent to form future side branches. Using this fusion technique and with Bali’s year-round tropical growing climate, the fused ficus quickly developed into a beautiful large bonsai with impressive nebari and thick branches. Please see the article for detail descriptions and photos.
