About 4 weeks ago, I went and grabbed about 50 cuttings - 15 inches long of red os dogwood. I threw them in a large white pail of about 5 inches of water and stuck it in the basement. Last week I checked and there are the beginnings of fruiting and leafing out - but im trying to get roots. 2 questions A) should I cut the new growth - so the energy can go to the roots

B) how long before they start to root? I see swollen bumps along the cutting under the water is that where they will start - on these bumps.
