pp: 323-333

The Question Box session convened at 7:40 p.m. in the Ontario Room. Mr. David Patterson was moderator.

DAVE PATTERSON MODERATOR: I'm delighted so many are here so early. I worried for two days that we wouldn't have enough questions; now I'm worried that we have so many we won't be able to cover them all. Without introductions of any kind I'm going to start right off with an easy question. What is the procedure for rooting Pinus strobus?

SID WAXMAN: I'm not going to give any recommendations as such but there are individual trees from which cuttings can be rooted. I know of one and have rooted cuttings taken in May wounded and treated with Hormodin 3 and Captan and placed in mist. They did take quite a while to root.

JOHN ROLLER: There are quite a few individual white pines that will root using Hormodin 2, mist and sand. I've noticed two Tanyosho Pines that in grafting it with moist peat around it, roots came out as quickly as the union is made. These were taken in early June from mature growth.
