Dr. Huey is a tried and true rootstock, and it is easy to root and easy to get buds to take.

There are all kinds of variables with rootstocks -- how long lived they are, whether the roots have a tendency to stay shallow (like fortuniana) or dig through clay (like Dr. Huey), how well the grafts take and how easily the first cambium layer of the stem lifts up from the stem to allow you to do the graft without tearing it. You just have to try to find out. I sometimes use my soon-to-be-discarded seedlings as rootstocks -- the ones that decided to be once-bloomers, for example, so I can vouch for the results being all over the place. There is a wide range of variables.

My favorite root stock is one called Pink Clouds -- I have yet to find any fault with it. It is what Ralph Moore's operation (and now Burling Leong) used.

Hi- budding roses is easy and fun, once you get the hang of it. But be careful- learn to do all cuts away from you, not towards you. This makes it tougher at first, but will save you a fair bit of spilled blood. I'm quite serious.

Lux, Pink Clouds is Burling's preferred stock as she says it remains ready to bud much of the year. Her Chip Budding method Donald shared above is particularly suited to it. Being mainly multiflora, it roots very easily. You need to root it this year for budding next. I can happily share cuttings with you if you need/want them. It's a largish, often once flowering climber with potential for repeat in good circumstances. Private message me if you'd like cuttings. Priority Mail gets things from El Lay to NorCal (and vice versa) in two to two and a half days. More than you would ever want will fit in a small Priority box. I just budded to some last week and they appear to be doing fine.

Another I like very much is using Cardinal Hume as under stock. It roots as easily as Pink Clouds and has accepted everything I've put on it. To hedge my bets, I budded the wood I received to both Pink Clouds and Hume, as well as tried rooting the remaining material. Normally, rooting here in the heat doesn't work, but I massaged it a bit, using seed starter mix instead of potting soil. I placed the pot in filtered direct sun for the morning hours. They're nearly two weeks old and still green and plump. The largest one actually has swelling buds. But, if you'd like either or both of these stocks to play with, I'll be happy to share. A main issue to keep in mind is, match the guage of your bud wood with that of the stock. A bud from an inch thick stem won't work on a half inch thick stock. You can do the reverse, but the stock has to be at least as thick as the bud stick or the bud won't make sufficient contact to callus. Kim
