Spring is when I do most all of my cuttings. It gives me the longest amount of time for them to grow before they have to endure my winter. I've found most all my HTs, flories and minis will root well at this time of year.

I do all kinds of roses in June.

I do all mine in spring and early summer, as soon as I can get semi-hardwood cuttings from my Austins, Bucks and other shrub roses and HTs.

Madame Alfred Carriere, and Lady Banks root like weeds. Most of the antiques root fairly easy.
