Houzi..Yes the girls are very good and very helpful, think that's why i like buying my young grafts from them, always good healthy stock Dick vm still does alot of the grafting for them, so you know it's going to be done right. Went in the early part of April just when the grafts were leafing ,but like going about now so you can see better the form and growth rate. So many grafts to choose but bought another 'Amber ghost' and 'Olsens frosted strawberry' then two new ones 'Sister ghost' and 'Autumn glory' been after one of these for a while looks very impressive lovey large leaf. Top left Autumn glory, Top right Amber ghost, B/l Sister ghost, B/R Olsens frosted As you stated they have lots of new cultivars,which one were you looking for? and i have never seen so many Hana Matoi's before dozens of them, nearly bought one but just couldn't pick one that i liked enough in form,will have another look when i go again in September. Re your potting mix must admit i tend to use peat moss, bark and no 3 and mine seem to like this alot and over the years they are all growing well.
