Thanks Pierre for that. We have used similar stuff in the vineyard to increase soil activity. More homework on " mycorhizal fungi, but all is good.
Congratulations, Peter! Those are the only seedlings from Linda, either way, I’ve ever known of and they’re quite nice! Ralph NEVER got ANYTHING from her.
A few months back now, I had planted a R.multifloraXOP seedling in my mom’s garden (the local soil is a bit sandy - unknown pH…the soil had been amended quite generously with composted sheep manure, which nearly every rose I have given this, loves!).
Sooo, at about ten months old, in mid-summer all of a sudden this seedling started to develop yellowing of many of the older basal leaves and some of its thinner/older canes started to yellow from the base up. It had previously been a fairly vigorous grower.
To be honest, I don’t really know what chlorosis looks like, but I assumed it had this condition and culled it.
Did it look anything like any of these? Chlorosis
Kinda hard to say Kim, next time I’ll try and post a picture to help in the discussion of such things.
That should help. Thanks.
Just for kicks and giggles I germinated some open pollinated seeds of Showy Pavement, Schneezwerg and Blanc Double de Coubert this year. Almost without exception the Showy Pavement seedlings are all showing signs of chlororsis and a good number of the Schneezwerg seedlings are also, so I’ll probably cull them. The BDdC seeds took longer to germinate so they’re much smaller, but they’re looking very green so far. So that kind of verifies what I remember about which plants had chlorosis. It’s too bad I didn’t grow any Darts Dash seedling this year. It would have been nice to see if whether or not those seedling get it also.
