Just went to Costco (the Watford one in our case). Their bargain £11.99 fruit trees had nearly all gone, but they had a shipment of the most beautiful cherry trees. These were in 13.5 litre pots, and looked to be 3 years old, very vigorous and covered with buds.
They'd need to be planted out PDQ, of course. They were £22.99 each, which is quite expensive, so I thought I'd post this here rather than in the Bargains section. But if anyone wants a Stella, a Sunburst, or a Morello, then these look really superb.
Colt rootstock, BTW.
I quite fancy another sunburst... but I will stick to Gisella... :-\
