An update to my previous post.
The picking season for WP this year was a full month (in zone 6/7), from the second week of July to the second week of August.
As the apples’ ripening season overlapped with raspberries (mostly Polka) and aronia (mostly Viking) I’ve prepared serious quantities of low sugar, high aroma jam. That should tide us over even we get two consecutive years of late frosts agin
Even when WP is cooked on its own the pulp still turns out red - seemingly the red flush just under the skin is sufficient for this.
Having been picked, the apples would stand outside on a wooden table for a week or two without going bad. I was not experimenting with the time, this is just how long it took to process the waiting queue
There was, amazingly, no watercore despite the huge quantity of apples. It used to happen before. In my understanding watercore is related to a deficiency of calcium - our low pH soil and an abundant crop would naturally lead to that; so the absence was a surprise. Possibly it could be explained by the fact that the tree is grafted on a seedling and is now 10 years old (so it has a strong and mature root system).
Normally watercore is the only recurring problem I notice on our WP. No scab or at least no scab in a way that would affect the fruit. Leaves may sometimes look kinda tired and spotty but the fruit is always Snow white - class. Nice fragrant blossoms.
