From 10 or 20 feet away, you would never know anything was amiss.

But up close, there is minor leaf spotting and some whitish areas, perhaps mildew.

The trunk and older branches are rampant with moss and lichen, apparently not a problem.

The fruit is subject to brown rot, this is completely random. Some fruit rots before

becoming ripe and some fruit can store for several weeks post-ripe with no rot.

10-15% of crop lost this way. Usually significant amount of flesh dark mottling/specks,

but have seen none this year. Cracked fruit not uncommon, may or may not rot.

Infrequent scabs on surface do not affect flesh.

Pests: A few bird pecks, infrequent human removal of a fruit, found up the street

with one bite taken (good nickname for quince would be fool's apple or fool's pear).

Any year now squirrels will figure this tree out and then I will have a real problem.

I would say on average, 2/3 of the crop is perfectly usable. The only attention I give the

tree is summer water, autumn harvest, and winter pruning.
