@BobVance. Thanks Bob for looking up the older post on your fathers bagging peaches. Rather than hijacking the post I started a new one. I found some bags at Walmart that look to be small and comparable in size (6.5" x 3.25") (regular sandwich bag 6 1/2" x 5 7/8").
These smaller bags might be better for bagging smaller pears and apples like the Seckel pear and Yates apple. I have a few of these two fruits this year and I will note the mature size.
Are you cutting off the corners or poking holes in the bags? I found a bad ripped open the other day.
My first year I cut only the corners and the second year I cut the corners again and also cut a few more spots on the bag. Several of the bags had excess moisture buildup in year one and two and I lost a few pears and apples. This year I made a temporary drill form that had small holes spaced about 3/4" apart. My opinion is that the extra holes helps with eliminating the moisture from the bag. I bagged about 250 apples and pears with almost no moisture issues yet. I have had about 5 bags pushed open and I think this is from not getting the zip closed properly. I tried punching the holes with a nail but they tend to close back up. I drill about 25 bags at a time so it doesn’t take long. I only had one plum bagged this way and it had no issues. Bagging takes a lot of time to do but it is still the only method for me to get near perfect fruit without pesticides.
I cut the corners and caught a bunch of plum curculio sneaking through the open corners.Had a big problem with moisture in the bags also.
The drill bit I used is smaller than the PC so I think I will be OK on that part. Hope I have a few nectarines in 2017 to give my improved bags a real test.
