First time to use the organza bags. The ones I used were 5x7 very fine mesh. I decided that the Korean Giant might require a larger bag. All the ones that were 6x9 indicated that they were large mesh (Probably big enough for stink bugs. I went ahead and put on the 5x7. I don’t know how they managed to get the mesh so small. Time will tell how effective they are.
Does the string on the organza bags last ? You mentioned in other posts durability of the bags may be few seasons. I suspect the strings may break first, in which case I suppose you can throw them away or use garbage ties.
6x9 Organza bags from amazon.com have worked well for me, the mesh/weave is fairly “fine”. Around $0.14 per so your Wal-Mart price is at least better than that… PC can as Mamuang noted get through and damage peaches but IME that’s only if the bag is tight against it’s skin. I’ve had pretty good luck as long as I make sure the bag is “puffed out” and not tight against the fruit.
If the bags are durable enough I plan to wash and use them again as you did next year. I don’t expect the protection to be perfect but there is no prep time involved. My bagged Goldrush apple tends to not ripen well when using Ziploc bags.
I saw an old thread that you had tried the paper bags from Clemson. Did they ever pan out? I tried a few on peaches and plums last year but couldn’t get the technique down for getting them on very well.
Clemson Fruit bags. For those who don’t know, there is a video on how to put a bag on a peach in this link.
After several years of bagging with Clemson bags, I get a hang of it. I would give myself a B+ or A- for quality of my bagging.
As important as learning how to bag is spacing and location of fruit. Fruit that hang down are easier to bag. Spacing peaches at least 6” apart makes bagging easier, too. Good bagging, once you close the bag, there is no hole for anything including water to get in.
You need to spray pesticide and fungicide a day before. Otherwise, pests may bore hole in fruit already or your peaches will get brown rot in the bag. I have these happen to me quite a bit.
In my experience with ripe figs, that are super attractive to wasps, organza bags are 100% proof. The best they can do is to eat/lick the honey dripping outside the bags, but they completely fail to chew. They also offer excellent protection against ants and drosophila.
I have had ants bit through organza bags to get to figs. Wasps do not bother my bag figs but ripe or almost ripe pears are bigger and more attractive targets for wasps in my backyard. Last year there were swarms of them trying to get to pears but they did not bother apples (less sweet?). The large number of them stressed me out.
You don’t really need wasps for pollination, there’s plenty of other pollinators. Also, you need to catch the queens before they establish the colonies, otherwise it will not work out.
