How should I clean grape leaves from insects for cooking? Is it possible to buy leaves that are already insect-free?

Am I allowed to pick and eat olives from my tree?

In my backyard I grow parsely, corriander, mint, and celery and I wanted to ask if there is any way for me to make them edible from a halachic perspective? If not, is it possible to turn them into a paste by grinding them, and then the principle that a partial organism is nullified in a ratio of 1:60 would apply (I understand that with strawberries you can grind them and turn them into ice cream). Thank you.

Is it true that it’s enough to soak leafy vegetables in a fruit and vegetable cleanser (like Sterili) and check a sample (organic vegetables)? In any case, why can’t we just use salt water or vinegar like we used to in the past?

I saw on your website your responsum where you permitted soaking Chasalat leaves on Shabbat in soapy water, and said that you don’t have to worry about killing insects. You didn’t relate to the prohibition of borer (like soaking vetch). Is borer an issue here?

Can I juice leafy vegetables not grown with special insect-free supervision, using a juicer for hard fruits and vegetables? The juicer grinds the flesh of the fruit/vegetable, and then separates the flesh from the juice by a centrifuge and a fine filter. The filter holes are extremely fine and rarely, if at all, does fruit or vegetable bits mix in with the juice. Note that in order to produce a little bit of juice a lot of vegetables are needed, so the cost of using supervised insect-free leafy vegetables for this purpose is very high.

I received a kit for growing garden rocket at home. I know that there are many complications related to growing leafy vegetables. What can I do so I can eat the leaves that grow? Is there some sort of pesticide that I can use? Or a net? Also, how should I check the leaves so I don’t transgress the prohibitions involved in eating insects? Thank you!
