Terumot & Ma’aserot

According to several halachic authorities (including Derech Emunah), Mitzpe Ramon lies outside the borders of the Land of Israel. If the gemar melachah (final stage of processing) is performed in an area that is unquestionably within the Land of Israel, are the grapes obligated in terumot and ma‘aserot?

I would like to plant a Jamaican cherry tree (גרגר פנמה in Hebrew). I was told that the tree might be grafted. Could this present an issue of forbidden grafts? From what I understand, the tree is sold at Marmelstein Nursery, which I saw on your list of supervised nurseries.

Rabbi, I would like to know how to proceed if one of the five grains was ground into flour before terumot and ma’aserot were separated from the grain. Is the flour still obligated in terumot and ma’aserot, or is the mitzvah no longer applicable? According to Rabbi Nachman, the blessing on flour is shehakol because its form has changed and it is no longer considered produce. Thank you.

I have a tangerine tree in my backyard for seven years now. This year the tree yielded a lot of fruit, B”H. Do I have to take ma’aser each time I pick a certain amount of tangerines?

Fruit brought into the house through the window is not subject to the obligation of separating terumah and ma’aser. I live in a private house, though, and the fruit first goes into my yard and only after that is brought through the window. Is the fruit still exempt from terumah and ma’aser in this case, too?

I grow several vegetables in my garden such as string beans, peas, and potatoes. Sometimes I take all or some of the seeds to plant the next round of crops in my garden.

1) Am I supposed to take ma’aser from the seeds before planting, or does ma’aser only apply to edible produce?

2) If there is an obligation of taking ma’aser at this point, do I need to take ma’aser from seeds I buy at a nursery?

Do I need to take ma’aserot from the mint growing in my garden that I use to make tea?

Which poskim are lenient about eating herbs grown in planters without first taking terumot and ma’aserot?

There is a guava tree in my apartment building’s shared courtyard (with 15 families). Every week I pick two to four fruits and take them home. Am I supposed to take terumot and ma’aserot from the guava with a blessing? If the tree was in a public playground, would its fruit also be subject to terumot and ma’aserot?

I grow herbs (thyme, rosemary, basil, etc.) and use them as seasoning. We actually eat them; they don’t only provide a flavor. How am I supposed to go about taking terumot and ma’aserot from them? Each time I pick a small bunch of leaves, so I would set aside less than a leaf? For example: how much am I supposed to take from the 2-3 basil leaves that I add to the spaghetti sauce?
