Bringing fruit into the house through the window

Rabbi Yoel Friedemann

Fruit brought into the house through the window is not subject to the obligation of separating teruma 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 teruma and ma’aser in this case, too?

Taking teruma and ma’aser when picking a few fruits at a time

Rabbi Yehuda HaLevy Amichay

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?

Determining the ma’aser year for fruit that blooms early

Rabbi Yoel Friedemann

Loquat and almond trees bloom early, some before Tu BiShevat, and some afterwards. How do I take teruma and ma’aser  from these fruit?

The orlah year calculation

Dr. Mordechai Shomron, agronomist

Two months ago we bought a dwarf lemon tree that says on it “from 2013.” We planted the tree together with the clod of earth that it came with, which only fell off a little bit. Do we have to start the orlah year count again? If so, can we uproot it and replant it, and in which way can we use its fruit without waiting?

Grafting several types of citrus fruit onto one tree

Rabbi Ehud Ahituv

Is it possible to grow insect-free vegetables at home?

Rabbis of Torah VeHa’aretz Institute

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!

Juicers and regular leafy vegetables

Rabbi Yehuda HaLevy Amichay

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.

Kila’im in Vegetables

Agronomist Mordechai Shomron

Is a drip irrigation pipe considered a barrier when growing different types of vegetables on either side of the drip pipe? When it comes to seed starters do these pose a kila’im problem?
