Q&A

 I live in Israel in an apartment with access to a tiled roof on the 7 th floor. I wish to grow for my own consumption and to share produce, both vegetables and fruit. I will be grateful with information as to how / what I must do physically to ensure all halachic tithes are taken and removed from the produce. I imagine that harvesting will take place under these 2 scenarios: Potatoes might be harvested in a single batch -or in multiple batches Other vegetables may become available gradually (possibly every few days) throughout the season. I understand that the taking and distributing Terumah and Ma’aser Rishon physically must be performed? And that after this a tenth of what remains (Ma’aser Sheni) is removed which was then biblically given to the Levites. However, I need instructions of how and what to physically do so that my planting and harvesting complies with Halacha. I’m not sure what additional information is required -but wish to advise the following: I plan to plant in pots on the roof with holes at the bottom -in the open -or in a plastic mesh enclosed frame area -or inside the apartment, in front of a sunny window (e.g., tomatoes) If a pot has holes at the bottom but stands in a small tray to catch excess water, does this affect the halachic status? I am also considering placing multiple pots in a larger tray to conserve water—does this have any halachic implications? I hope this is enough information to assist you to be able to advise what exactly must be physically done. 

If I buy a fruit tree from a nursery, what do I need to ask to ensure that the tree was grafted according to halacha?
