Kilei Ilan (grafting): scion and rootstock combinations for trees and vegetables

Laws of kilei ilan (grafting): permitted and prohibited scion and rootstock combinations for fruit trees, citrus trees, ornamental trees, and vegetables (update: Tevet 5785-January 2025).
· The kilei ilan prohibition includes grafting scions from different species onto one rootstock (multi fruit).
· The trees bolded and marked with an asterisk* are often grafted in a forbidden manner. For trees not bolded, there is no known prohibited grafting.
· The information below relates to trees produces in large nurseries. Some small planters perform non-standard grafts at times; it is difficult to predict the possible grafting pairs and the chart below should not be relied upon.
· For a list of halachically supervised nurseries, click here.
The tables below are based on an article written by Rabbi Yoel Friedemann, published also in Hilchot Ha'aretz, and available on this website, here. Changes and updates have been made to the lists. Latest update: Tevet 5785-January 2025
