Grafting

I accidentally bought a pear tree grafted onto quince. What now?

Rabbi Moshe Bloom
I bought very expensive organic trees and the non-Jew there (we live in chutz la'aretz, BTW) said they are all rooted on the same fruit rootstock – min bemino.

Now I already planted almost all trees except for one plum tree and two pear trees.

To be sure I asked again via e-mail because I felt something is wrong. And she replied that apple is rooted on MM106, Cherry is rooted on Colt and I guess those two are ok, right?

 But pear is rooted on quince (!!!)... and plum is said to be St. Juliens A which I searched for and it should also be from plum tree, but I could not find it on the list here on the website, can you verify this rootstock to be ok b"H? I did not plant the pear trees yet... can I somehow save them (cutting off the rootstocks?) or do I have to throw them away? Thank you!

Grafed by a non-Jew, planted and cared for by a Jew

Dr. Mordechai Shomron, agronomist

Hello, I am looking for information on the permissibility of the below scion/rootstock combinations for planting/maintaining outside of Israel:

  1. Southern King Pear (scion) / Callery Pear (rootstock)
  2. Sharanui Mandarin (scion) / Trifoliate Orange (roostock)
  3. Owari Satsuma (scion) / Trifoliate Orange (roostock)
  4. Miho Satsuma (scion) / Trifoliate Orange (rootstock)

    If any of these are an issue, I would like also a directive on how to treat them. I am a home gardener and planted all of these myself from 3-gallon nursery pots. I did not do the grafting. This is when I mistakenly thought that the only issue on plants that are safek mino (which I assume at least the citrus are) is the grafting, not the transferring from the nursery pot to the ground itself. Do any of these need to be uprooted or can they be maintained? Again, they were all grafted by a non-Jew but planted and are maintained by a Jew outside of Israel.

Planting grafted vegetables

Rabbi Moshe Bloom

If I want to plant seeds or roots from a vegetable I bought, do I need to worry it was grown from grafting? Such as cucumber, pepper, potato, lettuce.

Buying fruit trees in the US when the rootstock-scion pair is unknown

Rabbi Moshe Bloom

Hi, I was hoping you could help me. Any of the box stores and vendors that sell fruit trees in the United States do not list their rootstock. My understanding is that at times they can use various different rootstocks that are often not the original min. How concerned do I have to be about this when purchasing these trees?

Questions to ask to ensure my tree is grafted in a kosher way

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?

Transplanting grafted trees

Rabbi Moshe Bloom

I have citrus trees in my yard. According to the list on your website, they have a questionable status vis-à-vis kilei ilan. For this reason, grafting and planting should be performed by a non-Jew, but Jews may care for the tree both actively and passively.

1. If a Jew was involved in either grafting or planting the tree (or both)—must the tree be uprooted bedi'avad?

2. Some trees are in planters and we need to plant them in the ground. Is transplanting permitted by a Jew, or is a non-Jew's services needed for this action? That is, is transplanting considered halachically a new planting, requiring a non-Jew, or is it simply moving the tree to a larger area, considered actively sustaining the tree—an action permitted to Jews.

3. In continuation to the previous question: what happens if the transplant is performed in a way that does not necessitate a new orlah count (it is transplanted in a clod of soil large enough to sustain the tree for two weeks; the planted had a large enough hole and was attached to the ground; the planted was detached from the ground for less than 24 hours). In this case, would the transplant be permitted by a Jew, or would a non-Jew need to perform it?

Using an aloe vera leaf to facilitate shoots taking root

Rabbi David Eigner | Emunat Itecha 125, Tishrei 5780 September 2019

Recently, farmers have begun inserting shoots into aloe vera leafs for moisture and protection against fungus. Is this considered prohibited grafting?

Can one say birkat ha’ilanot on trees grafted in a forbidden fashion?

Grafting: Where is there a list of all the kosher combinations? (1)

Rabbi Yehuda HaLevy Amichay

Is it permissible to plant a tree from a lemon tree scion grafted onto a hushhash (sour orange) rootstock? Is there a comprehensive list of all the permissible grafting combinations? Are there any nurseries that follow halacha?
