Title: single scionwood on multiple rootstocks
Post by: lavender87 on July 17, 2019, 08:42:41 AM

  Have anyone tried multiple rootstocks for single scionwood? I have the harvey lemon about 2 years old on sour orange rootstock, and I am thinking of grafting (adding) several smaller trifoliate rootstocks to the same tree.

  What will happen? Will it increase growing speed, increase cold tolerance or become more susceptible to diseases?

I was looking at my 2 Arctic Frost and was wonder why it had a graft joint about 1ft up and then another joint a little further up. I was actually wondering if that was why they were doing so bad. They were still in the house on the sun porch so I finally dragged them outside to see if that would help. I wanted to put them in the ground this year to test there hardiness but they looked anemic. I did plant one yesterday, since I had 2 of them. I bought these a few years ago and due to illness they stayed inside. They are plants from Garden Debut.

Citrus tree on 2 roots of different varieties. I have a problem with chlorosis in my garden when using trifoliates as a rootstock. The second inoculation of the rootstock, the pomelo was rescued from chlorosis and enhanced the nutrition of the tree.

 Based on your description, I think that tree has an intermediate stock of the thrid cultivar. Many famrers in my countries do so for mangos. It serves as a buffer to help increasing the compatibility of the scionwood and rootstock.

Sounds like intermddiate graft. Done to facilitate compatibility in most cases
