Potential rootstocks: B9, B10, M26, M106, B118 or any other better suited rootstock.

Hi, those are all adequate rootstocks, your question really becomes what kind of planting system do you want? Tall spindle? Free standing or supported central leader? You also have to take into account scion vigor, Red Chief and Sweetango being less vigorous. B.9 and B.10 will give you a small tree and should be planted as close as 2 to 3 feet. They would not be recommended for weak growing Delicious or SweeTango. M.26 needs support, but will be a bigger tree, planted at distance of 6 to 10 feet depending on scion vigor mostly. M.106 add B.118 are much bigger trees, can be free standing, and should be planted at distance of 10 to 16 feet. M.106 does not like poorly drained soils at all. I would take a look (if you have not already) at these articles for more information and maybe help choosing your rootstock. Good luck. Jon

Dear Jon,

Yes, we are using top spindle. And will have a look at the articles you provided.
Thank you very much for your answer!

Kind regards,
