I have a hollywood plum that I purchased in 2020. I’m just about to prune it for this year, and I saw this thread. I’ll probably stick some of the cuttings into the ground to see if they grow!
For those of you who have done this with hollywood plums (@Bear_with_me , @murky), have you used the hollywood plum as a rootstock to graft other things onto?
Reading up on this forum, I saw that Adara can act as an almost universal rootstock/interstem: Adara (Puente) Plum - Fruit tree, rootstock & interstem - General Fruit Growing - Growing Fruit. It seemed like some of the discussion was that Adara is a P. Cerasifera, like Myrobalan, which is why they make such good rootstocks and interstems.
Since Hollywood is also a P. Cerasifera, could it also be used as a universal rootsock? In a year or two, could i graft peaches, euro plums, cherries, etc., onto my hollywood cuttings (or onto my original hollywood tree)?
