Not Phil.
The price of a good fruit tree should be between 8-10 dollars, like here

It is the same price at which I buy here in Europe (in Eastern European countries at half that price).
25 dollars for a Desert Gold peach tree (which is not a variety to shoot fireworks), is quite expensive.
But I know perfectly well, since almost every year I buy trees from North American nurseries, that the price of a tree is around 35 dollars.
I believe that in the case of Agromillora (breeder of the rootpac series), its delegation in the United States, is focused on the large plantations of the North American fruit states, and they are not interested in selling half a dozen rootstocks to an amateur (that is not business), but damn it makes me angry that you have made such a huge outlay of money, to obtain a handful of rootstocks.
But hey, you already have them in your house and now it’s time to multiply them.
Through mound layering system, you will obtain rootstocks for yourself, and for half a forum.
If you leave one or two of them as “mother plants”, when they are semi-adult, you will perfectly obtain 20 or 25 rootstocks from each tree annually, through the mound layering system.
Phil, good luck with your new adventure.
