SLN claims to be very organic, no fertilizer, mulch, etc. Not sure if the original owners was like that.
Ill have to check their catalog at my office tomorrow. Somewhere they said they're all Siberian crab for this year. Or maybe starting with this years rootstock they use.
They have great rootstock if your looking to graft your own. $4 each for Siberian crab. shipping was $25 to my house in NY. Last year bought a lot of trees. Think 11 or 12. Mostly crabapples on Siberian stock. Only exception was the Minnesota cider apple forgot the number. All grew well at camp. Despite not being able to water them much and the soil up there.
Think all my Siberian grafts took last year. M111's I got from another place weren't so hot looking and some failed. Anty was a hit / miss last year.
Hard to tell for sure at camp, but several rootstocks are doing well. Siberian dolgo ranetka antonovka. Trying more B118 and P18 up there.
