I'm in NJ and therefore way behind you guys season-wise. My son wanted a 'Fruit Salad' grafted tree (we already have a multi-apple) so I went searching. My normal choice, Bay Laurel Nurseries, was out of stock for the year on their Dave Wilson trees, so I turned to Peaceful Valley/GrowOrganic.com.
I purchased a 3-1 cold hardy fruit salad for $51 including discounted shipping. It was 'the last one they had' and they couldn't hold it until it was warmer in NJ. It sat in my basement for 2 months while we battled freezing weather.
In the interim, Home Depot has their version of fruit salad trees on display - the Santa Rosa plums on their trees, without exception, look like mistakes. They are tiny little twigs usually growing right against a stem (oh, and more expensive.
Now that I've bored you with the story, it's time to unbury the headline. The tree I received is gorgeous. It is, by far, the best multi-graft tree I've ever been shipped. It turns out to be, not a 3-1, but a 5-1.
On Lovell peach root stock, I have:
Late Santa Rosa Plum
Blenheim (Royal) Plum
Gold Dust Peach
July (Kim) Elberta Peach
Independence Nectarine.
Each of the grafts seems well placed and, after sitting in wet saw dust and dirt in my basement, it still seems full of life. I wasn't crazy about the roots it shipped with, but I'm hopeful.
Here's a picture of the newbie. Hopefully it will leaf out shortly.
