I had a plum tree which sprouted a shoot under a grass path about a metre and a half and you would not believe the amount of fruit it has got on it this year, we also chopped down the original tree and I think yours will do the same (fingers crossed). I was told mine wouldn't produce fruit but it has by the ton. Hope you have the same outcome with yours. You never know just give it a go.

It depends on what the rootstock, if any, was, Rogi. It may be a seedling plum, or it may be a variety of stone fruit selected for disease resistance and fast growth, but not fruit production. If a seedling, the fruit will be very variable, with about a 10% chance of the fruit approaching the quality of a named variety. If a named variety of rootstock, such as 'Nemagard', it will probably be small and leathery. If the leaves look like plum leaves, it is probably a seedling rootstock.

Hallo Oliveoil & Tugbrethil. Thanks for your answers. I will leave it where it is for a year or so and see what happens, it isn´t in the way at the moment, maybe I will have the luck that Oliveoil had...fingers crossed !.

On our allotment there are several yellow plum trees that Gerry says are suckers of the original tree on the allotment next door! Next door's allotment has a shed at the end of the plot with several yellow plums growing on both sides. I have no idea which tree is the original & which are the suckers but they all produce tonnes of fruit. Gerry also has another yellow one behind our shed. It was absolutely loaded down with plums until a couple of weeks ago.

So, like you said, if it isn't in the way where it is, leave it another year or two & see if it produces fruit & what the fruit is like.

You can see some of the fruit & the trees if you have a look at my blogs for July/August.
