I have three plum trees, I have no idea what they are or how old they are (we have been in the house 1 1/2 years). Two are side by side and espaliered (opps probably incorrect spelling) in a netted vege garden area and another is about 5 metres away.
Last year the tree on it's own had a good crop of plums which all split as we had some heavy rain around December. One of the other trees produced two plums (wow they were nice). The other produced none.
This year there are three plums growing on the tree on it's own ....

Why are my trees not fruiting? I even tried self-pollinating between the three ... was that a wrong thing to do? The reason I did that was a neighbour said that he has been getting no plums of late either and he blames the lack of bees. I had planted some 'beneficial insect blend' under the trees in the vege garden and some borage nearby as well in order to attract bees.
Any advice/suggestions so I can eat my own plums next year?
Ta in advance,
Sue
