    Yes, If the variety requires a pollinator, space must be given for at least two trees. Growing a multi-grafted tree enables a homeowner to grow a variety of fruits in the space of one tree.

    This is usually due to an aphid infection. Ants farm aphids as "pets" so this is usually an indication that there is an aphid issue that needs to be controlled. This article will help: https://www.gardeningknowhow.com/plant-problems/pests/insects/homemade-aphid-control.htm

    I would imagine a soil sample would reveal highly acidic soil, as peat will bring the pH way down. This will make phosphorus and potassium unavailable to the tree, which will prevent proper fruit formation.

    I would recommend adding dolomitic lime, and a good amount of compost to the area. This will help balance out the pH, along with give the plant a little help in replenishing nutrients. By next year, you should see better crop production.

    Your Victoria plum tree is in flowering group 3. It is self-fertile and does not need a pollination partner, but fruiting will usually be improved if there is a compatible partner of a different variety nearby. The following varieties should pollinate this plum tree.
    (European plums, gages, damsons, cherry plums, mirabelles, bullaces will usually cross-pollinate if their flowering times overlap.

    Without photos I can only take guesses, and those guesses would be some type of insect. If there are brown spots, black spots, or other symptoms, then it will be easier to diagnose.

    If pesticides don't work, then it could be fungal, in which case, you need a fungicide.

    I would recommend getting with your local extension service to test your soil, and they will be able to tell you exactly what is wrong. You will have to bring them samples, photos, or anything else they ask for but they will get to the root of your issue.
