Victoria is the most widely-grown fruit tree in the UK - but with good reason. It is easy to grow and produces abundant crops of attractive plums, which are good for eating fresh and unsurpassed in the kitchen.
As with all stone fruits, Victoria is best trained in a fan or palmette shape - it is not really suitable for espaliers or cordons. Ideally it should be on a south or west-facing wall or fence, but the blossom has some frost-resistance so an east-facing situation is also possible.
Victoria will usually produce a crop even on a north-facing aspect, although in this case the plums will probably be more suited for cooking than eating fresh.
Victoria is reliably self-fertile so you don't need another pollinator. It is also a good pollinator of other different plum and damson varieties.
The main problem with Victoria plum trees is a tendency to over-crop and produce too many plums, which will usually be small with a poor flavour. For best results thin the clusters of fruitlets in May / June - you may need to remove up to half of them!
