Victoria Plum and a Green Gage
Our Czar, Marjories Seedling and Golden Gage plum trees are maiden trees perfect for training against a south facing wall. They are grown on a moderately vigorous root stock which, with regular pruning and training will cover your wall in fruit. These varieties are self-fertile.
To give you an idea of what size they are supplied as, I have attached a photo of an apple tree delivered to the Kitchen Garden around a month ago. It is 5 foot tall in its pot and the main stem has been pruned at approximately 4 feet.
You will need to provide the tree with a strong system of training wires such as the GrippleTensioner System, and tie in the side shoots as they develop. They will need pruning each year in Late Spring/ Early Summer.
In order to train the trees you need to prune as per these RHS guidelines:
During the first summer, prune in the third week of July when the young shoots have finished growing. Shorten new branches to 20cm (8in), cutting above a downward or outward-pointing bud. Also cut side branches back to a bud at 15cm (6in). Train and tie in the central leader to the stake
In subsequent years during April, shorten the central leader by two-thirds. Repeat annually until the tree has reached 2.4m (8ft), after which, shorten the central leader to 2.5cm (1in) or less each May, to keep the tree at the same height
Vertical shoots at the top competing with the central leader should be removed in late June.
I hope this is helpful for you. Please let me know if I can be of any further assistance.
