An amazing reliable garden variety of plum, Plum 'Opal' is suitable for growing throughout the country. With an earlier crop than 'Victoria', 'Opal' is a dessert plum that produces a heavy crop of excellent quality, small, yellow skinned fruits with an attractive red flush through July and August. The golden flesh easily separates from its stone and has a delicious gage flavour.

Plum rootstocks: St. Julien - Semi vigorous reaching a mature height of up to 4.5m (14')

This variety is partially self-fertile. For the heaviest crops it is best grown with another variety. If you only have room for one tree then make sure that a neighbour has a tree close by that can act as a suitable pollinator.

Estimated time to cropping once planted: 2 years. Estimated time to best yields: 4 years.

Plant the plum tree in a sunny border in any well drained soil. Prior to planting, incorporate plenty of well rotted manure or garden compost into the planting hole. Fruit trees should be fastened to a stake to prevent them from rocking in windy weather. Drive the stake into the ground prior to planting. Staking after planting may result in damage to the root ball of the tree. Plant fruit trees at the same soil level as they were in their original pots and firm them into the ground. Fasten the tree to the stake using a tree tie, and water well.
In spring, while the ground is moist, apply a mulch of well rotted manure or garden compost to the base of the tree. This will help to retain moisture throughout the summer.Feed and water plum trees regularly throughout the summer, particularly during their first two years. Fruit trees do not suffer weed competition well. Keep weeds and grass clear from within a 30cm radius of base of the tree. Thin out fruits by up to 75% to reduce the weight on the branches and produce the best quality, largest plums.Pruning plum trees should be undertaken in early summer to avoid the risk of bacterial infection. Immediately after planting cut back the central stem by about a third to encourage side branches to grow from the main stem. For the following 3 years, prune only the tips of the remaining main branches by one third. Aim for about ten main branches which will form the frame of your tree, with fruiting sub branches growing off of them. From the fifth year, some sub branches can be pruned out at the union where they join the main branch, to allow new sub branches to take their place.
