How to Properly Prune Your Plum Tree: Expert Tips
How to Prune Plum Tree?
To prune a plum tree, there are three commonly used methods: bush, pyramid, and fan.
The bush method creates an open-centred tree with a clear stem of 75cm (2½ft).
The tree size depends on the rootstock used, with ‘Pixy’ reaching 3m (10ft), ‘St.
Julien A’ reaching 3.6-4.5m (13-15ft), and ‘Brompton’ and ‘Myrobalan B’ reaching 6m (20ft).
Pruning should be done in early spring, removing crossing, weak, vertical, and diseased material.
Pyramid plum trees are smaller and can be netted against birds.
‘St.
Julien A’ rootstocks are kept to 2.4m (8ft) and ‘Pixy’ rootstocks to 1.8m (6ft).
Pruning pyramid plum trees involves shortening new branches, training and tying in the central leader, and pruning side branches annually.
Fan training involves training the tree against a wall or fence with horizontal wires fixed 15cm (6in) apart.
Plum trees can also be trained as cordons.
Pruning for pyramid plums should be carried out in April to avoid silver leaf disease, with subsequent years involving shortening the central leader and removing vertical shoots at the top.

Did You Know?
1. The ancient Romans were one of the first civilizations to widely cultivate and prune plum trees, thanks to their love for plums. They even categorized and named different varieties of plums, using them for both culinary and medicinal purposes.
2. Pruning plum trees during the wrong season can make them susceptible to a fungal disease called silver leaf. To avoid this, it is best to prune plum trees in late winter or early spring when they are dormant, as it reduces the chances of infection.
3. Did you know that dwarf plum trees exist? These compact varieties are perfect for smaller gardens or even for growing in containers. They require less pruning and are easier to maintain compared to standard-sized plum trees.
4. Pruning plum trees not only improves the tree’s overall health and productivity but can also enhance the flavor of the plums. By thinning out branches and removing the excess foliage, you allow more sunlight to reach the fruit, resulting in sweeter and juicier plums.
5. Plum trees are not only valued for their delicious fruit; they also produce beautiful blossoms. Some varieties, such as the Japanese plum tree (Prunus salicina), have stunning pink or white flowers that attract pollinators like bees and butterflies, making them a picturesque addition to your garden.
Common Methods Of Pruning Plum Trees
Pruning Plum Trees: Promoting Health and Productivity
Plum trees are a beautiful addition to any garden, and knowing the proper pruning techniques can greatly benefit their overall health and productivity. Three commonly used methods of pruning plum trees include the bush, pyramid, and fan methods. Each method serves a specific purpose and can be chosen based on the desired outcome for your tree.
The bush method involves creating an open-centered tree with a clear stem of 75cm (2½ft). This method is particularly suitable for larger plum trees, as it allows for better air circulation and sunlight penetration into the tree’s center. By pruning in this manner, you effectively prevent the tree from becoming too dense, reducing the risk of disease. Additionally, the bush method also makes harvesting plums easier as the fruits become more accessible.

Size Of Plum Trees Depending On Rootstock
When determining the size of a plum tree, the rootstock is key. Different rootstocks can result in varying heights and spreads of the tree:
- ‘Pixy’ rootstocks: typically reach a height and spread of 3m (10ft)
- ‘St. Julien A’ rootstocks: can grow between 3.6-4.5m (13-15ft)
- ‘Brompton’ and ‘Myrobalan B’ rootstocks: can produce plum trees that reach a height of 6m (20ft)
Understanding the potential size of your plum tree based on the rootstock is important for planning and maintaining the tree within your garden. This knowledge will help you make informed decisions when it comes to pruning and spacing, ultimately ensuring the healthy growth of your plum tree.
Timing Of Pruning For Open-Centred Trees
Pruning plum trees is typically done in early spring to create an open-centered form. This timing allows the tree to recover from pruning wounds before the growing season begins. It is crucial to prune before buds break, as pruning afterward can cause excessive sap flow and hinder the tree’s growth.
To create an open-centered tree, it is essential to remove crossing, weak, vertical, and diseased branches. This process ensures that the tree maintains a healthy and balanced structure. By pruning in early spring and removing these unwanted branches, you provide the tree with the opportunity to grow stronger, healthier, and more fruitful in the coming season.
Key Guidelines For Pruning Plum Trees
When pruning plum trees, it is crucial to follow key guidelines to promote optimal tree health and productivity. Along with removing unwanted branches, other aspects of the tree’s structure should be taken into consideration. Here are some essential guidelines to keep in mind:
- Pruning should be done annually to maintain the tree’s shape and size.
- Avoid pruning during excessively wet or cold periods to prevent disease and tree damage.
- Make clean cuts, close to the branch collar, to promote proper healing and reduce the risk of infection.
- Always use sharp, clean tools to prevent the spread of diseases.
- Prune away any dead, damaged, or diseased wood, as these can harm the tree’s overall health.
Quote: Following these guidelines will ensure that your plum tree remains healthy and continues to thrive year after year.
- Prune annually to maintain shape and size
- Avoid pruning in wet or cold periods
- Make clean cuts near branch collar
- Use sharp, clean tools
- Remove dead, damaged, or diseased wood
Benefits And Technique For Pyramid Plum Trees
Pyramid plum trees are a variation of the bush method that offer unique advantages and are particularly useful in smaller gardens. These trees are smaller in size compared to bush trees, which makes them easier to manage and suitable for netting against birds to protect the fruits.
To maintain a pyramid plum tree, it is important to annually prune the side branches, shorten new branches, and train and tie in the central leader. This technique encourages upward growth and helps maintain the desired shape and size of the tree. When pruning pyramid plum trees, it is crucial to carry out the task in April to avoid the risk of silver leaf disease, which can infect the tree and cause significant damage.
- Advantages of pyramid plum trees:
- Easier to manage in smaller gardens
- Suitable for netting to protect fruits
“Pruning pyramid plum trees in April is crucial to avoid silver leaf disease.”
Alternatives To Bush And Pyramid Training
In situations where space is limited, training plum trees as cordons can be an excellent alternative to bush or pyramid methods. This method involves training the tree against a wall or fence with horizontal wires fixed 15cm (6in) apart. By using this technique, you can maximize the use of vertical space while maintaining the open-centered structure.
Cordon-trained plum trees are highly productive and have the added benefit of being compact, making them suitable for smaller gardens. The vertical growth promotes good air circulation and sunlight exposure, resulting in healthier trees and better fruit production.
The method you choose to prune your plum tree will depend on various factors such as available space, desired size, and garden layout. By following the appropriate pruning techniques for bush, pyramid, or cordon training, you can ensure the health and productivity of your plum tree for years to come.
Frequently Asked Questions
