Learning how to prune Japanese plum tree is important to ensure its health and productivity. However, a few effective steps will make the task simple. Pruning can help increase fruit production by removing weak, damaged, or diseased branches.

This guide consists of simple steps to help you prune Japanese and even European plums. 

How To Properly Prune a Japanese Plum Tree?

To properly prune a Japanese plum tree all you need is to apply the correct techniques. First, you need to choose the right time, remove dead or damaged branches, thin out overcrowded branches, shape the tree, and finally clean up.

Pruning your Japanese plum tree properly won’t just ensure that it develops properly and grows strong, but that it produces tasty and healthy fruits. These fruits can have reddish or yellow flesh that’s aromatic and juicy. It’s no wonder that samurai considered these fruits to be a good remedy for fatigue. Read on to see how to properly shape your plum tree.

1. Choose the Right Time

Choosing the right time to prune a Japanese or European plum tree is critical to ensure the tree’s health and productivity. The best time to prune a Japanese plum tree is during its dormant season, which is usually in early spring or late winter before the new growth begins. Pruning during the dormant season allows for better visibility of the tree’s structure, making it easier to identify and remove any dead, damaged, or diseased branches.

During the dormant season, these fruit trees are less susceptible to damage and stress, and the wounds can heal more quickly. On the other hand, it’s important to avoid pruning during the fall or early winter, as this can stimulate fresh growth that may not have time to harden off before the cold weather sets in.

However, there are exceptions to the universal rule, and some plum trees may require pruning at other times of the year. For example, if a branch is damaged or diseased, it should be removed immediately, regardless of the time of year. This is especially true when pruning old plum trees.

It’s essential to research the specific needs of your plum tree to determine the best time to prune and consider some important factors, including the tree’s age, size, and the time of year that it typically produces fruit. You can help ensure a healthy and productive Japanese plum for many years by choosing the right time to prune and following proper techniques.

2. Remove Dead or Damaged Branches

Removing dead or damaged branches is critical in pruning Japanese plums for tree care and promoting healthy growth and fruit production. Dead or damaged branches can reduce the tree’s productivity and put it at risk for pests and diseases.

Dead or diseased branches can attract pests and diseases that can spread throughout the tree and damage healthy branches, and by removing these branches, you can help prevent the transmission of disease and protect the tree’s overall health.

Moreover, dead or damaged branches can loosen the tree’s structure and make it less resistant to damage from wind, snow, or other weather events. Removing these branches can help improve the tree’s overall structure and reduce the risk of future damage.

These branches can also divert the tree’s energy from thriving growth and fruit production. Their removal can help stimulate the tree to produce new growth, increase fruits, improve its appearance, and make it more aesthetically pleasing.

When removing dead or damaged branches, it’s essential to use clean, sharp pruning tools to make clean cuts that promote healing, and be sure to cut the branch at the base where it meets the trunk or a larger branch. Make sure to avoid tearing or splintering the bark.

You might be wondering, “How to prune a young Japanese plum tree?” To prune a young Japanese plum tree, remove damaged or diseased branches, select 3-5 well-spaced branches for a central leader, remove any shoots from the base or below the graft union, and trim back remaining branches by about one-third of their length.

3. Thin Out Overcrowded Branches

Thinning out overcrowded branches and fruit thinning is a crucial step in pruning plum trees to promote healthy tree growth, increase fruits, and maintain the tree’s overall shape and structure, as overcrowded branches can block sunlight, lower air circulation, and lead to disease and pest problems.

Overcrowded branches can block sunlight from reaching the tree’s inner branches and fruit, reducing their growth and quality and thinning them out, promoting better light penetration and improving the fruit’s overall quality. Overcrowded branches can also limit air circulation, leading to moisture buildup and the growth of fungi and bacteria.

Thinning these out can increase air circulation and lower the risk of disease and pest problems. Overcrowded branches can also stress the tree’s structure, lead to breakage or damage from wind, snow, or other weather events, and distort the tree’s shape and structure, making it less aesthetically pleasing and more difficult to manage.

By thinning out overcrowded branches, you can help prevent breakage and damage to the tree while maintaining its shape and structure and making it easier to manage.

When learning how to prune a plum tree, it’s essential to know that you need to remove branches that are crossing, rubbing, or growing in the wrong direction, so you need to start by removing the weakest or least productive branches, making sure to maintain the tree’s overall shape and structure.

4. Shape the Tree

Shaping a Japanese plum is important to maintain the tree’s overall appearance and structure, which involves cutting branches growing in the wrong direction or disrupting the tree’s overall shape. Shaping the tree can enhance its appearance, promote healthy growth, reduce the risk of damage, and control its size.

It’s also important to clearly understand the desired shape and structure before starting the shaping process. Hence, you need to use clean, sharp pruning tools to make clean cuts that won’t get infected and that will be able to heal faster, avoid splintering the bark, and remove any stubs or jagged edges that can make it difficult for the tree to heal.

How to prune plum tree during summer? Start by choosing the right time, ideally, when the young shoots have finished growing. Cut new branches at a height of eight inches above buds that point outward or downward. Train and bind the main figure to the stake.

5. Clean Up

After pruning a plum tree, it’s important to clean up the area around it to promote a healthy environment, reduce the risk of injury, maintain a neat appearance, and prepare for the next pruning session. Removing the pruning debris, including cut branches, twigs, and leaves, is necessary to prevent disease and pest problems from developing.

You must collect the debris with a rake or broom and dispose of them in a compost pile or yard waste bin while keeping in mind to dispose of diseased or pest-infested branches separately and not in the compost pile. Overall, cleaning up after pruning is important in maintaining a healthy and tidy garden or orchard.

Is pruning plum trees in California done differently from other states? Not necessarily, but pruning might be done earlier due to the warmer weather. Also, consider the tree’s water needs, and avoid pruning during periods of drought or extreme heat.

Conclusion

In conclusion, pruning a Japanese plum tree is a vital practice that can help improve the tree’s overall health and fruit production, and by following the appropriate techniques and timing, gardeners and farmers can control the tree’s shape and size and keep it in good condition. Here’s a summary of what you just read:

• The best time to prune a Japanese plum tree is during its dormant season, usually in early spring or late winter before fresh growth appears.
• Start by removing dead or damaged branches with clean, sharp pruning shears or loppers. Cut the branch at the base where it meets the trunk or a larger branch.
• Remove any branches growing too close together or crossing over each other, as they can rub against each other and cause damage.
• Thin out the tree by removing some of the smaller, weaker branches to allow more sunlight and air to reach the inner branches.
• Shape the tree by cutting back the branches to control its height and width. Make cuts at a 45-degree angle above a healthy bud or branch. Leave some space between the bud and the cut to prevent damage.
