Pruning Basics
Pruning is an essential part of any Japanese cherry blossom tree’s maintenance. By pruning, you can help the tree keep its shape and ensure it blooms beautifully every spring. Though pruning is generally a simple task, there are a few basic techniques that you need to know to get the most out of your tree.
The main technique for pruning a Japanese cherry blossom tree is referred to as shaping. This involves cutting off any dead or diseased branches, and removing excess growth that could cause the tree to become lopsided. It’s always best to start with the lower branches and work your way up, as this is often where the most difficult pruning occurs. Once the tree has been shaped, you can start cutting back the more vigorous shoots to encourage better flowering and more compact growth.
It is important to remember that Japanese cherry blossom trees do not survive well if over-pruned. Therefore, you should only remove a third of the branches in any one season. This will ensure that the tree has enough time to regenerate damaged wood and recover as best it can. As a general rule, it is always best to prune the tree while it is still in bloom, as this allows you to better judge which branches should be removed and retain the trees overall shape and size.
Tools and Timing
When it comes to pruning your Japanese cherry blossom tree, you need the right tools. Secateurs or pruning shears will work well for smaller branches, while a pruning saw is great for larger limbs. It is also recommended to use gloves and safety goggles when pruning in order to protect yourself from any splinters or sharp edges.
You will also need to prune your Japanese cherry blossom tree at the right time. Pruning should ideally take place in late winter, just before new growth begins. This is when the tree is dormant and there is less risk of damage. Pruning early in the season also allows the tree more time to recover and grow before the blossoming season.
Pruning in the fall or very late in the season should be avoided as this can delay or even prevent flowering. It can also make the tree more susceptible to pests and diseases. Therefore, it is vital to only prune your tree at the right time of year.
Tips and Tricks
When pruning your Japanese cherry blossom tree, there are a few tricks that you should keep in mind. Firstly, always make sure that you are cutting the branch at a 45 degree angle and in the right direction. This will help ensure that the wound is properly sealed and not susceptible to pests and diseases.
It is also important to remember to take your time and be gentle with your tree. Rushing or being too rough can damage the tree’s bark and may even lead to infections. As a result, always work slowly, carefully and gently when pruning your tree.
Lastly, never prune unhealthy or diseased branches. While it may seem like a good idea to get rid of the diseased part of the tree, it is important to remember that this will only spread the disease and make the problem worse.
Fertilising
Fertilising your Japanese cherry blossom tree is another important part of its maintenance. Fertiliser should always be applied in early spring and mid-summer in order to ensure that the tree has enough nutrients to grow and bloom properly.
It is always best to use a well-balanced fertiliser such as an NPK (Nitrogen-Phosphorus-Potassium) mix. This will ensure that your tree has the essential macronutrients required for strong, healthy growth. Additionally, you should avoid fertilisers that are too high in nitrogen as this can result in weak growth and poor flowering.
It is also important to remember that Japanese cherry blossom trees do not need to be fertilised every year. If you notice that your tree is healthy and blooming well, then you can wait a few years before applying fertiliser again.
Watering
Watering is also an important part of maintaining your Japanese cherry blossom tree. The tree should be watered well in the spring and summer months, and the soil should be kept moist but not saturated. In addition, the tree should be watered during dry months and during long periods of drought.
It is also important to note that Japanese cherry blossom trees do not need to be watered every day. If the tree is healthy and blooming well, then it can get by with only a few waterings a month. Additionally, it is important to avoid over-watering your tree as this can lead to root rot which could prove fatal.
Pest Control
Pest control is also an important part of maintaining a healthy Japanese cherry blossom tree. Common pests such as aphids, mites, and whiteflies can cause damage to the tree and should be dealt with promptly. Several natural remedies, such as horticultural oils and insecticidal soaps, can be used to treat pest infestations.
It is also important to keep an eye on the tree throughout the year and check for any signs of infestation. If any pests are spotted, it is important to act quickly before they have a chance to spread and cause serious damage.
Winter Protection
Finally, Japanese cherry blossom trees are more susceptible to cold temperatures than other ornamental trees, and therefore need to be protected in the winter months. In order to protect the tree, it is recommended to mulch the root zone with a thick layer of compost.
This should be done in early autumn and should be done after any necessary pruning has been completed. It is also important to ensure that the mulch is kept clear of any stems or branches as this will provide insulation for the tree’s roots.
Furthermore, you may wish to wrap the tree in horticultural fleece in order to provide extra protection during particularly cold spells or frosty nights. Additionally, it is recommended to water the tree more often in the winter months in order to keep the roots hydrated and healthy.
