Maintaining an avocado tree is a great way to enjoy the delicious avocados it produces over a few years – but only if it’s adequately looked after. Pruning a large avocado tree is a crucial part of this process, which can seem daunting to some. So, if you’re looking to get the most out of your avocado tree – here’s your guide on how to prune.
Background Information
Large avocado trees can reach heights of 8-10 metres; dwarf varieties are smaller, reaching a maximum height of 3 metres. Avocado trees have a broad canopy with an umbrella-like shape and grow best in warm climates; they thrive under heavy sun and steady temperatures. Pruning a large avocado tree is important to keep its size and shape, which allows air to circulate and aids in sprinkler irrigation.
What You’ll Need
Before pruning any avocado tree, it’s important to have all the necessary tools. Be sure to have pruning shears, trimming shears, and lopping shears. Lopping shears will be necessary for pruning any woody branches, while trimming shears are ideal for soft and green stems. Additionally, depending on the size of your avocado tree, a tree ladder might come in handy.
The Pruning Process
With the right equipment in hand, the avocado tree pruning begins. Start by removing any dead, dying, or diseased branches, which inturn prevents the spread of pests and diseases. Also, it’s best to remove any crossing branches to start, which can lead to splitting bark and excess shading. Finally, carefully cut any weak and damaged branches (as close to the trunk as possible) using the appropriate pruning shears.
When pruning a large avocado tree, be sure to take a step back every now and then and assess the tree as a whole. This should be done in order to recognize any structural issues or weak limbs that could put the tree at risk when a strong wind comes along – which can be common in warm, humid climates.
To prune a large avocado tree, experts recommend looking out for rough, stubby branches that detract from the tree’s aesthetic, as well as any water sprouts (vertical stems) that have sprouted near the trunk.
Kids, Branches, and Protection
When pruning a large avocado tree, take care to not push an excessive amount of growth away from the tree’s center – or ‘kidney’. When too much growth is concentrated in this area, the tree can become vulnerable. Therefore, be sure to allow a nice balance of branches that reach both in and out of the tree’s center – and always approach pruning from the outside in.
Furthermore, it’s essential to protect the tree when pruning and this means wearing protective clothing, such as gloves, a long sleeved shirt, and coveralls or pants. In addition, pruning the tree during the right season is important – the winter months are ideal as the cold weather slows down sap production.
Safety Considerations
Safety is paramount while pruning a large avocado tree and therefore, expert tree care skills are recommended. Wedging, topping, or lion’s-tailing are all dangerous methods that can lead to weakening a tree – which can make it vulnerable to any potential storms. Even if an individual believes they have the necessary skills to do so, it’s still cunning to speak to a certified arborist to ensure there are no errors that may be hazardous to the tree’s health.
When To Prune
It’s best to prune the avocado tree in the spring, or early summer just as new growth appears. That way, there’s plenty of time for any wounds to heal before winter comes around again.
Insect Control
When pruning a large avocado tree, a seven-day interval is essential between the pruning and the implementation of pest control. If insecticides are sprayed directly onto freshly pruned branches, they can suck up more than they are able to tolerate, thereby weakening the tree. Therefore, be sure to allow at least a week before applying herbicides, fungicides, and insecticides.
Tools and Maintenance
Ensure that all tools used for pruning an avocado tree are up-to-date, sharp, and well-maintained. This doesn’t only save time and energy, but also keeps the cuts clean and healthy. Furthermore, keep an eye on pests and diseases, as they can be fatal to an avocado tree, and act immediately if any problems are spotted.
Building Strength
The collection of healthy pruning techniques known as “structural pruning” should be used while pruning large avocado trees. This will ensure branches maintain the right balance of growth, therefore building up strong “muscles” and overall strength. This is done while ensuring the tree remains aesthetically pleasing by removing any weak, stubby branches.
Taking Care
In order to get the best out of a large avocado tree, it’s important to take care and spend the necessary time to prune it correctly. Doing so will maintain the tree’s aesthetic, allowing it to continue to produce delicious avocados for years to come.
