Do I need to fertilise my trees?
Posted on: November 6th, 2018
To the novice gardener, knowing what should and shouldn’t be done to keep your trees, shrubs and plants thriving can sometimes feel a little overwhelming. A lot of people will focus on their flowering plants, assuming that trees can take care of themselves.
However, although trees tend to be far hardier than annuals and perennials, they do still need your attention – and the right fertiliser – to ensure that they are able to survive attacks from pests or disease, particularly if they have been recently planted.
Sadly there isn’t a ‘one rule suits all’ approach when it comes to fertilising trees – they all require different combinations and quantities of nutrients and care. How much you may need to help will depend on your garden’s soil. If your soil provides the key nutrients your trees require, they will be able to flourish with barely any human intervention. However, if your soil is nutrient deficient and your chosen tree is foreign to the environment, it will need additional nutrients so that it has the best chance of surviving and thriving over the years.
Because of this, it is advisable that you do your research before planting any new trees – if a species is suitable for the area and soil type, it is far less likely to cause you problems down the line.
What type of fertiliser?
Trees and shrubs require macronutrients and micronutrients in varying proportions. These include:
Fertilisers contain these nutrients but each type of fertiliser will have varying proportions, so it is important to determine just what combination and amount your tree needs before you purchase any products. If you were to apply the wrong fertiliser, it could have terrible consequences for your tree’s health. Therefore it is recommended that you speak to the professionals – a simple soil test should provide you with all the information you need.
You may also want to look into other benefits certain brands of fertiliser contain. For example, some quickly release nutrients into the soil to optimise tree growth; others release them slowly so that your tree can absorb them over an extended period of time.
What else do I need to do?
Please note that although fertilisers are incredibly important when it comes to providing trees with essential nutrients and a healthy growing environment, you will still need to remember to regularly care for your trees with adequate water and pruning.
If you are concerned that you don’t have the time or knowledge to maintain your trees’ health, why not get in touch with a local tree surgeon? They can assess the health and needs of your trees and include the right type of fertiliser as part of their tree care plan.
