Walnut trees generally don't require much in terms of care. They are very undemanding – especially when it comes to fertilizing. Nevertheless, we advise you to provide your beautiful garden friend with the nutrients it needs once a year. This article will tell you how best to do this!
How should you fertilize a walnut tree?
To optimally fertilize a walnut tree, you should spread ripe compost around the trunk once a year and work it into the soil. This naturally provides the tree with nutrients, improves soil quality and promotes moisture absorption.
The walnut tree – an easy-care plant
Ultimately, a walnut tree just needs an adequate location in order to thrive and bear fruit over the years (more like decades). If the tree finds sufficient nutrients in the soil, it is (almost) perfectly happy.
However, we recommend not taking any risks and fertilizing the walnut tree regularly, despite its undemanding nature. Once a year is enough.
Which fertilizer is suitable for the walnut?
Good news right away: you can easily do without fertilizer from specialist retailers. As a rule, you do not need to buy any liquid, solid or organic fertilizers for a walnut tree.
Instead, it makes sense to pamper the walnut with the necessary nutrients naturally. Choose the simplest and cheapest solution: mature compost.
Fertilize walnut trees – in three easy steps
- Wait until your walnut tree has lost its fruit.
- Place the ripe compost on the ground around the trunk of the walnut.
- Then carefully work the compost into the soil.
Natural fertilization improves the soil in two ways:
1. They optimize the soil quality in terms of nutrients.2. They loosen the soil, making it easier for it to absorb moisture.
Extra: When you should do a soil analysis
Is your walnut growing poorly? Is it perhaps not producing fruit despite being ripe? Or is the tree developing wilted leaves?
In these three cases you should carry out (or have) a soil analysis. This is how it works:
- Take a little soil from the immediate vicinity of the trunk.
- Put the sample in an airtight container.
- Take the container with soil to a nursery or laboratory.
- Let the experts there test the soil.
- See which nutrients that are important for the walnut are missing in the soil.
- Then carry out targeted fertilization.
