When to do: Spring
While fertiliser isn’t essential, you are likely to see increased benefits if you undertake a nutrition regime – how often you do, is up to you, however it’s recommended that you conduct this each spring. If you plan on producing fruit from your tree, then a liquid fertiliser should be used as this will keep the soil moist – something which is essential for olive production.
Using an organic fertiliser will contain components such as manure and compost, which take a longer to decompose – providing your olive tree with benefits over a sustained period of time. Using a natural fertiliser will give your olive tree nutrients which it needs to survive, such as copper, zinc, calcium, magnesium and managenese. When using organic fertiliser, you should carry this out every other year to achieve maximum benefits.
Fertiliser should be applied to the ground but not in a position too close to the trunk. Once you have applied your fertiliser, you should water thoroughly to aid absorption of the nutrients. Avoid fertilising during winter months, as this is when your tree does the least growing so you won’t see any benefits.
Using a chemical solution, will address any immediate issues that your olive tree is facing, while an organic fertiliser will provide longer term benefits for overall tree health.
