The best starting point for a correct and successful fertilising of your Christmas trees is a complete overview of the soil type(s) in your Christmas tree field.
The only way to achieve this is by getting a soil analysis done.
When getting a soil analysis done it is important that you take samples from different spots in the field and mix them together in a bucket before you send them to the laboratory.
If the soil in your field has a very low pH value, you can normally remedy the problem with liming and subsequent mulching.
If the soil on the other hand shows to have a very high pH value there is unfortunately nothing you can do to remedy the problem.
The recommended pH values are as follows:
- Pine: 4,5-5,5
- Fir: 5,0-6,0
You should have a soil analysis done every second year to be sure that you are always updated on the specific conditions in your field.
Remember to divide your fertilising into two:
The first time from mid April to mid June and the second time from mid June to mid July.
