In this country, the sweetgum tree is an ornamental tree for public parks and all those gardeners who have a lot of space. It works best as a solitary plant in open areas. But if it suffers from a nutrient deficiency, it becomes less attractive.
When and how should you fertilize a sweetgum tree?
Amber trees should be fertilized regularly from May to August, ideally every two weeks. Suitable fertilizers are mineral or organic, such as compost, horn shavings or manure. Avoid calcareous fertilizers and use sparingly.
nutrient-rich soil is preferred
A nutrient-rich substrate suits the taste of the sweetgum tree. Therefore, regular fertilization is one of the main aspects of care, especially when kept in containers. Without nutrients, the sweetgum tree looks old. His growth suffers as a result, as does his susceptibility to disease.
The sweetgum tree fertilizes itself
In nature, no one comes and fertilizes the sweetgum tree. Why? Because it is fertilized, among other things, by its falling leaves. But for reasons of orderliness, local gardeners in this country collect it and send it to the compost heap. If you value simplicity, leave the leaves alone.
The period – May to August
If you want to use fertilizer, you should not ignore the appropriate period of time. The sweetgum tree should not be fertilized before May. He can receive fertilizer at regular intervals until August.
Do not fertilize after September
The sweetgum tree should no longer be fertilized by mid-September at the latest. Anyone who does so runs the risk that the tree's shoots will not be able to mature properly. The result: frost damage during the winter. Frozen shoots must then be cut off in spring.
The intervals between fertilizer applications and the fertilizer quantities
Basically, the sweetgum tree is not particularly demanding when it comes to fertilizing. It is enough for him to receive fertilizer every 2 weeks. And even if you forget, it won't hurt him. For potted plants, it takes several months for a nutrient deficiency to become noticeable. It's better to dose the fertilizer sparingly!
Suitable fertilizers for outdoor and potted plants
This is what you need to consider when choosing fertilizers:
- mineral or organic – both are suitable
- Use liquid fertilizer for potted plants
- do not use calcareous fertilizers
- Do not apply strong fertilizers such as blue grain (€12.00 on Amazon) more than once a year
- well suited: compost, horn shavings, manure
- also practical: mulch layer made of bark, grass clippings, nettle or other
