Everything to fertilize the umbrella fir!
The umbrella fir - this exotic-looking conifer from Asia is on the red list of endangered plant species. If that's not a good reason to look after him properly, then maybe his beautiful appearance. What needs to be considered when fertilizing?
Fertilizing - no need

In any case, you should fertilize your umbrella fir when its growth has changed to the negative. Even if the needles suddenly turn yellow, fertilization makes sense. Umbrella firs basically need nutrient-rich soil for good growth.
Suitable fertilizers for the umbrella fir
A fully-fledged fertilizer should be used as the umbrella does not only need nitrogen, potassium and phosphorus. It also attaches importance to trace elements such as iron and zinc. It is also noteworthy to use lime-free fertilizers, as the umbrella fir prefers acidic soils. For example, use:
When should you fertilize?
The first fertilizer of the year should not be made before March. It is best to fertilize first in April. Then the vegetation phase of the umbrella fir starts really. At intervals of 4 to 6 weeks can be fertilized sparingly. It is important to fertilize potted plants more often than free-range plants and to water them extensively after fertilization.
Yellow and brown needles - indications of nutrient deficiency?
Anyone who sooner or later determines that the needles of his umbrella fires turn yellow or brown should question fertilization or non-fertilization. In most cases, needles that are discolored yellow to brown indicate dryness and a lack of nutrients. The brown parts are not recovering anymore. You can cut them off.
Tips
Young umbrella firs are happy about a gift of Epsom salt. The Epsom salts make them less sensitive to frost in winter.
