When fertilizing the Thuja emerald: less is more
Thuja emerald fertilize properly
Thuja emerald is a relatively undemanding tree of life, which is maintained as a hedge or even better as a solitary in the garden. Although it needs sufficient nutrients, an over-fertilization is absolutely to be avoided. How to fertilize Thuja emerald right.
Thuja emerald fertilize - beware of over-fertilization
When fertilizing Thuja emerald, you can quickly do too much of a good thing. This is especially true if you rely on mineral fertilizer. These fertilizers quickly overfertilize.
It is better to use organic fertilizer.
Immediately after planting the Thuja emerald you only have to fertilize if you have set rootless Thujen. Bale goods are sufficiently supplied with nutrients for the first year.
Suitable fertilizer for Thuja emerald
Suitable fertilizers for the tree of life are:
The best time to fertilize
The first fertilization of Thuja emerald occurs in spring. When using slow-release fertilizers, a single dose is sufficient.
With short-term fertilizers such as blue corn, you may fertilize again until the end of July. Fertilization no longer makes sense later in the year, as the nutrient-induced renewal does not harden before winter.
If compost or horn shavings are used as fertilizer, over-fertilization is not possible. These materials slowly release the nutrients.
Take care when using mineral fertilizers
When fertilizing with mineral fertilizers, you must strictly adhere to the instructions on the packaging. Thuja emerald as a single tree needs less fertilizer than if you cultivate the tree of life in the hedge.
Avoid getting the mineral fertilizer directly in contact with the needles, trunk or roots, otherwise it will cause burns. The affected shoots then turn brown and curl up.
When does fertilizing with Epsom salt make sense?
Regular fertilization with Epsom salt is often recommended. This fertilizer is only useful if the Thuja emerald suffers from a lack of magnesium. It manifests itself through bright, yellow needles.
Before you administer Epsom salt, have the soil examined in the laboratory. So you can be sure that the needle stains were actually caused by a magnesium deficiency and not by fungal diseases or pests.
Fertilize with a mulch cover
It has proven particularly useful to protect Thuja emerald in the hedge or as a solitary with a mulch cover.
The mulch material releases nutrients during decomposition and at the same time ensures a sufficiently moist soil climate.
Tips
If the needles of the Thuja emerald turn black, it is due to a lack of manganese. It results from compacted soil that is too moist. By adding lime, the substrate can be improved so that the tree of life can better absorb the manganese from the earth again.
