The conifer fertilizer from Kölle's Beste is the price-performance winner in our comparison. In terms of nutrient density, it performs slightly worse than the other two recommended fertilizers, but the values are still convincing - especially since this conifer fertilizer also contains a lot of magnesium and guano (121.99€). Guano, the seabird dung, is said to increase the resistance of the plants.
Purchase Criteria
kind
Organic: Organic conifer fertilizer consists entirely of natural substances - these are of animal and/or vegetable origin. Before the raw materials in the fertilizer are available as a source of nutrients for your plant, they first have to be converted or extracted by soil organisms. Accordingly, there is no immediate effect, but a long-term effect. In addition, the soil is not contaminated with artificial substances - another advantage of the organic conifer fertilizer.
Mineral: Mineral conifer fertilizer has synthetically manufactured ingredients, but they are water soluble. This has the advantage that your plant can absorb and utilize the substances directly. The major disadvantage lies in the uncertainty as to whether it also contains raw materials that are classified as harmful to human and animal health. If you have pets, it is better not to use mineral fertilizers for conifers, but give preference to organic or high-quality organo-mineral ones.
Organic-mineral: Organic-mineral conifer fertilizer combines organic and mineral substances. It creates both an immediate and a long-term effect.
composition
In general, evergreen conifers need a lot of nutrients in order to actually be "always green". Of the "big three", i.e. nitrogen, phosphorus and potassium (NPK), they particularly need nitrogen. Phosphorus and potassium should also be included, but do not have to be large.
Conifers long for one substance very strongly: magnesium. The conifers absorb the mineral through their roots or directly through the conifers. Magensium ensures a rich, fresh green. Since it is stored and broken down in the needles, conifers in the home garden are constantly dependent on replenishment.
tips
Magnesium washes out quickly on sandy soils. And of course, adjacent plants also claim it for themselves. It is all the more important to regularly add magnesium to the conifers. You can also use Epsom salt (magnesium sulphate) from time to time as a supplement to the classic conifer fertilizer (NOT as an alternative!).
In addition to nitrogen and magnesium, the chosen conifer fertilizer should contain large amounts of iron and sulfur. Very few universal fertilizers meet this requirement, which is why we advise you to use a special fertilizer for coniferous trees.
consistency
Fluid: Liquid conifer fertilizer is commonly a concentrate that you simply dilute with the irrigation water to administer. Usually you have to apply liquid fertilizer more frequently (every one to two weeks), which means more effort compared to granulated fertilizer.
Granulated: Spread granulated conifer fertilizer on the ground around the plant and then gently work it into the soil. Although the granulate is normally used much less frequently than liquid fertilizer, you have to be particularly careful here in order to provide your plants with the best possible care.
Entity (package size/contents)
When comparing prices for the different conifer fertilizers you have shortlisted, it is important to look at the entity - the size of the pack. In this way you can quickly find out which product has the best price-performance ratio.
tips
Also consider range. Depending on how often you care for the plants with the respective conifer fertilizer and how much of the product you have to use, a smaller pack can sometimes even last longer than a larger one.
youtubefrequently asked Questions
What is conifer fertilizer?
Conifer fertilizer is a fertilizer that is specially tailored to the needs of conifers. 'Conifers' is a collective term for all evergreen conifers, including yew and fir, juniper and pine or the very popular thuja. In the home garden, these plants depend on being fertilized regularly by their gardener. Otherwise they grow weakly, become yellowish-brown instead of juicy green or die completely.
For which plants is conifer fertilizer suitable?
Conifer fertilizer is suitable, for example, for the thuja hedge, the fir, the yew and the cypress. In principle, you can use the special fertilizer for all conifers and evergreens such as boxwood, privet and cherry laurel. This type of fertilizer is also suitable for rhododendrons.
How do I use conifer fertilizer correctly?
This mainly depends on whether the conifer fertilizer is liquid or granulated. Give liquid fertilizer regularly over the irrigation water. Granulated conifer fertilizer generally only needs to be spread once or twice a year and then worked into the soil.
In general: Follow the manufacturer's instructions on the packaging!
Epsom salt or conifer fertilizer - what should I use?
It is best to use both conifer fertilizer and Epsom salt for your conifers. You should take the conifer fertilizer as a basis, because it contains all the nutrients essential for the plants. In contrast, Epsom salt (also known as magnesium sulfate) is recommended as a supplement. It contains a lot of magnesium and sulfur and can help to prevent any signs of weakness (yellowish color et cetera) right from the start. Simply sprinkle fertilizer-grade Epsom salt once or twice a year. Don't forget to refill!
What brands offer good conifer fertilizers?
There are numerous reputable brands that also offer high-quality conifer fertilizer. These include, for example, Compo, Neudorff (Azet), Dehner, Cuxin, Oscorna and Substral.
Where is the best place to buy a conifer fertilizer?
Conifer fertilizers are available in well-stocked hardware stores - such as OBI, toom or Hornbach - as well as in garden centers. Sometimes you may come across a useful conifer fertilizer at a reasonable price at the discounter (Aldi or Lidl). However, Amazon offers you the largest selection.
equipment
magnesium sulfate
Epsom salt or magnesium sulphate in fertilizer quality serves as an additional fertilizer with which you can meet the high magnesium requirements of the evergreen coniferous trees. But: Never spread more than twice a year. Because over-fertilizing with magnesium can also cause problems.
