The most commonsymptom of improper fertilization of thuja(thuja) is their yellowing and browning. To prevent this, it is necessary to provide them with the optimal dose of nutrients on a regular basis. Seewhat to fertilize the thujas so that they grow fast, do not turn brownand keep their he alth and beautiful appearance for many years. Learndates of fertilization tujand the basic principles of using thuja fertilizers. We also advisethe best fertilizers for tui , available in our stores.
Thuja should be fertilized with special thuja fertilizers enriched with microelements
Secrets of fertilizing tuiis revealed to us by MSc. Agnieszka Lach, a graduate of the Faculty of Environmental Management and Agriculture at the University of Warmia and Mazury in Olsztyn. On a daily basis, he is professionally involved in the care and arrangement of plants in offices. He also has experience gained while working in the farm. orchard. The author of many interesting tutorial articles on gardening and an expert on the gardening forum.
When to fertilize thujas?
Thuja growing in our gardens should be fertilized 2-3 times a year. There are3 dates of tui fertilization :
- spring , i.e. from March to April, by mid-May at the latest
- summer(early June)
- autumn(September-October)
On heavy and nutrient-rich soils, we sow thuja fertilizers once in early spring , as soon as the vegetation starts.In the case oflight sandy soils, the fertilizer dose is spread over 2-3 fertilizationThis will ensure the best use of the supplied nutrients and limit their leaching from the soil during rainfall.
In spring and summer we use thuja fertilizers with a high nitrogen (N) content.Apart from nitrogen, spring and summer fertilizers should contain a set of macro- and microelements specially composed for the needs of thuja. Among them, the most important role is played by magnesium (Mg). Its deficiency causes yellowing and dying of thuj branches.
Remember!For the fertilization of thuj, choose fertilizers rich in magnesium, because the deficiency of this element is a frequent cause of yellowing and dying of thuja branches.
Fertilizers containing large amounts of nitrogen should be used by mid-July at the latest.Later supply of thuja with nitrogen causes a delay in the lignification of the twigs , and thus reduces the tree's frost resistance.
In the fall, we use nitrogen-poorfertilizers, rich in phosphorus (P) and potassium (K). These elements play a very important role in building resistance to low temperatures in plants. Fall fertilizers begin to appear in stores in the second half of July.For autumn fertilization with tujyou can successfully apply autumn fertilizers for conifers by Target or Vila.
Which fertilizer to choose for tuj?
For the fertilization of tujwe can use single-component fertilizers, such as ammonium nitrate or potassium sulphate. Their dosage, however, requires specialist knowledge and will not always allow us to provide all the ingredients needed for growth.
Therefore, multi-component fertilizers containing balanced doses of macro- and microelements necessary for the life of thuja are much more often chosen. By choosing this type of fertilizer, we will avoid one-sided over-fertilization or shortages.fertilizers intended specifically for tuiare a good choiceSuch fertilizers include, among others. Target fertilizer for thuja with micronutrients and fertilizer for conifers and thuja with bas alt flour. They contain the right composition of ingredients that prevent yellowing and browning of the twigs and accelerate the growth of thuja. Including so important for the intense color of thuja scales - magnesium and iron.
Too frequent and excessive use of mineral fertilizers can lead to soil salinity. As a result of the salinity of the soil , it is difficult to take up nutrients from the soil , which weakens the plants and increases susceptibility to diseases. Therefore, it is also worth applying organic fertilizers such as compost or manure at least once a season. Organic fertilizers have many advantages. They improve the soil structure, enrich it with easily digestible nutrients and microorganisms. A special feature of organic fertilizers is that they cannot be fertilized with plants.
If we do not have access to compost and manure from our own garden or farm, a good alternative is Florovit Pro Natura granulated compost, available in garden stores. Thuja can also be watered using Biohumus Extra for conifers, specially developed for their needs. Compared to traditional vermicelli, it is slightly more acidic, which meets the needs of most conifers and thuja.
How to dose the fertilizers?
We feed Tuje usingfertilizers in various forms. Currently, the most popular are granular and liquid fertilizers.Granulated fertilizers for tuiare slower-acting preparations. The measured amount of granules (usually 100g per tree) is spread around the trunk. Mix the fertilizer with the top layer of soil to choke its absorption into the root zone and water the plant abundantly. Shake off the fertilizer granules lying on the twigs, because in contact with moisture (dew, rain) they can cause plant burns.
Liquid fertilizers are fast-acting fertilizers. Thanks to their form, they immediately penetrate the soil and are absorbed by the roots.Thuja liquid fertilizersdilute in water, using the dose recommended by the manufacturer, which is given on the packaging. We never use concentrated fertilizer straight from the bottle. This way we can burn the roots, which will lead to the complete death of the plants.
How to improve fertilizer absorption by thujas?
In addition to fertilizer, it is also worth using a mycorrhizal vaccineThe preparation contains mycorrhizal fungi that symbiotic with the roots of thuja, making it easier for the plant to take up nutrients and water from the substrate. Thuja mycorrhiza improves plant growth and makes them resistant to environmental stresses, including drought. Thanks to the better absorption of minerals from the soil, after the application of mycorrhiza, we can also reduce the doses of fertilizers used.
