TUI FERTILIZATION IS A KEY CARE TREATMENT THAT PROVIDES THE PLANT WITH NECESSARY NUTRIENTS. SKIPPING THIS STEP WILL IN A SHORT TIME WILL CONTRIBUTE TO THE BROWNING OR YELLOWING OF THE SPRINGS AND EVEN THEIR FALLING. HOW TO FERTILIZER THUJA TO PREVENT WEAKNESS OF THE PLANT? LEARN ABOUT THE BASIC RULES AND DATES OF TUI FERTILIZATION.
This is very popular thuja, which is most often planted along the property fence. Often they are also the only barrier separating the plot from the neighboring area. However, thujas will prove themselves not only as a traditional hedge - due to their relatively low requirements and ease of care and formation, they are often used in gardens as a single decoration. The biggest advantage of thuja, apart from the ease of cultivation, are its lush and dense shoots and intense color, thanks to which it is a graceful and elegant decoration of the property. What's more, it is a year-round species, so even in winter you will be greeted in the garden with fresh and calming green bushes.
However, the fact that thuja is an all-year-round species requires maintaining the proper order and sequence of care work, mainly fertilization. Importantly, fertilizers should be adapted to the season and the natural development and needs of the plant. In the article you will find a complete guide on the proper fertilization of thuja. We will also tell you what fertilizers to choose and how to dose them.
When to fertilize thujas?
In general, thuja fertilization is conditioned by the soil's abundance of nutrients. If your plot is located in a sandy area, and the ground is light and barren, the requirements of the bushes will be much higher, and the doses of fertilizer should be higher and more frequent. In contrast to humus and fertile soils, which usually contain an incomparably greater amount of nutrients, therefore fertilization can be moderate.
AS A PRINCIPLE, THERE ARE THREE MAIN DATES FOR TUI FERTILIZATION:
spring - with the beginning of the growing season, at the turn of April and May
summer - fertilization is carried out in June
autumn - at the turn of September and October.
So, fertilization of shrubs should be carried out 2 or 3 times a year, and the division into terms is intended to help determine the type of fertilizer needed. This is a key tip, because the composition of the agent used significantly affects the condition and proper development of the plant, and also protects the bushes against winter frosts.>
What to fertilize thujas?
As mentioned above, the type of fertilizer and its composition are conditioned by the season.
For spring and summer fertilization, we recommend preparations in which nitrogen is the main ingredient. In addition to nitrogen, spring and summer fertilizers should contain a large amount of macro- and microelements in an amount corresponding to the needs of the shrub. Among the elements that play a significant role in the development of the plant, we distinguish magnesium, which prevents the yellowing and browning of shoots and the dying of twigs.
It should be emphasized that nitrogen fertilizers should be used only in spring and summer, and the last fertilization with a preparation containing this element cannot be done later than in July. The main reason is the effect of nitrogen, which stimulates plants to grow, which, given the approaching winter, could contribute to insufficient lignification of young shoots and, consequently, to freezing of the plant.
The last, autumn fertilization should be made with a preparation with a high content of phosphorus and potassium. These elements affect the strengthening of the bush before the onset of winter and strengthens their frost resistance.
What fertilizers to choose for here?
In garden shops you will find a wide range of fertilizers that will be used when fertilizing shrubs. Almost every manufacturer has in its assortment preparations that you can successfully use for thuja care.
You can choose from multi-ingredient mineral fertilizers, which, in addition to the most important nutrients, such as phosphorus, nitrogen and potassium, contain properly balanced proportions of magnesium, iron and other macro- and microelements. Properly selected ingredients affect the color and overall condition of the bushes.
Experienced gardeners recommend applying an organic fertilizer, such as compost or manure, at least once a season. We show you how to make manure in your garden. Organic fertilizers provide plants with many valuable elements, humus and valuable microorganisms, and their greatest advantage is the lack of over-fertilization. Organic fertilization is often overlooked, although, as you can see, it has a lot of significant positives that translate into improving the condition of plants and the substrate.
If you are unsure which type of fertilizer to choose, we recommend consulting a qualified garden store employee who will advise on available alternatives. A good solution is also to use fertilizers intended specifically for thujas and conifers, thanks to which the risk of making a mistake will be much lower.
Dosage of fertilizers for thujas
Mineral fertilizers are available as granules, in the form of liquid fertilizers, and even as a long-acting agent that releases nutrients into the soil for up to 3 months. Long-acting fertilizers are more expensive than traditional ones, but thanks to their prolonged action, one fertilization per season is enough.
Fertilizers in the form of granules should be scattered around the trunk of the bush, gently mixed with the ground, and then watered abundantly. Fertilizers in liquid form should be diluted in water before use. Remember to never water the bushes with concentrated fertilizer straight from the bottle, because such a strong concentration can burn the roots and lead to the death of the plant. We suggest you read our article on watering vegetables in the garden in which we discover various secrets of watering.
The doses of individual preparations should be in accordance with the manufacturer's recommendations. Do not increase the recommended proportions on your own. It is worth emphasizing that over-fertilization of thuja with mineral fertilizer is much more dangerous for the plant than its deficiency and may result in damage to the bush.
To increase the assimilation of nutrients contained in the substrate, we recommend the use of a mycorrhizal vaccine that supports the development of thujas and makes them resistant to adverse environmental conditions.
