Types of fertilizers for coniferous plants and how to feed them, possible mistakes

Coniferous trees do not shed leaves, so they do not require many nutrients to synthesize cellular material. Despite the not very rapid growth, such crops still need fertilizing. However, it is important to select the right amount of fertilizer for coniferous plants so as not to overfeed them. The choice of drug composition is of no small importance.


How does the nutrition of conifers differ from ordinary trees?

When choosing fertilizers for pine, spruce or other coniferous crops, it is worth considering a number of features.The composition of the drug differs from those used for fruit trees, vegetables or berry bushes. Conifers do not require as much nitrogen as deciduous crops. Therefore, combined preparations based on nitrogen, phosphorus and potassium cannot be used.

Coniferous plants need potassium and magnesium. They also need a small amount of phosphorus. This is due to the crops’ need for chlorophyll. It is always present in modified leaves. Crops obtain this substance through photosynthesis. In this case, the root system is given a secondary function.

Photosynthesis depends on the magnesium content in the soil. This substance is present in chlorophyll, a large amount of which is found in needles. Its volume remains at the same level throughout the year. Essentially, magnesium is required in minimal quantities for the development of new branches located on the upper parts of trees.

At the same time, coniferous plants do not require large amounts of fertilizer. This is due to the following factors:

  1. Evergreen crops do not shed their leaves. Therefore, they do not require building material for spring restoration.
  2. Conifers do not bear fruit. Therefore, they do not need many useful elements.
  3. They are able to absorb the nitrogen that plants need from the air.

The dangers of nitrogen for evergreen species

An increased amount of nitrogen in the soil leads to the appearance of new branches, which may not always grow back by the time winter arrives. As a result, they die off during the cold season. Those shoots that survived the winter become very sick in spring and summer. This also negatively affects the development of conifers.

Expert:
The formation of sprouts in such conditions and the further struggle for their survival require a lot of effort.Therefore, it is better to feed plants with minerals, compost and vermicompost.

At the time of planting and for the purpose of mulching, it is permissible to use leaf humus or peat. Complex compost is also an excellent option. This will help provide the crops with the ideal amount of nitrogen, potassium and phosphorus.

What and how to fertilize trees?

Today, there are quite a few effective products that can be used to fertilize coniferous crops.

Mineral fertilizers

Coniferous plants prefer magnesium among minerals. It is similar in structure to chlorophyll and is required for photosynthesis. It is best to use dolomite flour as a top dressing. For 1 tree you need to take 0.5-1 kilogram of this substance.

Many conifers grow in acidic soil, which contains little free calcium. This substance is required by plants in early spring - during the growth of young shoots. At this stage, it is worth using fertilizers that contain some calcium in an easily digestible form. Coniferous plants require sulfur and iron. These elements are present in combined fertilizers. These include Pocon, “Fertika Spring”.

When purchasing fertilizer, it is important to analyze its composition. The combined products must contain a sufficient amount of microelements. If there is a deficiency of important components, there is a risk of developing chlorosis. In this case, the needles acquire a white or brown color.

In autumn, plants need superphosphates. In dry form, these fertilizers need to be scattered around the perimeter of the site and watered the beds. You can also add fertilizer when digging up the area and moisten the soil. Phosphorus is converted during the winter. With the arrival of spring it will become accessible to the roots.

Organic

Conifers require the following types of organic compounds:

  • vermicompost;
  • rotted compost.

Organic fertilizers must be placed around the trunk and carefully mixed with the top layer of soil. They need to be applied in the spring. The main value of such products is considered to be the content of potassium and microelements.

Special Additives

In spring and summer, evergreen crops can be fed with balanced formulations. The most effective means include:

  1. “Needles” - can be used for short plants in the spring. To do this, you need to mix 20 grams of the drug with 20 liters of water. It is necessary to apply the composition 3-4 times with an interval of 2 weeks.
  2. “Fertile Universal” – the drug activates the development of shoots. When planting 1 crop, 100-200 grams of the substance will be required. When applying the composition during the growing season, you need to use a solution. To do this, you need to mix 30 grams of the substance with 10 liters of water.
  3. "Fertika Lux" - the drug does not contain nitrogen or magnesium. It is recommended to use it once every 5 years. To prepare the solution, you need to mix 20 grams of the product with 10 liters of water.
  4. "Aquarin" - helps maintain the beauty of evergreens and strengthens their immunity. The composition should be applied 5 times during spring and summer. The last time it is applied is in early autumn. To make a solution, you need to mix 20 grams of the substance with 10 liters of water.

Possible mistakes

Common mistakes that gardeners make when feeding conifers include the following:

  • the use of fertilizers intended for fruit trees or berry bushes;
  • use of excessive amounts of fertilizers;
  • use of nitrogen fertilizers.

Coniferous plants do not require large amounts of fertilizer.In order for plants to develop normally and not get sick, it is important to choose the right composition of the fertilizer and follow the instructions for its use.
