Plant fertilizers: expert tips & special fertilizers

Plants sometimes differ greatly in their requirements. We have summarized the most important information about special plant fertilizers.

Wouldn't you like to give all your darlings the perfect care in order to be rewarded with healthy growth, rich flowering and delicious fruits? Unfortunately, for many motivated gardeners, going to the hardware store or garden center often ends in being completely overwhelmed by the overflowing fertilizer shelves. Meters of shelves full of green packaging with colorful prints are not the only thing that confuses you. For a better view of the purchase of fertilizer we have summarized the information about the most important fertilizers for you.

Fertilization is a complex issue, because the right nutrient supply is determined by a number of factors. In this article, we explain to you why plants actually need fertilizer and then present the properties of the special fertilizers for vegetables, tomatoes (Solanum lycopersicum), flower, hydrangeas (Hydrangea), roses (pink), race and autumn lawn as well as from universal fertilizers in front.

Why do plants need fertilizer?

Fertilizers contain nutrients that plants, like humans, need to survive. While they produce energy themselves in the course of photosynthesis, thereby fixing carbon from the air and from it Build up cell components, they take 14 different essential nutrients from the soil solution via the roots on. Some of these are also required to build structures, some are part of enzymes, DNA or RNA - or they are simply dissolved in the cell sap or the vacuole and fulfill their function there, for example through their electrical Charge. None of the 14 essential nutrients must be missing if a plant is to live and reproduce. But you may be wondering why plants can grow in natural locations without fertilization? In nature, nutrients move in cycles; Living things die and rot, the nutrients bound in them are released and can be used by other living things. In addition, nitrogen is constantly transported from the air into the soil and nutrients are also very slowly released from the rock of the subsoil. By removing many parts of plants from gardens every year through pruning, harvesting or mowing, we are also removing nutrients from the system which we in turn need to replace. And since many plants also get bigger every year and bind nutrients firmly in their structures, fertilization is also necessary independently of this replacement. Our fertilization in the garden allows concentration of nutrients in one place and thus faster development of soil fertility.

Special plant fertilizers at a glance

When purchasing plant fertilizers, you can choose between different types. So are mineral fertilizers or organic, organo-mineral as well as organic fertilizer available. You can also choose between application in solid or liquid form and benefit from a possible long-term effect.

vegetable fertilizer

Vegetable fertilizers contain the three main nutrients nitrogen (N), phosphorus (P) and potassium (K) in roughly balanced proportions. Because there are weak, medium and heavy consumers among the vegetable plants, the dosage is individually adapted to the culture. aubergine (Solanum melongena), broccoli (Brassica oleracea var. italiana) and cauliflower (Brassica oleracea var. botrytis L.) are examples of highly consuming vegetables. beans (Phaseolus vulgaris), carrots (Daucus carota) and cucumbers (Cucumis) are mean consumers, while peas (Pisum), radish (Raphanus sativus var. sativus) and Lamb's lettuce (Valerianella) are among the weak consumers.

In addition, many cultures have an increased need for potassium, for example paprika (capsicum), Tomatoes, pumpkins (Cucurbita), cucumbers and potatoes (Solanum tuberosum). With an additional potassium fertilization, they show better growth and fruiting behavior. When it comes to fertilizing their food, many gardeners are rightly sensitive. Of course, high-quality mineral fertilizers are not necessarily contaminated with harmful substances, but also to keep your own garden fertile in the long term, it is worthwhile to use organic fertilizers such as ours Plantura organic universal fertilizer to put. This special article informs you about various vegetable fertilizer and plant manure, which you can apply to strengthen cultures.

tomato fertilizer

Because tomatoes - as mentioned above - have an increased need for potassium compared to other vegetables, special, potassium-rich tomato fertilizers are offered for them. Of course, you can also use such a fertilizer for other plants with similar needs: lettuce, potatoes, zucchini (Cucurbita pepo subsp. pepo convar. Giromontiina), strawberry (Fragaria), rhubarb (Rheum rhabarbarum) and pumpkin love and need high doses of potassium as well. Because potassium is involved in the construction of stable cell walls and regulates the water balance, it ensures stable, maximum drought-tolerant and pest-resistant plants. This is because solid, dense cell walls are also more difficult for the proboscis of sucking insects to penetrate. Here you will find all information about special tomato fertilizers. If, like us, you are striving for a biologically sustainable supply for your garden, you can find out more about the one we have developed here Plantura organic tomato fertilizer to inform.

flower fertilizer

as summer flowers are floriferous annual or perennial plants that are usually only planted or sown for one season. Because they are often colorful and intensely flowering exotic species, varieties are bred primarily for beauty and purchased plants come from an intensive greenhouse production, these summer flowers make high demands on the supply at their final location - your garden. And since many typical summer flowers do well with a similar nutrient composition, the use of a special one offers itself flower fertilizer at.

Above all, if the plant bed is redesigned every year, the floor care must not be neglected, because soil life is strongly stimulated by regularly rummaging through the soil, which leads to the loss of humus can come. So that it doesn't come to that, we have our Plantura Organic flower fertilizer developed, which promotes humus reproduction through the input of organic material.

Tip for the right humus management: Humus management refers to the treatment of soils designed to preserve or increase humus. Here you can read what the humus content of your garden soil and what you need to do to be able to use the excellent properties of humus.

hydrangea fertilizer

The attractively flowering hydrangeas are very popular in our gardens in many forms. Common to all hydrangea species their great hunger for nutrients and their preference for acidic locations. In fact, the variable - sometimes blue, sometimes pink - coloring is the most common peasant hydrangea (Hydrangea macrophylla) due to the pH value of the adjacent soil. How exactly you Dye hydrangeas blue you can read about in our special article. Within the overall high nutrient requirements, hydrangeas absorb potassium more than phosphorus. At the Fertilizing hydrangeas you should therefore make sure that you have a sufficient supply of potassium, otherwise frost damage and failure to bloom are inevitable. In addition, all hydrangea species have a high water requirement. In the best case, this is satisfied by a correspondingly water-storing subsoil. Because humus is an excellent water reservoir, the hydrangea is predestined to be supplied with an organic, humus-promoting fertilizer that is specially tailored to its needs. According to our ethical and ecological ideas, we have ours Plantura organic hydrangea fertilizer developed, the properties of which you can find out here. A special fertilizer suitable for hydrangeas is - as long as it does not actively lower the pH value of the soil - also for many other flowering shrubs such as clematis (clematis), deutcia (Deutzia) and Philadelphus (Philadelphus) or Weigelia (Weigela) suitable.

Tip: The iron deficiency that is widespread in hydrangeas is also often due to a too high pH value in the soil. If the plants' location is not sufficiently acidic, iron will be less available in the form available to the plants - and hydrangeas are less efficient at actively changing this.

rose fertilizer

A good rose fertilizer provides a slow release of nitrogen, covering the fairly high ones phosphorus and potassium requirements of the garden queen and maintains or increases the soil quality, so that the deep rooting rose can penetrate easily and look for their water in deeper layers. Such care makes it possible to form the often pompous flowers and rose hips and to withstand cold winter frosts and stinging and sucking pests as well as possible. To achieve this, the Fertilization of roses be done primarily organically, because organic fertilizers slowly release the nutrients they contain and it doesn’t come to that "mastigen", flowering lazy and disease-prone shoots, as can be the case with fast-acting nitrogen fertilization can. Added to this is the soil-fertilizing effect of the primarily organic fertilizers: through the introduction of nutrient-poor material soil life is promoted, humus is preserved or newly formed and the structure of the soil in this way loosened up. And because humus is an excellent store of water and nutrients, your rose cannot get too much of it. Our Plantura organic rose fertilizer was developed with the above aspects in mind, so that you can enjoy your roses as much as possible and with less hassle.

Tip: Exotic varieties in particular often have problems with late frosts in spring when - after the biological clock of their origin - sprout too early or their frost protection too early regress. Sufficient potassium supply is particularly important for them.

universal fertilizer

They are not specifically, but universally applicable universal fertilizer. They are characterized by a balanced ratio of nitrogen, phosphorus and potassium compounds and often also bring a range of different trace elements with them. Unfortunately, because these are not all chemically compatible with each other, at least the mineral variants never contain all trace nutrient elements. The situation is different with organic universal fertilizers, of course. Organic fertilizers always contain the trace elements necessary for plants in small but sufficient quantities. Universal fertilizers should not be spread too lightly everywhere, because some plants have such special needs that the balanced nutrient ratio is not necessarily good for them gets. But the same applies here: With organic fertilization you are more on the safe side, because this releases the nutrients contained only slowly. Acute fertilizer damage is thus effectively avoided and the simultaneous promotion of soil quality fortunately does not damage a single plant known to us. Our Plantura organic universal fertilizer is a good choice if you want to provide high-quality fertilizer for vegetable plants, berry bushes or herbs.

lawn fertilizer

Lawns in the garden are still very popular. As a permanent monoculture, it is said to have an wasting effect on the soil beneath it. Unfortunately, this is also correct in many cases, because the lawn is considered a heavy feeder and suffers from mowing that is often too intensive in summer and from freezing ground frosts in winter. by the wrong one fertilization of the lawn this problem is exacerbated. A good lawn fertilizer works for a long time and cares for the soil under the lawn, so that soil organisms can be well aerated and Provide loosening and pull dead material from the turf into the subsoil and into humus or nutrients realize. If this is not the case, the lawn will become matted, which you can do with time-consuming work scarify have to fight. The nutrient composition of a lawn fertilizer should be nitrogen-rich in order to promote a dense lawn through constant growth and new tillers from below. But also the supply of potassium should not be neglected, because this is decisive for the water balance of Plants involved - a sufficient supply of potassium saves your lawn over long dry spells summers. The requirements for soil care, which ensures a well-aerated subsoil and sufficient humus, can only be met by in primarily organic fertilisers, which is why we strictly advise against purely mineral fertilization of the lawn want. Our Plantura organic lawn fertilizer is a primarily organic lawn fertilizer that we have developed based on the points mentioned above. He is to Caring for the lawn after the winter suitable until summer.

autumn lawn fertilizer

In order to prepare a lawn for winter, an autumn lawn fertilizer must lower the supply of nitrogen and increase the supply of potassium. A lawn that is too well supplied with nitrogen in autumn is susceptible to frost and if it lacks potassium is lacking, which could be stored in the vacuole as an osmotically effective "antifreeze", all the more so more. The consequences are then frostbite of the stalks or entire plants. In the spring, a lawn that has been damaged in this way has gaps and these gaps are unfortunately usually closed by more competitive wild herbs or moss. A special, low-nitrogen and high-potassium autumn lawn fertilization will get your lawn through the winter with less damage, so that it can sprout densely again in the coming spring. Our Plantura Organic Autumn Lawn Fertilizer brings all the advantages of our Plantura organic lawn fertilizer with itself, but due to its adjusted composition it will winterizing the lawn.
