The percentage of each nutrient is clearly visible on each pack of fertilizer; for example, if the package is labeled "10-5-5", it means that the fertilizer contains 10% nitrogen (N), 5% phosphorus (P) and 5% potassium (K). Any fertilizer that supplies all three of these nutrients is called "complete".
Before every sowing it is important to add the nutrients that the garden soil needs and to control the level of PH necessary for a proper biological balance. Performing a simple test helps determine which nutrients need to be added. Many people rely on test kits sold in gardening centers but, however, it is possible to send a sample of land to an agricultural institute for a precise evaluation of the state of health.
If you do not have time to test the soil and you are not sure what it needs, you can use a balanced fertilizer such as 10-10-10, which means that it has an equal number of each main ingredient. It is also possible to buy fertilizers that contain secondary nutrients such as calcium and sulfur or trace elements such as iron and zinc.
Fertilizers are available in three forms: granular that can be worked directly into the soil with good weeding or dissolved in water; liquid that is applied during irrigation; leaf that is sprayed directly on the leaves. The plants absorb most of their nutrients from the soil, so the first job is to make sure they have supplied the right amount of fertilizer and soil and a satisfactory PH. (If the soil is too acidic or too alkaline, the plants are not able to absorb the nutrients they need). Most soils also need the addition of nitrogen that is constantly depleted.
ORGANIC FERTILIZER FOR FLOWERS
To prepare the garden it is necessary to dig well, to insert abundantly the decomposed organic fertilizer together with lime or sulfur according to the needs of the soil PH. Then place two fingers of fertilizer in order to enrich the soil and mix and distribute it evenly. When sowing annual or perennial plants, it is necessary to insert a bit of organic compound and a bit of fertilizer into each hole dug.
Organic fertilizers should be incorporated into the soil of the garden before sowing, as they release their nutrients especially with the help of bacteria present in the soil decomposing slowly and feeding the plant roots for weeks or months. Organic fertilizers also provide significant environmental benefits. In fact they tend to remain in the soil instead of polluting the air or water sources and also constitute the natural habitat for earthworms and microbes.
CHEMICAL FERTILIZER FOR FLOWERS
Chemical fertilizers are generally less expensive and fast-acting than organic ones, but they must be applied more frequently and therefore there is a risk that plants can burn. If you decide to use a chemical fertilizer you must choose the slow release fertilizer to gradually sprinkle the nutrients. Annual flowering plants must be fertilized at least every month but, when they are grown, fertilization can also take place every two months. The reduction of flowers or the yellowing of the leaves often sends the signal that the plant needs more nitrogen. Furthermore, it is essential after fertilizing a good watering because the soil is too dry and with undiluted chemical fertilizer, it can burn the roots of plants.
Finally, it should be kept in mind that too much fertilizer can seriously harm plants with flowers until they dry out or burn them completely and, at best, slow down growth by making them weak.
Fertilizer for flowers: TIPS ON FERTILIZERS FOR FLOWERS
It should be borne in mind that water should never be missing from flowering plants. If you are not sure about the type of fertilizer to be used for a given plant, you should contact a specialized center for the purchase of specific fertilizers. A properly used dose of fertilizer is usually the best way to encourage the development and growth of plants and their flowering especially if the color of the leaves and flowers is scarce. Today it is also possible to visit the numerous databases available online for clarifications and advice on fertilizers and the appropriate measures to obtain satisfactory results in one's own garden. In fact, every single plant is cataloged and thanks to this database, it can supply the specific fertilizer for the care of each individual species. All plants need to be fed and nourished and none can escape this rule. A well-fertilized soil regardless of whether it is already rich in mineral salts or organic substances that are also present in nature, require specific fertilizers. You can therefore choose between liquid products that are faster to administer to the plant but nevertheless the best and therefore, the most recommended are undoubtedly the granular ones that allow a slow release of the nutrients in the soil.
