The same thing happens with garden plants and flowers. Usually, they need a lower concentration of fertilizer in contrast to fruit and vegetable crops. Therefore, you’ll always note that NPK numbers of fertilizers for flowers are usually lower.

However, there are other important features that can help you identify a good fertilizer for plants and flowers. In this buying guide you’ll find them all.

Types of Fertilizer

There are lots of best fertilizer for grass, plants and flowers. Some says, kind of fertilizer pollution in water. But natural fertilizer don’t make any pollution. Example, natural nitrogen fertilizer is safe for any kind of soil. Bu some new natural lawn fertilizer are not safe. So, pet safe lawn fertilizer is available in the market. That you can buy if you are a pet lover. So don’t use new lawn fertilizer unless you are confirm about that one. Because fertilizer burn lawn easily. All are not Milorganite fertilizer. Safe fertilizer meaning homemade lawn fertilizer, or straight lawn fertilizer.

In the market, more fertilizer available. Such as fall lawn fertilizer, yard fertilizer, koch fertilizer, spring lawn fertilizer, liquid fertilizer, palm tree fertilizer, bermuda grass fertilizer, scotts lawn fertilizer, lawn care fertilizer, starter fertilizer, anhydrous ammonia fertilizer, stardew valley fertilizer, and much more.

Composition

Fertilizers for plants and flowers usually have lower nitrogen concentrations than other fertilizers. Why? To understand this, it’s also important to know the effect of this essential mineral on plants.

Nitrogen plays an important role in photosynthesis. For example, when a plant receives more nitrogen, chlorophyll production is stimulated. As a result, green-leaf plants tend to show a more intense color than normal.

Nitrogen also promotes leaf growth and production. However, when the plant focuses all its energies on this process, there’s not enough energy to produce flowers. That’s the main reason why fertilizers for plants and flowers are lower in nitrogen. In simple words, the more the nitrogen, the less the flowers.

In addition, the phosphorus concentrations in this type of fertilizer can be considerably high. An example of this is the NPK number of the Scotts Super Bloom fertilizer, which appears on our top 10 list. It has a 12-55-6 formula, where phosphorus represents more than 50% concentration by weight.

The reason for these high levels of phosphorus is simple to explain. Phosphorus is a natural blooming stimulant. When its levels are high, there will be higher number of flowers with a larger size.

On the other hand, potassium, represented by the number 6 in the formula, helps to strengthen the natural defenses of the plant against pests and external agents. It also plays an important role in carbohydrate metabolism. So, it also helps plants grow taller and stronger.

NPK numbers

The NPK is the series of three numbers that represent the concentration of “nitrogen-phosphorus-potassium”. Every fertilizer on the market has its own unique NPK number. For example, “8-11-5” or “12-55-6”.

As you can see, the number in the middle, which represents phosphorus, is higher than the rest. This is the basic formula of fertilizers for plants and flowers. So, always remember this every time you go shopping for fertilizers.

In the market, you can also find balanced fertilizers, which are usually sold like “all purpose” products. The NPK of these fertilizers is usually the same number repeated 3 times. For example, “10-10-10”. Although these fertilizers can be applied to plants and flowers, it’s also true that they aren’t always effective.

For example, if the soil is naturally rich in nitrogen, applying these types of fertilizers will only increase the nitrogen concentration. As a result, the plants won’t bloom. In that case, applying pure phosphorus or a balanced mix of phosphorus and potassium will fix things.

For example, a “0-30-12” formula, where nitrogen isn’t present. These kinds of fertilizers, where any of the NPK numbers is “0” are also known as incomplete formulas.

Before applying any kind of fertilizer, it’s necessary to know the nutritional requirements of your plants and flowers. On the Internet, you can find this information specified by plant species. It would also be good to know the current composition of the soil through a soil test.

Application Mode

Fertilizers are also available in a wide variety of presentations. They can be liquid or solid in the form of powder, granules, spheres or spikes. Each variety with their own pros and cons. However, which one is the best one?

Liquid

Liquids guarantee rapid assimilation through the roots. In addition, they’re very easy to apply. You can pour them pure or dissolved with water. However, liquids have a major con. They may evaporate. They can also reach groundwater and contaminate nearby water bodies.

Powder

Powders on the other hand can be directly poured into the ground or dissolved in water and applied to plants. They’re incredibly effective and durable. In addition, a small dose is sufficient to treat a large area. However, some powders tend to burn plants and flowers.

Granules

Granules can’t be applied directly on the plant. They should be mixed with humid soil. They’re especially effective in treating mineral deficiencies in the soil. On the other hand, their main problem is the long time they take to dissolve.

Spheres

Spheres work the same way than granules. In this case, a permeable sphere filled with fertilizer powder is mixed with the soil. The amount of dissolved granules varies depending on the temperature. When the temperature is higher, there’s a greater dissolution and vice versa.

Spheres are more effective than granules, because they dissolve more easily. However, their permeable shells tend to take too long to degrade.

Spikes

Spikes are small capsules with a characteristic pointy end that makes them easy to bury in the soil. They’re also quite effective but they may take too long to dissolve. When this happens, a thin layer of white mildew grows around the spike. As a result, fungus proliferates and then attacks the plant.
