There are more sensitive plants that suffer more from changes in their environment. Also species that in the flowering season must be treated with great care because they do not like their conditions to be affected, even though at the same time they need a soil rich in nutrients.
In these cases, the best alternative to keep the needs of the plant covered without altering its habitat is to resort to solid fertilizers, that is , slow-release fertilizers that offer the necessary nutrients, although in balanced doses .
What are they for
The first thing to know is that there is no fertilizer but there are different types according to the different species. The slow-release ones are widely used for ornamental species because this type of plant needs nutrients over time and not all at once.
Unlike traditional or fast-release fertilizers, which offer nutrients suddenly when applied, slow-release fertilizers spread nutrients over time . This happens because they are applied only once but then continue to release nutrients into the soil.
That is why they are also recommended for flowering because if the quick-release ones benefit the flowers that are already on the plant, the others also accompany the growth of the flowers that have not yet developed.
Advantages and disadvantages
The slow release of these fertilizers allows the nutrients to be distributed evenly in the soil, thus achieving uniform plant growth. That is why this type of fertilizer is widely used by landscapers, who need to precisely control the growth of plants in order to achieve the planned design.
One of the greatest risks of an excess of fertilizers is the burning of leaves and roots, something that generally does not occur with this type of fertilizers because its precise and periodic doses allow minimizing the risks.
Many slow release fertilizers are solid and come in the form of powders and can feed a plant over a period of about three months. To apply them, they are mixed with the irrigation water, although there are also versions in tablets, the latter more risky as the nutrients are often not distributed evenly throughout the plant and can burn the areas that are close to the plant. tablet.
