You need to have an updated idea about that.

A regular gardener has to have an immaculate idea about fertilizers. But you are new to gardening let me tell you, you have got to learn a lot especially about fertilizers and expiry. Do keep in mind that:

  • The sustenance of fertilizer depends on the type of soil and the type of fertilizer also.
  • Usually, dry fertilizer lasts 4 years approximately
  • Liquid fertilizers have a longer life span that is about 10 years.

Usually, fertilizers that are made up of potassium, nitrogen, and phosphorus do not degrade easily. so they have quite a long sustenance per application. These elements do not degrade easily. So the lifespan is indefinite in such cases. But the presence of herbicides and pesticides shortens the life expectancy to four years.

Liquid fertilizers:

Fertilizers in the form of liquid work great as both plant and soil fertilizer supplying more than 80 plus nutrients in minimal amounts. The process of absorbing the nutrients through liquid fertilizer is quite a lengthy process and lasts for a longer period of like 10 years. But on the contrary, compared to dry fertilizers the liquid fertilizers are absorbed faster.
Liquid fertilizers are found.

The process of absorbing nutrients through liquid fertilizers:

As liquid fertilizers do not have any pesticides or herbicides their decomposition period takes place from at the end of 8 to 10 years. The process starts with applying it to the soil. Then it is absorbed by the roots of the plants supplying all the essential nutrients. But note that the faster it is absorbed by the soil the slower it takes in case of nutrients’ absorption but has a long life span so how long does liquid fertilizer last?

This life span is only applicable when you store them properly.

The lifespan of fertilizers greatly depends on the components of the fertilizer. As told before the presence of herbicide and pesticides can readily shorten the decomposition of the fertilizer. Whereas the stable elements result in a longer period of sustenance.
