Nutrients – for home growers

1.    What type of Gro-Expert fertiliser should I buy?

To make sure you’re buying the right fertiliser for your plants or crops; review your options by reading the Gro-Expert website or asking our experts what is correct for you.

Obviously if you plant is named on the box its relatively straight forward, however you may wish to grow pepper or cucumbers or even courgettes and so for advice it is best to ask. We will be expanding the range over the coming months so make sure to regularly check in with Gro-Expert to see what we will be bringing to you next.

2.    Can I store unused Gro-Expert fertiliser for use next year?

Yes, unused Gro Expert nutrients can be stored. Keep any leftover bottles sealed in its original container in a dry place away from frost for use next season. If moisture gets in, you may find the silicon has gone cloudy so best to keep all containers tightly closed.

3.    What are the three numbers on the plant food bottle and what do they mean?

The three numbers on the bottle of plant feed or lawn feed (such as 5:5:10 N:P:K) indicate the ratio of three key nutrients included in the fertilisers: nitrogen, phosphorus, and potassium, always listed in this order. Meaning, if a bag reads 5:5:10 N:P:K it contains 5 percent nitrogen, 5 percent phosphorus, and 10 percent potassium.

4.    Why is Potassium noted as K when it begins with P?

The reason potassium is noted as K is because the chemical symbol for Potassium is K. When the nomenclature for nutrient elements was being conducted, phosphorus was noted as P and Potassium was noted under the Medieval Latin name for Potash which was Kalium.

5.    What’s the difference between conventional fertilisers and organic fertilisers?

The difference between conventional and organic fertilisers is that conventional fertilisers are derived from minerals and organic fertilisers are derived from animal or plant based materials.
