Fertilizers

| Les Serres Dauphinais

We have had the opportunity to test several fertilizers over the years. Our strong experience in the horticultural field has allowed us to select some of the most efficient fertilizers while being the easiest to use for you.

General information

Fertilizers have always three numbers. What do they mean? They are percentages indicating the minerals that are contained in the chosen fertilizer and the quantity of these minerals.

The first number

The first number on the left is always the % of nitrogen in the fertilizer. Nitrogen is an essential element for the development of any plant. It is the main component of chlorophyll and proteins that will stimulate plant growth. A plant that receives enough nitrogen will have beautiful, strong, brightly colored foliage. Its stems will be strong.

The second number

The middle number represents the % of phosphorus that the fertilizer contains. Phosphorus is the mineral that promotes the development of the plant’s roots. It promotes efficient transplanting and the development of the plant. It is used to make the plant stronger and to promote the eventual production of flowers or fruits.

The third number

The last number on the right represents the % of potassium in the fertilizer. Potassium helps regulate the plant. It allows the plant to assimilate chlorophyll, to resist diseases and bad weather. This mineral will allow your plants to produce flowers or fruits in abundance all summer long.

Here are the different fertilizers we sell and their uses

All-purpose fertilizer 20-20-20

This is the basic fertilizer for all plants. It is used at the beginning of the season to promote the growth of strong and healthy plants. It is relevant for annuals, garden plants and fruit trees. It is often recommended to alternate it with 20-5-30.

This fertilizer is water-soluble. It is added to the watering water. It is necessary to put about one tablespoon per 4 liters of water. You can also get a dispenser to connect to your garden hose.

Flowering fertilizer 20-5-30

This is the fertilizer that promotes the production of flowers and fruits. At the beginning of the season, it is alternated with the 20-20-20 so that the plants get stronger. The more the season advances, the less the 20-20-20 is used. At the end of the season, we use only the 20-5-30.

This fertilizer is water-soluble. It is added to the watering water. It is necessary to put about one tablespoon per 4 liters of water. You can also get a dispenser to connect to your garden hose.

Slow Dissolving Fertilizer 14-14-14

Slow-release fertilizer is a solution for those who do not wish to mix fertilizer with water and apply it often. This fertilizer is used only once or twice throughout the summer. It is mixed into the soil when planting and then dissolves over the course of watering. It helps the plant gain strength, and it provides the basic nutrients that are needed throughout the summer.

The last number (potassium) is lower than for the 20-5-30, so this fertilizer is not as beneficial for flowering, but it remains a good compromise when you don’t want to fertilize often.

Tomato fertilizer 12-2-14 enriched with calcium

Tomato is a plant that requires a lot of calcium. The use of a tomato fertilizer enriched with calcium is necessary to avoid the formation of black spots on the fruit.

This fertilizer is water-soluble. It is added to the watering water. You need about one tablespoon for every 4 liters of water. You can also buy a dispenser to connect to your watering hose.

Fertilize tomato plants every 2 to 3 weeks with this fertilizer and alternate with 20-20-20 or 20-5-30.

Rooting fertilizer 10-52-10

The rooting fertilizer is very strong in phosphorus. It is used to promote the rooting of plants during transplanting. It is not necessary to use it for all types of plants. It is mainly used for transplanting shrubs or perennials that have been in place for a few years and that we want to move or when we plant a tree.

This fertilizer is water-soluble. It is added to the watering water. It is necessary to put about one tablespoon for 4 liters of water. You can also buy a dispenser to connect to your garden hose.

It is used only once during transplanting.
