How to Fertilize Perennials This Spring

Just like people, perennials need nutrition to grow and bloom optimally. This nutrition can be provided in the form of fertilization. But how and when is this best done?

Basic requirements: The basic requirements of perennials are light, heat, water, and nutrition. A part of the nutrition is already present in the soil in the form of minerals; for the other part, plants depend on fertilization. Fertilize twice a year: in spring and in late summer.

Extra boost: Spring fertilizing is the most important: it is the foundation. Fertilizing in March gives your perennials an extra growth boost. Fertilizing in late summer (July/August) is necessary to give the plants strength before entering the winter period.

Top condition: Ask for organic fertilizer at your garden center or hardware store. Organic fertilizer has several advantages compared with chemical fertilizers. They allow plants to grow more gradually and improve the soil. Garden fertilizer, ornamental garden fertilizer, or border fertilizer are suitable for perennials. Check the packaging for the correct dosage; too much fertilizer actually gives weaker plants energy. Sprinkle the fertilizer on the soil near the plants. The fertilizer will allow them to grow and flower optimally and allow the soil to remain healthy and fertile. In this way, you can keep your perennials in top condition and enjoy them year after year. Tips:

• Do not fertilize when the foliage is wet; if the fertilizer sticks to the leaves, there is a risk of leaf burn.

• Also apply a thin layer of green compost to the soil.

• The foliage will tell you whether your perennial is getting sufficient nutrients. For example, smaller and lighter colored leaves indicate a nitrogen deficiency (N), and leaves that turn yellow between the veins indicate a lack of magnesium (Mg).
