The four most important at a glance

Here are the four most important rhododendron fertilizers

• Mineral fertilizer Blaukorn Entec
• Organic complete fertilizer
• Horn shavings
• Cattle manure

First test then fertilize

Before the Fertilize first test the pH value of the soil using universal indicator paper. This prevents overfertilization and you know whether more or less rhododendron fertilizer is needed.

Mineral fertilizer or organic fertilizer?

As shallow roots, rhododendrons cannot use nutrients from deeper soil layers. If they are to bloom profusely, they must be properly nourished. The combination of mineral ingredients has proven to be very effective Complete fertilizer like blue corn Entec and an organic fertilizer. The blue grain works for two to three months. The amount depends on the size of the plant. In addition to the complete fertilizer, the same amount of coarse

Blue grain in small pinches under the ornamental shrub on the Earth distribute as the nutrients and salts concentrate in the soil area. Use blue grain as fertilizer during the growth and vegetation phase in spring. In the growth phase, the plants convert the minerals more quickly and utilize them more quickly. Water the plants well so that the salts dissolve and are transported via the roots. Or put the blue grain globules directly into the watering water. An amount of 5 grams per 10 liters of water is sufficient for fertilization in the growth phase. Do not treat young plants with blue grain. The tender roots are quickly attacked and the plants perish.

Rhododendron substrate

This special soil with a low pH value is specially tailored to the needs of popular bog plants such as rhododendrons. Enriched with fertilizer, it supplies the plants with nutrients for up to three months. Including additional iron for green, robust leaves and more flowers. Place the plant in the center of the planting hole. Make sure that the roots can spread. Fill the planting hole with rhododendron substrate. Now pound in the earth and water - done.
