You should fertilize your maple once a year. Vitality, resistance and winter hardiness benefit equally from a well-balanced nutrient supply. This guide gets to the heart of when and how to properly fertilize a maple tree.

The ball maple does not necessarily have to be fertilized

The best time is in autumn

As a refinement of the Norway maple (Acer platanoides), a maple does not depend on fertilizers to promote its growth potential. Rather, a supplementary supply of nutrients is subject to the task of strengthening frost hardiness and resistance to diseases. Because of this, early fall is coming into focus as the best time to apply fertilizers.

Potassium-rich, organic fertilizer is the trump card - tips for the composition

Strong-growing spherical maple varieties can confidently do without nitrogen, the engine of growth. In order to be prepared for the hardships of winter, the right fertilizer should have plenty of potassium in its luggage. This main nutrient has the property of strengthening cell walls and lowering the freezing point in the plant sap. Mineral artificial fertilizers are taboo for the ecologically oriented gardener, so this nutrient supply has turned out to be ideal:

  • Distribute 3 liters of mature compost per square meter between the end of August and mid-September
  • Work in the fertilizer superficially with the rake
  • Shower with potassium-rich comfrey manure

Home gardeners without a compost heap and the ability to make comfrey manure resort to Patenkali, also known as Kalimagnesia. If you cultivate your maple in the tub, we recommend the administration of liquid potassium fertilizer, such as Purital.

Initial fertilization stimulates growth - this is how it works

If you think about an adequate supply of nutrients when planting, a maple tree will unfold in all its glory right from the start and give cunning fungal spores the cold shoulder. Line the planting pit with comfrey leaves and mix the excavation with compost and horn shavings.(32.93€) Then water generously so that the organic nutrients are fully absorbed.

tips

Norway maple thrives with a heart root system that extends far more in width than depth. In order to motivate the roots to grow deep, it is better to water less frequently and thoroughly than frequently and superficially. In summer dry conditions, run the hose for at least 30 minutes twice a week.
