Fertilize fruit trees properly


The Content Of The Article:

Basically, you should be cautious when fertilizing your fruit trees - especially when it comes to using nitrogen-rich fertilizers. They promote vegetative growth, ie the development of shoots and leaves. At the same time, the trees set fewer flowers and subsequently produce fewer fruits. Above all, the nutrient phosphate is required for flower formation - but like the potassium that is important for fruit development, it is sufficiently present in most garden soils. Especially an oversupply of potassium should be avoided at all costs. It affects the calcium intake and is - in addition to a calcium deficiency in the soil - a cause of Fleischbräune and stippige fruits. If you do not know the nutritional content of your soil, you should have it examined: The soil labs not only analyze nutrient levels, but also give specific fertilizer recommendations.

Organic or mineral fertilizer?

As a starting fertilizer, simply sprinkle with corn grit mixed ripening compost, rotten cattle manure or pelleted cattle manure under the treetop in the spring - but only in the outer third of the canopy, because near the trunk, the trees have hardly fine roots to absorb the fertilizer. During the growing season, it is best to fertilize with an organic fruit and berry fertilizer. Long-term fertilizer with sheep wool pellets improve the water storage capacity of dry soils.

You can of course also fertilize mineral and stone fruit minerally. Because these fertilizers dissolve faster and do not have such a lasting effect, you should divide the total amount by the end of July on several gifts.
