When growing blueberries, it's clearly about the delicious blue berries. If the bush doesn't bear fruit, there's a lot of trouble. Since there are various causes for the bad harvest, you should get to the bottom of the matter.
Why don't blueberries bear fruit?
Thereasonsfor this arediverse. Location, soil and/or care errors (lack of nutrients, dryness or waterlogging) can be the cause. Late frosts can also destroy the harvest, as the blueberry flowers cannot tolerate frost.
How do location and soil affect the blueberry harvest?
cultivated blueberriesneedasunny to semi-shady locationIf the blueberry bush gets too little light, it will produce few or no flowers. In addition, old and/or inwardly growing branches can block the sun's rays from the inside of the bush.
As a heather plant, the blueberry needs aslightly acidic soil Since normal garden soils in our area are usually calcareous, the shrub grows poorly and has too little energy to develop flowers and berries. It is therefore recommended to plant blueberry plants in rhododendron soil.
Can drought lead to a poor blueberry harvest?
Blueberries in the bog beddo not tolerate drought That is why you should also water planted bushes with lime-free water during longer dry periods. To reduce moisture loss, you should cover the root area with bark mulch. In container cultivation, a regular water supply is essential for fruit formation. Keep the substrate moist, but do not give the cultivated blueberry too much water, as waterlogging will cause the plant to die.
Do I have to fertilize the blueberries?
Blueberries bearno fruitif you suffer fromnutrient deficiencies. The most common deficiency symptom is iron deficiency. In order to optimally supply the blueberry bush with nutrients, you should fertilize it regularly with a special fertilizer for blueberries.
Tip
Cross-pollination promotes fruit formation
Cultivated blueberries are self-pollinating, but combining different varieties increases the harvest due to cross-pollination. To ensure that the berry bushes get enough light, the distance between the blueberry plants should be at least 70 cm.
