So that hydrangeas shine in their proud bloom every year, a good supply of nutrients is important. With correct fertilization you can prevent or remedy a lack of nutrients. You can find out in this article what you should pay attention to when fertilizing, especially in summer.
What do I have to consider when fertilizing hydrangeas in summer?
As a rule, it is enough to fertilize hydrangeas once in the spring so that they are well supplied with nutrients all year round. If there is a nutrient deficiency, you can repeat the fertilizer application until July. From August onwards, if possible, you should stop fertilizing to protect the plant from frost damage.
When should you fertilize hydrangeas?
Hydrangeas need a good portion of fertilizer, especially inspring, in order to be adequately supplied with all the nutrients, especially nitrogen, that they need for vigorous growth and lush flowering. A special hydrangea fertilizer is best suited for this. Fertilization ideally takes place between March and May. Additional fertilizer applications are usually not necessary. However, if you notice a nutrient deficiency in your hydrangeas, you can also fertilize at a later date.
How often should I fertilize my hydrangeas in summer?
If you fertilized your hydrangeas in spring, fertilization again is in most casesnot necessaryHowever, if you have the impression that your hydrangeas are not receiving sufficient care or your soil is very poor in nutrients, you can repeat thefertilization
Particularly in late summer, you should use a slightly increasedPotassium content of the fertilizer. This promotes the woodiness of the shoots and thus prepares the hydrangeas optimally for winter. However, the amount of nitrogen should be reduced in summer as it promotes budding. For this reason, horn shavings are not suitable for summer fertilization of hydrangeas because they contain a lot of nitrogen and could cause frost damage to the plant.
When should hydrangeas no longer be fertilized?
FromAugust, hydrangeas should either only be fertilized lightly or not at all. The reduced availability of nutrients slowly prepares them for winter and the cessation of growth. If you want to fertilize again, you should make sure that the ratio of nitrogen to potassium is approximately 1:7. More nitrogen would harm the plant in winter.
Tip
Freshly planted hydrangeas are not fertilized
Hydrangeas that you have freshly planted are not fertilized in the first season. Because the roots have to actively search for nutrients, the root system develops better and branches more.
