Hydrangeas are one of the most popular flowering ornamental shrubs. In gardens, parks and city squares, bouquet hydrangeas, tree hydrangeas, garden hydrangeas and those planted at climbing supports are the leaders, and enthusiasts can also try to obtain less frequently cultivated oak-leaved or serrated hydrangeas.
The species and varieties of these shrubs differ significantly in the structure and color of inflorescences, achieved sizes, flowering time and method of pruning, but their requirements for the substrate are very similar.They should be planted in well-drained, fertile and fairly moist soil with a high content of humus and acidic pH.
Remember, however, that the macro and microelements contained in the substrate are constantly absorbed by plants. If we do not take care of the annual supply, their amount will run out with each season, leading to a weakening of the plant.The possibility of absorption of macronutrients by hydrangeas, related to the form of the elements supplied, is also important.Equally important is a balanced the nutrient content of the fertilizer. Too low a ratio of potassium to nitrogen results in poor flowering despite vigorous vegetative growth.
It is worth knowing that for proper growth, hydrangea needs both fertilization and acidification.Instead of buying two products unnecessarily, let's reach for the latest "2-in-1" solutions, for example a fertilizer of this type, unique on the market, which is enough apply only once per season!
This multi-ingredient acidifies and fertilizes, moreover, it works for a long time, gradually releasing nutrients. What is extremely important, it contains two separate fertilizers that create optimal conditions for the development of hydrangeas.Provides long-lasting effects, and another advantage is that it is extremely efficient.
To choose from
The reaction of the substrates is of key importance for the hydrangea. All species belonging to this genus prefer acidic soils.Moreover, the pH value directly influences the color of the inflorescences of many varieties of garden hydrangea. With the exception of white flowering forms, in this species the color of flowers depends on the content and the possibility of taking up aluminum from the substrate. The ions of this element responsible for the blue color are released as acidification increases.
In soils with a pH of around 5.0-5.5, hydrangea inflorescences will be pink, with a decrease in the pH value, they turn purple, while blue inflorescences appear in plants growing in soil with a pH similar to up to 4.5 or just a tad higher. If we dream of wonderful blue hydrangeas, just use acidifying fertilizer in the right dose.
