To strengthen your plants, we are looking for different ways to take care of them best. Many people recommend fertilizing specimens with a fireplace ash. In the case of hydrangea, however, this may be a wrong idea.
Although many plants will appreciate the natural fertilizer, which is ash from the fireplace, it will not work in the case of hydrangea. This is due to the fact that it raises the pH of the soil, and these plants prefer acidic substrate. So this means that the use of wood ash for hydrangea can make it stop blooming.
This is the result of the fact that Too high soil pH prevents these specimens from taking nutrients. This leads to the general weakness of the plant and the cessation of releasing new ones. Ash is better for specimens that like the alkaline reaction of the substrate, such as roses, lavender or tomatoes.
It is also worth mentioning that ash from the fireplace can affect our hydrangeas. This is because it has strong deacidification properties, so as we mentioned, it raises the pH of the soil, and that’s it The level of earth acidity affects the color of hydrangea.
In sour soil they are blue, and in an alkaline substrate they bloom pink. Therefore, if we dream of intensively blue flowers, The ash spreading can not achieve this effect, and the color of hydrangea will change to pink or faded violet.

Knowing that the ash from the fireplace is not the best fertilizer for hydrangea, It is also worth being aware of what we can feed our plants in the summerwhen they are undergoing vegetation and need our support to bloom and keep a healthy habit.
Then It is worth reaching for multi -component fertilizers, which are dedicated to hydrangeas. They contain phosphorus, potassium and nitrogen in balanced proportions and abound in microelements. Wanting to keep the blue color of the flowers, We should choose fertilizers that have the addition of sulfur or aluminum sulfate.
Fertilization should be performed every 2-3 weeks until the end of July. From August, we have been giving up products containing nitrogen, exchanging them for autumn fertilizerswhich are rich in phosphorus and potassium and prepare the plant for winter rest, supporting its immunity. Let’s also remember to moisten the soil before watering with fertilizer. Thanks to this, we will avoid root burns.
