Question: Camellia fertilization
I have on the terrace two vases of hydrangea (one white and one light pink) which, despite having taken steps to protect, have suffered a lot from the rigors of the past winter. One of them, in particular, has very small shoots that cannot develop.
I would like to know if a fertilizer with a high concentration of nitrogen (NPK 16 - 5 - 5 + Fe), which I use for other plants and that I know that favors the development of the leaves, can benefit (my doubt is due to the fact that it is acidophilic plants and therefore I know that there are special fertilizers for these plants, with a much lower percentage of nitrogen).
I would also like to know if, during the flowering period, always for hydrangeas (I have another one on the terrace - with a much larger pot, which is instead very luxuriant), and for the above discussion, I can use another fertilizer with a high concentration of potassium.
Thank you very much
Answer: Fertilizing Camellias
Thank you for contacting us about hydrangea fertilization questions.
Hydrangea belongs to the Hydrangeaceae family and originates from China and Japan.
It is a rustic shrubby plant with large deciduous leaves with a toothed margin.
It normally blooms from July to September with typical globular inflorescences of color that can be white, pink or blue and within a certain variety, the color of the flowers can vary according to the type of basicity or acidity of the soil.
In order to grow well and bloom in a luxuriant and intense way, they prefer preferably acidic and fertile soil, shaded positions, sheltered from the wind and frost, require considerable water availability.
With regard to your specific it is advisable to make an initial fertilization with formulas that favor the vegetation associated with formulas based on amino acids which favor the prompt recovery of the plant from the block caused by thermal factors (cold stress). At a later time, it is recommended to use a specific hydrangea fertilizer that brings the right ratio of nutrients. Eventually an integration is made with the flower color intensifiers. We also advise you to check that the roots of the decayed plant have not been damaged by the cold, and if this hypothesis were founded it is advisable to intervene with a repotting.
