What if our garden is not facing south? Well, the solution is to choose plants to grow in the shade or in partial shade. Hydrangeas are counted among the sciaphilous plants, that is, those plants that do not like direct exposure to the sun and that are able to thrive better in the shade.

The right soil
To plant one hydrangea in pot choose an acidophilic soil.
In case of planting in the garden, measuring the pH of the soil is not difficult. In the articlehow to lower the pH of the soilwe explain how to make a soil more acidic and how it can be measured with litmus papers for a few euros.
When to plant hydrangeas
The best period for planting in pots or in the garden falls in autumn and spring. Generally the plants are planted between October and November or March and April
The soil must always be kept moist. Hydrangea requires a lot of water, especially during the flowering period, avoiding water stagnation that can lead to the death of the plant.
Fertilizer for hydrangeas
L'hydrangea it feeds on potassium to grow healthy, and almost immediately consumes that naturally present in the soil, therefore fertilize the soil with a fertilizer rich in potassium and fertilizer for acidophilic plants.
When to fertilize hydrangeas? In early spring (between March and April) and in summer (between June and July), to support flowering.
On Amazon, a 2.5 kg package of this granular natural fertilizer can be bought for 13.08 euros with free shipping. For all the info: Neudroff granular fertilizer.
Among the variousfertilizers for hydrangeason the market, I pointed out the Neudroff granular organic fertilizer certainly not for the brand, but for its composition. Its formula sees a well-balanced blend of organic fertilizers:
NP (+ K) 7-3 (+6), Organic Nitrogen (N) 7.0%, Total Phosphoric Anhydride (P2O5) 3.0%, Potassium Oxide (K2O)
Perfect formula for acidophilic plants such ashydrangea, camellia, rhododendrons, azaleas, heather, bougainvillea ... Its solubility in water (6%) makes it perfect for prolonged action over time so as to limitfertilizationstwice a year.
I reported this product both for the formula and because it is a natural fertilizer. It should also be used at the time of planting of hydrangea.
I advise you to add it to the new planting holehydrangeas(100 grams) or give it to yourscultivation of hydrangeasalready started (25 to 75 g per plant, depending on the condition of the soil).
To ensure lush flowering is essential prune the hydrangea Once a year.

How to prune hydrangea? Removing the weakest branches to thin out the plant and cutting the flower stems of the previous year in half of their length, without touching the buds of the year (the younger ones) that have yet to bloom.
Flowering and colors
The flowers ofhydrangea “They change color” passing from a blue shade to a lilac or vice versa, this depends partly on the species but partly also on the elements that make up the soil: if acidic, the color changes towards blue, if alkaline, towards pink. The hydrangeas with white flowers, they are absolutely refractory to the composition of the soil and never turn blue. Very popular are the new hybrids:hydrangeaswith blooms of two colors, red hydrangeas, fuchsia or red and white hydrangea.

Hydrangea in pot, watering
