Caring for hydrangeas

Hortensias

Hydrangeas are among the favorite flowers of gardening fans. With their beautiful colors they are the perfect decoration for your garden or for the interior of your home. However, if you are going to grow hydrangeas, you will need to give them some important care so that your flowers can grow healthy. Read on to find out what you should look out for when caring for hydrangeas.

Lighting and temperature for your hydrangeas

The first thing you should know is that hydrangeas need to receive natural light, but not too much. If your home is in a hot area, position your hydrangeas so that they are not exposed to direct sunlight. It is best to choose a location with some shade for your plant. Subjecting your hydrangeas to too much sun or shade will affect your flower buds.

As for the ideal temperature, hydrangeas prefer temperate climates. If you are going to have hydrangeas, it will be a great advantage if you live in a place that stays below 20°C but above 15°C. If not, don’t worry. Hydrangeas can adapt to the cold.

If you live in a place that is too hot, you should water them more and protect them from the sun.

Watering

Hydrangeas love water. Water them constantly to keep the soil moist. In hot climates or seasons you can water them up to once a week. In colder climates, you should only water them once a month. We recommend that you use rainwater for irrigation.

Try not to get the leaves and flowers of the hydrangeas wet when watering, as this can cause them to become sick. Also avoid giving them too much water, as their roots could rot.

Keep in mind that some hydrangea species need more water than others. Also, if you have just planted your hydrangeas, you will need to water them more frequently.

Soil

As we mentioned before, hydrangeas need a soil capable of maintaining moisture. In addition, the soil must have good drainage so that it does not remain waterlogged and damage your plant. The ideal way to achieve these characteristics is to use a substrate of organic composition with an acidic PH.

As a curious fact, we comment that the color of your flowers will depend on the acidity of the soil. When the pH of the soil is low, the flowers will probably be blue. On the other hand, if the pH of the soil is high, the flowers will be pink. Whatever the colour, hydrangeas require the same care.

Fertilizer

Give your plant some fertilizer annually. You can use an organic fertilizer such as compost or a special hydrangea fertilizer from your favorite garden store. However, don’t overdo the fertilizer or you’ll make your plant sick. It’s best to start with a low dose of fertilizer.

Prune

Use scissors or tweezers to prune your hydrangea plant annually. Take the opportunity to remove old flowers and branches.

Curiosities and additional care

Blue hydrangeas

As we have already mentioned, the colour of hydrangeas depends on the acidity of the soil. If you have pink hydrangeas, but want blue ones, you can go to your favorite garden store and buy some sulfur compound for gardening. Sulfur will lower the pH of your hydrangea’s soil, making the pink ones change color to blue.

White hydrangeas

White hydrangeas are just that, white hydrangeas. You won’t get these to change color.

Yellow leaves

If your plant’s leaves are yellow, something’s not quite right. You may be using water that is not suitable for watering your flowers, for example. As mentioned above, we recommend that you use rainwater for watering. This is because tap water can contain minerals that can damage your hydrangeas.

On the other hand, it can happen that the soil is deficient in the nutrients the plant needs. This deficiency is usually iron, and you can solve it by providing this mineral to the soil. You can buy iron compounds for this in garden shops.

Large pots

If you’re growing your hydrangeas in a pot, it should be wide enough. Hydrangeas grow very large, and they will need a large enough space to develop.

Diseases

There are many pests that can damage your hydrangeas. Use an insecticide recommended by garden shops, depending on the pest that is affecting your flowers.

Remember to prune both flowers and leaves that show signs of disease, otherwise the plant will continue to be damaged.
