All about hydrangea care

Hydrangeas are a type of plant that is included within the Hydrangea genus; They are native to East and South Asia and can find a greater diversity in Korea, Japan, and China.

In general, they are a shrub that is between 1-3m tall, although we can also find them in the shapes of lianas, even small trees.

If you are thinking of growing hydrangeas, the first thing you should do is find out how to do it. And it is that, although the cared hydrangeas are not too complicated, the slightest mistake could throw your work to the ground.

We can help you with it.

Learn about the care of hydrangeas


The hydrangeas should be planted in the spring or fall season. In order to do this, a fairly deep hole will have to be dug; As this term is quite ambiguous, we can calculate a ratio of 2-3 times wider than the root ball of the plant.

We introduce the hydrangea into the hole and fill half of it with soil. We add water and then the missing land.

As for the separation between plant and plant, it will be necessary to leave 90cm-3m as we want to organize the space.

Temperature control

Probably one of the most difficult to control hydrangeas; If the plant does not receive enough heat, it will not have the nutrients it needs to grow. On the other hand, if this heat is excessive, it can end up suffocating.

The hydrangeas prefer morning sun or the east. However, if the sun is abrasive in the area where you reside, then you will have to receive indirect sun.

Make sure they receive a minimum of 5 hours, otherwise they will never flower.

In relation to temperature, hydrangeas can only develop between 15 and 20ºC. They can adapt to colder places, but for this, they will have to receive enough heat.


Another care of hydrangeas that will have to be studied in detail is the type of soil we are going to use: the soil must be porous, humid, and have a good level of drainage. In addition, compost and compost must be added to the soil for the plant to evolve. The resource of using a layer of mulch is very useful for the hydrangea to conserve the moisture it needs.

Avoid places that are exposed to a lot of wind, since this external agent will negatively affect the growth of the plant.


The type of irrigation will depend on the temperature of the outside. If we live in hot climates or are in summer, it is normal to divide the irrigation into 3 parts, and each of them adds a minimum amount of water.

On the other hand, if we are in winter or in a particularly cold area, then you can space 1 irrigation in a frequency of 14 days.

Fertilizer type

The fertilizer will help the plant to flourish. Although while it is true that we can find special fertilizers for cared hydrangeas, we can always opt for fertilizer of the 12-4-8 type or the 10-10-10 type.

Important: Follow the instructions in detail to dose the fertilizer; if you add more product than you should, this will irreparably damage the plant.

 How to get the plant to spread?

At this point is where more mistakes are made, that’s why we explain it to you in detail.

We will have to start carving the roots, choosing a stem that is about 15 cm or so, and has no flowers. Use sharp scissors to cut below the blade node. We dip it in hormones and plant it in a pot that has fertile, moist soil. We cover with a plastic bag and protect it from direct sun.

We will simply check that the soil moisture is correct for 2-4 days and in about 2-4 weeks the stem will begin to form.

To end pests such as fungi, slugs, greenflies, or aphids, there are special products such as antifungal treatments, or you can even create your home insecticide.

With these simple steps, you can avoid any problem of caring for hydrangeas, in addition to prolonging the flowering as long as possible.
