All about hydrangea care

Hydrangeas are a type of plant that is included in the genus Hydrangea ; They are native to eastern and southern Asia, being able to find greater diversity in Korea, Japan and China.

Usually, they are a shrub that measures between 1-3m high, although we can also find them in forms of vines, even small trees.

If you are thinking about growing hydrangeas , the first thing you should do is inform yourself how it should be done. And, although the hydrangea care is not too complicated, the slightest mistake could throw your work to the ground .

We can help you with it.

Get to know hydrangea care


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

We introduce the hydrangea in the hole, and fill with soil until half of it. We add water and then the missing earth.

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

Temperature control

Probably the most complicated care hydrangea to control; If the plant does not get enough heat, it will not have the nutrients it needs to develop. On the other hand, if this heat is excessive, it may end up suffocated.

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 the indirect sun .

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

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


Another hydrangea care to be studied in detail is the type of soil that we are going to use: the soil must be porous, be moist and have a good level of drainage. In addition, fertilizer and compost should be added to the soil so that the plant evolves. The use of a layer of mulch is very useful for hydrangea to retain 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 outside temperature. If we live in hot climates, or we are in summer, it is normal to divide the irrigation into 3 parts , and in each of them add 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.

Type of fertilizer

The fertilizer will help the plant to bloom. Although it is true that we can find special fertilizers for hydrangea care , we can always opt for a fertilizer type 12-4-8 or type 10-10-10 .

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?

This is where we usually make the most mistakes, that’s why we explain it 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 leaf node. We immerse it in hormones and plant it in a pot that has moist and fertile soil. We cover with a plastic bag and protect it from direct sun.

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

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

With these simple steps you can avoid any problem of hydrangea care, in  addition to prolonging flowering as long as possible.
