Lavender care: irrigation, cultivation and pruning

Lavender is one of the aromatic plants’ par excellence, perfect to have at home. The post was prepared by our friends at McKenzies’ family blog. The care Lavender is not too complicated; and not only provides us with the pleasure of enjoying the natural beauty of this plant but also its greatest virtue: its peculiar and irresistible perfume. It is an aroma that smells like summer, nature, and a source of natural medicinal remedy.

A being a wild bushthe Lavender is a rustic plant character that will not require much from us to flourish in the summer months. Moreover, it is important to know that this plant is even able to grow in rocky areas and in full sun, so this gives us a good clue of its few needs.

Let’s discover what they are to enjoy this wonderful plant at home!


Lavender in any of its varieties (there are more than 60 types) is perennial, so its leaves will not be renewed annually. Able to reach one and a half meters high, this plant is a shrub that will acquire a woody character. This makes Lavender ideal for forming beautiful closures and borders (which will be even more striking with the arrival of its unique flowering).

Something we can achieve by following five simple steps to grow this wonderful plant:

1. What type of substrate does Lavender need?

Lavender not only needs an alkaline substrate (or, what is the same, with a high pH ) but also is essential for its correct growth. In case our soil is acidic, we will have to compensate for that acidity with a specific substrate (which we will have to apply on a recurring basis) or, even, adding lime to raise the pH.

In addition to making the plant have this type of substrate to grow, it is essential that the Lavender has good drainage. For this, the ideal is that we procure a sandy soil (which facilitates the evacuation of water, preventing any trace of moisture). This aspect is especially important since the roots of the Lavender do not tolerate waterlogging at any time of the year, but especially in winter (when an excess of water in the roots can freeze them and kill the plant).

2. Where to plant Lavender?

There is no specific place but, rather, one that meets the necessary conditions. By this, we mean that both in a pot (something that we will have to choose carefully: it will need to have a diameter of between 30 and 40 centimeters) and directly on the ground, it is possible to plant Lavender and enjoy it successfully. What is important is that the plant has good aeration, what is the same, that when we propose it, we not only avoid doing it very close to other plants but also foresee the dimensions that it can reach when it begins to grow (with a view to keeping a certain distance from any other plant). In this way, you can grow normally without hindering the growth of your neighbors.

In addition, it is essential that the plant receives direct sun for at least six hours a day. A good reason to avoid, if we plant it on land, that it is close to trees that can steal luminosity.

3. How should Lavender irrigation be?

Given its rustic character, in nature, Lavender endures even times of absence of water. However, we will have to pay attention to your irrigation pattern, especially in the months of growth in which we will have to provide moderate irrigation. It is important that we water it always avoiding wetting its branches and flowers, since doing so, we run the risk of fungal growth in the plant.

During the cold months, we will space the risks and concentrate them in the central hours of the day to avoid that, with the arrival of the night, their roots can still keep moisture. In the hot months, the ideal is a regular watering once a week, and as long as the substrate is dry before doing so (if it still retains moisture, we will wait a little longer before watering again).

4. Is Lavender paid?

Well, no, it is more advised against! As a good rustic bush, it is not too demanding in terms of soil quality, and excessive fertilization can cause its flowering to lose its powerful characteristic aroma. However, if the soil on which it is planted is very poor or for those potted specimens, it is advisable to apply a minimum fertilizer solution before the flowering season.

5. When is Lavender pruned?

And if fertilizing the plant is not important, it is pruning. This is something that we should not confuse with picking your flowers (if the destiny of these is to have decorative or even medicinal purposes). With the beginning of spring or the arrival of autumn (always before or after the flowering season), it is best to perform a small pruning that will never exceed half the size of the plant. Thanks to her, we will be stimulating the growth of new branches but also of her flowers.

This same task will be performed in those lavenders that are arranged creating a closure or bordura, with a small difference: in addition to pruning it in height, we will have to do it in contour (with a view to giving it the shape we want, and that the whole closure follows a same aesthetic line).

And with these five steps to cultivate Lavender, it will be rare for us to resist being able to count on its wonderful fragrance during the summer months. One that is also a true magnet for the biodiverse fauna that lives in the garden and is so necessary for the sustainability of nature.
