How to Grow Lavender in Your Garden: Sun, Soil and Care

Growing a beautiful lavender plant has become a real ambition for many people who want to bring character and a distinctive scent to today’s back gardens. This Mediterranean species only needs a few straightforward steps to thrive and turn any garden into a genuine retreat.

Which species adapt best to our climate?

Worldwide, there are dozens of aromatic varieties found in nature, but only a handful manage to flourish successfully in Brazil. The stand-out choices in local conditions are the well-known Lavandula dentata and the elegant angustifolia.

These two particular plants cope well with higher temperature swings and the humidity typical of a tropical environment. They originate from a Mediterranean region, where summers are dry and winters tend to be noticeably cooler.

Below are some key points about what makes these aromatic plants so distinctive:

• Global varieties: There are twenty-five different species of this scented shrub around the world.
• National climate: Dentata and angustifolia are the species that adapt best to Brazil.
• Mediterranean origin: They come from areas with mild summers and considerably cold winters.
• Colder months: In tropical conditions, growth becomes much easier during winter.
• Early spring: The start of this flowering season is also an excellent time for healthy cultivation.

What is the ideal amount of sun for the plant?

Natural light is essential for this fragrant plant to grow vigorously and remain healthy in a home setting. To keep the shrub looking its best, the general recommendation is to provide at least eight hours a day of full, direct sun on its bed.

When it is grown in partial shade with limited light, the plant genuinely changes its usual structure. The stems stretch out in search of brightness, causing the leaves to become leggy and producing only a few flower spikes.

Below, there is a video from the Minhas Plantas YouTube channel that explores the points discussed in this topic in more depth:

How should the soil be prepared correctly?

To prevent excess water from damaging delicate roots, the main principle is to create a loose, open mix. The suggestion is to combine one part coarse sand with two parts of a specialist substrate designed for seedlings.

Coastal-style conditions

Efficient drainage

Because lavender originates from coastal regions, it prefers a lighter, sandier soil so it can grow without risk.

This blend helps prevent harmful moisture build-up around the roots during periods of heavy tropical rain.

If you are planting directly in the ground in the garden, dig a hole at least 20 cm deep. Space plants 40 cm apart to ensure excellent air circulation between each shrub.

Follow these essential guidelines to get spacing right in your bed:

• Avoid setting seedlings too close together to prevent early legginess.
• Keep the recommended minimum distance of 40 cm between plants.
• Make sure the chosen spot is completely free from the shade cast by large trees.

What essential care is needed for pots?

If you want to grow this aromatic shrub in containers on a balcony or patio, choosing the right pot is a major factor in success. Always go for a large model with at least 40 cm of depth and plenty of drainage holes.

When preparing the sandy mix, add a very generous amount of the high-quality organic fertiliser known as bocashi. It is important to leave the soil fully exposed and never use any protective straw mulch that would trap harmful moisture.

Here are the crucial rules for keeping a potted plant healthy over the long term:

• Use only spacious containers that allow thorough drainage.
• Mix in bocashi to supply the nutrients required.
• Keep the soil free of plant coverings so it can dry quickly.

How do you make new plants and revive the plant?

In mountainous areas or the colder regions of the south of the country, propagation happens easily from selected seeds sown straight into the soil. In most other Brazilian locations, it is best to take a green cutting from a branch that has already produced flowers.

If the shrub dries out completely in hot, humid and poorly ventilated tropical spots, a hard prune is unlikely to restore its health. In those unfavourable conditions, the better option is to choose another highly fragrant aromatic species to decorate your back garden successfully.
