Lavender needs dry and sandy soil — it is also an ideal garden plant for dry summer. How to plant and care for the subshrub.

Origin

The Romans have used Lavender to prepare fragrant bath essences: The name of this plant is derived from the Latin word lavare, which means, "to wash". The English Lavender (Lavandula angustifolia) belongs to the Labiatae family (Lamiaceae), which also includes mint and sage. Its numerous varieties are classic summer garden plants.

The subshrub — a dwarf shrub that is woody only at the base — was originally native to the coastal regions of the Mediterranean. Found mainly on dry, warm hillsides. Most of the lavender species are also quite hardy as garden plants in our latitudes.

Out of the 25 known Lavender types, the hardy Lavandula angustifolia is mainly cultivated. However, "hardiness" is a relative term - in the wine-growing climate, lavender usually survives the cold season without any issues, but it needs protection in colder regions.

One of the best ornamental varieties is the Lavandula angustifolia “Hidcote Blue”. It was discovered in the 19th century in England in the well-known Hidcote Manor Gardens and has a naturally compact and very dense growth. The popular summer bloomer for containers and balcony boxes Butterfly Lavender (Lavandula stoechas) has striking bracts on the inflorescences. Unfortunately, it is not hardy.

Location and Soil

Lavender needs to be planted in a sunny, warm location in a nutrient-poor and well-drained soil. It is important that it doesn’t get too wet during winter, since it is very sensitive to frost.

Where to plant

You can plant Lavender as flower bed edgings or as rows of plants along walls and pathways. It grows particularly well in front of warm south-facing walls. As a fragrant plant, it enriches sunken gardens and is a popular summer bloomer for rock garden beds. It also fits perfectly with the Mediterranean garden style. Accompanying perennials can be, for example, Bearded Iris or Lamb's-ear. Lavender flowers are like a magnet for bees, butterflies and other insects in summer.

The Lavender is attractive not only because of the spike-shaped violet blooms that appear in July, but also the silver-grey lance-shaped leaves. Which make the Lavender attractive even after it has faded - especially as flower bed edgings where it unfolds its full charm and can also be kept in shape using garden shears.

Rose and Lavender are often planted together in flower beds, however, they don’t complement each other well: Although both are sun worshippers, they complement each other visually perfectly and Lavender also has the reputation of keeping aphids at bay. However, the plants differ significantly in terms of soil requirements: Lavender prefers nutrition-poor and moderately dry mineral soil, while Roses like to grow in humus-rich and loamy fresh soil that is not too low in nutrients. This problem can be solved by maintaining a planting distance of 31.49 inches to 39.37 inches and selectively making the soil lean in places where the Lavender is planted by adding construction sand. If you take the location requirements into consideration Woodland sages (Salvia Nemorosa) or Catmints (Nepeta x Faassenii) are a better choice.

Lavender in a pot

Lavender is also suitable as a potted plant for the terrace

It is possible to integrate the Spanish Lavender in potted plants. It has requirements similar to the English Lavender, but is usually planted as a classic balcony flower. It goes well with ornamental grasses and other structural plants and with white-bloomed balcony flowers. It is perennial like the English Lavender, but frost-free wintering is usually not worthwhile.

Southern France in particular is famous for its sprawling Lavender fields - to the writer Jean Giono, Lavender was the "Essence de Provence", the soul of Provence. Only a few know: In France, you will find Lavandin (Lavandula x intermedia), in addition to the English Lavender (Lavandula angustifolia).

Lavender oil

Lavender oil is also a raw material for perfumes, but is also suitable for oil burners and humidifiers. The oil is also said to have a wound-healing effect

Jean Valnet, military doctor in the French army, treated numerous burns and other injuries during the Indochina War (1950-1952) using Lavender oil. In his notes, he praised the excellent effects of Lavender oil on wound healing. As of now, over 160 compounds have been identified, which collectively bring out in the astonishing healing capability of Lavender.

Lavender tea is also a well-tried home remedy and soothes a wide range of complaints. Drinking Lavender tea, just before hitting the bed, is relaxing and give you a deep, sound sleep. Lavender tea has an antibacterial and anti-inflammatory effect and can also be used as a natural medicine against sore throat and throat infections. It is easy to prepare. Lavender tea relieves gas, bloating and abdominal cramps — a proven remedy for indigestion.

Lavender tea is easy to prepare: Put two heaped teaspoons of Lavender flowers in a tea ball, brew them with a quarter liter of boiling water and let the tea steep for about 10 minutes. The taste of pure Lavender tea takes some getting used to, but can be improved by adding other herbs such as Valerian or sweet Fennel. If possible, do not drink more than one cup a day, because Lavender tea in large quantities could damage the mucous membranes in the digestive tract.

Pruning Lavender

You need to prune Lavender regularly, otherwise it will rot and disintegrate. The first, light pruning of the plants is done immediately after flowering. In early spring, the Lavender is then aggressively pruned up to the woody parts. The plant will branch out at the intersections, and that way it remains compact and bushy. Since the subshrubs do not always tolerate pruning up to the old wood, well, an annual cut in early spring is important. In the early fall you can remove the withered flower stalks once more.

Additional care tips

Do not use any Fertilizer or compost. Lavender loves mineral soil and too many nutrients adversely affect the growth of the shoots, as the plants fatten and lose their stability. You only need to water your Lavender if dry conditions persist.

Winter protection

The key is a warm location protected from cold east winds and a well-drained soil so that the Lavender can survive the winter even in cooler climates. Winter wetness is particularly troublesome for subshrubs and can lead to them fall through. In fall, you must provide winter protection for the Lavender by mulching it at the stem base and additionally covering it with pine brushwood. Typically, protective measures are not required in the winegrowing regions.

As a potted plant, the English Lavender can remain outdoors all year round if you place the plant along with the pot in a location protected from wind and rain in winter, place the pot in a wooden box and fill it with insulating bark mulch. Water the Lavender on frost-free days only so much that the root ball doesn’t dry out.

Propagation

In spring, you can propagate Lavender from cuttings. These are a byproduct of pruning and it is best to root them in sand under a plastic wrap. The propagation of cuttings is still possible later in the season. Occasionally Lavender reseeds itself, but the offspring are then not true to variety.

Diseases and pests

Lavender is largely free of diseases and pests. Thanks to its essential oils aphids and avoid other insect pests. Snails don’t come either. The only disease by which the plants are more frequently attacked, in excessively humid locations is the so-called stem rot, which is caused by a fungus of the genus Phytophtora. If an infection is spotted in time, commercially available fungicides can help.
