Lavandula angustifolia
A grey-blue cushion with an unmistakable scent, at home in bright sun and dry soils.
At a glance
Care
For each area, the instruction specific to this plant, then the general principle that explains why.
For this plant
Water only once the soil is dry deep down; weekly in pots in summer, almost never in the ground after the first year.
The principle
Plants with very low water needs store reserves in their leaves, stems or roots. The risk is never thirst but excess: let the substrate dry through its full depth, water generously in one go, then wait two to four weeks. In winter, once a month is almost always enough.
For this plant
Full sun is essential. In shade it grows leggy and flowers poorly.
The principle
Full sun means six hours or more of direct light a day. These plants build thick foliage and dense tissue to cope with it; in insufficient light they stretch, lengthen their internodes and lose their compact habit. After buying or repotting, reintroduce direct sun gradually over ten to fifteen days to avoid scorch.
For this plant
No fertiliser needed. Poor, chalky soil intensifies the scent.
The principle
Moderate growth is fed once a month from March to September with a balanced liquid feed at the maker's dose. Water with plain water first, then feed: on dry substrate, concentrated fertiliser burns the fine roots. Nothing from October to February, the resting period.
For this plant
Hardy to −15 °C and comfortable up to 40 °C, provided the roots never sit in water.
The principle
Good heat tolerance means the summers of Marrakech, Fez or Béni Mellal pose no problem as long as water follows. Days above 38 °C call for early-morning watering and, in a pot, protection of the west-facing wall: the root ball can reach 50 °C before the plant shows anything at all.

Diagnosis
The three most common disorders on a plant with this profile, and the move that corrects them.
What you see
Soft or brownish stem bases, translucent leaves, substrate still damp a week after watering.
Likely cause
Too much water. On this profile, crown rot beats drought as a cause of loss by a wide margin.
The right move
Stop watering entirely, unpot, cut away brown soft roots, air-dry the root ball for a day, repot in a very free-draining mix and wait ten days before the first watering.
What you see
Stems stretching towards the window, long internodes, new leaves smaller and paler.
Likely cause
Not enough light. A full-sun plant three metres from a window receives less than a tenth of what it asks for.
The right move
Move it to the brightest glazing or out onto a balcony, reacclimatising it to direct sun over two weeks. Cut back the stretched shoots: it will regrow compact.
What you see
Grey dust on the foliage, growth slowing with no obvious cause.
Likely cause
A dusty blade captures markedly less light, and city dust in Morocco builds up fast.
The right move
Wipe the leaves with a damp sponge every month, upper and lower surfaces. Avoid leaf-shine products, which block the stomata.
