Care
For each area, the instruction specific to this plant, then the general principle that explains why.
For this plant
Regular: two to three times a week in pots in summer, never letting it dry out fully nor sit soaked.
The principle
A moderate need asks for regularity rather than volume. Water when the top three to four centimetres feel dry: in practice weekly from May to September, every ten to fifteen days the rest of the year. Adjust for the pot — terracotta dries twice as fast as fibreglass.
For this plant
Full sun on the coast; in Marrakech, morning sun and light afternoon shade prolong flowering.
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
Potash-rich feed every two weeks from May to September to sustain flowering.
The principle
A fast grower exhausts its substrate quickly: a half-strength feed every two to three weeks from March to October beats one strong monthly dose. A new leaf smaller than the last almost always signals depleted soil or a pot that has become too tight.
For this plant
Ideal above 15 °C. Frost-tender: bring in or shelter potted plants below 5 °C in the interior.
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
Dry brown leaf tips and edges, foliage that droops late in the day and recovers overnight.
Likely cause
Alternating neglect and compensation: the root ball dries out completely, then receives too much at once.
The right move
Fix one watering day a week and check with a finger before you pour. Trim brown parts with scissors, following the leaf's shape; they will not turn green again.
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
Lower leaves dropping and tips browning in the weeks after a move or a change of season.
Likely cause
Adaptation stress: the plant is adjusting its foliage to a new quantity of light.
The right move
Change nothing for a month — no repotting, no feeding, no moving. Keep watering regular and remove only the leaves that are entirely dry.
