Care

What this plant needs

For each area, the instruction specific to this plant, then the general principle that explains why.

Water

For this plant

Let the soil dry halfway down the pot between waterings, roughly every ten to fourteen days.

The principle

A low need means a clear dry-then-wet cycle. Wait until the top two thirds of the substrate are dry, water until it runs from the base, then empty the saucer ten minutes later. Permanently moist soil suffocates roots far faster than dryness starves them.

Light

For this plant

Medium to bright indirect light. It accepts a slightly dimmer corner without losing its shape.

The principle

Partial shade is bright but filtered light: a metre back from a glazed door, behind a sheer curtain, or morning sun only. It is the broadest and easiest exposure to achieve in a Moroccan interior. Direct afternoon sun, by contrast, leaves irreversible bleached patches on the leaf.

Feeding

For this plant

A liquid organic feed every six weeks from March to September.

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.

Temperature

For this plant

From 15 to 30 °C; avoid sudden temperature changes and draughts.

The principle

This plant is comfortable between 15 and 30 °C, the range of a Moroccan interior all year. Above 35 °C, move it out of direct sun and water more often without watering more heavily. The most common enemy is not the heat but the dry stream of an air conditioner aimed at the foliage.

Diagnosis

Three signals worth reading

The three most common disorders on a plant with this profile, and the move that corrects them.

  1. 1

    What you see

    Lower leaves turning yellow and dropping at the slightest touch while the surface still feels fresh.

    Likely cause

    Watering too close together: the roots never get to breathe between two doses.

    The right move

    Switch to a clear cycle — dry through two thirds of the depth, then a thorough watering with full drainage. Always empty the saucer and raise the pot on feet if needed.

  2. 2

    What you see

    Bleached then brown patches in the middle of the most exposed leaves.

    Likely cause

    Direct afternoon sun through glass — the magnifying effect scorches the blade in a matter of hours.

    The right move

    Pull it back a metre or hang a sheer curtain. Marked leaves will not repair, but the next ones will be clean; remove them only if more than half is scorched.

  3. 3

    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.
