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

Keep the soil lightly moist without saturating it: water when the surface dries, about once a week.

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.

Light

For this plant

Medium to bright indirect light. Outdoors, shade or part shade only.

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

Liquid organic feed every four weeks from April to October.

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 32 °C; protect it from hot, dry wind.

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

    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.

  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.
