Watering and repotting tropical pitcher plant through the year

It lives indoors all year, so it has no sowing or planting dates: it grows from March to September and rests from October to February (the other way round in the southern hemisphere).

Repot it about every 12 months.

When to plant tropical pitcher plant?

Plant or repot tropical pitcher plant in spring, as it starts into growth; early to midsummer also works. It is a houseplant, so it has no outdoor planting date and no frost decides it: just avoid autumn and winter, when growth slows and fresh compost stays wet too long. After that, move it to a slightly larger pot about every year, or sooner once roots circle the pot or grow through the drainage holes.

Growing notes

Light

Bright filtered light in partial shade, for example by an east- or north-facing window.

Soil

A loose, acidic, low-nutrient mix such as bark, sphagnum-type moss and charcoal, or sphagnum with perlite; garden soil is not tolerated.

Care

Water only with rainwater or distilled water, because tap water harms it, and keep the mix moist but never standing in water. It needs warmth and high humidity (lowland kinds like about 21–35 °C, highland kinds 24–29 °C by day and cooler nights); when the air is too dry the pitchers stop forming or die back. It needs no fertiliser, and do not feed it meat. Trim off spent pitchers. Keep it in its pot for at least the first year and repot once the roots fill the container. Propagate by stem cuttings in February.
