Overview:
Spathiphyllum floribundum* is an evergreen indoor perennial, that flowers between May and August.
*Not to be confused with Anthurium andraeanum( hence to the two photos!)
They prefer a lightly shaded position in summer with relatively high humidity, and maximum light in winter.
Ideal temperatures are 21°-24°C(70°-75°F) in summer, and 13°-16°C (55°-60°F) in winter, and idealy plants should be kept out of draughts!
Grow in 150mm (6") diameter pots, containing compost equal to John Innes No 2.
Re-pot them in April (Week 16) every two to three years, to freshen and revitalise the growing medium.
Watering:
The soil should be kept moist but never soggy.
Water the plants regularly when in full growth, but less frequently in winter.
Allow the soil to dry out slightly between waterings, but excessive drying can make the plant to wilt and cause yellowing of leaves.
When watering, it is very important to use room temperature water.
It is also a good idea to allow the water to absorb up from the bottom without wetting the foliage.
Do this by standing the pot on a plant saucer of moist grit, but on no account allow the pot to actually stand in water or the roots may rot.
This method will also improve the humidity around the plant.
Feeding:
Feed with a half strength balanced feed at fortnightly intervals from March (Week 12) until September, and half strength once a month during winter months.
Overfeeding can burn the leaf tips.
Aftercare:
Cleaning the leaves regularly with a damp cloth to remove accumulated dust tohelp the plant breathe.
This will also remove any pests that may have gathered on the underside of the leaves.
