One of the easiest orchids to grow, moth orchids (phalaenopsis) make reliable houseplants. They flower up to three times a year, each flower lasting several weeks

Q Where's the best place for moth orchids (phalaenopsis)?

A Choose a semi-shaded spot away from direct sunlight; a west or east-facing window is ideal. They like temperatures of 15°C minimum by night, a maximum of 30°C by day and do well in centrally heated homes. Fluctuation between day and night time temperatures is vital to encourage flowering. Humidity is also important, so stand plants on a tray of wet pebbles - but not in water. On warm, mornings you can mist them – no later though, as the foliage must be dry by evening.

Q How should I feed and water a moth orchid (phalaenopsis)?

A Keep slightly moist at all times but never wet. Water once a week during summer if needed but less in winter. Always do this from the top of the pot, and use tepid rainwater or filtered tap water. Don’t use cold water as it can shock a plant and don't water the crown as this can cause it to rot. Feed your plant once a month using a balanced liquid plant feed at a quarter of its usual strength.

 Q How can I get my moth orchid (phalaenopsis) to flower again?

A Flower spikes often branch and produce further blooms. Cut the spike off just below where the first flower appeared, just as the last one is beginning to fade. Then cut the entire spike off at the base when it has withered.

Q How do I repot my moth orchid?

A These orchids don't out-grow their container they just need the compost refreshed every two or three years. Do this in the spring. Tip the plant from its pot, tease out all the old compost and roots, then cut off any damaged or decayed roots. Repot in the original container (no larger than 12-15cm across), gently packing fresh orchid compost around its roots. To help re-establishment, water sparingly for six weeks, until it feels firmly rooted.
