How to Use

Potting and re-potting

  • Choose a pot with just enough room for the roots.

  • Fill one third of the pot with orchid potting mix. Place the orchid in the pot and carefully spread out the roots. Gently hold the plant by its stem and fill around the roots. Tap the pot to settle the potting mix–do not firm down.

  • Orchids may need anchoring in the pot with a stick or with wire

  • Re-pot just after flowering or during the period when new growth and new roots appear

  • Remove dead and shriveled roots but leave potting mix attached to healthy plump white roots. Do not worry if a few roots grow outside the pot—re-pot only when growth starts to suffer


  • During the growing and flowering season, feed your plants with Westland Orchid Feed diluted in rainwater
  • Feed every second watering in the active growing season (spring/summer) and every fourth watering in the winter


  • Orchid roots will rot easily if they are kept in wet conditions. It is therefore essential to water sparingly, ideally once a week.
  • Westland Orchid Water is a great option to feed and water orchid plants. Just 2 capfuls a week will help keep orchid plants healthy and flowering for longer
  • Orchids prefer high air humidity. Applying Westland Orchid Mist spray 1-2 times a week to the aerial roots and foliage will help replicate the plants natural growing environment

Tips for Better Results

  • Orchids need bright but filtered light so it’s best to avoid placing them in direct sunlight
  • Different species of orchid require different temperatures, so choose a suitable room in the house depending on the type of orchid you are growing
  • Most orchids require a rest period during winter when watering and feeding should be reduced


General Advice

  • Use in a well ventilated place and avoid breathing in dust
  • Always wear gloves when gardening and wash hands after use
  • Not suitable for Ericaceous (lime hating) plants
  • Store in a dry, frost free place away from weed killers and other garden chemicals
  • Reseal bag after use


Frequently Asked Questions

Q. Can I use this for my other houseplants?

A. We would recommend using a specific houseplant compost as other plants may not benefit from the free draining, open structure.

Q. When should I re-pot my orchids?

A. We would recommend checking the re-potting advice for type of orchid you have. Most will benefit from re-potting when the media has broken down or they have outgrown the pot, this is best done after flowering has stopped.
