How to pot and re-pot?

Repot any time of the year; spring is an ideal time during the growing season.

  1. The first step is to find a new pot, choose one with just enough room for the roots and fill one third of pot with potting mix.
  2. Remove dead and shrivelled roots but leave potting mix attached to healthy plump white roots.
  3. 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.
  4. Top tips – 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.

How do i keep my orchids looking great?

Don’t let them go hungry

  • Packed full of all the essential nutrients your orchids need to thrive, feeding with Westland Orchid Feed is the secret to lush, healthy orchids!
  • Feed every second watering in the active growing season (spring/summer) and every fourth watering in the winter

Are they thirsty?

Don’t let your plants get stressed! Under or over watering your plants can often lead to pest and disease problems.

Top tip – use a Westland Houseplant Watering Indicator so you know exactly when to water, they change colour when your plant needs a drink.

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

Tips for Better Results

  • 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
  • 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

  • Don’t use me with ericaceous plants
  • Before use, rework potting mix between hands to reconstitute
  • Use in a well ventilated place and avoid breathing in dust
  • Wearing gloves is a good idea, and don’t forget to wash your hands afterwards!
  • 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.
