Orchids can be re-potted at any time of year except mid-summer when plants need their entire root system intact to grow well and mid-winter when most varieties are dormant, with the best time being when new growth is 5cm (2 inches) high and just before the new roots emerge. In most cases, this is early spring.

When re-potting allow the plant to dry out, remove from the old container (this will sometimes require cutting or breaking away the old pot,) removing all of the old potting mix so that the roots may be examined. Cut back decayed or over long roots and place in pot just large enough as these plants prefer to be ‘under-potted’ and water in. To avoid dehydration after re-potting spray the foliage rather than watering the pot. This will harden the root system.
