For this reason, most mixes have limited effective life - usually only 2 to 3 years. Washing mixes, removing the dust and fine material can assist in prolonging its life. Bark mixes should be soaked for some days to wet it completely before use, then allowed to drain as a wet mix cannot flow around the roots during repotting. Repotting usually is completed just after flowering. The ideal time is just as new root activity commences in the spring after the usual winter dormancy or period of reduced activity.
New growth is indicated by the green tips to the roots.
The aim is to get the plant re-established as fast as possible, so a strong growth is initiated and reached maximum size at maturity to ensure maximum flowering next year. After repotting, plants should be kept more shaded and somewhat dryer than usual. Misting the foliage only for 2 to 3 weeks may be all that is required. Normal watering can be commenced once root activity is evident. Do not forget to re-labe l all repotted plants, and divisions with their correct name and date of repotting.
