When pruning older Proteas that have been neglected, never remove more than 50% of the plant leaf area and ensure that the remaining cut stems have at least 15cm of healthy green leaves remaining. After pruning, each of the cut stems will produce 2 or 3 flowering stems for next season. As plants mature and the number of stems increase, the stem length often reduces. To produce longer stems, thin the bush by completely removing some stems, usually from the centre of the bush.
