As for all Plectranthus, 'Blue Spires' are easy to grow and need little attention. Prepare the garden bed or potting mix by digging in compost or other humus material. Mulch after planting and water in well. In containers, a little extra care is needed to apply liquid or slow-release fertiliser twice a year, and to ensure that the root zone does not dry out completely. Pruning is best done in warmer months if needed but shaping with a light trim can be done at any time.
