Autumn · Planting
Divide when too large
The plant can be divided if it becomes too large, or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in a pot, or planted in the ground.
Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Planting & general
Outdoors
Water some varieties differently
Some plants within this species have additional requirements for water. It is best to look up your specific plant for watering guidance.
Planting
Prune lightly after flowering
After the plant has flowered, shorten all the stems that have flowered by cutting the shoots back to lower healthy buds.
