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.

Spring - early-mid · 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 pots or planted in the ground.

Planting

Divide some varieties differently

Some plant varieties within this genus have different requirements for dividing them when they get big. It is best to look up your specific plant, or the species it belongs to for guidance, and/or check the label.
