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.

Water to keep the soil moist

For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.

Without regular watering some plants never fully regain their beauty.

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.

Spring-Autumn · Planting

Trim dead flowers to prevent self-seeding

Note on self-seeding: If you do not want this plant to set seed it is necessary to promptly remove the spent flowers as they fade.

It's possible to carefully remove the seed heads, complete with seed, and then place them in areas where you would like new seedlings to grow.

Water some varieties differently

Some plants within this genus have additional requirements for water. It is best to look up your specific plant, or the species it belongs to for watering guidance.
