  Apply an organic mulch

  Apply a 5-10cm layer of organic mulch around the plant in spring to reduce weeds, retain moisture and keep roots cool in summer. Leave a 10cm gap between the stem and the mulch to prevent stem rot. Before applying mulch, clear the area of weeds and water if it hasn't rained recently. Use biodegradable material such as garden compost, well-rotted manure, leaf mould or bark chippings as mulch.

  A mulch is a covering that can: protect the soil surface from rain, heat and cold; deter weeds; provide nutrients. Organic indicates that material has vegetative origin e.g. manure, compost. Synthetics i.e. plastics, or stones are often called mulches.

  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.
