Heather – Erica carnea

Heather produces a profusion of attractive flowers in the winter that can add life to a patio or windowsill at an otherwise fairly colourless time of the year. The flowers grow so closely that sometimes the leaves are barely visible.

Heather is a hardy plant that stands up to outdoor conditions all year round. It flowers in the winter so it needs to be watered in the winter months. It must not, however, be watered when there is a frost as this will freeze the roots and destroy them.

Heather can be brought indoors in a tub or pot when it flowers but this is likely to shorten its life. If this is done, it should be kept cool at between 7° and 10°C (45°-50°F), to prolong the plant’s flowering period.Heather - Erica carnea

Heather (Erica cornea) is a shrub that grows to between 15-25cm (6— 10in). It has woody, branching stems with • short, pointed leaves 5— lOmm (½-2/5in) long. The dark pink flowers have rounded central sections and are 6mm (1/4in) long. They are borne on short stalks, of approximately equal length, along a central stem with the first-produced flowers at the bottom of the stem. There are many cultivars of Erica cornea available, some with foliage of a different colour and others which have differently coloured flowers.

Through The Year

March—May

In March and early April the last flowers are borne. In May cut back plants that have grown too large. Take off up to one third of the length of the stems.

June—August

During this time, Heather requires a rest. Water it so as to keep the compost in the tub or the window-box moist at all times.

September-November In September, propagate by taking tip cuttings 3-4cm (11/4-13/4in) long, and put 6-8 in a pot of rooting compost. Cover with a polythene bag and when rooting occurs, put in a tub or window-box containing soil-based compost.

December—February Heather should be in bloom. Water to keep compost just moist.

Pests And Diseases

The plant produces few stems and flowers if there is insufficient water or feeding.

Treatment: Water the plant and increase feeding. Do not forget that Heather needs water in the winter when it is flowering. Do not water the plant when the weather is frosty as the water will freeze in the compost and damage the roots.

Large Heather shrubs become bare in the centre when they are getting old. Treatment: Remove from tubs and divide, throwing away straggly sections. Re-plant smaller plants in tubs, or take cuttings.

Heather brought indoors loses flowers early when it is too warm. Treatment: Keep at 7°— 10°C (45°-50°F) to prolong flowering.

PLANT CARE

Heather is easy to care for providing it has the correct compost and proper light.

  • Potting: Erica cornea will tolerate a limy compost, unlike other types of heather. Use a soil-based compost.
  • Water generously in the summer, keeping the compost moist at all times. Water moderately in the winter, giving just enough to moisten the compost. Do not water when there is a frost.
  • Feeding: Feed occasionally during the flowering season with a dilute liquid fertilizer. Do not feed during the rest of the year.

BEST GROWTH ENVIRONMENT

  • Light: Heather will grow in bright sun and in partial shade. In shade it will not develop many flowers.
  • Temperature: Heather is a hardy plant that survives outside in a tub or window-box all year.

Buying Tips

  • The best time to buy Heather is in the spring or the summer so it can be planted in a tub or window-box before its winter flowering.
  • Look for a compact plant with robust stems and healthy looking, needle-like leaves.
  • Heather will survive outside in a window-box or tub for many years.

Grown for the pretty flowers it produces during late autumn and winter, Heather does best in a cool environment. It is best kept on a patio in a large tub.
