Oregano, also called wild marjoram, is a low, spreading hardy perennial for hot, dry places. Its aromatic leaves bring depth to Italian and Greek dishes, tomato sauces and pizza. Golden and compact varieties are particularly useful in pots, edging and small herb gardens.

When and how to sow

Set out a plant or division in April or May, after the worst frosts, in a sunny site with free-draining soil. In cooler northern gardens, wait until May or protect young plants with fleece. Seeds can be sown in spring in trays or directly into prepared soil. Leave room for the clumps to spread, or contain them in wide pots. Golden forms appreciate some shelter from harsh winter wet.

Care

Water plants while they establish, then only in prolonged dry weather. Oregano performs best in lean soil, so avoid heavy feeding. Trim stems after flowering to keep the clump compact and encourage fresh leaves. Divide congested plants in spring. A gravel mulch helps keep the crown dry and suppresses weeds without trapping moisture.

Common problems

Poor drainage and winter wet cause most losses, especially on clay ground. Raise the planting area or use a container if water lingers. Mildew and leaf spotting are more likely in crowded, shaded growth. Cut back congested stems, remove marked leaves and water around the base early in the day.

Harvest

Snip leafy stems from late spring onwards, preferably before flower buds open, when flavour is fullest in warm, sunny summers. Take a few sprigs at a time for cooking, or cut larger batches on a dry morning. Dry stems in an airy room and store the leaves sealed for winter use.
