Protea 'Susara' · Protea 'Susara'
Under glass grow in a mix of 1 part loam with added charcoal and 3 parts equal measures of grit (or perlite) and peat substitute, in full light. Water moderately in spring and summer. Apply a liquid fertiliser of magnesium sulphate and urea, both at half recommended strength, once in spring and again in early autumn. Water sparingly in winter. Outdoors grow in poor, well-drained soil in full sun
Little pruning is needed. Remove diseased, damaged, crowded or crossing shoots and unwanted growth. Timing depends on the plant: generally late winter or early spring; plants prone to bleeding and deciduous magnolias need different timing, and deciduous azaleas and lilacs are pruned after flowering.
