Growing Meadow sage in a pot

Salvia pratensis is a low-maintenance perennial once established. Water regularly during the first growing season to help roots settle in, but after that it has low water needs and tolerates dry spells well. In summer, water only during prolonged drought; overwatering or poorly drained soil encourages root rot and reduces flowering. In autumn and winter, natural rainfall is sufficient. Feed lightly in April or May with a general-purpose granular fertiliser or a handful of blood, fish, and bone scattered around the base of the plant. Avoid high-nitrogen feeds, which promote soft, leafy growth at the expense of flowers. Salvia pratensis grows naturally in lean meadow soils, so it doesn't need rich feeding; too much fertiliser can make plants leggy and prone to flopping. This salvia is fully hardy in zones 4–9 and requires no winter protection in temperate Europe. The crown may die back completely in cold winters, but it will reshoot reliably from the base in spring. A light gravel mulch around the crown in autumn helps keep it dry and reduces the risk of winter rot, especially on heavy soils. Pests are rarely a problem, but keep an eye out for aphids on young shoots in spring; a strong jet of water or an insecticidal soap will deal with them. Powdery mildew can appear on the foliage in late summer, particularly in crowded or shaded positions. Improve air circulation by thinning congested clumps and avoid overhead watering. Remove and bin affected leaves. Slugs occasionally nibble emerging shoots in spring; use organic pellets or barriers if damage is severe.
