Step by step: plant or sow sage

Sage thrives in full sun and well-drained soil, making it ideal for sunny borders, herb gardens, or large containers. It tolerates sandy, loamy, and chalky soils but will not survive in heavy, waterlogged ground. Before planting, work in some grit or horticultural sand if your soil is clay-heavy to improve drainage. A slightly alkaline to neutral pH suits sage well. Plant young sage plants in April, May, or September. Spring planting gives plants a full season to establish, while autumn planting works if your soil drains freely and winters are not excessively wet. Dig a hole slightly larger than the root ball, set the plant at the same depth it was growing in its pot, and firm the soil gently around the roots. Space plants 50 cm apart to allow for their mature spread of 40–80 cm and to ensure good air circulation, which helps prevent fungal problems. Water newly planted sage thoroughly to settle the soil, then water sparingly. Sage has low water needs and established plants tolerate drought well. Overwatering, especially in winter, is a common cause of failure. If planting in a container, use a loam-based compost mixed with extra grit and ensure the pot has drainage holes. Mulching is generally unnecessary and can trap moisture around the base, encouraging rot. In exposed gardens, a light mulch of gravel around the plant can help suppress weeds and reflect heat, which sage appreciates. Avoid rich, moisture-retentive soils or shaded positions, as these lead to leggy, weak growth and poor flavour.
