Elder in March: monthly care

Elder is remarkably unfussy about position and will grow in full sun, partial shade, or even full shade, though flowering and fruiting are best in brighter spots. It tolerates a wide range of soils—loam, clay, sand, or chalk—provided drainage is reasonable. Avoid waterlogged ground, but elder copes well with damp conditions that would trouble many other shrubs. Plant bare-root or container-grown specimens between October and March, avoiding periods when the soil is frozen or waterlogged. The ideal window is October to December or February to March. Dig a hole twice the width of the root ball and roughly the same depth. Fork over the base to break up compaction, and mix a spadeful of well-rotted compost or manure into the backfill if your soil is poor, though elder establishes readily even without amendment. Set the plant so the top of the root ball sits level with the surrounding soil. Backfill, firming gently with your heel as you go to eliminate air pockets. Space plants 300 cm apart if you're planting a hedge or group; elder grows large and fast, reaching 3–7 metres in height and 2–5 metres across at maturity. Water thoroughly after planting—give each plant a full watering can—to settle the roots. Apply a 5–8 cm layer of mulch (garden compost, bark, or leaf mould) around the base, keeping it clear of the stem to prevent rot. No staking is usually necessary; elder establishes quickly and develops a sturdy, multi-stemmed framework. Water during dry spells in the first growing season until the roots have spread into the surrounding soil.

Once established, elder needs little attention. Water during prolonged dry spells in spring and summer, particularly if the shrub is in full sun or sandy soil, but avoid overwatering—elder tolerates moderate moisture and dislikes sitting in wet ground. In most years, rainfall will suffice. Feed in March or April with a general-purpose granular fertiliser such as blood, fish and bone or Growmore, scattered in a circle around the base at roughly 70 g per square metre, then lightly forked or watered in. A top-up of mulch (well-rotted compost or bark) in early spring helps retain moisture, suppress weeds, and gradually improves soil structure. Keep mulch a few centimetres clear of the stems. Elder is fully hardy across temperate Europe (zone 4a–8b) and requires no winter protection. It is deciduous and will drop its leaves in autumn. Pests are rarely a problem, though blackfly (aphids) can cluster on soft new growth in spring; a strong jet of water usually dislodges them, or tolerate them—they seldom cause lasting harm. Leaves may develop powdery mildew in dry summers, appearing as a white coating; this is unsightly but not serious. Improve air circulation by thinning congested stems during winter pruning. Both flowers and berries are edible and widely used for cordials, wine, and preserves, but always cook berries before eating—raw berries and all other parts of the plant (leaves, stems, roots, unripe fruit) are mildly toxic. Pick flowers in late spring and berries in late summer when fully ripe and dark purple-black.
