When to plant Lemon?

Lemon trees thrive in full sun and need a warm, sheltered position to perform well in temperate Europe. Because they are only hardy to zone 9a–11b, you'll almost certainly be growing your lemon in a large container rather than in open ground, allowing you to move it indoors over winter. Choose a pot at least 40–50 cm in diameter with excellent drainage holes. Use a loam-based compost such as John Innes No. 3, or a specialist citrus compost that offers good structure and drainage. Avoid peat-based mixes that stay too wet. If planting in open ground in a very mild, frost-free microclimate, prepare the site by digging in plenty of grit and organic matter to ensure the soil drains freely; lemons will not tolerate waterlogged roots. The best time to plant is March, April or May, once the risk of late frosts has passed and temperatures are reliably above 10 °C. If you're potting up a young plant, set it at the same depth it was growing in its nursery pot—never bury the graft union if your tree is grafted. Firm the compost gently and water thoroughly to settle the roots. Space container-grown lemons about 100 cm apart if you're grouping several on a patio, allowing air to circulate freely. After planting, water well and place the pot in the sunniest spot you have—ideally a south-facing wall or patio that radiates warmth. Avoid exposed positions; wind and cold draughts check growth and damage foliage. A layer of gravel or slate chippings on the compost surface helps retain moisture and keeps the root collar dry, reducing the risk of rot.
