Step by step: plant grape
Grapevines thrive in full sun and need a warm, sheltered position—ideally against a south- or southwest-facing wall or fence where they can benefit from reflected heat. They tolerate a wide range of soils, including loam, chalky, and sandy types, but drainage is critical; waterlogged roots will quickly rot. Before planting, dig in plenty of well-rotted compost or manure to improve soil structure, and on heavy clay consider raising the planting area slightly or incorporating grit to aid drainage. Plant bare-root vines in March, April, October, or November, and container-grown plants any time during the same windows, though autumn planting allows roots to establish before spring growth. Dig a hole roughly twice the width of the root ball and deep enough so the graft union (the swollen knobbly bit near the base of the stem) sits just above soil level. Space vines 150 cm apart if planting more than one. Spread the roots out gently, backfill with soil mixed with compost, and firm in well to eliminate air pockets. Water thoroughly after planting, even in autumn, to settle the soil around the roots. Apply a 5–8 cm layer of well-rotted manure or compost as mulch around the base, keeping it clear of the stem itself to prevent rot. Install sturdy support immediately—horizontal wires fixed to a wall or fence at 30–40 cm intervals up to at least 2 metres high—because grapevines are vigorous climbers and will need tying in from the first growing season. Stake the main stem loosely to guide it upward until it reaches the wire framework.
