Jasmine in April: monthly care

Jasmine (Jasminum officinale) thrives in full sun or partial shade, though flowering is most abundant in a sunny position sheltered from cold winds. Choose a site with well-drained loam or sandy soil; heavy clay should be improved with grit and organic matter before planting. The best planting times are March to May or September to October, avoiding waterlogged winter soil and summer drought stress. Dig a hole twice the width of the root ball and the same depth. Loosen the soil at the base and mix in a generous amount of well-rotted compost or manure. Position the plant so the top of the root ball sits level with the surrounding soil—planting too deep can lead to stem rot. Space plants 150 cm apart if you're planting more than one, or position a single specimen where it has room to spread 150–300 cm wide and climb 3–7 metres high. Backfill the hole, firming gently with your heel to eliminate air pockets, then water thoroughly. Jasmine is a vigorous twining climber and needs sturdy support from the outset: install trellis, wires, or a pergola before or immediately after planting. Tie in the main stems loosely with soft garden twine to guide growth in the right direction. Apply a 5–7 cm layer of mulch around the base, keeping it clear of the stem itself, to conserve moisture and suppress weeds. Water regularly for the first growing season until the roots are well established, especially during dry spells in spring and summer.

Jasmine has moderate water needs. Water regularly during the first year to establish a deep root system, then reduce frequency once settled. In summer, water deeply during prolonged dry spells—once or twice a week is usually sufficient if there's no rain. Avoid waterlogging, especially in winter, as jasmine dislikes sitting in saturated soil. Mulch helps retain moisture and keeps roots cool in hot weather. Feed in March and April as growth resumes. Apply a balanced general-purpose fertiliser (such as blood, fish and bone) or a slow-release granular feed around the base, following packet rates. Alternatively, use a liquid tomato feed every fortnight from late spring through summer to promote flowering. Avoid high-nitrogen feeds, which encourage leafy growth at the expense of blooms. Jasmine is hardy in zone 7a and above, but in colder gardens or exposed sites it may suffer frost damage to shoot tips in harsh winters. In zone 7, consider planting in a sheltered spot against a south- or west-facing wall. Mulch the root zone in late autumn for extra insulation. Top growth may die back in severe cold but usually regenerates from the base in spring. Common pests include aphids, which cluster on soft new growth in spring and summer—hose them off or use an insecticidal soap if necessary. Jasmine is generally disease-resistant, but poor drainage or overhead watering can encourage fungal issues such as powdery mildew. Ensure good air circulation through regular pruning and avoid wetting foliage late in the day.
