Mock Orange in April: monthly care

Mock orange is best planted between October and November or in March and April, when the soil is workable and the shrub is dormant or just breaking dormancy. Choose a position in full sun or partial shade; flowering will be most abundant in sun, but the plant tolerates a few hours of shade without complaint. This adaptable shrub accepts a wide range of soil types—loam, clay, sand, or chalky ground—provided drainage is reasonable. Avoid waterlogged sites. Prepare the planting hole to roughly twice the width of the root ball and the same depth. Fork over the base to break up compacted soil, and mix a few handfuls of well-rotted compost or manure into the backfill to improve structure and give the roots a good start. Position the shrub so the top of the root ball sits level with the surrounding soil; planting too deep can lead to stem rot. Backfill carefully, firming the soil gently with your heel as you go to eliminate air pockets. Water thoroughly after planting—give it a full watering can or two—to settle the roots. Apply a 5–8 cm layer of mulch (garden compost, bark chips, or leaf mould) around the base, keeping it a few centimetres clear of the stems to prevent rot. If planting in spring, keep an eye on watering through the first summer, especially during dry spells. Autumn-planted specimens usually establish with less fuss thanks to winter rain. Space plants about 200 cm apart if you're planting a hedge or informal screen; mock orange grows vigorously and will fill the gap within a few seasons.

Mock orange is low-maintenance once established. Water regularly during the first growing season to help roots settle in, especially in dry weather. After that, the shrub is fairly drought-tolerant and only needs watering during prolonged dry spells in summer. A deep soak every couple of weeks is better than frequent shallow watering. Avoid overwatering; mock orange dislikes sitting in wet soil. Feed in March or April with a general-purpose granular fertiliser (such as Growmore or blood, fish and bone) scattered around the base at the rate recommended on the packet. Alternatively, apply a 5 cm layer of well-rotted compost or manure as a mulch in early spring; this feeds the soil gently and helps retain moisture through summer. Avoid high-nitrogen feeds, which promote leafy growth at the expense of flowers. Mock orange is fully hardy across temperate Europe (zone 4a–8b) and requires no winter protection. Mulch around the base in autumn helps suppress weeds and insulate roots, but isn't essential for survival. Pests are rarely a problem. Aphids occasionally cluster on soft new growth in spring; a strong jet of water or a spray of insecticidal soap usually deals with them. Diseases are uncommon, though powdery mildew can appear on leaves in hot, dry summers, especially if the plant is stressed or crowded. Improve air circulation by thinning congested growth during the July prune, and water at the base rather than overhead. Leaf spot may occur in wet seasons but is mostly cosmetic and doesn't require treatment.
