Apply mulch annually to suppress weeds and conserve moisture. Organic material, such as sawdust and bark, contribute to soil structure. However, make sure to keep mulch away from plant stems. The first summer and autumn after planting are critical for young plants, so water thoroughly during dry periods. A light application (50g/m2) of general-purpose fertiliser in spring is beneficial. Sprinkle evenly and work into the top 2 to 3cm of the soil, taking care not to damage surface roots.
Tall plants and those in windy positions require staking to stabilize the root ball until established. Position the stakes in the hole before planting and place the plant between them.
Prune off any old flowers after flowering. Further pruning can be carried out after the danger of frost has passed. Cut old canes which have finished flowering or any that are crowded or damaged. Leave unpruned shoots which have not flowered, as these will flower next season. Only prune back by 1/3, as dichroa don’t require hard pruning like other plants, such as hydrangeas.
