Weigela 'Black Magic' should be watered when the top inch of the soil is dry. Depending on your local climate, this could mean watering the plant anywhere from once every few days to once every couple of weeks. Before watering, make sure to examine the soil to ensure that it isn't overly saturated. When watering, be sure to thoroughly saturate the root system. It is best to water in the morning or evening when temperatures are cooler, as this prevents the water from evaporating too quickly. When using a sprinkler, keep it away from the leaves and petals of the plant to prevent fungal or bacterial infections.

Weigela ‘Black Magic’ does best in full sun, which is defined as 4 to 6 hours per day of direct sunlight. If the plant is receiving less than 4 hours of sun a day, it will struggle to bloom. Too much direct sunlight can lead to leaves becoming scorched, so in hotter climates, it’s best to provide some afternoon shade. During the shorter days of the winter months, some afternoon shade may help to encourage longer bloom times.

Weigela 'Black Magic' requires at least annual pruning for the healthiest growth. Pruning should be done in late winter, before new growth begins in spring. Remove dead, diseased, or damaged branches first and then trim back any straggly branches. Do no over-prune, as this can reduce flowering. After the initial shaping of the shrub, prune selectively to maintain a pleasing shape. Prune branches that grew during the previous season down to individual buds just above an outward-facing bud. This will encourage full and bushy growth of the shrub. Finally, if needed use broad-leaf pruners to remove branches that are too close together, to encourage better air circulation and light penetration.
