Manchurian lilac

Manchurian lilacs should be watered regularly during the growing season, which is typically from April to September. Watering 1 to 2 times a week is usually sufficient; however, during periods of extreme heat or dryness, additional watering may be necessary. Make sure to check the soil for dryness before watering and adjust your watering schedule as necessary. Keep the soil moist but take care not to overwater, which can cause the plant to become waterlogged. If rainfall is adequate, then supplemental watering may not be necessary. Windy conditions can cause the soil to dry out quickly, so make sure to check the soil often and adjust your watering schedule accordingly.

Manchurian lilac (Syringa pubescens subsp. patula 'Miss Kim') thrives in full sun. For best growth, it should receive 6-8 hours of direct sunlight each day during the summer growing season. Morning sunlight is usually preferred due to the increased intensity in the morning, followed by a decrease in the late afternoon. In high summer temperatures, the plant may benefit from some afternoon shade to protect it from the intense heat. During the winter months, this deciduous plant should receive at least 4-6 hours of direct sunlight.

The Manchurian lilac should be pruned in early spring before new growth appears. Pruning helps control the height and width of the plant, as well as improve overall shape and structure. Dead or declining branches should be removed each year. To keep the shape of the shrub balanced, it is best to prune out small branches here and there rather than cutting large areas. Cutting out older branches helps to thicken the plant and promote flowering. As a rule, most lilacs should be pruned to no more than 1-third of its total height. The Manchurian lilac can be pruned more severely.
