Watering. Water regularly during the first year to establish roots, then reduce frequency as the plant matures and becomes drought tolerant. Avoid waterlogging the soil.
Fertilizing. Feed with a balanced, slow-release fertilizer in early spring to support healthy growth. Avoid over-fertilizing, which can cause excessive leafy growth at the expense of flowers.
This plant is tough and easy to care for. It grows quickly and tolerates dry conditions well. It needs regular watering when young but becomes drought-resistant as it matures. Prune lightly to maintain shape and remove any dead branches.
