During the planting process, spacing should be ample to accommodate the bushy spreading growth habit, allowing each specimen to flourish to its full potential, reaching up to 50 cm in height.

During extended periods without rain, increase watering frequency to compensate for the lack of natural precipitation. In contrast, during cooler, wetter spells, reduce the amount to prevent waterlogged soil.
