Watering a Catalpa × erubescens 'Purpurea'
To maintain the health and vigor of Catalpa × erubescens 'Purpurea', it is essential to adhere to its moderate hydration needs. The plant thrives when watered deeply, allowing moisture to reach the roots, rather than frequent shallow applications, which can promote weak root growth. During dry spells, increase watering frequency to compensate for the lack of rainfall. However, it's crucial to avoid overwatering, as well-drained soil is vital for preventing waterlogged conditions that could impede growth. Regular monitoring of soil moisture levels will help establish an optimal watering routine for this striking shrub.
