Hybrid Catalpa (Catalpa x erubescens) is a beautiful flowering tree hybridized between Catalpa speciosa and Catalpa ovata. The Hybrid Catalpa is known for its unique and stunning flowers. The flowers are bell-shaped and a stunning mix of white, yellow, and purple. It also produces an abundance of large green seed pods. It typically is a smaller tree, reaching heights between 10 and 20 feet at maturity, and its thick foliage provides plentiful shade. It prefers to grow in USDA hardiness zone 5 to 8 and in full sunlight for best flowering. Hybrid Catalpa is a great choice for anyone who desires an attractive small tree for their landscape.

watering

Hybrid Catalpa (Catalpa x erubescens) should be watered thoroughly, about once a week, ensuring that all the soil is moistened. Water should be applied until water runs easily out of the drainage holes in the bottom of the pot. During the summer, it will likely need to be watered more often, as it can quickly dry out during hot, dry periods. In the winter months, watering should be less frequent (every few weeks). Make sure to check the soil occasionally for dryness, as overwatering can be just as damaging as underwatering.

sunlight

Hybrid Catalpa (Catalpa x erubescens) requires full sun or at least 6 to 8 hours of direct sunlight each day in order to thrive. This species of plant prefers to receive direct sunlight during the morning and afternoon, and ideally should be placed somewhere in the garden that receives direct sunlight between the hours of 9am and 4pm daily. Hybrid Catalpa also requires well-drained soil, so it should be placed in an area that is not prone to flooding or standing water.

pruning

Hybrid Catalpa (Catalpa x erubescens) should be pruned in late winter or early spring. Pruning should be moderate, cutting away only dead, damaged, or overly long branches. Leave enough foliage to maintain a full and symmetrical shape. Reducing the height by pruning from the top will ensure that the tree has increased branching lower down, creating fuller foliage coverage. Removal of up to 1-third of the branches is recommended. Each pruned branch should be removed as close to the branch where it originates as possible, without leaving a large stub.
