western catalpa

Western catalpa should be watered once a week or more frequently when planted in a container. It is important to ensure the soil around the tree stays moist but not waterlogged. When watering, soak the soil once or twice at the base of the tree to encourage deep rooting. Aim to provide a total of 2-3 inches of water each week, increasing the amount during periods of hot, dry weather.

Catalpa speciosa, the western catalpa, is a fast-growing small to medium-sized deciduous tree native to the Western United States, with a wide, spreading canopy and an open, airy crown. Western catalpa thrives in full sun and requires at least 6 hours of direct sunlight per day to reach its maximum growth potential; however, it can tolerate partial shade. The tree's leaves have a silvery underside, which helps reduce water loss and conserve energy. Western catalpa prefers areas with hot summers, with an average temperature of at least 65°F (18°C). The tree is drought-tolerant, though it does best with regular waterings during dry spells. The best time to water it is early in the morning or evening when the sun is not directly overhead. Because the tree does not tolerate wet soils, well-draining soils are recommended.

Pruning western catalpa (Catalpa speciosa) should occur in early spring, shortly after frost but before buds and leaves appear. Pruning should be done selectively, removing spent flower clusters or dead branches, as well as any branches that cross or rub against each other. Heavy pruning should be limited, as western catalpa is a fast-growing species and will recover quickly. Pruning during the growing season should be focused solely on dead or damaged branches, as heavy pruning afterwards can damage blooming and growth.
