The Catalpa tree belongs to the Bignoniaceae family and includes several species, with the two most common being the Southern Catalpa (Catalpa bignonioides) and the Northern Catalpa (Catalpa speciosa). These deciduous trees are known for their large, heart-shaped leaves and showy clusters of tubular flowers. The flowers are often white with purple or yellow markings and appear in late spring to early summer.
Catalpa trees are native to North America and can be found in various regions, including the eastern and central parts of the United States.
- Soil: Catalpas prefer well-drained soil but are adaptable to various soil types.
- Sunlight: They thrive in full sun but can tolerate partial shade.
- Watering: Regular watering is essential, especially during dry periods. However, they are generally drought-tolerant once established.
Caring for Catalpa Trees:
- Pruning: Prune the tree in late winter or early spring to shape it and remove any dead or damaged branches.
- Mulching: Apply a layer of mulch around the base of the tree to retain moisture and suppress weeds.
- Fertilization: While catalpas are not heavy feeders, applying a balanced fertilizer in spring can encourage healthy growth. The TreeHelp Catalpa Fertilizer is designed specifically to address the nutrient needs of the Catalpa tree.
Common Diseases and Pests:
- Catalpa Sphinx Moth: The caterpillars of this moth can defoliate catalpa trees. Regular inspection and appropriate insecticides, such as BugBuster II can help control these pests.
- Verticillium Wilt: This fungal disease can affect catalpas, causing wilting and dieback. Ensure proper watering and promptly remove and destroy infected branches. Use a fertilizer with a lower level of Nitrogen such as the TreeHelp.com Therapeutic Fertilizer.
- Leaf Spot Diseases: Catalpas may be susceptible to various leaf spot diseases. Fungicides such as Liquid Copper or Monterey Complete Disease Control and good sanitation practices can help manage these issues.

Inside, discover a custom formulated specialized fertilizer, mycorrhizal fungal treatment, and a green-up Biostimulant. The mycorrhizal treatment functions akin to bacteria in the human digestive system, breaking down nutrients and moisture into a form readily metabolized by the tree.
Recognize the significance of regular watering. Opt for less frequent, yet prolonged waterings when hydrating trees. The objective is to wet the entire root zone to a depth of 24 to 36 inches, not merely the surface. Unlike brief rains that only normally penetrate 5 to 6 inches of soil, leaving lower roots dry, a systematic watering program proves instrumental in sustaining urban trees. Embrace this comprehensive approach to fortify the vitality and overall health of your Capalpa tree.
