It’s a medium-sized tree, typically reaching 30 to 50 feet in height, with a broad, rounded crown.
Will Cladrastis Kentukea Tree Grow in Washington DC?
Washington DC, with its humid subtropical climate, is generally suitable for Cladrastis Kentukea. This tree thrives in USDA Hardiness Zones 4 to 8, and Washington DC, falls into Zone 7. The key to success in this region is ensuring the tree receives well-drained soil and full sun to partial shade. Yellowwood is relatively adaptable but prefers slightly acidic to neutral soil. With proper care, you should see this tree flourishing in the DC area.
How to Care for Cladrastis Kentukea?
Caring for Cladrastis Kentukea involves a few important steps:
- Sunlight: Plant it in a location that receives full sun to partial shade. It thrives best with at least 6 hours of direct sunlight daily.
- Soil: Ensure the soil is well-drained. Yellowwood doesn’t like soggy roots, so avoid areas with poor drainage.
- Watering: Water the tree regularly, especially during dry periods, to keep the soil moist but not waterlogged.
- Pruning: Prune the tree in late winter or early spring before new growth begins to maintain its shape and remove any dead or damaged branches.
- Fertilizing: Use a balanced fertilizer in early spring to promote healthy growth.
How to Propagate Cladrastis Kentukea?
Propagating Cladrastis Kentukea can be done through several methods:
- Seed: Collect seeds from mature trees in the fall. Stratify the seeds by placing them in a moist, cold environment for a few months before planting. Sow the seeds in spring in well-drained soil.
- Cuttings: Take softwood cuttings in late spring or early summer. Dip the cuttings in rooting hormone and plant them in a mix of perlite and peat moss. Keep the cuttings in a humid environment until roots develop.
What to Plant with Cladrastis Kentukea?
Cladrastis Kentukea pairs well with a variety of plants due to its striking appearance. Consider planting it alongside:

- Groundcovers: Creeping thyme or sweet woodruff can add texture and complement the tree’s roots.
Can You Grow Cladrastis Kentukea Indoors?
