Care Instructions
Tree dahlias require bright, direct sunlight and moderate temperatures to thrive. They prefer high humidity and should be watered regularly to keep the soil evenly moist. Protect the plant from frost and strong winds, as it can be sensitive to cold temperatures.Soil
Dahlia imperialis prefers well-draining loamy soil that is rich in organic matter. Ensure the soil remains moist but not waterlogged. Good drainage is essential to prevent root rot.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to promote healthy growth and flowering.Repotting
Repot the tree dahlia every 2-3 years or when it outgrows its container. Choose a larger pot with good drainage and fresh, nutrient-rich soil. Repotting is best done in early spring before the growing season begins.Propagation
Propagate Dahlia imperialis through stem cuttings or division. Take cuttings in late spring or early summer and root them in a well-draining soil mix. Division can be done in early spring by separating the tubers and planting them individually.Pruning
Prune the tree dahlia in late winter or early spring to remove dead or damaged stems and to shape the plant. Regular pruning helps maintain its size and encourages new growth.Toxicity
Dahlia imperialis is not known to be toxic to pets or humans. However, it is always best to keep plants out of reach of pets and children to avoid any potential issues.Additional
Tree dahlias can be susceptible to pests such as aphids and spider mites. Regularly inspect the plant and treat any infestations promptly. Mulching around the base of the plant can help retain moisture and suppress weeds.REVOLUTIONIZE YOUR PLANT CARE
