Elms (Ulmus) - PictureThis

Elms

Evidence of elms indicates that these trees have existed for millions of years. Planted in the 18th and 19th centuries as street trees in the United States and Europe, many mature trees have gradually succumbed to Dutch Elm disease. Modern times have fortunately produced more resilient varieties. Valued for its beauty as well as its strength, the timber from elms has been used to make everything from wagon wheels to furniture.

Water: Adapted to temperate climates, elms requires moderate hydration, needing water once every 1-2 weeks. These trees thrive outdoors, tolerating short dry spells and aligning with seasonal rain patterns typical in their natural habitat.

Propagation: Propagation of elms involves seed sowing, cuttings, layering, or grafting. Optimal conditions include 20°C (68°F) temperature and well-draining, fertile soil. Cuttings should be taken from semi-hardwood branches, treated with rooting hormone, and kept moist. Disease prevention is critical, particularly against Dutch elm disease.
