The use of seaweed in the production of ornamental plants

Ornamental plants play a crucial role in urban green spaces by enhancing aesthetic value and providing ecological and economic benefits. They help improve air quality, support biodiversity, and contribute to environmental purification. The horticultural industry benefits from cultivating ornamental plants, it faces challenges such as soil health and environmental pollution due to high-yielding cultivars and chemical fertilizers. To address these challenges, integrating sustainable practices, such as using seaweed as an organic fertilizer, can provide solutions. Seaweed, rich in essential nutrients and growth hormones, improves soil fertility, plant growth, and resilience against environmental stresses. Studies have shown its effectiveness in enhancing growth parameters, mitigating salinity stress, and increasing yield and quality in various ornamental plants. However, the response to seaweed varies across species and conditions. To optimize its use, tailored application rates, combined sustainable practices, and continuous monitoring are recommended. Further research is also needed to develop comprehensive guidelines for its application in ornamental plant production.
