Floriculture industry, although with rapid growth and high profitability, is highly debatable regarding its sustainability due to the huge environmental impacts. Achieving sustainability requires joint efforts from all stakeholders which is, however, often neglected considering their economic-oriented thinking. Therefore, this review attempts to raise awareness and collective responsibility among the key practitioners in floriculture by discussing its sustainability in the context of soil health which is the foundation of agriculture system. Major challenges posed to soil health were identified from soil acidification and salinization by abusive use of fertilizers, to the poisoned soil biota by pesticide residues and plastic debris due to the excessive application of pesticides and disposal of plastics. The resulted continuous cropping obstacles were further elucidated by the concept of plant-soil feedback. Based on these challenges, we proposed several sustainable practices including breeding stress-resistant and nutrient-efficient cultivars, sustainable soil management, and recycle of plastics to overcome the decline in soil health. The problem of flower wastes was highlighted and efficient treatment by biochar synthesis was suggested. Nevertheless, we acknowledged the complexity of developing and implementing the proposed practices in floriculture as there is limited collaboration among research, practice communities, and policymakers. More attentions and efforts are urgently required in the soil studies in floriculture to expand the knowledges needed to solve the current soil threats and to bridge the understanding gap between researchers and stakeholders.
