Conclusion

Commercial pothos production combines efficient propagation systems with rigorous disease management. The crop's fast growth and easy rooting make it ideal for volume production, but Rhizoctonia and Pythium require constant vigilance.

Stock plant management and cutting quality are the foundations of successful production. Invest in healthy mother plants and maintain strict sanitation throughout the production cycle.
