Care Instructions
Hornwort is relatively easy to care for. It thrives in moderate temperatures and can tolerate a range of light conditions, from low to medium light. It prefers high humidity and should be kept in water at all times. Regular pruning is recommended to control its rapid growth.Soil
As a free-floating aquatic plant, hornwort does not require soil. It absorbs nutrients directly from the water. Ensure the water is clean and well-oxygenated for optimal growth.Fertilizer
Hornwort benefits from a balanced aquatic plant fertilizer with an N-P-K ratio of 10-10-10. Fertilize monthly during the growing season to support its rapid growth.Repotting
Hornwort does not require repotting as it is a free-floating plant. However, it may need to be thinned out or divided if it becomes too dense.Propagation
Hornwort can be easily propagated by cutting. Simply cut a healthy stem and place it in water. The cuttings will quickly develop into new plants.Pruning
Regular pruning is necessary to control the growth of hornwort. Trim back the stems to prevent them from becoming too long and tangled. Pruning also encourages bushier growth.Toxicity
Hornwort is non-toxic to both pets and humans. It is safe to use in aquariums and ponds with fish and other aquatic animals.Additional
Hornwort is an excellent plant for beginners due to its low maintenance requirements and rapid growth. It also helps to improve water quality by absorbing excess nutrients and providing oxygen.REVOLUTIONIZE YOUR PLANT CARE
