Plagron Mega Worm 25L is a premium organic soil improver made from natural worm castings. Rich in slow-release nutrients, humic acids and beneficial microbes, it helps create healthier soil conditions that promote stronger plant growth and improved root development.
Worm castings naturally improve soil structure by increasing aeration, drainage and water retention within the growing medium. This creates a balanced root-zone environment where plants can absorb nutrients more efficiently and develop stronger root systems.
Mega Worm also contains naturally occurring enzymes such as chitinase, which help discourage insects while stimulating beneficial microbial activity in the soil. The presence of mycorrhizal fungi and trichoderma further enhances root health by increasing nutrient uptake and helping protect plants from harmful root pathogens.
Ideal for mixing into potting soil or garden beds, Plagron Mega Worm provides a natural way to improve soil fertility and boost plant performance.
