Tex-R Propagation membrane from Texel Inc. is ideal for preventing root emergence underneath the growth medium of young nursery plants. The patented technology involves coating a high-quality, non-woven Tex-R membrane with SpinOut resin. This membrane can be used on sand beds, in pots, and under trays. Uncontrolled growth ceases as the root ends go into a dormant stage on contact with the membrane. Instead of roots growing outside of the container, the root system actually reinforces itself within its growth medium.
