Types of horticultural grafting tape
- Parafilm / Polyolefin tape: Self-sealing, highly stretchable, breathable film that allows gas exchange while preventing moisture loss; degrades naturally under sunlight.
- Biodegradable grafting tape: UV-sensitive film that slowly photodegrades after graft take, eliminating the labor required to cut away tape and preventing bark girdling.
- Polyethylene (PE) budding strips: Elastic clear plastic strips offering high tensile strength for securing heavy woody rootstocks in mango and sapota wedge grafting.
- Waxed grafting tape: Cotton or synthetic fabric treated with beeswax and fungicides for field top-working on mature orchard limbs.
Proper binding technique for graft unions
Align the vascular cambium of the scion and rootstock precisely. Wrap the grafting tape firmly starting from below the cut and working upward in overlapping spiraled layers (like roof shingles) to prevent rainwater ingress. Finish with a self-adhesive stretch or gentle knot without crushing delicate cambial tissues.
Monitoring graft take and tape removal
Callus bridge formation typically completes within 4 to 8 weeks depending on ambient temperature and fruit species. For non-degradable PE tapes, inspect unions regularly and slit the tape vertically once buds sprout vigorously to avoid trunk constriction.

Common questions
Why is grafting tape necessary during plant grafting?
It holds the scion and rootstock firmly together, seals moisture inside the cut, and prevents fungal infection during healing.
What is the benefit of self-degrading grafting tape?
Self-degrading tape breaks down naturally under sunlight after callus formation, preventing bark girdling without manual removal.
How can nursery growers tell when a graft has taken?
The scion buds begin swelling and unrolling green leaves while the cambial union develops a healthy swollen callus seam.
