Steri-Prune Pruning & Grafting Compound 250g – Bitumen Wound Seal Spray

Bituminous Seal for Pruning Cuts & Grafts

Steri-Prune is a bituminous pruning and grafting compound that dresses and seals fresh cuts and wounds on trees, shrubs and other plants. It comes in an easy-to-use 250g aerosol, so you spray it straight onto a cut to lay down a protective coating over the exposed wood. It's a long-standing Australian garden staple for tidying up after pruning, lopping and grafting.

What It's For

Use it after pruning or lopping to cover the cut, or when grafting to seal the join. The bituminous coating protects the exposed plant flesh and helps guard the wound against infection and unwanted regrowth while it heals over. It's suitable for all types of plants and trees that need pruning, and works on both shoots and roots.

How to Use

Make a clean pruning or grafting cut, then spray Steri-Prune directly onto the fresh, dry wound to form an even protective seal. The aerosol makes it quick to coat awkward angles and larger lopped limbs. Apply a light, even film rather than one thick coat. As a guide, a 250g can covers roughly 3 to 4 square metres depending on how thickly it's applied and the conditions on the day. Let it dry after application.

Safety & Handling

This is a petroleum-based aerosol, so keep it away from flames, sparks and heat, and use it in a well-ventilated area. Avoid breathing in the spray mist and keep it off your skin and eyes. Keep it out of reach of children, and store the can away from heat and direct sun. Always read the warning and safety directions on the can before use.
