News has reached Plant Enthusiast Towers that staff at the RHS Garden at Wisley are partial to a little bit of tomato ketchup. Not on their chips but on their secateurs. The ketchup is, according to a member of the gardens team, excellent for removing the dried plant sap that stains secateurs and which can also spread viral diseases plant to plant. Just apply and leave for 24 hours, then wash off with soapy water.
If the level of sap build up on the blades has blunted the secateurs then this treatment can restore a good cut. But it does not of course sharpen blunt seacateurs.
We are off to give it a go, and will report back later.
