Using a watering can with a fine spray, I've just given a foliar feed to my
Tomatoes (In grow bags) and Potatotos (In tubs) and Rhubarb (In the ground)
Winding their wa btween the bags and the tubs are Nasturtiums - The Tomatoe/
potato / and rhubarb leaves all accept a damn good soaking but the
Nasturtiums repel every drop of water.

Does anyone know what natural waterproofing occurs on Nasturtium leaves?
