Dawnsaunt's Garden
Grape - White
Species: Grape - White.
Dr Bob says, it is a good idea, often vents are in the wrong place. There are loover types, but automatic vents which work on heat i.e. if it's very hot they open and when it's cold they close. Better in the roof though. Fan heaters can be set to blow cool air. But most important all the year round is to keep everything clean, nothing that's not needed i.e. flower pots, wellies etc. should be left in your greenhouse. Brush the dormant rods on your vine with a weak solution of Armillatox.
