Thank you Fractal, Ian digs v2 and Noseypotter for your suggestions. All v useful ideas -- and I shall try them all! Truly I never expected to get this kind of help -- and so quickly. I'd originally Googled Gardeners' Question Time and found Grows On You instead (and you know what a lottery GQT can be re getting a reply). Robertam
