Talkback: Potato blight and Bordeaux Mixture
in Talkback
I've used Bordeaux mixture but not Dithane simply because GO reluctantly recommend it as the fungicide of last resort. I'm never happy about using it though.
I've also tried Sarpo Mira and Axona varieties - they're phenomenonly resistant to blight, but I've found their taste is nothing to write home about. I'm trying some of the other Sarpo varieties this year to see if at last there might be that happy combination of resistance and taste.
I also grow lost of earlies to get round the problem. Of course most of these don't store for as long as maincrop, but I've found that Harlequin does seem to be better than most. And it tastes wonderful

My friend in Ireland says the Sarpo varieties still succumbed to blight. Agree there are other potatoes I like more flavour-wise.
You all helped me last year with my raspberries for which I am extremely gratefull - they turned out to be lovely yum!
Again Nettle tea is helpful, and companion plant like Archangel (white deadnettle) growing close by. Foxgolves growing near also strengthen other plants, but some plants adversely affect potatoes growing near them, especially fruit trees.
Potatoes with stinging nettles growing among them seem to resist blight - if you can bring yourself to actually plant your potatoes in a nettle bed!
Big Arch: buy some new dahlias!
I lost some too this year. In previous years I didn't protect them and was lulled into a false sense of security, last winter was just too harsh. You'll still find some dahlias at garden centres now, you can plant them directly into the ground when you get them.
