Dear Suffolk, you are correct. Blame those late-night gremlins.
Injecting weedkiller directly into the lower stem is the only way. I saw a council employee doing that self-same thing in Carmarthen on Wednesday.
Candy Crush is recommended for blight-resistance and good flavour.
Take three apples and a shoot to an Apple Day (held all over the country) if you aren't near Wisley.
I always cook mine in the microwave. Peel back the leaves, remove the silk and some of the leaves. Re-wrap. You can cook several at a time Very quick and doesn't involve pans of boiling water.
I'd stick with the bush shape. I assume the Gardeners World/Monty Don's budget is huge!
I water as necessary and feed once a week.
More than 1 apple is better. Plus a shoot with leaves.
NO, NO, NO. The so-called seed head is the male part of the sweelcorn. Remove it and you won't get any sweetcorn.
