Both last year and this year, my mother's Sweet Pea has a small fly inside in the middle each Sweet Pea flower, and she does't like giving small posies as gifts any more. What is the reason for these flies appearing and how should they be destroyed? Thanking you.
I have an Echium of about 1.20 metres in my garden which shall flower next year. How canI protect it from frost? It will only tolerate up to minus 3 Celsius as I read in one of my books. I heaped some earth around its base and popped a huge plastic bag over it as minus 5 are forecasted for tonight. Oh fright! Would a horticultural fleece do a better job or even bubble wrap?
A friend told me she wanted to tidy her garden and cut her lilies down as they looked very uglyafter flowering. Now she is worried that it might have been wrong and would damage the plants. As I have no lilies myself I could not answer her. The lilies are the ones with leafs directly on the flower stem.

I have had some good success this year with poppies and now have several withered stalks with seed heads. Should I collect the seeds and plant them or should I leave them to reseed naturally? If I should collect and plant, when should I do this?
