What is needed, and what is necassary, to protect plants from the first frosts?
I have recently bought some so called 'fleeces', which are two layers thick. I am expecting the first frosts of the year to be coming soon, and am planning to cover up my display of begonias to hopefully prolong their flowering into the autumn. I have weighed them at the edges with some pebbles, secured with elastic bands, so hopefully they can drape over my vulnerable plants without risk of the wind blowing them off. But I know that I must relinquish them to the encroaching winter eventually. I am also busy planting bulbs into pots. These I line every year with two layers of bubble packing, and then place bark mulch on top. Last winter, whenever a harsh frost was expected, I also covered them over with white thermal curtain liner material. I am wondering what other people use to protect their pots of bulbs. What other approaches do you have? Do I go unnecessarily far to protect bulbs? (I live in Bracknell - it can sometimes get to minus 7). Would fleece be enough, and are my curtain liners not needed? They can be really very difficult for me to get into place because of my disability, and this is why I so need to know.
