Is it essential to heat a pyramid in cold weather?
Many users winter geraniums and fuchsias using only a simple insulating cover made from bubble plastic. This is highly practical in areas where winter frosts are mild. In colder parts of the country some form of heating should always be considered, otherwise you could be “caught out” and lose valuable plants. Remember too, that heating is essential if you are to propagate early in the season, and running costs are so low that it’s nearly always worth having this option available.
