Wooden Dahlia Greenhouse
Sunday, November 30th, 2008In wooden houses the polythene film can be easily attached to the glazing bars with drawing pins. Metal houses are more of a problem, but the spring type clothes’ pegs are quite good for clipping the material to the bars. In both types the film should be kept taut whilst securing it in position.
They should be stacked under cover until required for use. New pots must be soaked for a few hours before being used, as otherwise they will tend to dry out excessively quickly. All water used in greenhouse and frame should be free from infection. It is not really good to use rain water, particularly in industrial areas, as so often this has been allowed to stand in a filthy butt or tank for several days or even weeks before use, apart from containing possible harmful chemicals washed from roof and gutter.
Apart from their value as stand-bys, they have certain advantages in their own right, one being the small amount of storage space they take up, and another the perfect cuttings that are produced by them in the spring. Some varieties produce extremely thick shoots from ground roots, which are virtually impossible to strike, whereas the shoots produced by the miniature tubers are of ideal size and strike readily.
