From September to September- this the span Marion Dulles suggests, as September is a time for reorganization, and restarting. This is a practical , down to the growing benches type of how-to book, for beginning greenhouse gardener- and a good stimulant for those who have gone stale on routine. Any gardener worth his salt can learn from another good gardener. The Dulles' greenhouse is relatively small- a lean-to greenhouse, its purpose a decorative note from the house, a source of supply for cutting flowers, a reserve for transfer to the outdoor garden- and sheer joy (and its mead of work) for round the year gardening . Basic factors such as type of greenhouse (too cursorily handled, I felt), soil and its management, temperature, factors and control, equipment, selection of material and the round the year procedures comprise an excellent basic book for the average grower. There will be about 16 half tones. Appendices list plant material, etc.
