The gardener who imagines that his work can be reduced to a set of rules and formulae, followed and applied according to special days marked on the calendar, is but preparing himself for a double disappointment. Few things are so certain to be uncertain as the seasons and the weather; and these, rather than a set of dates, even for a single locality, form the signs which the real gardener follows. That is the great trouble with much book and magazine gardening.
