Important: Safety Warning
This page recommends pest-control substances such as arsenic compounds, strychnine, or cyanide — in some cases applied to food crops. These substances are lethal to humans and animals, and their use is now banned or strictly controlled.
This page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.

Spraying Don'ts: Root
Root rot of violets and nematodes on the roots require soil treatment and sterilization.
Bulb spot of irises should be treated by soaking the bulbs for one hour in formalin solution, consisting of one ounce in two gallons of water. Root rot which is found usually only in the midst of an old matted clump is overcome by breaking the rhizomes from the clump, cutting off the decay, and planting in new soil with a watering of potassium permanganate, only enough to make the water of light pink colour.
MAINTENANCE OF VARIOUS KINDS OF GARDENS. No attempt should be made to develop a garden of any kind until a careful analysis has first been made concerning the probable cost for future maintenance. This applies equally as well to the extensive estate as it does to the detailed flower garden and to the average residence property. Plants are growing things and require constant attention in greater or less degree varying with types of development, whether of extreme formality or extreme informality, intended to produce certain effects. Many require an extremely abnormal quantity of labour and others require a minimum of labour for their average maintenance.
