94 THE COMPLETE GARDEN 



The following plants, if attacked by leaf spots or mildews, may be 

 saved by fungicides (See Page 77) : 



Alyssum (mildew). 



Anemone (root decay and rust). Destroy affected roots. 



Aquilegia (mildew and black spot). 



Campanula (red and brown rust). Keep away from pinus rigida. 



Chrysanthemum (leaf spot or powdery mildew). If rusted, plants should be 



destroyed. 



Convallaria (stem rot). Burn affected plants. 

 Coreopsis (mildew). 



Delphinium (black spot on leaves). Remove and burn. 

 Ferns (tip blight). 



Hollyhock (leaf spot). If attacked by rust or anthracnose destroy the plants. 

 Iberis (club root). Use lime in soil. 

 Papaver (mildew). 



Peony (stem rot, leaf spot, botyrides). 

 Phlox (leaf spot and powdery mildew, and stem canker). 

 Sedum (leaf spot). 

 Thalictrum (red spot). 

 Veronica (leaf disease), (leaf spot). 

 Violets (leaf spot and leaf blight). 



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.
