1 86 WATER-LILIES 



Frequently a fungus attacks the leaves of 

 water-lilies, causing the leaf to become 

 spotted after which it finally decays. A fun- 

 gicide, such as a very weak Bordeaux mix- 

 ture, has been recommended to overcome this. 



There is quite another fungus that attacks 

 the young seedlings just after they have been 

 transplanted. Here again prevention is better 

 than cure. Strong and healthy seedlings 

 appear to withstand the fungus which seems 

 to be especially prevalent where manure has 

 been mixed with the soil. 



The snails which seem so greatly to enjoy 

 their existence in the greenhouse tanks set 

 aside for water-lilies are among the worst 

 pests during the earlier stages of growth. 

 Picking off by hand is perhaps the best remedy 

 though it will be found beneficial to keep a 

 few fish in the tanks. Not only do the fish 

 make war on the snails but they also destroy 

 a large number of the aphides which are 

 found in large numbers on the young plants. 

 Syringing the plants is probably the best 

 remedy.
