198 THE SPIRIT OF THE SOIL 



Don't attempt to grow plants out of their season 

 in the open. 



Don't attempt to grow plants in sour soil. Lime 

 must be given in this case to render the soil neutral 

 or slightly alkaline. 



Don't give too much water. Pot plants do not 

 require watering until the pots ring when struck. 



Don't judge the water condition of the soil by the 

 surface. 



Don't overcrowd the plants, but leave room for root 

 growth. 



Don't use humogen in greater concentration than 

 i part in 10, or you will waste the material. 



Don't be disappointed if a slight retardation is 

 evident at first when using sterilized soil. 



Don't leave bags of humogen where they can get 

 wet. An ordinary dry garden shed is a suitable 

 place. 



Don't be afraid that the humogen can injure plant 

 growth. 



Don't be afraid of the bacteria in humogen. They 

 are perfectly harmless. 



Don't attempt to grow plants in rooms with coal 

 fires or gas. 



POINTS TO BE REMEMBERED. 



One part of humogen to ten of soil gives the best 

 results, with the exception of bulbs (monocotyle- 

 dons), when i in 20 should be used. 



Mix up your compost in accordance with the 

 requirements of the varying species, using humogen 

 instead of leaf mould and dung.
