To conclude, the fact must be emphasised that 

 commercial horticulture is a highly specialised industry, 

 and practical experience in all departments is essential to 

 any measure of success. The principles which underlie 

 this and private gardening are identical, but the methods 

 are so entirely different that the best training in either 

 requires considerable modification to fit the practitioner for 

 the other. Some experience in both is an advantage, as 

 in private gardening the chief object is the highest 

 cultural results, but in market gardening the striving for 

 perfection is qualified and restricted by financial con- 

 siderations in every direction.
