and others like them are used for this purpose. Saplings of these small trees can be 

 planted six inches apart from one another and cut to an inch above the ground. When 

 trimmed as closely as possible each year, they will accomplish the goal perfectly. Several 

 such groves can be seen at the Paris botanical garden. One, planted with small elms 

 fifteen years ago, densely covers a steep slope exposed to the broiling sun, where no lawn 

 could have survived. 



Saplings to be planted in nurseries need to be treated a bit differently from other 

 trees. Since they only need to stay there until they are strong enough to be permanently 

 transplanted, they are set in rows in patches or square beds according to the needs or type 

 of the tree. 



Saplings of large trees intended to form avenues, to border highways, to form 

 quincunxes, and to create groves, can be set in rows and spaced fifteen to thirty inches 

 apart, keeping in mind that they will have to stay in a nursery for a while, and especially 

 in a spot where they can be lifted without damaging the roots of other trees. 



Bushes and shrubs are also planted in rows, but in a bed about five feet wide 

 separated by paths fifteen inches wide. Depending on their strength and the time that the 

 saplings need to stay in the nursery, they are spaced in a line from six to fifteen inches 

 apart from one another. 



It's customary to cut off the taproots of seedlings to be placed in nurseries and to 

 trim their lateral roots. This practice poses no threat to their safety or to their taking root
