Trees Heeled In 
This consists of removing them from bundles and tem¬ 
porarily covering their roots with soil, allowing the stems 
to slant away from the sun. If the plants have become 
very dry, it is advisable to lay them down and cover their 
full length with soil. Heeling-in is the best done on the 
north side of buildings. All broken or bruised roots should 
be removed, leaving a clean cut surface which quickly 
heals. The top should usually be cut back about one third. 
In poor soils, trees will make better growth if a supply of 
stable manure is mixed with the soil, put into the hole after 
the roots are covered. Manure should not come in contact 
with the roots. Large trees may be transplanted, but re¬ 
quire much care. A ball of earth should be taken up with 
them, if possible. It is better to root prune by digging a 
trench around each tree the previous year, cutting all the 
roots. This trench should be about one-sixth of the 
height of the tree from the trunk, i e., a tree 25 feet high 
would have a trench, four feet from the trunk, eight feet 
in diameter. Large trees should be set immediately after 
digging, and a stream of water should always be used to 
settle the soil about the roots. Street trees as maples and 
elms should not be set closer than 30 to 40 feet apart. 
Young trees well pruned and set, grow shapely with little 
additional care if unmolested. Crossing branches should 
be removed. If there is a tendency to become unsymetrical, 
the ends of the longest branches should be cut off. Shrubs 
should be planted in well tilled borders and trees do bet¬ 
ter when dug about and fertilized. Care should always 
be taken not to injure roots.
