 In its natural home the Weymouth pine appears in pure 

 woods over consideralile areas, hut even more frequently is 

 found mixed with other species, especially hroad leaved trees. 

 It is well suited for pure woods, as it has a fairly dense crown, 

 maintains a sufficient leaf canopy until towards maturity, and 

 preserves a favourable layer of humus and moss on the ground. 

 In Europe it is grown chieiiy with Scotch pine, spruce, larch 

 and silver fir, when it generally holds its own. It is also well 

 suited for mixture with beech.

 High forest with clear cutting ; fairly suited for under- 

 planting oak on sandy soils, and also larch and Scotch pine ; 

 well suited for filling up blanks in young woods. It is less 

 suited for standards in coppice, or as nurses over and between 



tender species.

Planting is the rule, the seed being frequently too expensive 

 for direct sowings. The natural regeneration of the tree has 

 been found to be very slow in Europe. 



The seed ripens in September or October of the second year, 

 and falls almost immediately. It retains its germinating 

 power for 2 to 8 years. Of good seed 50 per cent, should be 

 fit to germinate. One pound of seed contains about 80,000 

 grains. The raising of plants in nurseries is similar to that 

 described for Scotch pine. As Weymouth pine plants are 

 more costly than those of Scotch pine, they are generally 

 treated with more care in transplanting, being as a rule placed 

 into pits about 4 feet apart.

Weymouth pine preserves tlie fertility of the soil. It requires 



protection against cattle and deer. Damage by insects is, 



according to present experience, not of much importance.
