cultivation until they develop a good root system and take 

 possession of the ground. Thorough surface tillage that will 

 maintain a dust mulch is the most desirable cultivation. 

 When it is impossible to give the trees such cultivation, as in 

 the case of seed spot planting, it is a good plan to mulch the 

 ground with straw to keep down the grass and weeds. In all 

 events keep the ground around the seedling trees free of weeds 

 and grass sod. 



After the walnut trees are five or six years old it is often 

 advisable to underplant them with such trees as the box elder, 

 green ash, or red cedar, so as to completely shade the ground. 

 Shading the ground and keeping out the weeds and grass are 

 factors vastly more important in tree culture than most people 

 are willing to believe. The walnut has very light foliage and 

 the grasses and weeds soon take the ground unless some other 

 trees with heavier foliage are planted with them.
