A good method for planting when soil is not sufficiently acid, is to 
dig a trench 3 ft. or Wider, 3 ft. deep, and long enough to hold the 
number of plants to be set. The trench is then filled with a mixture of 
one part sand, one part forest litter, one part weathered sawdust or acid 
peat or partly rotted oak leaves. The plants are set in the middle of a 
bed so formed, watered, mulched and watered again if soil becomes dry. 
The plants should be set slightly deeper than they grew in the nursery. 
The soil packed so firmly about the roots that the plant will resist a 
Strong tug without becoming loosened. If the plants are at all dry upon 
arrival they may be immersed in water a few hours before planting. Too 
much water around the roots of the plants during the growing season will 
tend to rot the root system, so care should be taken to keep the soil 
well aerated, cultivated and only moist during the summer. 
Blueberry plants respond readily to fertilization. Although nitrogen 
generally affects growth and yield most, it has been found that a complete 
fertilizer is more desirable, because nitrogen used alone causes 
excessive short growths. 
Young plants are easily hurt by too much fertilizer. None is needed 
the first year they are set. In the following spring (before plants are 
too leafed out) a small handful of fertilizer, well spread out around 
each plant, is beneficial. A fertilizer with an 8-8-8 analysis is recom- 
mended. Instances of injury to plants has been noticed where muriate of 
potash wag used in the analysis. Sulfate of potash is safer and better. 
Blueberry plants are as easy to grow, and require no more care or 
treatment than other bush plants. Under favorable soil conditions the 
blueberry plant will thrive and produce 4 most delectable fruit, and 
provide beauty in its setting the year around,
