temperatures and, therefore, caii be used late in the fall and early in the 

 spring, vifhen it is too cold for paradichlorobenzene to be effective," Fall 

 applications of ethylene dichloride emulsion have been tried in the Experi- 

 ment Station peach orchard for three years. Very good control of borers was 

 obtained and no injury resulted when applications were made according to 

 Dr. Snapp's recommendations. Since severe injury has occurred in some states 

 and the rosipon for it is not known, this material is not being recomiTiended 

 for general use at any time of year. However, directions for its application 

 are available and vrill be sent to anyone wishing to use ethylene dichloride 

 emulsion experimentally at his ow n risk .

PLAITTIN G CULTIVATED BLUEBEIglES 



planting tine is fast approaching and blueberries like other fruits 

 are best transplanted in the spring, the earlier the better. -But first, where 

 shall they be put? The place to plant blueberries is largely determined by 

 the nature of the soil. If the soil isn't right, the bushes ivon't grov/. Lov/ 

 "frost pockets" are not good pj.aces. In such locations the bushes may be in- 

 jured by cold in winter or the crop nay be ruined by spring frosts. 



The cultJ.vated blueberry requires a moist, acid soil well supplied 

 with organic matter. Tlie amount of moisture in the soil is very important 

 because the blueberry will not thrive with either too much or too little. 

 Being a native of the sv/amp^ it will stand flooding during the dormant season 

 but its roots must be out of water during the summer^ Hcn.vever.. a soil that 

 is merely saturated with water but not flooded is very unsatisfactory. The 

 freezing and thawing of such a soil heaves the plants out of the ground, 

 breaks their roots and results in very poor grov/th. On the other hand, the 

 plants grow poorly and bear little in a dry soil. A soil that is constantly 

 moist but well enough drained to prevent "water logging" is the ideal. 



Most of the soils of New England are acid unless they have been 

 lined. 1/fliile these blueberries will grov; in extremely acid (pH 3.5) to fairly 

 acid soils (pH '0.6), they usually thrive best in soils classed as very acid 

 (pH 4.5 - 5.0). The presence of wild swamp blueberry, leather leaf, cranberry, 

 white cedar, or red maple indicates a good blueberry soil. 



V/hile most commercial blueberry plantings are on soils composed of 

 mixtures of sand and peaty material, such a combination is not necessary as 

 is shovm by the fact that so:ne plantings are grOT/ing well on sandy loaras, 

 loams, and even mediura clays. 



For a coLimercial planting the land should be ploived and harrov;ed 

 thoroughly before planting. If this can be done a year in advance and a cul- 

 tivated crop grovm, or the land fallowed for a year, there v;ill be less dan- 

 ger of grubs destroying the roots of the young plants. 



Those v;ho wish to grow a few plants in the backyard can remedy minor 

 soil deficiencies if they are v/illing to take the time and trouble. If the 

 soil has been limed, it is usually not acid enough for blueberries and is dif- 

 ficult to acidify. Otherv>rise, a bushel of acid horticultural peat, which
