Infected roots no longer function properly , causing a reduction in water and nutrient absorption . A mature gooseberry or currant shrub can produce up to four quarts of fruit annually . Test your soil for pH and nutrient needs ; professional soil testing may be done through your county extension office . This disease , caused by bacteria present in the soil , infects plants through wounds or natural openings near the root crown of the plant . Process pints or quarts for 25 minutes in a boiling water bath . This will keep voles from burrowing under them to get at the trees . Like a plastic tree guard , it should be pushed into the soil to prevent entry of voles . These exclude voles ( “ meadow mice ” ) and rabbits , preventing them from feeding on the bark .
