the second year the plants will flower and  yield berries.  At the end of the year low bush blueberries produce fruit they will need to be mown to the ground. They re-grow from the roots the following spring, restarting the 2-year fruit production cycle.  (Vaccinium angustifolium) generally reach no more than 18-inches in height.  In cultivation they are propagated from shoots spread through underground runners, lowbush blueberries form low mats of plants that produce best on the afore mentioned two-year cycle. 

You don't have to mow them to the ground as they will still grow and produce some fruit.  Blueberries need soil that holds moisture but is also well-drained, humus-rich soil with good aeration.  One of the most important aspects of growing blueberry is the soil acidity. Plants need a pH of 4.0 to no more than 5.0 to really grow well. After testing your soil you can bring the pH down to lower levels with sulphur or 4 to 6 inches of acid peat mixed into the first 6 to 8 inches of topsoil.  I recommend also, enriching the soil with good organic compost.

The fall color of the blueberries is brilliant red with hints of orange making for a super display at the end of the season.
