Blueberries are acid loving plants. When you first plant them it is best to have at least a foot of soil and mulch mixed in the plant bed. Every year you add more pine bark mulch around each plant. This serves several purposes; 1) provides insulation to the roots from the hot summer sun and cold in winter, 2) retains moisture from rain and drip irrigation, and 3) helps maintain the correct ph balance in the soil.
We add the mulch by hand and and put two large scoops on each plant.
We get our mulch from Baily Bark in Nachodoches, TX. An 18 wheeler carries 110 cubic yards. The first challenge is to get the truck to back off our one lane county road into the berry patch. Javier keeps a close watch so the driver does not hit any water pipes or plants.
The truck has a live floor and the movement of strips causes the load to move forward and the entire truck to empty. It is pretty amazing to watch.
It will take a while, but in time this load will be under our blueberry plants. One reason we use this supplier is the product they sell is all bark and not filler. Some companies shred used pallets and waste wood and mix it into a load sole as pine bark mulch.
