BRING ON THE BERRIES eat and sticks them partway into the soil below his berry plants. Simply pulling the stick out of the ground reveals whether it’s time to give the plants a drink. Thirsty plants are easily detected by Popsicle sticks that are even in coloring and bone dry. Wait to water the ones that have a stick showing off a subtle shade difference or a touch of dampness. GROWING BLUEBERRIES IN CONTAINERS Dwarf varieties of blueberries can be a great choice for container gardens, although other types can also live and produce quite happily in pots. Look for drought-resistant berries like Bluecrop or those that best suit your climate. Northern Highbush Top Hat tends to do well in zones 3 through 7 while Southern Highbush Sunshine Blue thrives in zones 5 through 10. Cross-pollination between plants can boost overall plant fruiting and production, so plan to grow at least two if possible. Choosing the Right Container: When beginning with blueberries, choose a five- to 10-gallon container. This size provides plenty of room for blueberry bushes, which have root systems that tend to be shallow and wide-spreading. Planting the Berries: Blueberries prefer more acidic soil, so fill the container with acid-lovers potting mix or a 50-50 blend of potting soil and peat moss. Avoid mixes containing redwood sawdust as it is not recommended for blueberries. Test the soil pH throughout the growing season to ensure it falls into the optimal range of 5.0 to 5.5. If needed, you can amend the soil with fertilizers to gradually increase the acidity of the soil. “ LOOK FOR DROUGHTRESISTANT BERRIES LIKE BLUECROP OR THOSE THAT BEST SUIT YOUR CLIMATE.” 128 Maximum Yield USA  |  January 2017
