|I planted blueberries about 3 years ago. They grew very little in the past years. A amend the soil to get more acid soil. I get a few berries but the plants themselves don't grow well. They are said to grow up to 4 -6 feet when mature. What am I doing wrong.|
|Let's start with the right cultivars for your growing region. These are proven to grow well in Wisconsin: Northblue, Northsky, North Country, St. Cloud, Polaris, Chippewa, Northland, Patriot and Bluet. Others are not as productive so check the names on your plants to make sure they are suitable for your growing region. If not, they may not thrive.
If yours are some of the recommended cultivars, you may want to dig and replant them. Open, porous soils such as sandy loams, loamy sands, and coarse sands with a high organic matter content will best provide the aeration the plants need. To improve the likelihood of successful establishment on most soils, add one and one-half to two cubic feet of peat per plant to the soil. Be sure to mix peat thoroughly with the soil.
Blueberry plants should not be allowed to develop fruit their first two years. You can prune away the flowers when they develop. Pruning will encourage new growth, which will provide additional places for new flowers and fruit to develop. If you dig and replant your blueberries (be sure to choose a sunny site), you can prune them back this year and expect them to flower and set fruit next year.
Hope this helps!!
