Northern Highbush blueberry #304883

Asked March 04, 2016, 11:44 PM EST

I am in southern MN 55959 zone 4. I was told to bury some large containers in my garden to make soil amending easier for the health of some new Northern high bush blueberry plant this spring. In learning more as I'm deciding on varieties, the company I plan to order from said this will be ok for only about 5-6 years. The roots don't go deep but do spread wide! Am I safest to dig those containers out now before planting those new plant? I'm ordering 4 year old plants to start! Your opinion would be greatly appreciated! Thank you. Blessings, Debbie

Expert Response

Yes, when the weather warms, remove those containers. We recommend that you add peat moss to the native soil to make it acidic for blueberries. However, before you do that, it would be best to have your soil tested and see if and/or how much would be needed. Here is a link to our soil testing lab:  It have the information you need to submit a sample. Here also is a link to our publication on growing blueberries:
