Can Lingonberry plants be grown from cuttings of another Lingonberry? If so, how? Any Tips?
According to Cornell University, lingonberries are frequently grown from cuttings: http://www.fruit.cornell.edu/berry/production/pdfs/Lingonberries.pdf
Take new growth cuttings in late summer and root them in moistened pots of 1:1 sand and peat mixture.
I read the article on growing lingonberries at home. Can you tell me where to purchase?
Check with your local garden centers and greenhouses.
Do a Google search for mail order sources.
Why won't my lingonberries set fruit? They bloom all summer but won't set fruit. I put in transplants 3 years ago.
You will want to have your soil tested. It is likely too high in pH for these plants to set fruit. This link will help you find the closest extension service to you: https://www.gardeningknowhow.com/extension-search
