Gardening Questions And Answers
What to Do for a Cranberry Not Fruiting. A cranberry vine with no fruit might need better pollination. If your plants are producing flowers but little fruit, you may need to attract more pollinators to your garden. Nitrogen fertilizer will encourage cranberries to produce runners at the expense of upright growth.
What causes Yellow Vine? The YV symptoms are most likely due to nutritional imbalances in the cranberry plants [potassium and magnesium in particular]. But fertilizer management is not the cause of the problem. Instead, we believe that the nutrient imbalance is secondary to root problems caused by stress.
Fertilize every three to four weeks with slow release fertilizer and follow up regularly with a balanced liquid fertilizer.. Hand weed as needed. Protect cranberry vines from damage during winter conditions with a thick layer of mulch such as pine boughs. Snow accumulation may become a protector of sorts as well.
The Cranberry (genus Vaccinium) is native to the swamps and bogs of northeastern North America. It belongs to the Heath, or Heather family (Ericaceae), which is a very widespread family of about 125 genera and about 3500 species! Members of the family occur from polar regions to the tropics in both hemispheres.
According to the published guidelines, the lowest safe temperature that cranberries can withstand is 23°F. In order to protect the fruit from frost damage, growers run their irrigation system, coating the fruit with a blanket of water. Water protects the plants through the law of physics known as the Heat of Fusion.
Many people consider cranberries to be a superfood due to their high nutrient and antioxidant content. In fact, research has linked the nutrients in cranberries to a lower risk of urinary tract infection (UTI), the prevention of certain types of cancer, improved immune function, and decreased blood pressure.
