Successfully Growing Rhubarb Plants

In both the Oregon Cascades and the Montana Rocky mountains, two plants that are among the first to start vigorously growing in the United States are strawberries and rhubarb. Both are extremely hardy perennials that seem to breeze right through even bitter cold temperatures. In fact, most of the rhubarb produced in the US comes from Oregon, Washington, Montana, Colorado and Michigan. It seems appropriate somehow that strawberries and rhubarb combine so well in strawberry-rhubarb pie. Rhubarb (Rheum rhabarbarum)┬áis quite easy to grow. That said, it should also be mentioned that rhubarb can’t survive anywhere that doesn’t get cold enough for the plant to become dormant. For the plant to do this, the daytime high temperatures in the winter need to be 40 F or less for at least several weeks. Most of the growth is also when the temperatures are below 70 F. Thus, it is a plant that is most at home in places that have a harsh winter and a cool spring. The rhubarb plant doesn’t do very well when the temperatures become very hot. In part, this is because the leaves are very large and when it is hot, they release a great amount of water in a process called transpiration. When the temperatures are such that more water is transpired than the amount taken in by the roots, the leaves begin to wilt. In fact, this is the cause of wilting leaves for virtually all plants and it is the reason squash and pumpkin leaves Continue Reading →
