How to take care of rhubarb plants?

Rhubarb grows best in full sun, but will tolerate partial sun. Choose a site with soil that is well-draining and fertile. Good drainage is essential, as rhubarb will rot if kept too wet. Mix compost, rotted manure, or anything high in organic matter into the soil.

Adding to that, when should you not pick rhubarb?

It is generally recommended that home gardeners stop harvesting rhubarb in early to mid-June. Continued harvest through the summer months would weaken the plants and reduce the yield and quality of next year's crop. The rhubarb stalks may become somewhat woody by mid-summer, but they don't become poisonous.

With this in view should I cut back my rhubarb?

Prune back the rhubarb stalks to the ground in late fall or early winter after they begin to die back naturally from frost. Rhubarb may not die back completely if temperatures remain above 40 degrees Fahrenheit, but dead and damaged leaves can still be removed throughout winter, cutting them with shears or a knife.

Subsequently, question is, how do you increase rhubarb growth?
