How do I help my Rhubarb come in better?

Question:My rhubarb patch has gotten wimpier the last couple of years. How can I help it grow bigger? I live in Minnesota, USA. Zone 4, I think.

Answers:
Rhubarb are hungry plants. "Stalks that have become woody or porous are no longer good. To prolong your harvest (10-12 weeks) keep the stalks harvested, the seed stalks pulled out and the plants watered and side-dressed with fertilizer. Always leave several stalks to ensure that the plant will keep producing. Stop harvesting when the plant begins to produce thin stalks. It is a sign that the plants energy level is running low and it needs a rest."
"Liberal quantities of fertilizer are needed.
"Rhubarb responds well to fertilizers. The quality of the crop harvested depends to a large extent on the care and fertilization received."

"Home gardeners should give each plant 1 cup of 10-10-10 fertilizer each spring, applied in a circle around the plant when growth starts. Fertilize each year and cultivate shallowly as often as necessary to remove weeds.
"Manure is an extremely valuable source of organic matter as it helps to conserve moisture, preserves the soil structure, and makes nutrients readily available."
