We have had good results using horse manure on rhubarb.

Our plants were from an earlier patch that was at least 50 years old. We have had them for about 3 years and are harvesting them almost all year. They slow down a bit in winter but we still get feeds off them then. They now get tons of manure and pellets with mulch over the coldest part of the year and they are grown in a substantial raised bed with frequent watering (not sure the watering is required as frequently but we do it when the leaves wilt a bit). The raised garden is still settling so I am hoping the watering can slow down a bit as the soil compacts and retains more of the water.
