I have planted rhubarb roots in the San Joaquin valley and find the root
crowns rot below the surface.
The old-fashioned summer rhubarb usually goes off that way in very hot
localities. If there is too much alkali or hardpan, or if planted too
late, the same results will be had with any sort of rhubarb. Where it is
very hot, plants, irrigated in the morning near the plants, scald at the
crown and die in a few days. If irrigated in the afternoon and the
ground worked before it gets hot the next day fine results are obtained.
The winter rhubarb varieties do well in hot districts if the roots are
planted from September 15 to May 1, while in cooler sections, April,
May, June and July are the best months and will insure a crop the
