Hi all.
I divided rhubarb crowns last spring and gave them loads of dung. When the new stalks came they were water blisters all over them. didn't affect the taste but was wondering what could've caused it if it wasn't the really hot dry weather in july.

the problem you had with your rhubarb is caused by a shortage of water during a warm spell, but when the water runs out the water moves from the leaves back down to the roots through the stems (petioles). This problem can be caused indirectly by low organic matter in the soil eg a sandy soil. It can damage the rhubarb but makes it inedible and tough. You can prevent it in future by adding plenty humus or organic matter or add water before the problem occurs. It was thought at one time that this was caused by a virus. Dividing up the root when it gets too large can help to reduce the incidence of the problem. it only lasts for the one year or while the adverse conditions prevail.
