I have a 2 yr old rhubarb that has produced very well over the last 18 months. yesterday I came home from work and it was limp (never seen it do that before) we have had about 15ml of rain over the last 2 day, and it is quite humid. I gave it water, as the soil looked dry. It seemed to pick up. This morning it is worse all leaves & stems drooping. I dug around the plant and the soil is moist, there seems to be no grubs and there are earth worms in the soil. As this is not it's first hot season, i am at a loss as to what is causing it and what I can do

My Rhubarb grows well but the stalks arent very thick. Is it a different type that I need to buy? Thanks Roma

I have 2 types of rhubarb, both of which are supposed to be red, but the stalks remain green. Is there something lacking in my clay soil?

Hi, I am concerned that my rhubarb is very prolific (leaves and stalks) however it has not turned red - it remains green. The name on it is "rhubarb - tasmanian grown". Looking forward to hearing from someone. Thx....Lesley

Rhubarb will grow all the year round? ex farmworker from the early 50s in UK. Would like someone to put me in touch with Jerrod Nichols or Rod Harker of Tasmania, Rhubarb growers.

Hi Lesley, It is probably a green rhubarb, I have one and it is lovely to eat but doesn't turn red. If you prefer red rhubarb you need to purchase a red rhubarb comb. Cheers, Stewart.

I planted several rhubarb crowns a few months ago and they have grown rapidly. They are still mostly green although the base of the stems are red but they are very high. When should I harvest them?

I planted rhubarb in mid june, but the stems have all died off. Will it sprout again in autumn/summer?

Where can you buy rhubarb?

If you can plant them either in big pots or in dappled sun/part shade it may be helpful but I don't think shade cloth would help as much as drip irrigation may. Best of luck!
