The variety of yr rhubarb will dictate that. Some produce stems that remain green in colour ie do not turn red. Check your variety for its characteristics.

i have 4 plants they were planted [crowns]in september one has withered up one is starting to wither one is reasonable and the other is going from strength to strength they were all planted at the same time about 1 meter apart in the same bed our soil is quite sandy with plenty of organic fertilizer and is well mulched it is watered only with rain water from tanks.what am i doing wrong.

I bought 2 rhubarb plants they were doing very well for a couple of months. Then 1 wilted and died A couple of weeks ago, now the other one is starting to do the same thing. Should I give it some chook pellets? I would hate this one to die. I love rhubarb. It is in a raised garden.

Do i need to cover the crown or leave it exposed? My rhubarb is looking very wimpy, floppy stalks etc. It's in a big pot, could I be overwatering it?

My rhubarb has been in for a few months now and it is growing very well. It looks so healthy so why can't I pick it and cook. Why do I have to leave it for a year before I harvest?

After you have harvested the rhubarb do you cut it to ground level and leave to regrow - and, if you fertilise, what do you use? many thanks.

NO, you pull the stalks away from the plant. New stalks will grow from between the existing stalks. I fertilise with compost and blood and bone and my plants do very well

I've got 2 rhubarb plants, possibly about 10 years old - beautiful huge glossy leaves but the stalks are only about 4" long. I've heard that rhubarb is a big feeder so they've got plenty of well rotted horse manure but it only seems to be feeding the leaves ! Help ......

How long do I leave the stalks before I pick and cook them? I've been waiting ages for the to turn the beautiful red colour but they are still green with red tinge! It is only a young plant, does that make a difference?

This morning I found all the stema of one plant limp and lying on the soil and the leaves, were discoloured and looking sick. I have 2 other crowns in the same area and despite applying liquid fertilisers and solid manures they have not produced any significant growth. There is a fig tree about 2 metre away.
