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?

Is there a way to produce a sweeter crop of stalks by feeding specific compounds?

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?

Hi Judy, When I bought my rhubarb the man at the garden store had 2 types - one where the stalks turned red and one where they stayed green. Did you by a varity that goes red? Wendy
