Rhubarb can be very variable. I have seen both short and long stemmed rhubarb in the shops. I have also seen some with mostly green stems and some that are deep red for their full length. As most rhubarb is grown from seed, and there are also a number of different varieties, this variation is inevitable. at a house where we used to live the soil was very rich and we had thick, deep red stems that were about 600 mm (24") long. We shifted to another town with a slightly different climate and soil that still needs improving more and the stems are still a good colour but not as long.

Thank you for the comments. I live in an area with heavily leached soils and a deficiency at least in iron. I will try using volcanic rock dust and trace elements and see if that makes any difference.

My rhubarb is about 3 years old, but is now producing very thin and short stalks. I have just added manure and compost to the soil, but it doesn't seem to have helped. How can I produce thicker stalks?

Hi Margaret, Is your rhubarb getting enough deep watering? They prefer very deep soil and enough moisture to keep them growing. In my garden I get skinny stalks when my rhubarb is thirsty, and lovely thick stalks when it has adequate water.

Most of the rhubarb plants available for sale are grown from seed. These can vary in colour from red to green and the stem thickness can vary from not much more than pencil thickness up to 2.5 cm (1") thick.If you have fed the plants well and they have plenty of water and look healthy you may not be able to improve the stem thickness. If you have just applied the compost and manure I would wait until the new growing season spring and see how well they take off then.

I would remove a few stalks to provide rhe space for the remaining ones to grow. Keep watering regularly. Give it a couple of weeks. Good luck

How well can I grow rhubarb in North West Arkansas ? Thank You

You should be able to grow rhubarb in NW Arkansas. Plants are normally available in the winter from nurseries. Burpee's also list them. If your winter is severe put a good layer of straw over them to help insulate them.

hi plant is getting a brown spot on its leaf then it spreads to the stems & dies can you give me some idea what the problem is thanks

What you describe is a fungal disease. When harvesting rhubarb remove any affected leaves and any outer tired or shabby leaves. This will aid good air circulation. Water your plants at the base in the mornings rather than overhead so the plants will not be damp overnight. Discard affected leaves so as not to spread the fungus in the garden. You could also use a fungicide if necessary but good hygiene is always a good practice. Trust this helps.
