Question Is it possible to grow Rhubarb in a pot? It would not be practical to plant in the soil as we only have a small sunny garden.
Answer Hi Chris,
Thanx for your question. I'm reluctant to tell anyone what they cznnot do. What I will tell you is, planting a rhubarb plant in a pot presents a number of challenges, however. The pot would have to be quite large, as though you were planting a small, ornamental tree, like something you would move indoors for the winter. Rhubarb has a large, extensive and fleshy root system. The plant can get quite large, as you probably may already know. I would go ahead and try it. I would only put one plant however, in one pot. Make sure the pot is deep.Maybe 45cm/18" deep? Same for the width. Plants in pots need to be watered more often, need frequent applications of well composted manure or some kind of organic fertilizer, and need to be free draining so the roots don't sit in a pool of muddy water which will cause rot. I hope this helps.

Many thanks for your very prompt answer, it's really helped. On my way to purchase a very large pot!
I have been growing plants from seeds for at least 20 years. I have grown literally hundreds of different kinds of vegetables, trees, shrubs, annuals, perennials, tropicals, some cacti, water plants, iris, rose, lilies, cannas, etc. I enjoy starting from seed.
I've been growing my own seeds for 20 years with indoor propagation equipment I built myself. I am also an Allexperts volunteer on the perennial forum. I have completed the Master Gardener course through the Kansas State University Extension. I have experience with a wide variety of seeds and I have also read through Norm Deno's books on seed germination.
