Most plants need lots of sunlight. Check what Climate Zone San Diego is in the climate zone section here and look it up if you can grow it.

Stodels Bellville had some for sale, not sure if they still have. I bought mine a month ago from them. If they do not have they can get you one or will tell you where to buy it from.

Try seed selling companies on the net.

I live in Howick KZN. I grow rhubarb in deep pots on the north side of our house (probably too hot) in a compost/soil mix regularly watered. Our area has heavy clay about 200mm below the surface, hence the reason for the pots. Our rhubarb grows many thin stalks (5/8mm dia.) quite slowly and many die before getting above 5mm dia.. The picked stalks are tasty if one has sufficient of them. The plants are about three years old and grown from a split off from a crown. Does rhubarb favour any particular soil PH? More or less water? Any particular soil mix? Require any special feeding? What is ideal soil depth? Your guidance would be appreciated. Thank you.

Try building your garden bed higher or use something to break up the clay - like gypsum or dolomite (I think). ph 5.5 - 6.5. Good soil depth of 12

Hi there. I am making a new rhubarb garden against my west fence so it will be shaded in the hot summer afternoons. When autumn and winter comes around however this area will mostly be in the shade. Is this ok. Thank you

NO plants need sunlight and most need plenty of it. If grown in shade they will be thin and weak. In the heat keep the water up to them. Read up about growing them - google.

I would like to purchase rhubarb plants to grow. Not seeds as they take too long. Can you let me know where I can get them from? Thank you

Any good plant shop should be able to supply rhubarb roots/plants

Give them time - also there is a red and a green variety. Check which one you have, if you can by googling.
