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

can you compost the toxic parts of the plant for use in other parts of garden?

It will grow well in a large pot. Remember it is a gross feeder and likes plenty of fertiliser.
