It's okay to plant rhubarb now. Rhubarb often dies back in the winter in cooler areas. It doesn't like a hot position so plant it so that it gets shelter from the afternoon heat if necessary. Rhubarb is a 'gross' feeder which means it likes lots of manure and water to give the best results. A couple of handfuls of Blood & Bone, a shovel full of old manure or a handful of pelletised manure placed in the bottom of the planting hole and covered with a layer of soil before planting will give good results. Most rhubarb that is sold is grown from seed and the resulting stem colour can range from all green to a good red. The flavour will still be the same. To redden it up when cooking add a few drops of cochineal (a natural red colouring) while it is cooking. To avoid adding sugar try using Stevia which is available at many shops. Stevia is a non calorie extract from the Stevia plant and is much better for you. All the best.
