Sutton & Sons Ltd., The Culture of Vegetables and Flowers From Seeds and Roots
“ As the thriving plant covers a considerable space, and there must be a certain amount of traffic on the ground to manage it, there should be one row in the centre of a four-feet bed, with a broad alley on one side; or, better still, mark out a ten-feet space, with a three-feet alley on each side, and in this space plant three rows two and a half feet apart, and the roots one and a half to two feet apart. The planting may be done at any time after the leaves have fallen, late in autumn, and during winter and early spring. ”
