Sandy Loam soils are best. Soils should be deep with a well-drained profile. Heavy clay soils are better avoided. Acid soils with pH below 6 are not suitable.
Ideal soil pH is between 6.2 and 6.8. Beets like soils with high organic matter. Soils should be ploughed, cleaned and levelled before planting. At this time composts and manure can be ploughed in and soil should be mixed to about 300 mm deep.
The area that is to be planted can be ridged either by hand or mechanically. Ridges should be 1200 mm wide and between 200 and 250 mm high. Ridges must be flat topped to form the raised bed that is to be planted.
Beetroot is a cool climate vegetable which does best at temperatures of 14°C to 20°C. Growth and development of the beets is retarded at temperatures of below 5°C and above 26°C.
They can survive mild frost but this damages the foliage and therefore stunts growth and development of the beet underground.
