1 Grow your potatoes in soil with a pH between 5.0 and 6.0. 2  Potatoes grown in soils with a higher pH seem prone to a disease called 'scab', which produces rough spots on the potato. 3  Adding compost or peat will help. 4  Don't plant your potatoes where tomatoes or eggplant were grown the year before.
Test the pH of your soil. Use litmus paper or another testing kit to determine how acidic or neutral your soil is. Onions need a pH range of 6 to 7.5 in order to grow. 1  Drop the pH by digging in manure or compost.  Raise the pH by adding ground agricultural lime into the soil.
