Soil pH measures the acidity of the soil. Romaine lettuce requires a neutral pH between 6.0 and 6.5. Existing successful vegetable garden soil usually falls within this range. For new beds, a soil test determines the pH. Use a home testing kit or take a soil sample to a testing laboratory to determine pH.omaine lettuce (Lactuca sativa) produces an upright head of large loose leaves. The crisp leaves and firm central rim make it a prized fresh addition to salads.
