The other greens may withstand medium frosts. Greens may be grown on a variety of soils. Loams will generally produce the greatest yields but for early spring growth and overwintering, sandy loams are best. Soils should be well drained, rich in organic matter and thoroughly tilled. A pH of 6.0 to 6.5 is desirable for all of the greens except spinach, which thrives best in a soil pH 6.5 to 6.8.
Leafy vegetables require quick, continuous growth for best quality.
They especially need nitrogen for good color and tender-ness. Follow soil test results. Sidedress with 15 to 30 lb of nitrogen per acre 3 to 5 times after seeding or transplanting. Shallow cultivation is a must. Use a rolling cultivator or bunting cultivator.
