I don't think petite is a height so much as a body shape. I have seen tall women shopping in the petite section because they have a short waist or shorter arms or wanted a skirt that fits them better than the regular ones, and I have seen smaller women shopping in the junior/misses/womens section for similar reasons.
Sweet clover needs a high pH, 6.0 or higher, for proper nodulation to occur, and it has a higher calcium requirement as well. Sweet clover is able to obtain phosphorus from relatively unavailable soil phosphates and will grow on soils where alfalfa, red clover or ladino will fail.
Soil pH. Pea plants can grow in a range of soil pH levels, between 5.8, slightly acidic, and 7, neutral. Purchase a soil testing kit from a garden center to test soil pH. If the soil is too alkaline, add sulfur, if it is too acidic, add lime.oil Drainage. Peas do not like to sit in wet soil, so choose a spot with good drainage. If you have heavy clay soil, which absorbs and holds water, add humus materials to improve drainage. Working leaves, grass clippings or straw into the soil will improve soil texture, drainage and nutrient content.
