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.
Strawberries prefer acidic soils with a pH between 5.8 and 6.2. Pine straw mulch is ideal for maintaining this soil acidity so that your plants can thrive. If your soil has a pH over 7.0, the application of pine straw mulch can help lower the pH of the surface soil to the acidic level your strawberry plant requires. Strawberry plants need well-drained soil in order to thrive.
