Answer: Sweet peas need a very rich soil well prepared with plenty of organic matter such as compost or well rotted stable manure and bedding dug into it. The pH should be above 6.0. They require a moist yet well drained soil (meaning not soggy). Annual sweet peas need sunshine to grow their best and yet must have a cool location out of hot sun. Sometimes a location in full morning sun is better. Plant them in very early spring so that they can grow and bloom before the weather turns hot. I hope this helps.
