Prepare the soil. Loosen moist soil with a shovel and add 4 inches of compost. Mix well until there are no clumps.
Apply 1/2 cup of 8-8-8 fertilizer to each 10-foot row. Rake the soil over the fertilizer to make beds 3 feet apart. Let the beds rest for a week before planting.
Sow the seeds in April, or three to four weeks after the last frost, when the soil reaches 65 degrees. Plant seeds 1 inch deep with four seeds per foot of row.
Control weeds by adding 2 inches of compost. Hand-pull weeds as they appear to prevent damage to the peanuts developing just under the surface.
Water weekly. Once the plants start flowering, soak the ground 6 to 8 inches deep and don't let them dry out.
Harvest peanuts 120 to 150 days after planting. Dig up yellowing plants and let them dry upside-down in the sun for a day. When hulls are dry, pull them from the plant.
