Raised garden beds are simply gardens that are slightly higher than the surrounding native ground.
Peas require a minimum of twelve inches between rows for the best growth. Work your soil six to eight inches deep using a spade or tiller.
Sow peas 1 ½ inches deep to dissuade birds and other seed eaters from discovering them. Plant them two inches apart along the row.
Trellises are also a good practice to maximize your space. Peas are natural climbers and if you do not use trellises, they will start climbing on the other plants around them.
Peas do not require too much watering, an inch per week is adequate. However, if your area is prone to drought, water your peas more frequently.
