To grow peas in a small space, you can use containers such as pots, hanging baskets, or planter boxes. Choose dwarf or bush varieties of peas that are well-suited for small spaces. Provide support for the pea plants to climb, such as a trellis or stakes. Make sure to place the containers in a location that receives at least 6-8 hours of sunlight per day. Keep the soil consistently moist but well-drained, and fertilize the plants as needed. Harvest the peas when they are mature and enjoy fresh homegrown produce from your small space garden!
