How to Grow Peas in Containers. Peas are so easy to grow in containers that you can actually grow them indoors or outdoors. In addition to being easy to grow, peas are nutritious, tasty and can be eaten raw or cooked. Use these tips for successfully growing peas in containers.
There are many varieties of peas to chose from, all of which are warm season vegetables. This vegetable only grows well when the air temperature is above 60 degrees, so hold off planting outdoor containers until mid-April to mid-May, depending on your region. Select a bush variety of pea for container growing so the plant won’t outgrow the pot during the summer.
Because the plants must be watered frequently, extra drainage hole will need to be made in the bottom of the selected containers. Use a hammer and nail to make 2-3 extra drainage holes in each container. Cover the bottom of the container with coffee filters to prevent the soil from leaching out during watering.
Start with a good quality potting soil and mix one-half cup of a balanced, 10-10-10 granulated fertilizer into it, then fill the container with the mixture to within 1 inch of the top. Water potting soil until water runs out the bottom of the container. Wait 24 hours to plant peas.
Dig a 2 inch deep hole in the center of the contain and place 2 pea seeds in it. Cover pea seeds with potting soil and water well. Peas plants will need a support system (even bush varieties) and this can be anything you have on hand. Tomatoes cages, bamboo poles, flower trellis, etc., as long as it’s 2-3 feet tall and can support the weight of the plant and developing peas. Push one end of the support into the soil 4 inches behind where the pea seeds are planted, then cover the top of soil with 2 inches of organic mulch, like compost or hay.
Place newly planted container in an area that is partially shaded until the peas germinate. Keep soil moist and be patient for 8-14 days until you see the pea plants emerging from the soil, then move container to a full-sun location.
Keep soil moist, but not soggy, at all times. Feed pea plants once a month with a water soluble fertilize.
