Peas are the perfect vegetable to grow in a container garden—they grow quickly and don’t need much attention, but will yield a surprisingly large harvest for a little bit of effort. There are just a few must-haves when it comes to growing peas, mainly full sunlight and moist soil. Peas prefer cool conditions, so planting them early in the season is your best bet for a plentiful harvest. Once your weather begins to get too warm, your peas will stop producing—at that point, you can pull them up and start a different heat-loving vegetable in the same container.

Peas take between 60 and 70 days to grow to maturity from seeds, so if your growing season is long enough, it may be possible to plant an early crop for a late spring harvest, convert your planter to another fast-growing vegetable for the heat of summer, then plant a second pea crop in late summer for a fall harvest.

Some favorite types of peas for container gardening include:

  • Sugar snap peas
  • English peas (including the 'Little Marvel,' 'Tom Thumb' and 'Early Frosty' varietals)
  • Snow peas

    What You'll Need

    Equipment / Tools

    • Garden trowel
    • Work gloves

    Materials

    • Large planting container with drainage holes
    • Plastic screening
    • Potting soil
    • Fertilizer (if needed)
    • Pea seeds
    • Legume inoculant (optional)

    Instructions

    1. Prepare Your Container

      Cut a piece of plastic screening that's large enough to cover the hole in the bottom of the container you've chosen. If you don't have screening, you can also use a coffee filter or a piece of paper towel to cover the drainage hole.

      Gardening Tip

      If your container is very large, you can fill the bottom one-third with clean plastic containers, soda bottles, or anything that will take up some space but won't impede water flow. This can save you money on ​potting soil and make your container lighter should you have to carry it around. If you do fill the bottom, separate your soil from your filler material by cutting plastic screening and putting it over the filler before adding potting soil (this makes clean-up at the end of the season much easier). Don't put gravel in the bottom of your pot; this oft-advised method really doesn't work.

    2. Fill Your Container With Potting Mix

      Pour potting mix into your container, making sure to leave at least three inches to the rim. If your potting soil doesn’t have fertilizer already including in its mixture, add in a general, all-purpose formula. Keep in mind, peas don't need much fertilizer—if you use too much, the nitrogen (a common ingredient in most fertilizers) will harm production and the plants will produce large pods with small or no peas inside them. After filling your container, smooth out the soil so it is relatively flat, but not compacted.

    3. Plant Your Pea Seeds

      Though it's not mandatory, treating your pea seeds with a legume inoculant will help give you a bigger pea yield and healthier plants. For faster germination, you can soak your peas in water overnight—then, while they're still wet, shake them in a bag with the inoculant.

      Sprinkle your pea seeds generously and evenly onto the surface of the soil. With the flat part of your hand, press them onto the surface of the soil, then add an additional one to two inches of soil on top of the seeds (make sure not to add more than that, or the peas might have trouble germinating). Water your container deeply with a watering can or a hose nozzle set to a gentle spray.

    4. Set Up a Trellis

      Most peas varietals are climbing plants, so you will need some type of trellis or support system to help stabilize your plant. Bamboo stakes tied together with twine in a triangle shape works well, or you can place your container near a deck or railing that can serve as a "trellis" for the plants. Peas do not naturally cling very well with their tendrils, so you may have to help them get started by using wire ties to secure the stems to the structure.

    5. Care for the Peas

      As your pea seeds germinate, sprout, and begin to grow, keep the soil moist but not wet, and make sure that your containers are getting at least six hours of full sunlight a day. Peas are fairly easy plants, so this is just about the only care required. Since you fertilized the potting soil before planting the seeds, no additional feeding is necessary—peas are legumes that naturally "fix" nitrogen into the soil by absorbing it from the air.

      Harvest your pea pods as they ripen. When it comes to sugar snap peas, harvest them when the pods are still young to get the sweetest and most tender picks. When harvesting English peas that will be shelled, wait until the pods swell, letting you know that the peas inside are big and juicy. For snow peas, pick them from the plant before the peas get too large and tough.
