How to Grow Garden Peas in Pots

Growing garden peas in pots is a rewarding and space-saving way to enjoy fresh, homegrown vegetables, especially if you have limited garden space or want to add some greenery to a balcony or patio. With a bit of attention and the right conditions, peas can thrive in containers and provide you with a tasty harvest during the UK growing season.

Choosing the Right Variety and Container

When growing peas in pots, selecting the right variety is important. Look for dwarf or bush pea varieties that are specifically bred for container growing, such as ‘Tom Thumb’ or ‘Little Marvel’. These tend to be more compact and manageable in smaller spaces. Traditional climbing peas can also work, but you’ll need to provide support like a small trellis or bamboo sticks.

Choose a pot that is at least 30cm (12 inches) deep with good drainage holes. Peas prefer well-drained soil to avoid waterlogging, which can cause root problems.

Preparing the Soil and Planting

Use a high-quality, fertile potting compost enriched with some organic matter or a balanced fertiliser suitable for vegetables. Avoid garden soil, which can be too heavy and poorly draining for containers.

Sow pea seeds about 2.5cm (1 inch) deep, spacing them around 5cm (2 inches) apart. If growing climbing varieties, position seeds close enough to your supports to allow shoots to reach upwards comfortably. Water the soil gently after sowing to settle the seeds.

Positioning and Care

Place your pot in a sunny spot, ideally receiving at least six hours of sunlight a day. Peas appreciate cooler temperatures but need good light to produce sweet pods. A sheltered position protects young plants from strong winds or heavy rain.

Keep the soil consistently moist but not soggy. Water regularly, especially during dry spells, but ensure the pot drains well to prevent waterlogging. Mulching the surface with organic material like straw can help retain moisture and keep roots cool.

Supporting Your Peas

If you’re growing climbing varieties, install pea sticks, netting or a small trellis as soon as the seedlings emerge. This support helps keep the plants upright, improves air circulation, and makes harvesting easier.

Feeding and Maintenance

Feed your peas once they start to flower with a balanced liquid fertiliser to encourage pod development. Remove any weeds that may appear in the pot to reduce competition for nutrients.

Regularly check for pests such as aphids, which can affect pea plants. A gentle spray of water or insecticidal soap can help manage these without harming the plants.

Harvesting Your Peas

Garden peas are usually ready to harvest about 12 to 14 weeks after sowing, depending on the variety. Pick the pods when they are well-filled but still tender and sweet. Regular harvesting encourages the plants to produce more pods.

Seasonal Notes

In the UK, the best time to sow peas in pots is from early spring to early summer. Peas prefer cooler weather and may struggle in the heat of midsummer. For a later crop, sow in late summer for an autumn harvest.

Final Thoughts

Growing peas in pots is an accessible and enjoyable way to bring a bit of fresh produce to any outdoor space. With the right variety, good soil and consistent care, you can look forward to sweet, homegrown peas straight from your patio or balcony.
