How to use growbags for potatoes

Choosing the Right Potato Varieties

When it comes to potatoes, there’s a variety to suit everyone’s taste. In the UK, popular varieties include ‘Desiree’ (red-skinned, yellow flesh), ‘Maris Piper’ (white skin and cream flesh, excellent for chips), and ‘Charlotte’ (yellow skin and flesh, perfect for salads). Early varieties such as ‘Swift’ or ‘Rocket’ can be harvested sooner and typically have a smoother texture.

Getting Started: Chitting

Chitting is the process of pre-sprouting potatoes before planting, speeding up the growing process. To chit your potatoes, place them in a light, cool, frost-free place (10-15°C) with the ‘rose’ end facing upwards. This end is usually more indented and has the most ‘eyes’. After 2-4 weeks, when sprouts are about 2.5cm long, they’re ready to plant.

Preparing Your Grow Bag

For growing potatoes, it’s recommended to use a bag with a capacity of around 40 litres. Make sure there are sufficient drainage holes at the bottom to avoid waterlogging.

Fill the bag with about 10-15cm of good-quality compost mixed with a slow-release organic fertilizer.

Planting Your Potatoes

Place the chitted potatoes on top of the compost, with sprouts pointing upwards. As a rule of thumb, aim for 3-4 seed potatoes in a 40-litre bag.

Afterwards, cover them with another 10cm of compost. Water the compost until it’s damp but not waterlogged.

Growth and Care

As shoots begin to appear, add more compost to cover them, leaving only a few cm exposed. This process, known as ‘earthing up’, encourages more potatoes to grow. Stop adding compost when you reach about 5cm from the top of the bag.

Keep your grow bag in a sunny spot, watering regularly to maintain evenly moist soil, but never allowing it to become soggy. To check, stick a finger into the soil; if it feels dry beyond the first joint, it’s time to water.

Harvesting Your Potatoes

The time of harvest will depend on the variety you’ve chosen. Early varieties can be harvested around 10 weeks after planting when the flowers begin to open. Maincrop varieties need longer, typically 15-20 weeks, and are usually harvested when the foliage turns yellow and dies back.

To harvest, carefully tip out the contents of the bag. You’ll find your fresh home-grown potatoes throughout the compost.

Wrapping Up

Growing potatoes in grow bags is a practical and rewarding gardening activity that anyone can do, regardless of the amount of available space. With the correct care and attention, you’ll be able to enjoy fresh
