Wiggle Worms | How to Grow Foolproof Potatoes in Bags

If there is one vegetable you absolutely must grow with kids in Ireland, it's the humble spud! They thrive in our climate, they don't need a greenhouse, and harvesting them is exactly like digging for buried treasure.

You don't even need a garden bed for this. Old heavy-duty compost bags or reusable potato planters work perfectly on a patio or balcony.

What You Need:

  • Seed Potatoes: Buy these from a garden centre. 'First Earlies' are the best for kids because they grow the fastest!
  • A Large Bag: A specialised potato bag, or an empty 50L compost bag.
  • Compost: Peat-free multi-purpose compost.

Step-by-Step Guide:

  1. Chit the Spuds: Put the seed potatoes in an old egg carton on a bright, frost-free windowsill. Leave them there until they grow little green shoots.
  2. Planting: Roll down the sides of your bag. Put about 15cm (6 inches) of compost at the bottom. Place 3 to 4 seed potatoes on top.
  3. Earthing Up: As the green leafy stems grow up through the soil, keep adding more compost to cover the stems.
  4. The Treasure Hunt: Once the plant flowers and the leaves die back, tip the whole bag upside down and let the kids rummage!

⚠️ Frost Warning

Potato leaves hate late Irish frosts. If a cold snap is forecast in May, throw a layer of horticultural fleece or an old bedsheet over your potato bags at night to keep them warm.
