The humble potato is the unsung hero of the culinary world—a rugged, subterranean tuber that has managed to conquer nearly every kitchen on the planet. Scientifically known as Solanum tuberosum, it belongs to the nightshade family, making it a distant (and much starchier) cousin to the tomato and eggplant.
The Anatomy of a Spud Exterior: They come in a variety of "outfits," from the dusty, thick-skinned Russet to the satin-smooth Red Bliss and the golden-hued Yukon Gold.
Interior: The flesh ranges from snowy white to deep butter-yellow, and even vibrant purples or blues.
Texture: Depending on the starch content, a potato is either waxy (holds its shape for salads) or floury (breaks down into a fluffy cloud for mashing).
A Global Powerhouse Originally cultivated by the Inca in the Andes Mountains, the potato eventually travelled to Europe in the 16th century. It didn’t just provide food; it fuelled empires and sparked population booms. Today, it’s the world's fourth-largest food crop, prized for its ability to grow in tough conditions and its impressive shelf life.
Culinary Versatility There is arguably no food more versatile. You can:
Roast them until the edges are glass-shatteringly crisp.
Boil and mash them with enough butter to make a French chef weep.
Fry them into the universal currency of fast food.
Bake them into a steaming vessel for sour cream and chives
Growing potatoes is remarkably satisfying—it’s essentially buried treasure you can eat. Whether you have a sprawling garden or just a small balcony, you can successfully grow a bumper crop.
Since it is currently late February, you are in the perfect window to begin the first (and arguably most important) step: chitting.
Phase 1: Preparation (February – March) Before the potatoes go into the dirt, they need a "head start."
Buy "Seed" Potatoes: Don't use old potatoes from the grocery store; they are often treated with sprout inhibitors. Buy certified disease-free seed potatoes from a garden center.
Chitting: Place your seed potatoes in an old egg carton with the "eyes" (the little dimples) facing up. Put them on a cool, bright windowsill.
The Goal: Over 4–6 weeks, they will grow short, sturdy green/purple sprouts. When these are about 2.5cm (1 inch) long, they are ready to plant
Phase 2: Planting (March – April) You can plant directly in the ground or in potato grow bags (30-40 litre bags are ideal for patios). Method How to Do It In the Ground Dig a trench about 12cm deep. Space tubers 30cm apart. Cover with soil. In Bags/Pots Fill the bottom 10cm of a bag with compost. Place 2–3 tubers on top, then cover with another 10cm of compost.
Phase 3: The "Earthing Up" Trick This is the "secret sauce" of potato growing. As the green stems grow upward, you must keep burying them.
Wait until the stems are about 15–20cm tall.
Mound more soil or compost around them until only the top few leaves are showing.
Why? This prevents the growing tubers from turning green (and toxic) in the sun and encourages the plant to grow more potatoes along the buried stems.
Phase 4: Care and Harvest Watering: Potatoes are thirsty, especially when flowering. Keep the soil moist but not waterlogged.
Feeding: If growing in bags, use a liquid tomato feed every two weeks once the plants are established.
Harvesting: * First Earlies (New Potatoes): Harvest when the flowers open (usually June/July).
Maincrops: Wait until the foliage turns yellow and dies back (August/September). This allows the skins to set for storage.
Pro Tip: If a late frost is forecast after your green shoots have emerged, cover them with a bit of "fleece" or more soil. Frost can turn your hard work into black mush overnight
The harvest is the "buried treasure" moment. Since it's late February now, if you plant soon, you'll be looking at your first harvest in June or July.
Timing is everything: harvest too early and they’re tiny; wait too long and they might rot or get eaten by slugs.
First Earlies ("New" Potatoes): Harvest 10–12 weeks after planting. These are best eaten immediately while the skins are thin and waxy.
Second Earlies: Harvest 13–15 weeks after planting.
Maincrops: Harvest 15–20 weeks after planting (usually late August to October). These are the ones you "cure" and store for winter.
The Flower Test: When the plants start to flower, the tubers underground are usually about the size of a hen's egg. You can "farkle" (gently dig with your fingers) to check the size.
The Die-Back: For large baking potatoes (Maincrops), wait until the foliage turns yellow and starts to wither. Cut the stems to ground level, wait 10 days, and then dig them up. This toughens the skins so they don't bruise.
The Extraction Process Potatoes are delicate. A nick from a garden tool can lead to rot. Method The Technique In-Ground Use a garden fork, not a spade. Insert the fork about 30cm (1 foot) away from the base of the plant to avoid stabbing the tubers. Lift the entire root ball upward. In Containers This is the easiest way. Simply tip the bag or pot over onto a tarp or lawn and sift through the compost with your hands. It’s cleaner and zero-risk for the potatoes.
Curing and Storage If you aren't eating them tonight, they need a "spa day" to prep for storage:
Dry them out: Lay the potatoes on the soil for a few hours (if it’s dry) to let the dirt dry and fall off. Do not wash them if you plan to store them; moisture is the enemy.
The Dark Room: Move them to a cool, dark, well-ventilated spot for 7–10 days. This "cures" the skin.
The Bag: Store them in hessian (burlap) or paper bags. Never use plastic, or they will sweat and rot.
Warning: If you find any potatoes that have turned green, throw them away or compost them. Green skin indicates the presence of solanine, which is toxic if eaten in quantity
