Potatoes: A Comprehensive Guide to Growing 2024

The Wonderful World of Potatoes

Welcome to my blog on how to grow potatoes! Potatoes are incredibly versatile and loved by many. In this guide, we will explore the different types of potatoes, how to achieve a bountiful harvest, and tips for growing in small spaces.

Whether you’re a seasoned gardener or a beginner, this blog will provide you with all the information you need to successfully grow your own potatoes.

Types of Potatoes

Potatoes are classified based on how long they take to go from planting to harvest. There are three main categories: first early, second early, and late season or maincrop potatoes.

First Early Potatoes

First early potatoes are the quickest to mature, taking as little as 10 weeks from planting to harvest. These potatoes have thinner skins and are often used for salads. They don’t require peeling, making them a convenient choice for quick and easy meals.

Second Early Potatoes

Second early potatoes take 12 to 14 weeks to mature. They are typically harvested from midsummer onwards. These potatoes are versatile and can be used for boiling, mashing, or in salads.

Late Season or Maincrop Potatoes

Late season or maincrop potatoes take the longest time to mature. They are ready for harvest from late summer onwards. These potatoes require more space to grow, but they offer a larger yield and can be stored for months under the right conditions.

With hundreds of potato varieties available, it’s important to choose the right one for your needs. Consider whether you prefer a fluffy, floury potato for baking and mashing, a firm and waxy potato for salads, or an all-purpose potato that can be used in various dishes. Additionally, look for varieties that are resistant to common pests and diseases such as slugs and nematodes.

Preparing Seed Potatoes

Before planting your potatoes, it’s beneficial to sprout or “chit” them. While not necessary, sprouting your seed potatoes can give you a head start, especially in colder temperatures. To sprout your potatoes, lay them with the end that has the most eyes facing upwards.

If your potatoes are large, you can cut them in half as long as each half has at least two or three eyes. Place the potatoes in a bright, cool, and frost-free location. Make sure to keep them out of the dark, as this can result in long, soft, and spindly shoots. Short and stubby sprouts are ideal for planting.

It’s important to note that potatoes can be either determinate or indeterminate. Determinate potatoes produce their tubers in one layer, while indeterminate potatoes produce them in multiple layers. This distinction affects how you grow and care for your potatoes.

Growing Potatoes in Containers

One of the most accessible ways to grow potatoes is in large containers or tubs. This method is ideal for those with limited space, as containers can be placed on terraces, balconies, or in any spare corner. Use a container that is at least 30 liters or 8 US gallons in size to ensure your potatoes have enough room to grow and don’t dry out too quickly.

To prepare your growing medium, combine sieved garden compost, old potting mix, and fresh potting mix in a three-way split. This mixture saves on cost and provides the necessary nutrients for your potatoes. Add a small handful of general-purpose organic fertilizer to boost growth. Fill the container one-third full with the potting mix, place two seed potatoes, and cover them with another one-third of the mix.

Repeat this process with two more seed potatoes, setting them at right angles to the previous ones. Finally, cover the potatoes with the remaining potting mix. Water the container thoroughly, and consider adding a mulch of straw or dried grass clippings to insulate the soil and retain moisture.

Planting and Caring for Potatoes

When planting your potatoes, space them approximately 14 to 16 inches apart for early and midseason varieties, and 18 inches apart for late season or maincrop varieties. Dig a hole 6 to 8 inches deep and place the seed potato inside. Cover it with soil and water thoroughly.

Determinate potatoes require only a mulch to protect any tubers that poke through the soil. Indeterminate potatoes, on the other hand, benefit from hilling or earthing up. Use a hoe to draw up soil around the stems of the plant, creating more room for the tubers to grow. Hilling or earthing up should be done once or twice until the foliage closes in.

Water your potatoes regularly, aiming for the base of the plants to avoid wetting the leaves. Container potatoes may require more frequent watering due to their smaller space and quicker evaporation. Watch out for potato blight, a fungal disease that can affect your crop. To prevent blight, choose early maturing or blight-resistant varieties, water at the base of the plants, and provide good ventilation to reduce humidity. If blight does strike, cut back the foliage, wait for the spores to die off, and harvest the potatoes as soon as possible.

Harvesting and Storing Potatoes

The timing of your potato harvest depends on the variety. Early potatoes can be harvested while the foliage is still green and lush, usually when the plants are coming into flower. Container potatoes can be easily tipped out, while in-ground or in-bed potatoes require more care to avoid damaging the tubers. Start by carefully digging around the outside of the plant and work your way inwards. Lift the plant from underneath, being cautious not to spike the potatoes with the fork. Handle the potatoes gently to avoid bruising them, and consume them as soon as possible.

Late season or maincrop potatoes are typically harvested when the foliage begins to yellow and die back. Stop watering the plants a couple of weeks before harvesting to allow the skins to thicken. Cut back the foliage for better visibility, and carefully dig up the potatoes. Store perfect, blemish-free potatoes in a breathable sack in a cool, dark, and well-ventilated location. Avoid storing potatoes that have been damaged or are green, as they won’t keep well.

In Conclusion

Growing potatoes is a rewarding experience that anyone can enjoy. By choosing the right variety, sprouting your seed potatoes, and providing proper care, you can have a successful harvest. Whether you have a large garden or limited space, potatoes can be grown in containers or in the ground. Remember to water your plants adequately, protect them from diseases like blight, and harvest them at the right time. With these tips in mind, you’ll be on your way to growing your own delicious potatoes in no time!
