Planting potatoes in pots is a great way to enjoy a bountiful harvest of delicious, homegrown potatoes, even if you have limited space. Whether you live in an apartment, have a small garden, or simply want to try your hand at container gardening, growing potatoes in pots can be a rewarding and productive experience. In this article, we’ll explore the ins and outs of planting potatoes in pots, covering topics such as choosing the right variety, preparing the soil, and providing the necessary care for a successful harvest.
Choosing the Right Variety of Potato
When it comes to planting potatoes in pots, selecting the right variety is crucial. Not all potato varieties are suitable for container growing, so it’s essential to choose a variety that is compact, produces small to medium-sized tubers, and has a relatively short maturation period. Some popular varieties for container growing include ‘Nicola’, ‘Charlot’, and ‘Pentland Javelin’. These varieties are known for their high yields, disease resistance, and adaptability to container growing.
Factors to Consider When Choosing a Variety
When selecting a variety, there are several factors to consider, including:
The size of the tubers: Compact varieties that produce small to medium-sized tubers are ideal for container growing.
The maturation period: Look for varieties with a relatively short maturation period, typically around 70-100 days.
Disease resistance: Choose varieties that are resistant to common potato diseases, such as late blight and scab.
Taste and texture: Consider the flavor and texture you prefer, as well as the intended use of the potatoes (e.g., boiling, roasting, or mashing).
First and Second Early Varieties
First early and second early varieties are popular choices for container growing. These varieties mature quickly and produce small to medium-sized tubers. First early varieties, such as ‘Pentland Javelin’, mature in around 70-80 days, while second early varieties, like ‘Nicola’, take around 90-100 days to mature. These varieties are ideal for container growing, as they produce a high yield and are relatively low maintenance.
Preparing the Soil and Pots
Before planting potatoes in pots, it’s essential to prepare the soil and containers properly. The soil should be well-draining, rich in organic matter, and have a pH between 4.5 and 7.0. You can create your own potato-growing mix by combining peat moss, compost, and perlite or vermiculite.
Soil Requirements
Potatoes have specific soil requirements, including:
A pH between 4.5 and 7.0: Potatoes prefer a slightly acidic to neutral soil pH.
Good drainage: Potatoes don’t like wet feet, so make sure the soil is well-draining to prevent waterlogged soil.
High organic matter content: Potatoes benefit from a soil rich in organic matter, such as compost or well-rotted manure.
Choosing the Right Pots
When it comes to choosing pots for growing potatoes, size and material are essential considerations. The pots should be at least 15-20 cm deep to allow for good root growth and tuber formation. You can use plastic, wooden, or clay pots, but make sure they have drainage holes to prevent waterlogging.
Pot Size and Depth
The size and depth of the pot will depend on the variety of potato you’re growing. As a general rule, the pot should be at least 15-20 cm deep and have a volume of around 10-20 liters. This will provide enough space for the roots to grow and the tubers to form.
Planting the Potatoes
Once you’ve prepared the soil and pots, it’s time to plant the potatoes. You can start by chitting the seed potatoes, which involves allowing them to sprout before planting. This will give the potatoes a head start and improve yields.
Chitting the Seed Potatoes
To chit the seed potatoes, place them with the ‘eyes’ (small buds on the potato) facing upwards in a light, cool place. The temperature should be around 10-15°C, and the light should be indirect. Allow the seed potatoes to chit for 2-4 weeks, or until they have developed short, green shoots.
Planting the Chitted Seed Potatoes
Once the seed potatoes have chitted, you can plant them in the pots. Fill the pot with a layer of soil, then place the chitted seed potato on top. Add more soil, leaving about 5-7 cm between the soil surface and the top of the pot. Water the soil gently but thoroughly.
Caring for the Plants
After planting, it’s essential to provide the plants with the necessary care to ensure a successful harvest. This includes:
Watering: Keep the soil consistently moist, but not waterlogged.
Fertilization: Feed the plants with a balanced fertilizer once a month.
Pest and disease control: Keep an eye out for pests and diseases, such as slugs, aphids, and late blight.
Harvesting the Potatoes
After around 70-100 days, depending on the variety, the potatoes will be ready to harvest. You can start by checking for tubers by gently feeling around the soil with your fingers. When the tubers are ready, carefully tip out the pot and gather the potatoes.
Timing the Harvest
The timing of the harvest will depend on the variety and the weather conditions. As a general rule, first early varieties will be ready to harvest around 70-80 days after planting, while second early varieties will take around 90-100 days.
Post-Harvest Care
After harvesting, it’s essential to dry the potatoes thoroughly to prevent rot and spoilage. You can do this by spreading the potatoes out in a cool, dark place with good ventilation. Allow the potatoes to dry for several hours or overnight before storing them in a cool, dark place.
In terms of the potato yield from container gardens,
| Container Size | Yield per Container |
|---|---|
| Small (10-15 liters) | 2-4 potatoes |
| Medium (20-30 liters) | 5-8 potatoes |
| Large (40-50 liters) | 10-15 potatoes |
As you can see from the table, the yield per container will depend on the container size and the variety of potato being grown. By following the guidelines outlined in this article and using the right variety and container size, you can achieve a bountiful harvest of delicious, homegrown potatoes.
In conclusion, planting potatoes in pots is a fun and rewarding experience that can provide you with a delicious and bountiful harvest. By choosing the right variety, preparing the soil and pots, and providing the necessary care, you can enjoy a successful and productive potato crop. Remember to start with healthy seed potatoes, provide good soil and drainage, and keep the plants well-watered and fertilized. Happy gardening!
What are the benefits of growing potatoes in pots?
Growing potatoes in pots offers several benefits, including flexibility and control over the growing conditions.

By taking the time to prepare the soil properly, you can create a healthy and productive environment for your potatoes to grow and thrive.
How often should I water potatoes grown in pots?
Watering is a critical aspect of growing potatoes in pots, as the soil can dry out quickly in containers. The frequency of watering will depend on the weather, soil mix, and size of the container. As a general rule, aim to keep the soil consistently moist but not waterlogged. Check the soil daily, and water when the top 1-2 inches of soil feels dry to the touch. You can also use a moisture meter to get a more accurate reading. It’s essential to avoid overwatering, as this can lead to rot and other problems.
During hot or dry weather, you may need to water your potatoes more frequently, possibly even daily. However, during cooler or wetter weather, you can reduce the frequency of watering to every other day or even every few days. It’s also important to avoid getting water on the leaves or foliage, as this can encourage disease. Instead, aim the water at the soil, and try to keep the foliage dry. By watering carefully and consistently, you can help your potatoes grow and thrive, and enjoy a healthy and productive harvest.
How much sunlight do potatoes need to grow in pots?
Potatoes need a significant amount of sunlight to grow and produce well in pots. Aim to provide your potatoes with at least 6 hours of direct sunlight per day, although 8 hours or more is even better. If you’re growing in a location with limited sunlight, you can also consider using grow lights to supplement the natural light. However, be careful not to provide too much direct sunlight, as this can cause the soil to dry out quickly and potentially scorch the foliage.
When placing your potato containers, choose a location that receives plenty of sunlight and is protected from harsh winds and extreme temperatures. South-facing balconies, patios, or decks are ideal for growing potatoes in pots, as they receive plenty of sunlight and warmth. If you’re growing in a shadier location, you can also consider using a trellis or other support to help the plants grow upwards and maximize their exposure to sunlight. By providing your potatoes with the right amount of sunlight, you can help them grow and thrive, and enjoy a bountiful harvest of delicious homegrown spuds.
How do I harvest potatoes grown in pots?
Harvesting potatoes grown in pots is a relatively simple process. Start by carefully removing the soil from the container, taking care not to damage the tubers. You can do this by gently tipping the container on its side and scooping out the soil with your hands or a small trowel. As you remove the soil, you should start to see the potatoes nestled in the soil. Gently lift them out of the container, taking care not to damage the tubers or the roots.
For “new” potatoes, you can start harvesting about 70-100 days after planting, when the plants are still green and the tubers are small. For maincrop potatoes, wait until the foliage has died back and the tubers have matured, usually around 100-120 days after planting. Once you’ve harvested your potatoes, brush off any excess soil and store them in a cool, dark place to keep them fresh. Be sure to leave some tubers in the container to produce a second crop, if desired. By following these simple steps, you can enjoy a bountiful harvest of delicious homegrown potatoes from your pots.
