How many potatoes can I plant in a pot or a bag? When you grow potatoes in containers, you can plant 1 to 2 potatoes in a 5 gallon bucket, 2 to 4 potatoes in a 10 gallon pot, 4 to 6 potatoes in a 15 gallon pot or bag.

Containers holding potatoes will dry out more quickly than the soil in your garden. Careful monitoring is required to keep your potato container uniformly moist. Potatoes need at least an inch of water a week, 1 1/2 inches for maximum production, particularly after tubers have started to form.

Add more soil to the container as the plants grow, until the soil is 1” below the top rim of the container. You can alternate “hilling” with potting soil and garden soil to keep cost down, just don't use only garden soil (see below), and be sure to water your containers every morning that it isn't raining.

The potatoes should mature in 70 to 90 days. You can also choose a variety from the supermarket that you enjoy. Be aware that some potatoes take 120 days until harvest, so you need a long growing season for these types of potatoes.

Potatoes grown directly into the ground will provide a better yield by weight than those grown in containers.

You can plant between 5 and 7 potato seeds in a 20-gallon bag. Each seed can yield you from 3 to 6 potatoes depending on how many eyes it has to sprout from.

How often should I feed potatoes in containers? ›

Place the potato bag in a bright, frost free position, water regularly, and wait for your plants to grow. Feed potato plants every other week with potato fertiliser and water the bags whenever the compost shows signs of drying out.

But, planting the seed potatoes too deeply from the start can cause them to rot before they sprout. At the very least, it makes harvesting very difficult at the end of the growing season because the potatoes are buried so deeply.

A deep container is ideal for growing potatoes year-round, particularly early potato varieties. Drainage will be helped by adding some material such as a pot, broken brick or ceramic, or even polystyrene to your container then fill with about 4 inches of soil or medium.

Too much water right after planting and not enough as the potatoes begin to form can cause them to become misshapen. Stop watering when the foliage begins to turn yellow and die off.

Most commercial chemical feeds specific for potatoes are balanced as 2:2:3, that is equal amounts of nitrogen and phosphorus with half as much again of potash or 3:5:5. The nitrogen and phosphorus will feed the haulm (foliage) and root system with the potash feeding the tubers themselves.

A month or two after they've been planted, potatoes need lots of nitrogen, so a fertilizer with an NPK of 34-0-0 is the best choice. An NPK of 12-12-17 or 14-7-21 is best for the last couple of months before harvest when the plants require more potassium.

Also add some epsom salt to the soil when planting to help provide a boost of magnesium that will help build cell walls of the potato. With these simple tips you'll be well on your way to growing a healthy potato crop that you can put in your root cellar and eat off of for several months of the year.

How many potatoes can I plant in a 25 gallon container? ›

A pound of seed potatoes will produce a good crop of tubers in either a single 30 or 45 gallon Smart Pot, or two smaller 20 to 25 gallon fabric planter pots. For smaller harvests, plant a quarter- or half-pound of seed potatoes in a 10 or 20 gallon container respectively.

As a general rule each potato plant needs about 2.5 gallons. Therefore a 10 gallon bag will support four potatoes while a 5 gallon bag will accommodate 2 potato plants. If you want to grow a large number of potato crops, it is best growing them in separate bags rather than one huge bag.

First earlies – such as the Yukon Gold (which I'm planting here), take around 10-12 weeks. Second earlies – like Kennebec or French fingerling potatoes, take approximately 12-14 weeks. And finally, main crop potatoes – these include russets and blue potatoes, and these can take up to 20 weeks to grow.

Potatoes do not need to be soaked in water before planting, but they can be if you would like, as it is beneficial. Soaking potatoes can help them germinate more quickly and help them establish a better root system. Soaking potatoes in water before planting can help them to sprout faster and produce higher yields.

March is traditionally the most popular time of year to plant potatoes in pots and bags. Having said that, if you choose the right variety you can plant them in April and May and still have a crop before autumn.

Potatoes grow surprisingly well in a pot. It's the ideal way of growing them if you're short on space – you can even grow them on a patio or balcony. Growing potatoes in pots is especially suited to first early and second early potatoes, which grow fast and are at a premium in the shops.
