Growing potatoes in a raised bed can be a game-changer for any gardener. Raised beds provide excellent drainage, which is crucial for potatoes that don't like wet feet.
Potatoes are a cool-season crop, which means they thrive in temperatures between 40°F and 70°F. This makes them perfect for early spring or late summer planting in most climates.
To get started, choose a spot with full sun and well-draining soil. Potatoes can rot if the soil is too moist, so make sure it drains well.

Preparing to Plant
Plan to plant your potatoes out 2-4 weeks before your last frost. This timing is crucial to ensure your potatoes have enough time to mature before the cold weather sets in.
To get a head start, start greensprouting (also called chitting) your potatoes 4 weeks before planting. Place the potatoes rose end up in egg cartons near a window, where they'll receive warmth and light to help them break dormancy.

The goal of greensprouting is to grow short, dark green leafy sprouts. This is in contrast to growing spindly, leggy sprouts, which can lead to a weaker harvest.
If your potatoes are larger than a chicken egg, consider cutting them up into smaller pieces. This will give you more pieces to plant and can be a frugal way to extend your planting area.
Here's a rough guide to dividing potatoes:
Try to divide them into pieces no smaller than an egg with no less than three sprouts per piece. Do this at least a week before planting, so the cuts have time to heal.
Planting and Caring
Raised beds are a great option for growing potatoes, and you can still get a good harvest even if your beds aren't very deep.
You can grow potatoes in raised beds and get a better yield than if you were to plant them directly in the ground.
To grow potatoes in raised beds, you've got two main options: planting and hilling.
The key to growing potatoes in raised beds is to add mulch as the plants grow, which encourages more tuber growth.
Timing is everything when it comes to adding mulch - you want to cover the lower stems of the plant when it's in its vegetative growth stage.
Adding mulch too late won't give you the increased yields you're looking for, but it will still protect the developing tubers from sunlight.
Sunlight causes potatoes to produce chlorophyll and turn green, which makes them toxic.

Soil and Bed Setup
To grow potatoes in raised beds, you'll want to focus on setting up the soil and bed correctly. Make sure your raised bed is at least a foot deep to accommodate the potato plants' growth.
For better drainage and soil depth, it's recommended to have raised beds that are two feet deep, as seen in Example 2. This will also help prevent crops from struggling in wet years.
Before planting, ensure your raised bed is well-drained and the soil temperature is at least 45˚, as mentioned in Example 4. This will give your potatoes the best chance to thrive.

Soil Mix for Plant Bed
When preparing the soil mix for your plant bed, it's essential to get it right. A good soil mix can make all the difference in the health and productivity of your plants. For potatoes, a blend of 2 parts screened topsoil, 1 part compost, and 1 part peat moss is a great starting point.
The peat moss helps to lighten the heavy soil, improves moisture retention, and slightly acidifies the soil – something potatoes prefer.
In fact, as seen in Example 6, this specific blend was used to fill raised beds for potato cultivation, resulting in healthy and productive plants.
To create this blend, you can mix together equal parts of compost and peat moss with 2 parts of screened topsoil. This will give you a well-balanced mix that will support the growth of your potatoes.
Here's a rough estimate of the mix ratio:
- 2 parts screened topsoil
- 1 part compost
- 1 part peat moss
This mix ratio is a great starting point, but feel free to adjust it based on your specific soil conditions and plant needs.
How Many?
It's actually really difficult to assess how many potatoes you get from each plant, and it can vary depending on the type of potato you choose.
Some potatoes grow very large, but maybe only a few tubers per plant.
You can count on getting 1-2 lbs (around 0.5-1 kg) per seed potato.
In my experience, growing potatoes in a raised bed can yield 10-20 lbs (around 5-10 kg).
My goal is to let the tubers grow large, rather than harvesting them too soon.

Growing and Harvesting
Growing potatoes in a raised bed is a great way to get an early harvest. You can start harvesting in early summer, around 100 days after planting, when the plants have died back.
To get an even earlier start, try chitting your potatoes indoors for around four weeks before planting. This helps the potatoes develop roots and leaves, making them grow faster when they're actually in the ground.

Research the variety you want to use and keep track of the development time, which can range from 100 to over 200 days. Some varieties are specifically designed for early harvests.
You can harvest your potatoes when the flower buds start to wilt or drop off the plant, or when the foliage begins to yellow and dry out. This often coincides with the first frost.
Here are some general tips for harvesting potatoes from raised beds:
- Use a potato fork to lift the tubers from the ground gently.
- Remove any mulch you applied and dig with a hand spade to avoid damaging the potatoes.
- Don't wash the potatoes if you plan to store them long-term; simply dust off the soil instead.
An Early Harvest
Growing potatoes in raised beds offers the perfect opportunity for an early harvest.
If you live in a zone with cold winters, like zone 3, you can start harvesting your potatoes in early summer, around April, if you plant them at the right time.
To ensure a successful harvest, make sure the temperature is above freezing before planting your potatoes, as they can rot in very cold soil.
Planting seed potatoes that have been chitted, or allowed to develop roots and leaves indoors, can give them a good start and help them grow faster in the ground. This process can take around four weeks, and it's worth the extra effort for a faster harvest.

Harvesting

Harvesting potatoes can be a fun and rewarding experience, especially when you know what to expect. You can harvest early potatoes when the flower buds start to wilt or drop off the plant.
Pay attention to the foliage of your potato plants, as they will begin to yellow and dry out before you can harvest them. This often coincides with the first frost.
For raised beds, harvesting is easier because you don't have to stoop down, but you may need to climb onto the bed rails to get leverage with a potato fork. This is especially true for long-season storage varieties.
If you're growing potatoes in straw, you can simply peel back the layers to unearth your spuds. This is a great option because it's easy and gentle on the tubers.
To harvest potatoes from a raised bed, you'll want to dig with a hand spade to avoid damaging any of your potatoes. Try not to disturb the roots of any other plants you have planted in the bed.
When harvesting potatoes for long-term storage, don't wash them. Instead, dust off any excess soil and keep them dry and a bit dusty to help them keep longer.

Grow – Tips
Growing your own potatoes can be a fun and rewarding experience. Research the variety you want to use to ensure you're getting the best results.
To get started, make sure to chit your potatoes indoors to give yourself an extra early harvest. This simple step can make a big difference in the end.
Keep track of the development time for your potatoes, as it can take anywhere from a few weeks to several months for them to be ready to harvest. Early potatoes typically take around 7-10 weeks to mature.
If you're growing early potatoes, consider planting them in a tighter row than you would with later potatoes. This will give them the best chance to thrive and produce a bountiful harvest.

Post-Harvest
Potatoes have been a food staple for hundreds of years for a good reason - they're prolific and simple to grow.
To store potatoes for months, you don't even need a root cellar, but it certainly does help.
Let potatoes cure for 7-12 days in a dark and dry place, such as a layer of newspaper, a dry tarp, or large pieces of cardboard, with good airflow around them.
A fine layer of dirt helps to protect potatoes, allowing them to be stored longer.
If you've got any potatoes cut or pierced by your garden fork, pull those and eat them right away.
Thick skin is the goal of curing potatoes, so aim for that when selecting your harvest.
Tips and Considerations
Growing potatoes in a raised bed can be a rewarding experience, but it does require some planning and attention to detail.
Researching the variety you want to use is crucial, as different types of potatoes have different development times and growing requirements.
Keep track of how many weeks it takes before you can harvest your potatoes, as this will help you plan when to plant and when to expect a yield.
