Knowing how to grow potatoes is an exciting and rewarding hobby, and it’s great even for beginner gardeners who want to learn how to plant potatoes.
You can plant them in various soil types and choose from several species. And, no matter where you live, there’s a potato that will grow in your growing zone…even if that means you have to grow them indoors.
Potatoes are wonderful root veggies and can be used to make everything from soups to candies (that’s right!).
This complete guide outlines everything you should know about how to grow potatoes indoors or outdoors. Read on to also learn the perfect conditions and what month to plant potatoes in your state.
How To Plant Potatoes for the Best Yield
Potatoes are less demanding than other crops and produce a bumper harvest, especially on larger farms outdoors.
To get the most from your crop, there are specific steps you can take.
The following are the seven steps that guarantee generous yields.1,2
How To Grow Potatoes in 7 Steps
The following steps enhance growing conditions.
Step 1: Collect and Prepare the Seeds
First, gather the seed potatoes or small potatoes to plant. You can find some from your local store; ensure you pick the best, disease-free options.
Next, store them somewhere cool and conducive until you see buds sprouting from the eyes and start chitting (They will start to produce small buds).
If dealing with larger seeds, you can cut and cure them first before planting; otherwise, skip to the next step if you have tiny seeds. If you don’t know how to cure potatoes, you need to store the pieces in a cool, airy place for 2-3 days until the callus (protective layer) forms at the top.
Step 2: Check Your Soil
Fortunately, the soil type is the least of your problems in how to grow potatoes. The crop can grow in almost any soil, provided it is well-drained and loose to accommodate the ever-growing tubers underground.
Step 3: Start Planting
If planting in a garden, ensure that you place them in a sunny spot, digging the seeds 3-6 inches deep, with the buds facing upwards. You can set the seeds in columns 12-18 inches apart and rows 24-36 inches wide, then cover them.
For the highest yield, you can add manure and water frequently. Germination should start in the next 14-25 days, evidenced by growth sticking out of the soil.
Step 4: Hilling Potatoes
Although hilling is optional, it is a crucial step that promotes growth during extreme water scarcity because the extra soil layer helps the plant retain water. Otherwise, you can skip this step if all the conditions are favorable.
It entails layering the plant with soil at the base as it keeps growing, but it will only be necessary if it has started flowering.
Step 5: Caring for the Growing Plant
Potatoes are easy to grow, but need some attention to ensure faster growth and a better harvest.
Farmers use compost or manure fertilizer and convert it to liquid form when the leaves start discoloring. It also helps to protect your plants when frost hits and weeds around them.
Additionally, you can plant companion crops and remove enemies that may hinder growth. Lastly, look out for pests and diseases and remove and treat them accordingly.
Step 6: Harvesting
You may harvest your potatoes in 90-150 days after planting, depending on the species you’ve planted and it’s growing conditions and times. You will know when the right time is if you see the leaves wilting.
This is when you will stop watering and prepare for harvest by cutting the stem and leaving it intact for a few days.
Ensure the soil is dry because the tubers will be easier to dig up; you can loosen the dirt using a garden fork or short handled pitchfork and collect the potatoes by loosening them from the soil.

Step 7: Storage
You can dig up the potatoes if you are ready to consume them. Or, they can stay in the ground for up to six months, but if you want to remove them, it is best to know how to store potatoes first.
You can keep them in a bag in a cool, dark, and dry area, ideally at 7-10 degrees Celsius. However, remember not to store them in plastic bags or a scorching place.
A root cellar is the optimum place for storing potatoes til the next year’s planting.
What To Know When Growing Potatoes in Containers
Container planting is suitable for people without a massive yard or garden space. Planting becomes convenient and harvesting easier.3
If you want to plant in bags and containers, combine soil and compost, mix them up, and place the seeds 4-6 inches deep.4
The other steps are similar to planting in the ground because you place the seeds with the buds upwards and place the plants in a sunny place, and water frequently. However, remember to plant away from the corners since the edges usually dry out faster.
Planting Tips for Potatoes Growing Indoors
It is fascinating to find out that you can grow potatoes indoors, like various types of indoor Palm trees, as long as you have a container and access to lighting. The container should be at least half a foot high, hold about two gallons, and have a drainage system.
Alternatively, you can use a soil bag if you don’t have a container but drill drainage holes inside. Light is the most crucial aspect of a plant’s growth, and potatoes need at least 5 hours of sunshine every day; otherwise, you can supplement it with another light source.
You will need two hours of artificial light for one hour of sunshine. The steps for how to grow potatoes are similar to planting in containers outside.
First, fill the planters with loose, fertile soils and dig the seed with the buds facing up.5
Next, dampen the soil by spraying water on the ground every day until you see the sprouts peeking in about 2-4 weeks. Hill the soil once the plants start growing and keep looking after them, watering, fertilizing, and weeding until they are mature and ready to harvest in a few months.

How Long It Takes to Grow Potatoes?
Potatoes can be early, mid, or late season, each taking different times from planting to harvesting. Early-season types take 50-70 days until they are ready to harvest, while mid-season alternatives take 95-110 days.6
Lastly, the late seasons take the longest time, taking more than 110 days until they are ready for harvesting. Therefore, your variety will be based on how long your growing season is.
How To Grow Potatoes in the Best Growing Conditions for Potatoes
As with any other crop, you can expect a better potato harvest if you provide suitable conditions. The following are the needs of the potato.
- Easy access to sunlight for at least 6 hours daily or artificial supplement light twice the duration of natural light.
- Properly drained soil to avoid waterlogging, leading to potatoes rotting.7
- Loose soil allows the roots and tubers to grow effortlessly underground.
- 45-55 degrees Fahrenheit or 7-13 degrees Celsius; higher temperatures are unsuitable.
- Slightly acidic soil of Ph 5.8- Ph 6.5.
Growing Zones for Potatoes (Where To Grow Potatoes)
The first step before undertaking planting projects is knowing the ideal growing zone. Potatoes are hardy plants that can grow in various regions, but they do well in all other hardiness zones except 12a- 13b, which are too warm.
The following are the perfect months to grow potatoes based on your hardiness zone.
USDA Hardiness Zone | Ideal planting time |
2a to 6b | April, May |
7a | January to March, August as a fall plant |
7b | January to March |
8a and 8b | January, February orAugust as a fall plant |
9a and 9b | January, October, and November for fall |
10a and 10b | January, February, and November |
Zones 11a and 11b | December to February |
When To Plant Potatoes
The soil’s temperature and texture are vital considerations when picking the most suitable planting time for your potatoes. The season only partially determines the time if the two conditions above are met.
The perfect temperature should be at least 10 degrees Celsius, and the soil should be wet enough to allow digging but not excessive that it keeps sticking together. It is advisable to let the ground slightly dry; otherwise, the seeds will rot due to waterlogging.8

Growing Potatoes From Seed Potatoes: Chitting Potatoes
One of the most crucial details when growing potatoes from seeds is to do it at the right time.
You want to check your region’s hardiness zone and when to plant based on your state. Otherwise, planting when the soil is too warm or wet may damage the seeds.
Chitting helps eliminate the weakest buds, ensuring you yield from the healthiest and most potent buds. Lastly, you can cut and cure the seed if it is too big because excessive shoots will lead to competition for the available resources, affecting the entire plant.
Begin this process about a month before you plan to plant the potatoes.
- Step 1. Place your seed potatoes in a shallow container (egg carton works well) with the “rose” end up.
The rose end is the end with the most eyes, or indentations where the potato will sprout. - Step 2. Place the containers in a warm, dark area. About room temperature.
- Step 3. After 2 weeks, move the containers to a cooler spot, with indirect light. A covered back porch with average temperature of about 50 degrees F.
- Step 4. Once the sprouts (purple or greenish) are about 2 inches long, cut the seed potatoes into sections with the healthiest sprout groupings.
You can often get 4 or more pieces to plant.
Enemy and Companion Plants for Growing Potatoes
All plants are unique, explaining why there are endangered tree species helping fight climate change. When growing together, companion plants live harmoniously and promote each other’s growth, while enemy plants are highly competitive and hinder the other crop’s well-being.
The best plants to grow near potatoes should help in pest control and yield increase, like beans, corn, thyme, parsnip, cabbage, and aubergines. On the contrary, the plants you don’t want growing near your potatoes include cucumbers, melons, tomatoes, courgettes, strawberries, pumpkins, and asparagus.
How Far Apart to Plant Potatoes?
Potatoes need sufficient room to spread; if you want a higher yield, you should leave out a massive space between each seed. Depending on the available area, you can plant them 10-18 inches apart in each column and 24-36 inches away in each row.
The potato spacing leaves room for the roots to extend and the trees to cast shades on the soil to reduce the temperatures, or the potatoes will rot.9
Common Pests of The Potatoes
Slight damage cannot affect potatoes when they are in great shape, but it is vital to seek natural and other control methods if severe. The following are the pests to look out for when growing potatoes.
Colorado Potato Beetles
These pests are infamous for attacking potatoes and other nightshade plants like peppers and tomatoes. They are black and oval-shaped, measuring about 9 mm long.
The female lays eggs underneath the leaves, and the larvae feed on the sap as they grow.
Flea Beetles
These tiny, elongated shiny 3 mm beetles are lethal to potato plants, causing massive damage, especially in large numbers. They leave holes in leaves and jump when the plant moves.
Wireworms
Wireworms are clicking beetle larvae that are yellowish-gray, measuring an inch long. They feed on all the parts of young potatoes, quickly sneaking into the wounds, and prefer invading when the soil is wet.
Natural Pest Control for Potatoes
Natural pest control is simple, effective, and preferably the first resolution when dealing with pests before opting for pesticides. To eliminate infestations, you can introduce insects that feed on the insects and not the plant.
For instance, praying mantis, spiders, and damsel bugs are excellent predators to feed on the Colorado beetles, while the braconid wasps and other nematodes can help control flea beetles. Biological control also works on wireworms, delicacies for various mammals and birds.
Common Diseases That Affect Potatoes
Potatoes are some of the most resilient crops but are still vulnerable to certain diseases like the following:
Early Blight
This disease is common in potatoes, usually manifesting as a tan or brown ring on the leaves. The spot spreads, eventually covering the leaf and causing it to wilt.
It travels through wind and water and can attach several plants at once.
Late Blight
Another dangerous disease to watch out for is late blight during wet seasons. It quickly eliminates the leaves and vines, hence the need to prevent it and remove any affected plant before it infects others.10
Verticillium Wilt
This fungal disease comes from the soil and transfers to other plants through the roots. You will notice the leaves turning yellow, brown, then dying, similar to early blight.
Potatoes
(Solanum tuberosum)
- Family: Solanaceae
- Growing Zone: Zones: 2 to 11
- Plant Type: Annual, Vegetable,
How To Stop Potatoes Disease
Besides knowing how to grow potatoes, it is also crucial to learn the most probable diseases and how to prevent them. Preventing potato blight is the first step because it is one of the most common diseases that spread quickly, simultaneously wiping out several plants.
First, always check that you are using disease-free seeds and keep rotating the potatoes yearly to grow them in different locations. It also helps to eliminate any affected plant immediately; otherwise, the fungus will spread, and you can use a fungicide spray if the case is severe.
The same preventive measures apply when dealing with Verticillium Wilt since it also spreads to other plants, making it challenging to recover an infected potato. To be safe, remove any plant at the first sign of the disease and avoid touching the plant until the soil dries.
Potatoes are fun and lucrative to grow, and it only takes a few simple steps. You can sow them in a container indoors or outdoors or go for conventional open-field gardening, where you can plant more simultaneously.
Luckily, the tubers are easy to care for, requiring up to six hours of sunlight, properly draining soil, and protection against bugs and diseases. Your crop should be ready for harvesting in 90-150 days, revealing several tubers per plant.
So if you’re looking for a great plant that yields delicious results, learning how to grow potatoes and how to plant potatoes is an excellent start
Frequently Asked Questions About How To Plant Potatoes
When Should You Harvest Potatoes?
