How to grow Potatoes In Containers - Complete Growing Guide


well everyone welcome to another very

exciting episode right here on the on my

gardener Channel I'm really excited for

this episode because in this episode

we're going to be talking about how to

grow potatoes in containers it's going

to be a continuation of our container

growing guide series and I really do

hope you're going to enjoy this one

because it's definitely been one of the

most highly requested growing guides for

containers that we've ever had so let's

get right into it

the first tip to getting successful

potatoes is obviously the elephant in

the room seed potatoes here we have some

seed potatoes that we did ourselves we

do have a video on how to make your own

seed potatoes it's quite simple but it

is definitely something that you're

going to want either purchase certified

seed potatoes or make your own seed

potatoes we've just taken our potatoes

that we harvested last year and we

stored them in a five-gallon bucket with

some sand and a tiny bit of moisture

they don't like to be exposed to air

otherwise they'll start sprouting if you

keep them cold throughout winter in a

bucket of sand you'll you'll have very

very small eyes and that is the ticket

to having great seed potatoes so we're

gonna be using our own seed potatoes but

just make sure you don't get them from

the store if you get just regular

store-bought potatoes that you know

you'd be eating that are not seed


they've been sprayed with a sprout

inhibitor and that keeps the the eyes

from forming and you will find that even

though they do form eyes eventually once

you put those in the ground they just

don't form good potatoes your best tip

for success is to get some seed potatoes

now the next thing that you're going to

need is the container since this is a

container growing guide container is the

Prophet I mean aside from the fact that

the seed potatoes are the most important

I would say containers are the next most

important because if you have too small

of a container you're just not going to

have good luck you want to keep

depending on how many plants you want to

grow per container you want to keep it

at a minimum of of 5 gallons and you can

go on up from there I typically get go

no more than 10 gallons and I can get 3

plants in this 10 gallon container here

because of the fact that when you're

moving around containers or at the end

of the season you have to harvest the

potatoes you have to dump them out and

things like that you get to be pretty

heavy to lug around and so I found a 10

gallon container is very manageable for

me and that's why I go to them no more

than a maximum of 10 gallons now the

next tip to having success

full potatoes and containers is the soil

the soil could not be more important

potatoes are a crop that really needs

good root development because they are a

tuber they need to be able to put their

roots down throughout the soil so that

they have room to set tubers if the soil

gets compacted you'll find that your

potatoes will be much smaller or almost

non-existent because if soil compact it

takes all the air out of the soil and

that actually will compress things down

that's a lot that's a big reason why

gardeners don't have nice size potatoes

is they just have too hard too much

compaction in their soil and it gets too

hard over time another thing that does

is it doesn't drain well as we talked

about with containers the container type

definitely can help you out also with

the right type of soil you want to be

able to drain freely so as you can see

here in our soil our soil is very loose

it is very rich in organic matter and

it's something you can compress but it

breaks apart

it also has perlite in it and that's

because we are using actually uh it's

per its pro mix that we've used from

last year and pro mix is mostly spagett

and peat moss and as it breaks down it

creates a beautiful rich compost but it

still retains a lot of its texture that

made it great in the first place so we

are actually recycling a lot of our soil

from last year and that's something that

you can do with potatoes a lot of times

people are always worried about potatoes

you always want to change out the soil

year after year and that's true to a

certain extent if you have disease if

you don't have disease on your potatoes

and they stay very healthy you can reuse

your soil year after year and we do and

we just keep it we just keep it in a in

a bucket and then we just use it in our

containers year after year or we'll

throw it on our beds and top it off the

fertilizer we're using is trifecta plus

it is our all-purpose fertilizer of

choice and it's been that way for many

many years now it is just a great once

and done all-purpose fertilizer if you

happen to go in trifecta plus you won't

really need to worry about any specific

nutrients but if you do go with

something else you need to make sure

that you put a good amount of potassium

in your soil potassium is the most

crucial component to having successful

potatoes you can worry about the

nitrogen you can worry about the

phosphorus but at the end of the day it

is actually been found in studies that


is the is the nutrient of choice for

potatoes they will actually do better

with more potassium in their soil in

fact a recent study was done testing out

different amounts of potassium in the

soil and found that when when nitrogen

phosphorous remain the same they remain

constant the only thing that increased

production in potatoes was the potassium

levels so make sure that you add a lot

of potassium in your soil it's going to

help with plant health it's going to

help with tuber development and it is

going to help keep the plant growing

nice and strong throughout the season

stress free because that's what

potassium does so what we're going to be

doing is we're going to be adding it to

this soil in a five-gallon container

with trifecta obviously it'll be varying

by how much you're going to add but for

potatoes they are very heavy feeders we

want to add about 1/2 a cup to a cup

depending on how many plants you have

we're gonna put a half a cup in our five

gallon containers and that's good for

the entire season and you can you can

reapply if you feel like it's needed as

well but for us we're gonna put a half a

cup and that's usually fine for the

whole season in our five gallon

containers and in our 10 gallon

containers we're going to use a cup of

fertilizer and that's just based on the

volume of soil that's in your beds okay

so we got our soil in here about three

or four inches deep and the next thing

we're going to do is we're going to

fertilize this you want to fertilize

right where the potatoes are going to be

not above the plant not below the plant

but right where the potatoes are going

to be because that's where the roots

begin to form and that's where they want

the most nutrients so we're going to

take our trek back to plus and we're

going to simply put in about a cup for

this ten gallon container here and then

we're simply going to work it in now you

will notice that trifecta plus has some

soil some are some some pelletized

sulfur and you probably saw that on the

surface of the soil there and it's just

characterized by these little yellow

almost like little yellow disks this is

paula ties sulfur you can get it at any

hardware store or any you know garden

center will have pelletized sulfur it

does have some in there as you probably

saw but we need to add a little bit more

for potatoes because potatoes prefer a

pH that is more acidic than any other

vegetable in the garden like tomatoes

they like a pH of around 6.5 slightly

acidic potatoes they need a pH of around


rent scab scab is actually a disease

that is caused from from to alkaline of

pH even if the soil has a pH of 7 that

is too alkaline even though by our

standards is considered neutral pH is

not even really alkaline there's just

not enough acidity in the soil to

prevent that scab and so by by adding

about 2 tablespoons of pelletized sulfur

here it's a it's an organic soil

amendment you're going to lower the pH

there of the soil to right around 5.5

and that's going to be great for for the

potatoes and they're also going to be

able to uptake nutrients better because

when the pH is ideal the plant can

uptake nutrients at its ideal rate so

the next we're going to do is we're

going to plant our potatoes now that

we've gotten the fertilizer and the

sulfur incorporated in we're going to

add our our seed potatoes here we prefer

to grow as a seed potato that has two or

three eyes per plant and we're going to

just set them right on top of the soil

surface now what we're going to do is a

little counterintuitive it's a little

different than growing in ground

typically you would Hill them very


however when we're growing in this

method we're going to Hill all at once

because we don't have the luxury of

being able to Hill up in a container

we're just going to fill the container

up at its top level and because these

potatoes are going to be down in our

container about four or five inches

below soil level it's going to allow the

plants to grow up and any root

development will occur down here

underneath the soil underneath the soil

level and that's going to keep potatoes

from coming up and being exposed to

sunlight and it's also going to allow a

lot of room for root development and

more tuber development so all we're

going to do is just take some fresh soil

and throw it on top I'm have to grab a

little bit more to fill up our pots but

we'll be done some final tips for

success with growing potatoes is

watering and sunlight so the sunlight

that these potatoes need to receive is

full Sun we make sure that when they're

out on our patio here we make sure that

they get around ten hours of full Sun

they will love ten hours they'll do fine

with around seven or eight but the more

Sun you can give them the better because

they're going to create more energy with

those leaves

meaning larger tubers and more of them

for you so we give them around ten hours

of Sun a full sun exposure is great you

don't have to

worry about them scorching or anything

in these pots they're large enough to

where the soil is going to stay cool

even in the hot or summer days and that

does leave me to Moya to moisture or

watering you want to make sure because

they are prone to root rot and to

Barratt you do want to make sure that

you keep them well watered but only when

they really need it what we'll typically

do is we will dig down about two inches

if it feels damp we'll cover it back up

and we'll leave it if it seems dry or if

the soil is quite dry and separating

from the edges of the container we'll

give it a really good watering and that

just makes sure the plant stays moist

because if the if the water goes or if

the soil goes very dry and it's lacking

too much water the plants become

stressed and the tubers will then become

smaller because the plants are actually

using up some of the water reserves in

the potatoes so you want to make sure

that you do keep them damp but not too

damp that it causes rot and that's

really all there is to growing potatoes

they're a very fun plant to grow I wish

you the best of luck with growing them

and let me know in the comments box

below if you if you are deciding to grow

them this year for the first time and

let me know also how it turns out
