Geraniums are expensive! They can be found in most garden centers during the spring and early summer, but once the frosts come, they're done.
But wait a minute! They're perennials, which means they can live for a long time with the right care and conditions.
They can't take any frost, so indoors in a cool basement with some light, and only a little water. That can be difficult to supply, sometimes.
Wintering Geraniums upside down in brown
This method must be done
(I do it sometime mid October)
using this method it sometimes takes quite a while for the plant to begin to
grow, once you have planted it in the spring;
so you will need to decide when you have waited long enough.
For example……I have had plants that have
taken 5 weeks before they have shown any signs of new growth and sometimes when
I have gone to take the plants out of the bags they have already started to grow…..and
sometimes when I have planted a plant it has never grown.
this method is not my preferred method – but it does work. Probably 25% success rate.

Sometimes I have stapled the bag a few times to ensure that the plant
stays in the bag.

the bag – they must be exposed to the air.
find a cool, dry, dark place to hang the bag or bags.
They must not freeze (mine are between 4 – 12 degrees over the winter)
They must be hung away from light. My Mum used to hang them in a dark basement
so light is not important with this method.
About once a month go to each bag and spray the roots with water. Give them a good spray touching all sides of

into a protected area.

Wintering Geraniums in a Pot
This method must be done
(I do it sometime mid October)
This is my preferred method
From my experience plants
that are in bigger pots do better than the ones that are in smaller pots. The reason being is because smaller pots need
to be watered more often.
So if you have
pots that have only one geranium in them -
water them once a month.
pots with two or three geraniums in them can be watered approximately 3 times
from October to April.
Don’t over water!! Or the plants will rot.
I winter about 45-50 plants
(smile) so the larger quantity is reflected in my instructions.
Preparing my plants for the
winter is always a very sad day for me.
It just doesn’t seem right that I am putting them away in the basement
when they are absolutely
gorgeous!! But in order to
save them I have to prepare them well before any hint of frost.
Carry all pots close to where
you are going to store them.
best done outside as there is quite a bit of plant debris to be removed. I also stop watering my pots a week or two
before I plan to winterize them…..that way they are not so heavy to carry
when the time comes to prepare them for the winter.
Have a garbage bag ready
for all the flowers etc. you are going to remove.
If there are any visible
aphids you will want to remove them. (read
Label the pots so that you
know what colour geranium is in the pot.
Note: I have left
geraniums in their original pots and sometimes I have taken them out of one pot and put them in
another one. (Reason - I have large barrels so I need to take the geraniums
out of them and put them into something smaller.)
If you are taking geraniums out of one pot and putting it into
another – just prepare the new pot and then when you take the geranium out of
the old pot try to keep as much of the original dirt around the roots as

that might not yet have opened.
Now – carry your pots to
where you are going to store them over the winter. I have a basement with minimal heat and they
love it there. I also kept one plant in
my entrance way that has no heat register but there is light, and I have kept a
few in my kitchen. So depending on how
many plants you have will determine where you plan to store them over the
Place your pots in a lighted
area. Plants do not need direct sunlight
but they do need light.
The plants should be placed
in an area where the temperature is between 4 – 12 degrees. (they do best when
they are in a cool place but you can keep them in your house – they just get
very spindly )
Give each plant a good drink
of water so that it runs right through the pot.
From November to April I give
each large pot water 3 times and smaller pots with only one geranium I water
once a month. ** Remember don’t

You will be surprised at how
green the plants remain and also that they may even continue to bloom. The ones that I keep in my basement bloom all
In the spring when it is frost
free carry each pot outside and place
it in direct sunlight.
Give the plants water so it
runs right through.
Take each plant and cut it
back so that only 4” of plant remains. Everything
else gets cut away and all you have is the base of the plant remaining.
Each pot needs the top of the
soil turned or worked so that you can add Miracle-Gro
Shake ‘n Feed 12-4-8.
You may also need to add additional
potting soil so that the plants do not dry out as quickly over the summer. Also,
over the winter the soil tends to settle in the pot so make sure you loosen the
soil as deeply as you can without disturbing the roots.
Because the temperature is
still cool they don’t need a lot of watering so monitor watering yourself. I probably water every 3 weeks – just depends
on the weather.
I mentioned in the brown bag method *above* I have a long cement wall between my
cabin, and the lake I live on.
When I am
ready to plant my geraniums I prepare everything as I mentioned above and then
I leave my pots outside on the wall and let them get as much sun as they
can. I leave them on the wall until I
see they are well on their way with the first bloom showing.
Only after that do I start placing them in
different areas around the property.
Reason – I want them to get the best start they can – and the direct sunlight in the spring is what

ones you buy so be patient – when they do grow they are very strong and healthy
and it is so rewarding to see them come back to life.

Aphid treatment – I have used soap and water on my plants but it is not
Aphids are asexual which
means that you only need one aphid to reproduce more aphids so using the soap
and water method is really a shot in the dark because all you need to do is
miss one aphid and you have the same problem.
So a method I use is a follows:
Take your plant outside.
Get your garden hose and turn it on.
Hold your hand at the back of the plant so
when you are spraying the stock you do not bend it.
Spray the water on the plant with as much
force as you can from all angles. So in fact you are spraying with full force
water through the plant blasting
each stock where the aphids might be.
the winter some of my plants got aphids on them – so this past spring I did
this when I first put the plants outside, after I cut them back to 4”
Then a week later I did it
again. I never saw another aphid after
that. However keep your eyes open –
remember all it takes is one aphid.
If you have aphids on your
plants in the fall, I would do the same
Blast them with water full
force. Reason - the last thing you want
is aphids on your other indoor plants.
So if you are going to be bringing your geranium near other plants
perhaps have a little “incubation” area where you can watch them for a few
weeks. If they have aphids on them, you
either spray them or throw them away. The last thing you want is aphids on any
of your other plants.
Maybe your method for success will be slightly different, as we all have unique conditions, but this will give you some idea of what geraniums need.
Rosemary was the recipient of some of my geraniums at the end of the summer, and she set up her bright bedroom to be their home for the winter. Here are a couple of shots of the growing area - when the nights close in, she'll be installing some grow lights.
She's also trying to overwinter Nasturtiums and Lobelia - they may make a nice show for a while, but anything you bring in from outside must be treated for hitchhikers.
Rosemary (the plant) is a good candidate for overwintering too.
