How To Garden In Winter Indoors And Outdoors

Learn how to garden in winter both indoors and outdoors, even if you live in a cold climate.

Just because it’s cold outside doesn’t mean you can’t grow vegetables.

In fact, some vegetables taste better when grown during the winter.

Growing a garden during the winter months is the best way to make sure that you have a sufficient supply of fresh vegetables ready to harvest even if it is the weather outside if frightful.

How To Garden In Winter Indoors

Most cold tolerant winter plants won’t mind the colder weather winter, however some varieties a little need extra protection from the cold weather to help them thrive..

It is possible to grow these plants in pots, boxes or grow bags indoors.

The best place to grow a winter garden indoors is a conservatory or in an unheated greenhouse, however if you don’t have access to either one, try a sunny window in your apartment or home. 

Or turn your basement into a grow room.

Some plants need more light than the winter sun can offer, even if you do have a greenhouse or conservatory, however it is easy enough to supplement natural light with grow lights.

For those growing in a basement or indoors, the addition of a grow light or two is necessary to keep the plants producing.

Here are some of the vegetables that require a minimum amount of light to give you prolific harvest and do not need a large growing area.

Carrots And Radishes

Both carrots and radish grow well in boxes, pans and pots when planted in well-draining soil.

Carrots can grow a lot longer than a radish, so to prevent a possible issue with your container not being deep enough, choose a smaller, round variety of carrot such as Romeo.

Make sure the container of radishes or carrots receive at least four to five hours of sunlight or its grow light equivalent each day so the plants develop properly.

Sow seeds for both of these plants from early fall through late winter.

Most varieties of radish are ready to harvest 21 to 25 days after planting.

Carrots need a longer growing time and often are not ready to harvest until two to four months after being planted.

For those who want to grow carrots and radish over the winter, but do not want to grow them indoors, it is possible to grow both carrots and radish outdoors inside of a cold frame during the winter months. 

Beans And Peas

Seeds of beans and peas are easy to grow in pots provided you have some type of trellis for the vines to grow on. 

Bush beans are the best choice to grow indoors, but be aware, even bush beans will vine if given the chance.

Peas prefer cooler temperatures, so grow these in a cooler area indoors.

Both of these plants must flower before they are able to produce and they do self pollinate.

The amount of time from planting to harvest varies depending on the variety.

A typical time frame is two to three months after planting.

Mushrooms

Growing mushrooms year round is very easy.

For those who are new to growing mushrooms, start with a ready-made mushroom growing kit.

However, if you are an experienced grower, you can prepare your own bags or make a special compost bed and plant the mushroom sprawn.

Whatever method you use, water the medium well and kept the container in a cool, dark place.

The ideal temperature for mushrooms to fully develop is 50 to 60 degrees Fahrenheit.

The best place to grow mushrooms indoors in the winter is a basement if you have one in your home.

Potatoes

For those without outdoor growing space, potatoes can be grown indoors in sacks or large pots.

Fill pots with compost and well-draining potting mix, then plant the sprouted tubers.

Provide the growing potatoes with five to six hours of sunlight a day or its equivalent in grow light to have successful yield.

For those who do have outdoor growing space, planting potatoes in late summer or even as late as the last week in December is a better option.

To grow potatoes over the winter it is important to make sure they are planted deep enough.

Here is how to do that.

1. Dig a trench two shovel blades deep.
2. Place an inch of dried leaves, straw from a chicken coop or goat stall or dried grass in the bottom of the trench.
3. Place the sprouted potatoes on top of the dried material.
4. Cover them completely with more of the dry material.
5. Place an inch or two of soil on top of the dried material.
6. Cover the top of the trench with row cover or plastic making sure to place blocks, bricks or other material on top of the row cover or plastic so it does not blow away.
7. Check the potatoes from time to time and once you see new growth, cover that growth with soil. It is very important to keep potatoes growing under the soils surface. 
8. Once the potatoes start to flower you can either let them flower, allow the vines to die back and then harvest the potatoes or cut the flowers off and keep them growing until they flower for a second time. Once they have flowered twice, let them complete their life cycle and harvest the potatoes.

Potatoes planted in late summer or early fall might be ready to harvest sometime during late winter, depending on how much they grew.

Potatoes planted by the end of December are ready to harvest at the end of May or the first of June.

How To Garden In Winter Outdoors

Growing plants outdoors during winter is a bit challenging but it is possible.

It is important to read the seed packages carefully and choose varieties that are cold-tolerant.

One of my favorite places to find varieties that are ideal for winter growing is Johnny’s Selected Seeds.

Once I buy the seeds and figure out which ones thrive in my area, I allow those plants to go to seed the following year and harvest the seeds.

This helps me make sure I am growing varieties that do well in my garden during the winter months.

The reason for this is because these varieties have survived, adapted to the local environmental conditions and survived any potential pests that managed to survive the winter weather here.

It is important to purchase heirloom, open pollinated seeds, however because it is against the law to save seeds from any type of GMO seeds.

It is also important to note that saving seeds from hybrids does not guarantee the plants you grow the next time are going to be the same.

Here are some examples:

Onions

This is considered the most resilient type of vegetables because most varieties can withstand temperatures of -64 degrees Fahrenheit.

Onions also  thrive in less than ideal growing conditions.

In my high tunnel I have forgotten to harvest the onions, left them in the ground all summer and had them return the following fall.

Chervil And Oregano

These herbs prefer cooler weather and can easily withstand winter frost.

Chervil is used as garnish for variety of salads while oregano is used as a spice, especially in Italian foods.

Of course, these are not the only herbs that continue to grow outdoors during the winter months. 

I have seen cilantro, celery leaf, mint and many other herbs last well into the winter without protection.

Salad Greens

Lettuce is one of the easiest winter crops to grow inside a cold frame or high tunnel.

It is tender and flavorful with no bitterness at all.

Other types of leafy vegetables that do well in the winter garden include endives, golden purslane, land cress, Swiss chard and mizuna greens.

It is important to cover the salad greens with row covers even though the crops are being grown inside a cold frame of high tunnel.

Make sure the row cover does not touch the plant material though.

It is best to wait until sometime between 1pm and 3pm to open the cold frame to harvest the salad greens.

The reason for this is if you try to harvest the salad greens too early in the morning they will appear to be damaged by frost.

Once the temperatures inside the cold frame or high tunnel heat up, the salad greens spring back to life.

If you wait too late in the day to harvest your crops, the heat inside the cold frame or tunnel house escapes and then it is hard for nature to quickly replenish that heat to keep the crops warm through the night.

Final Thoughts About How To Garden In Winter

Gardening in the winter is something I really enjoy even though I don’t care for the colder weather or the snow.

Nothing compares to walking into a high tunnel to harvest growing vegetables when there is snow on the ground outside.

Of course, I have also grown many vegetable plants in pots indoors even when I lived in an apartment.

It takes patience and work, but it is doable.

This is a great way to save money on your winter grocery bill as well.

I hope you will give it a try and let me know how it turned out.
