Are you wondering if March is too early to start a garden? This post explains what plants can survive in the cold, what is a winter hardy plant, what are the easiest plants to grow in winter and more.

The ground is attempting to thaw, which means mud season has officially arrived and with it my itch to garden and grow has returned in earnest. I’ve just gotten my new elevated garden beds from Gardener’s Supply Co built over the old garden bed and spread a thick layer of clover seed beneath with dreams of a carpet of clover to rest on come warmer days and now I can’t think how I could wait another two months for our last frost to start planting them. So we’re going to plant out a small cold hardy garden in the first two beds here just to tide us over until we can start planting the majority of our crops in May.

This will be the smallest planting we do all year, and so I committed to really savoring the sensory experience of it and slowing down to enjoy the process. All I need to bring with me are my seeds, my favorite trowel and gloves. And I’ll be bundling up because while these plants I’m growing may be cold hardy, I most certainly am not! So sweaters and hats and layers galore. I love the lack of urgency and the sense of hope I get from planting the first cold hardy garden of the season. Soon green things will push up out of the earth and remind us that we are all connected to the life that grows beneath our feet.

We have a short growing season here in New England, but that won’t stop me from planting cold hardy vegetables that can thrive in these colder temperatures. My garden is just a few short steps from the back door, overlooking 70+ acres of my neighbors fields and surrounded by the buzz of life beginning to stir - a blue heron in the distance, a mouse skittering through the undergrowth.

Out back the trees are still in their deep sleep and the sun is trying its hardest to break through the seemingly endless layer of gray clouds that has graced the sky for the past four months now. I can still see my breath as I exhale, and this too is a reminder to be mindful. I breathe the same air as these trees that rest around me, and thank them for how clean and fresh it feels within my lungs. This grounds me in my purpose to bring myself and my body closer to the living things that are all around us.

What is a winter garden?

A winter garden is just a garden that you grow using only plants that can thrive in winter! There are many fun varieties of cold hardy vegetables and perennial plants that have unique characteristics that help them to survive in colder climates. For instance, kale, brussels sprouts and other brassica plants produce a form of antifreeze when exposed to cold temperatures that actually causes the plants to taste sweeter. I enjoy winter kale far more than summer kale - not to mention, there’s no cabbage moth pests in the winter chewing through every leaf before I have a chance to harvest it.

What plants can survive in the cold?

Now I’ll preface this by saying that what can grow in my garden in March may not be the same as what can grow in your garden. If you are in California for example I’m afraid this post won’t be much help to you as you do not suffer from the same deep cold winters we have here in the northeast. But in grow zone 6B many plants can survive the chill of late winter - as a matter of fact, some plants like lettuce and spinach require a colder temperature in order to germinate. This is why you’ll begin to see signs of life in the form of things like wild onion grass even this early in the season when the trees are still sleeping. And since we’re all about low-energy gardening tips and tricks here, I’ll also only focus on what is the easiest plants to grow in winter. No seed starting, forcing rhubarb or chilling your garlic seed in the freezer to trick it into sprouting earlier here. I want to focus just on plants that can go straight into the ground in March.

Winter plants for the garden:

Here is everything I will be planting in my cold hardy garden using my elevated beds from Gardener’s.

Snap peas (germination temp 40+ F)
Pansies (germination temp 45+F but we are planting these from established plants from the nursery not seeds)
Lettuce (germination temp 35+F)
Radish (germination temp 50+F)
Spinach (germination temp 40+F)
Chives (transplanting this from another spot, these grow well at temps above 40F)
Calendula (this one is more of an experiment as while it is cold-hardy once established, it probably won’t germinate until soil temps reach 60 degrees fahrenheit)

What is a winter hardy plant?

A winter hardy plant means any plant that can survive average winter temperatures, including cold hardy vegetables and cold hardy perennials. Most winter hardy plants do not produce much throughout the winter due to the lack of sunlight but by surviving these cold conditions they are able to establish themselves faster in the spring which means they will be the first to yield a harvest since they will mature before anything else in your garden.

What can I plant in pots for winter?

Some plants that won’t survive the winter outdoors can be transplanted into pots for the winter and brought indoors. You can do this successfully with most herbs including rosemary and sage. You can also overwinter pepper plants (which are perennial in warmer climates) by cutting off all of the foliage except for the main Y shaped stem, moving into pots and storing in your basement. They will go dormant and then can be transplanted back into your garden beds after your last frost date.

When I was deciding what to plant in early spring, I was happy that everything I wanted to grow would thrive in my elevated garden beds - which meant I didn’t have to worry about hurting my back while gardening. With my arthritis, it’s important that the way I garden is accessible and gentle on my body while still providing me with opportunities to stretch and strengthen my joints. I found prepping the elevated raised beds to be the easiest it has ever been, since I didn’t even need to weed the planting area prior to starting. It feels like a true luxury to stand over my raised beds in the garden and I was able to save more of my limited energy for actually enjoying being in the garden instead of just trying to finish as quickly as possible before my energy ran out. The beds are quite deep and so they can support the largest root structures of some of the plants I’ll be growing with no problem.

I had honestly begun to dread spring garden prep last year. I found myself crying in frustration more than once trying to wrangle the wildness of my in-ground beds into shape for planting. It is really shocking how much harder it is to work the earth when your back is in pain and your energy reserves are lower. While I do greatly appreciate the physical benefits of working out via the garden, and weeding has always been the best way to let out any pent up aggression, my body has been telling me for a couple of years now that this isn’t the right way to go about it for me anymore. I feel lighter knowing that I won’t have these dark moments in the garden where I really have to push myself beyond my limits anymore and can just be present and enjoy the process of gardening again. A part of me felt worried I wouldn’t be taken seriously as a gardener if the majority of my plants were grown in what is effectively a giant container garden. Especially with our full acre to work with, I knew I wanted to take a hybrid approach. So we have perennials like asparagus and rhubarb in-ground since those don’t require much maintenance year-to-year and then larger crops like garlic in ground as well. And of course borders of wildflowers fill up a lot of space too. Eventually it is my dream to add a greenhouse to carry us through the endless winters. But these elevated beds have taken such a weight off my shoulders (and my back!) and gave me back my peace in the garden, and I would not trade that feeling for anything.

If you’re looking for winter garden ideas, I hope that you’ve found this post helpful. Don’t forget to check out this post on cold frame gardening to extend your growing season even further + Let me know in the comments what you are planting in your winter garden this year.
