A summer garden can certainly provide you with lots of fresh food. It’s fairly easy to grow food when the weather is warm and the days are long. But if you expand your horizons a bit, you can utilize that garden space all year. With a few tips and tricks, you can eat from the garden all winter. Even people who live in snow country can pull root crops and eat fresh salads in December. Here’s how to have a year round garden.
Start With a Plan
Spring and summer gardening can make us lazy – just scratch a few radishes or zucchini into the soil, water them in well and wait a few weeks. A year round garden takes a little more effort, starting with a good plan. Location is critical – you have to maximize the sunlight. A south-facing slope is ideal. Get rid of overhanging branches or anything else that might block sunlight. Second, remember that you will need to work a lot harder at keeping the soil in tip-top shape. You can’t plow in a green manure or mulch heavily and let things decompose over the winter when you’re trying to grow crops in the same space. Finally, choose your crops carefully. If you get hard freezes for extended periods, you need crops that can tolerate the cold. You should also think about how you will water if the pipes are frozen and how to protect crops from heavy snow or long periods of standing water.

Season Extenders
Back in the 1600s, some smart market gardeners in France began to use glass bell jars called cloches (pronounced cloa-shushes). These handy covers allowed them to start seeds earlier than usual and protect sensitive plants from frost. Those gardeners were also fond of cold frames and hot beds. The two structures are identical, but the latter has a layer of horse manure or compost in the bottom. As this bottom layer decomposes, it provides heat for winter crops and allows the gardener to start warm-season crops earlier. Modern gardeners may use row covers, high tunnels and greenhouses (fixed or movable) for the same purpose. Scott and Helen Nearing, who gardened in Maine, also used the thermal mass of rock walls in their greenhouses and enclosed gardens.
What to Grow
Summer garden planning is pretty easy – you grow warm-season plants. The rest of the year is a little trickier. In spring you have the option of harvesting crops you planted in late fall and wintered over; this group basically consists of brassicas, leafy greens and root crops. Examples: lettuce, kale, radishes, turnips, beets, parsnips, cabbage, chard and carrots. Don’t forget to plan for these in the summer garden as you have to get them in the ground and growing so they are mature enough to handle the cold. Fall is the time to finish harvesting the summer crops and to plant some quick-growing cool season stuff like bush snap or snow peas, radishes, lettuce, chard, carrots and spinach. And don’t forget to put in your garlic, potatoes and grains – they all do well (if not best) when planted in mid to late fall.
Varieties for the Year Round Garden
As long as you pay attention to maturity dates and day length, you should be able to grow pretty much anything. There are people in Alaska with year round gardens! Even your USDA zone is no more than a guideline, as you can create microclimates and use season extenders to get around possible zone limitations. For those in really cold areas, it’s important to pay attention to variety descriptions. For example, Winter Density is a truly cold-hardy romaine lettuce, while Buttercrunch can’t handle much more than a light frost. January King and Brunswick are particularly hardy cabbages. Almost any kale can handle snow and hard freezes. With root crops, the variety is less important than mulching; if your garden soil freezes hard you can’t get them out of the ground. Some leafy greens like chard may freeze back but will regrow as soon as the weather warms.

But It’s More Work!
A year round garden does mean year round work, but there are some “howevers.” However #1, many gardening systems require year round activity, some of it in large exhausting chunks. Think double digging, for example. With year round succession planting you may be able to skip double digging entirely (and I recommend you do!). However #2, the work is more evenly distributed. You aren’t scrambling to get your entire planting of broccoli in first thing so you can harvest and freeze before summer’s heat; you’ll eat most of it fresh from the garden. However #3, you may find you don’t need to do as much canning, freezing and drying in general. Your garden becomes an additional storage area. Don’t go overboard here, though – disasters happen. It’s probably reasonable to plan for half fresh and half stored. And hedge your bet with a few extras of each, just in case…
