Where to place your garden bed

A garden bed isn't a lawn decoration. It's an organic factory that converts water and sunlight into calories. Like any machine, if it doesn't get enough power, it doesn't work properly. Orienting your bed to receive maximum sunlight is a crucial component to a successful harvest.

In Southern Ontario, the sun is always in the southern half of the sky. In the winter it hugs the horizon, and in the summer makes wide overhead sweeps from east to west. You want to place your bed where it will get the most sun throughout the day.

Why sunlight matters.

Plants are essentially biological solar panels. They require a minimum "charge" to produce fruit.

Leafy Greens (Lettuce, Kale, Herbs): These are low-energy, cool weather plants. They can survive on 4 hours of direct sun.

Fruiting Crops (Tomatoes, Cucumbers, Zucchini): These are high-energy plants. They require a minimum of 6 to 8 hours of direct beam sunlight.

Where to put your bed.

South-Facing : This is the sweet spot. A bed with unobstructed southern exposure gets the most intense, consistent energy. This is where tomatoes and peppers belong.

West-Facing: The next best option. It gets the hot afternoon sun, which is great for summer crops, though you may need to water more often.

East-Facing: Good for cool-weather crops (lettuce, spinach, peas) that like the morning light but wilt in the afternoon heat.

North-Facing: The dead zone. Do not put a vegetable bed on the north side of a fence or building. It will be in the shade all day not generate enough energy to fruit.

How to orient your bed.

If you are installing a long, rectangular bed, the direction you point the bed matters. Ideally, you want to orient the long axis North-to-South, with the short ends pointed toward sunrise and sunset.

As the sun moves from East to West, it will shine down the "aisles" of your plants, giving both sides equal light. If you orient the bed East-to-West, the plants on the South side of the bed will grow tall and cast a shadow over the plants behind them on the North side, stunting their growth.

Test it yourself.

On a sunny day, go outside at 10:00 AM, 12:00 PM, and 4:00 PM and walk around your yard to see where the sun lands. If your desired spot is in the shadow of a maple tree for two of those three checks, you cannot grow tomatoes there. Pick somewhere sunny.

Make it convenient.

The further your garden is from your door, the less you will use it. Place the bed where you can see it while you wash dishes. If you see it, you will tend it.

Putting it close to a water source is also a good idea. The less you have to lug the hose or watering can the better.
