Just when you think spring can’t get any drier, 2023 arrives. It’s dry, hot, and windy. As I write this, heavy smoke is covering the sun. For many of our readers, the primary concern is not the garden but wildfires.
Planting seeds into soil that feels more like dust than soil is common here in Alberta. With over 300 days of sunshine a year, rainfall is scarce. Spring, however, often feels exceptionally dry. It seems we alternate between cold spring challenges and dry springs. In this article, we will share how we deal with the challenges of dry spring weather in the garden.
Challenges exist to be solved, not dwelled upon. We love our many sunny days and finding ways to still maintain a productive garden is inviting. We utilize the sunshine in our indoor garden to grow food year-round. In this article, let’s explore how to overcome the challenges posed by a dry spring.
Catch the snow and snowmelt
In a cold climate, the moisture we receive during frost comes in the form of snow, not rain. Our first rain might not arrive until as late as May. Between the last snow and the first rain, there can be a prolonged period without any moisture.
To avoid having bare, dry soil for as long as possible, we want to catch as much snow as we can in our garden. The longer the snow cover lasts, the better chance we have of avoiding very dry soil in spring.
The picture above shows how a simple palate fence holds back snow from blowing over the garden. A snow fence or shelter belt would have a similar effect.

Swells should also be mentioned in the same category for catching snowmelt. If your garden is on a slope, building some simple swells can make a difference by preventing the moisture from flowing away and allowing it to stay in the garden.
Between snowmelt and planting time, we often experience a few weeks of dry, cool weather. It is too cold to plant anything sensitive to frost, but greens, root vegetables, and onions can already be directly planted early. These plants can tolerate a bit of frost and will have a better start before it becomes too dry for germination.
We cover planting times in more detail in our article When to plant what. There are many good reasons to start planting as early as you can, and the dry spring challenge is one of them.
Spinach, for example, is best planted in the fall so that it can grow during the cooler spring days. Planting spinach during a dry spring does not yield good results.

Sprout seed before planting
Due to our short growing season, we start many seeds indoors. See here for a schedule of when and what to start indoors. Especially if you have no way to water the garden regularly, transplants can be a real help. They need watering too, but usually, a good soak at planting is sufficient.
In addition to starting seeds indoors, you can soak or sprout seeds before planting them in the garden. This way, the initial moisture they need will occur in a jar or sprouting tray.
We have also had good results with sowing carrot seeds in corn starch. This method not only helps to distribute them evenly, reducing the need for thinning but also provides moisture around the seeds.
Water the garden
To be able to water the garden, you need to have water available. Water is precious in dry climates, so having systems in place to preserve it is important.
We try not to water the garden excessively during the entire growing season. Instead, we prefer to use mulch. However, in spring, to germinate seeds and establish plants, we water the garden. With a water pump and a hose that reaches every corner of our garden, watering is not a huge task. Read more about watering the vegetable garden here.
However, we have to be mindful of our water usage. Even though we can store over 4000 liters (1056 gal) of rainwater, in some springs, we do run out of it.
Mulch the soil
Mulching greatly helps to conserve moisture in the soil. Natural materials like compost, straw, wood chips, grass clippings, etc. can be used as mulch.
Mulch cannot create moisture that isn’t there, but it can keep the soil moist for longer periods.
A no-till garden should always be mulched. Read more about maintaining a no-till garden here. Mulch can also be added after planting in a tilled garden.
Adjust the thickness of the mulch according to your weather conditions. If you cover dry soil with a thick layer of mulch that rainwater can’t penetrate, you are actually preventing moisture from reaching the soil. Loose straw or wood chips are good choices in this case.
Protect the garden from the wind
A dry spring is often accompanied by strong winds that further dry out the soil. A windbreak fence or hedge can help mitigate this. A windbreak provides up to 10 times the wind shelter (up to 20 times partial protection). A 4-foot-high wind barrier will protect 40 feet (approximately 12 meters) of gardening space.
During heavy spring winds, it can be challenging to keep the mulch in place. Use boards or fence posts to weigh down the mulch, as seen in the picture above. Once the potatoes planted there start growing, they will hold the mulch in place on their own.
Provide shade for the plants
Bright sunshine throughout the spring day is often too intense for young seedlings. Use a shade cloth or frost blanket to provide the necessary protection from the sun.
These blankets can also be left on not only for shading during the day but also to provide warmth to the plants during cool spring nights. It’s a win-win situation.
