March is the month when the vegetable garden season really gets underway. Many gardeners start sowing seeds as early as the beginning of March. Temperatures are still low, but the soil is gradually warming up, the days are noticeably getting longer, and you can now sow a wide variety of crops indoors, in the greenhouse, and outdoors. So, in March, you can start preparing the vegetable garden. This March vegetable garden calendar will help you keep track: what can you sow now, what can you harvest fresh, and what should you take from your pantry?

Choose a dry time to loosen the soil and create fine seedbeds. Sometimes you need to wait until the open ground has warmed up sufficiently and is workable before sowing. Here, you can sow early carrots, radishes, spinach, and arugula directly into the open ground. Avoid sowing in soaking wet soil, as this will clog the seed furrows and hinder germination. When sowing small seeds, it's helpful to mix them with sand or dry soil for even distribution.
