There was an old belief amongst the Pennsylvania Dutch community that St. Gertrude’s Day—known as St. Patrick’s Day today—was the official potato-planting day. They might have been on to something, as March offers the ideal conditions to plant these cold-loving crops. Start by planting seed potato pieces in trenches about 3 to 4 inches into the soil. Once a seedling has sprouted, cover the plant once again with 3 inches of soil and repeat a few weeks later. This technique is known as "hilling," and it protects the tubers from sun damage.

A sweet and mild member of the onion family, leeks thrive in cool weather and can withstand unexpected frosts during the month. For happy and flavorful leeks, check that the soil is constantly moist. You may have to water the leeks once a week if you live in a dry climate with a lot of sunshine. The best part of growing leeks is that you can harvest them whenever they reach your ideal size for cooking.

It may come as no surprise that tomatoes are the most popular vegetable to grow in gardens at home. With so many colors and varieties, the possibilities are truly endless.

For best results, start from seed indoors 6 to 8 weeks before the last frost in preparation to transfer outside once the cold weather has passed.

Often referred to as a fall vegetable, certain quick-growing varieties of broccoli can actually be planted in late winter as the temperature begin to rise for a summer harvest. Plant these sun-loving crops in a spot in your garden that receives at least 6 hours of direct light. When it comes time to harvest, make sure the head is fully developed but hasn't produced any small yellow flowers yet.

March or early spring is an ideal time to plant roses, especially bare-root roses, which are typically only available in early spring. You'll want to make sure to wait until after the last frost.

While it's slightly preferred to plant this flowering shrub in fall, azaleas can also be planted in spring after the last frost. You'll want to space azaleas 2 to 6 feet apart, depending on their size, and plant where they will receive at least six hours of full sun. It's also important to plant new plants so that their top roots are at soil level or just below to avoid root rot.
