Swiss chard generally grows to about 2 feet in height, and while it grows best with full sun, it can also handle part shade. Chard thrives in neutral soil with a pH between 6 and 8 but is tolerant of many soil types. Unlike many similar leafy greens, swiss chard isn’t sensitive to day length, providing one more reason to grow it year-round. It’s also relatively drought tolerant, though chard needs regular water to produce new leaves. If you’re growing your Swiss chard in containers, be sure to use well-draining potting soil with a high percentage of organic matter. Don’t be afraid to harvest Swiss chard from your containers- as long as you leave some of the plant, it will continue to grow.
One thing to consider when growing Swiss chard and other plants in winter containers is the type of pot or planter. Many popular materials for planters don’t handle repeated freezes and thaws well, and terracotta can even crack as a result. Fiberglass, stone, and heavy plastic are all good options for winter container gardens. Larger containers are best as the additional soil will provide your plants’ roots some protection from sudden temperature swings, as will a layer of mulch.
