When to Plant Swiss Chard Seeds
The best way to start many plants is to grow them from seeds indoors before the last frost to give your garden a head start and ensure the plants thrive once you take them outdoors.
Here is when to plant Swiss chard seeds or planting beets from seeds to prepare them for the garden or pot.
If you’re wondering when to plant Swiss chard in zone 5 and up, consider starting them inside about three to four weeks before the last frost date to give them a head start.
Soak the seeds 24-hours before planting for faster germination. Fill a seed starting tray with potting soil and sow seeds a half-inch to three-quarters of an inch deep in the soil and four to eight inches apart.
Water them to help the dirt settle and place the tray on a sunny windowsill. If you do not have a window with good sunlight, set the tray near a grow light or bright lights to encourage germination.
When to Plant Swiss Chard Outdoors
After your plants germinate and reach a healthy size, it’s time to transplant them outside into a different container or garden bed. While this process is fairly easy, take some steps to ensure your plants adjust to the change and thrive.
If you’re wondering when to plant Swiss chard in zone 6, it’s safe to sow the seeds directly in the garden or container two weeks before the last frost or in the late summer for a fall crop.
However, it’s best to wait until early spring, when the temperatures are steady if you plan on planting seedlings.
Once the plants are four weeks old, harden them off by acclimating them to the outdoors. Take the young plants outside a couple of hours each day for about a week to help them get used to the changing temperatures.
Prepare the garden bed or raised bed with organically rich soil or fill a 12-inch deep patio pot with potting mix. Choose a spot in your yard or porch where the Swiss chard receives full sun for part of the day.
Make holes 12 to 18 inches apart in the dirt with 12-inch spacing, ensuring they are larger than the plant’s base. Remove the seedling carefully and transplant it into the bed.
Push soil around the plant and pat it down gently with your hands. Finally, water the garden thoroughly to help the plant’s roots settle into the dirt.
Swiss Chard Growing Season and Caring for Your Plants
Swiss chard growing season is different from many other garden plants since this leafy green is a biennial. Learn the best time to plant Swiss chard and how to care for your plants throughout the season to ensure you get the most out of your garden.
Swiss chard is annual and biennial. This means that it doesn’t go to seed during the first growing season, dies back when it freezes, and then returns from the root the following year. At the end of the second year, it grows a flower stalk, goes to seed, and dies.
Swiss chard grows fastest in cooler regions. If you live in a warmer area and wonder when to plant Swiss chard in zone 7 and up, the seeds grow well if you plant them directly in the garden ten weeks before the final frost.
The plants require about an inch to an inch and a half of water each week, so water your garden when your area lacks rainfall. They tolerate partial shade, but it’s a good idea to plant them in an area where they receive some full sun during the day.
Laying mulch over the dirt is a great way to help retain moisture while keeping the weeds at bay. Swiss chard does grow in poor soil, but applying nitrogen fertilizer, organic matter, or bone meal after planting encourages healthy leaf growth.
Consider covering your plants with a row cover to protect them from leaf miners or a light frost. For getting rid of aphids on Swiss chard and kale, use diatomaceous earth or a neem oil spray.
When is Swiss Chard Ready for Harvesting?

Swiss Chard Harvest
The length of time it takes for Swiss chard to reach maturity varies depending on the type, but the general time frame is 50 to 60 days. It’s safe to harvest the chard leaves at any time during the growing season, as long as they are large enough to eat.
