How to propagate Swiss Chard in the USA?

Swiss Chard is a leafy green vegetable plant related to beets and spinach. Swiss Chard can be propagated from seed or by division. 

  • To propagate from seed, sow the seeds in moistened potting mix or vermiculite. Cover the pot or container with plastic wrap to retain moisture and place it in a warm location. Keep the soil moist but not wet; the seeds will germinate within two weeks. Once the seedlings have two true leaves, they can be transplanted into individual pots or the garden.
  • To propagate by division, dig up an existing plant and divide the root ball into many sections using a sharp knife. Replant each section immediately in moistened soil or vermiculite at the same depth as it was growing. Water well and keep the soil moist until new growth appears.

Growing Swiss Chard from seed in the USA

  • The first step is to select the correct location. Swiss Chard prefers full sun and does well in partial shade. The soil should be well-drained and rich in organic matter.
  • Once you have chosen the perfect spot, it’s time to prepare the soil. Loosen the top few inches of soil and mix in some compost or other organic matter. This will help your Chard plants to thrive.
  • Now it’s time to sow your seeds. Sow them directly into the ground or seedling trays filled with potting mix. If sowing into trays, transplant the seedlings when they are big enough to handle (about 4-6 weeks).
  • Water your Chard plants regularly, especially during periods of hot weather. Add a layer of mulch around the Chard plants to help retain moisture.
  • Harvest your Chard leaves when they reach 8-10 inches in length. Cut them off at the base, being careful not to damage the plant itself. Swiss Chard leaves can be used fresh or cooked – enjoy.

Swiss Chard fertilizer requirements

Swiss Chard is a relatively low-maintenance crop, but fertilization is essential for optimal growth and yield. Swiss Chard requires high levels of nitrogen, phosphorus, and potassium. A complete fertilizer with a ratio of 10-10-10 or 12-12-12 is ideal. Apply fertilizer to the soil before planting and again when plants are 4-6 weeks old. Side dress with compost or manure every few weeks throughout the growing season.

Swiss Chard planting care in the USA

When it comes to Swiss Chard planting care, there are some essential tips to keep in mind. First, the soil should be loose and well-drained. Second, Chard can be propagated by seed, so if you’re starting from scratch, that’s the route you’ll want to take once the Chard seeds have germinated and thin them out so that only the strongest Chard plants remain. When it comes time to transplant the seedlings, do so with care – handle them gently so as not to damage the roots.

As for ongoing care, Swiss Chard is a relatively low-maintenance plant. Water it regularly (but don’t overdo it), and fertilize every few weeks during the plant growing season. If you live in a region with hot summers, provide some afternoon shade to prevent the leaves from wilting. Otherwise, sit back and enjoy the bounty of fresh greens.

Growing Chard in a raised bed

  • Growing Chard in a raised bed is a great way to start gardening. Chard is a hardy vegetable that can tolerate neglect, making it ideal for beginner gardeners. Raised beds offer several benefits for growing Chard, including good drainage, improved soil quality, and warmer temperatures in the spring.
  • When choosing a spot for your raised bed, ensure it gets 5 to 6 hours of sun per day. Chard likes well-drained soil that is rich in organic matter. You can improve your soil by adding compost or manure before planting.
  • To plant Chard, sow seeds directly in the soil in early spring or start seedlings indoors and transplant them later. Space plants are 12 inches apart, so they have room to grow. Water regularly and fertilize every few weeks with an all-purpose fertilizer to keep plants healthy and productive.
  • Chard is ready to harvest when the plant leaves are 4 to 6 inches long. Cut leaves outside the plant, leaving the inner leaves to grow. Chard will keep producing new leaves all season long if you keep harvesting them regularly.

Swiss Chard growing problems in the US

  • Swiss Chard is a popular leafy green vegetable, prized for its nutritional value and versatile flavor. However, Swiss Chard can be difficult to grow in the United States due to its sensitivity to temperature and soil conditions. 
  • One of the most common problems with growing Swiss Chard in the United States is that the plants bolt quickly in warm weather. Bolting is when a plant flowers and sets seed prematurely before the leaves are fully developed. This can happen if the plants are exposed to temperatures over 80 degrees Fahrenheit for extended periods. Once a plant bolts, it stops producing edible leaves and becomes bitter-tasting. To prevent bolting, choose a variety of Swiss Chard known to be heat-resistant, and make sure to plant it in an area that will stay cool during hot weather (such as in partial shade).
  • Another problem that can occur when growing Swiss Chard in the United States is poor germination rates. Many of the planted seeds will not sprout or produce viable plants. There are several reasons why this might happen, including incorrect planting depth, too much or too little water, or excessively cold or hot temperatures during germination. 

Water requirement for Swiss Chard plant growth

For Swiss Chard to grow properly, it needs water access. The amount of water required by the plant will depend on the climate and weather conditions. Swiss Chard plants generally need about 1 inch (2.5 cm) of water per week. More water may be needed during periods of drought or high temperatures.

It is essential to ensure that the soil around the plant is not allowed to dry out completely, as this can cause the Chard plant to wilt and die. If you are growing Swiss Chard in containers, check the soil moisture levels regularly and water as needed.

Swiss Chard pests, diseases, and their control

Swiss Chard is a versatile and nutritious leafy green and easy crop to grow in the USA. However, like all plants, it can be affected by pests and diseases. Here are some common Swiss Chard pests, diseases, and their control:

These small, sap-sucking insects can cause stunted growth and leaf deformities. They are also capable of transmitting plant viruses. To control aphids, try using an insecticidal soap or neem oil.


The cabbage looper and diamondback moth caterpillar can cause severe damage to Swiss Chard plants. Hand-pick caterpillars off of plants and destroy them. You can also use Bacillus thuringiensis (BT) to control caterpillars.

Flea beetles

These small black beetles jump when disturbed and feed on the leaves of Swiss Chard, causing small holes. Cover plants with floating row cover to prevent flea beetle damage in Chard plants. If flea beetles are already present, use an insecticide containing pyrethrin or Spinosad.

Diseases – Downy mildew

This fungal disease causes yellow color spots on leaf surfaces and white/gray mold on the undersides of leaves. It thrives in cool, wet weather. Destroy infected leaves and avoid overhead watering to prevent downy mildew from spreading.

Why is Swiss Chard not growing?

If your Swiss Chard is not growing, there are a few essential things you can do to troubleshoot. First, ensure you are planting in well-drained soil high in organic matter. Swiss Chard likes a lot of nitrogen, so if your soil is lacking, consider adding some compost or manure. You must also ensure you water regularly and evenly, as Swiss Chard will not tolerate drought. If you have been doing all these things and your Swiss Chard isn’t growing, it may be time to start from seed again.

When and how to harvest Swiss Chard?

  • Swiss Chard can be harvested as soon as the plant leaves are big enough to eat. Cut the leaves off at the plant base with a sharp knife to harvest. Swiss Chard leaves can be eaten fresh or cooked. The stalks can also be cooked and eaten but are often tough and stringy. If you plan to cook the stalks, it is best to peel them first.
  • Harvest Swiss Chard when the leaves are 6-8 inches long. Cut leaves with a sharp knife, leaving an inch or two of the plant stem. Swiss Chard can be harvested continuously throughout the growing season.
  • To extend the harvest, cut the leaves from the plant bottom first. This will encourage new growth from the top of the plant. Plants can be cut back several times during the growing season.
  • Swiss Chard yield in the United States varies by region and climate. In general, Swiss Chard grows best in cool weather season. The plants will bolt (go to seed) if exposed to too much heat. Swiss Chard planted in early spring or fall usually produces the best yields.
