Swiss chard, also known as chard, is renowned for its exceptional heat tolerance. Unlike other cooking greens, Swiss chard does not turn bitter in hot weather, making it a valuable addition to any summer garden. Its ability to thrive in high temperatures makes it a popular choice for gardeners in hot climates seeking resilient and flavorful greens. Furthermore, Swiss chard is packed with essential nutrients like vitamins A, K, and C, making it a nutritious and versatile leafy green to incorporate into your diet.
I first began growing chard while living in a hot summer climate, and was immediately charmed by its heat tolerance. Chard does not turn bitter in hot weather like other cooking greens tend to do, so it earns its space in the summer garden.
Can Swiss chard tolerate heat?
Yes, Swiss chard can tolerate heat. To grow Swiss chard successfully, harvest the leaves when the outer sets of true leaves are around 4 inches long. For larger, more mature leaves with a thick midrib, wait about 2 weeks. Harvest early in the morning for the best results.
Does Swiss chard grow all summer? Swiss chard does best in cool and mild weather but can tolerate some heat. Seeds sprout in soil temperatures ranging from 40–100°F (5–38°C), ideal at 86°F (30°C). Young plants can handle light frosts, and mature ones can withstand moderate frosts. To keep your Swiss chard growing throughout summer:
1. Plant in a spot with partial shade to protect from excessive heat.
2. Provide consistent moisture for healthy growth.
3. Harvest leaves regularly to encourage new growth.
How hot can Swiss chard tolerate?
Swiss chard prefers cool and mild weather but can tolerate some heat. Seeds germinate best at temperatures between 40–100°F (5–38°C), with the best range around 86°F (30°C). Seedlings can withstand light frosts, while mature plants are more resilient and can handle moderate frosts.
Can you eat chard after it bolts?
Yes, you can still eat chard after it bolts. When plants bolt in hot weather and start flowering, remove any flower stems formed, allowing the plants to continue producing edible leaves. However, once the flowering becomes prominent, it is advisable to remove the plants and compost them to maintain the quality of chard for consumption.
What temp is too hot for Swiss chard?
Swiss chard thrives in temperatures below 75°F; excessive heat can be detrimental to its growth. Young plants can withstand temperatures as low as 32°F without being significantly harmed.
1. High temperatures can cause Swiss chard to bolt prematurely, affecting the quality of the leaves.
2. Adequate moisture and partial shade can help mitigate heat stress on Swiss chard plants.
3. Consider planting Swiss chard during cooler seasons or providing shade cloth during hot periods to maintain optimal growing conditions.
Does Swiss chard do well in summer?
Swiss chard thrives in summer. If you notice holes or missing parts on the leaves, it may be due to chewing damage caused by beetles, caterpillars, earwigs, or slugs. To identify the exact culprit, look for specific evidence like droppings or chew marks left behind.
1. Look for small, round holes typically made by beetles.
2. If the edges of leaves are ragged, caterpillars might be to blame.
3. Earwigs leave irregular notches on the leaves.
4. Slugs leave distinctive slime trails near the damaged plants.
What to do with chard when it bolts?
When chard bolts, it is rare. Remove any bolted plants. Maintain moderate fertilizer and consistent moisture levels. Chard can handle some drying out but thrives best in evenly moist soil.
1. Trim bolted chard plants to encourage new growth.
2. Regularly check soil moisture levels to prevent under or over-watering.
3. Apply a balanced fertilizer to promote healthy growth.
4. Monitor for bolting signs in chard such as elongated stems and bitter taste in leaves.
Can you stop chard from bolting?
To prevent chard from bolting, opt for varieties like Ruby red and Rhubarb that are less prone to this issue. Bolting is more likely if chard is exposed to frost due to early planting, so wait until after the last frost to plant. Additionally, safeguard your chard from excessive heat and drought to further minimize the risk of bolting.
How do you keep Swiss chard from bolting?
To prevent Swiss chard from bolting, ensure the plant receives consistent moisture and avoid planting it in hot weather. Additionally, consider providing shade during peak sunlight hours and harvest the outer leaves regularly to encourage new growth and delay bolting. Applying a layer of mulch can help regulate soil temperature and moisture levels, further preventing premature bolting.
What does Swiss chard look like when it’s ready to harvest?
When Swiss chard is ready for harvest, the outer true leaves should be around 4 inches long. For larger, more mature leaves, wait an additional two weeks for a thick midrib. The ideal time to pick Swiss chard is in the early morning to ensure freshness and flavor.
Where is the best place to plant chard?
For chard planting, the best location is one that receives partial shade, especially in warmer climates. Additionally, ensure the soil is well-drained and rich in organic matter to promote healthy growth. To prevent bolting, it’s recommended to plant after the last frost and protect the plants from excessive heat and drought. Varieties like Ruby Red and Rhubarb are more prone to bolting if exposed to frost too early.
Can you plant chard in July?
Can you plant chard in July?

If Swiss chard is bolting, it is not typical. Remove any bolted plants and provide them with regular fertilizer and consistent moisture. While the plants can withstand some dryness, they thrive best in soil that is consistently moist. To prevent bolting in the future, ensure proper spacing between plants and harvest the leaves regularly to encourage new growth. Consider planting chard in partial shade to help prevent bolting during hot weather.
Is Swiss chard heat resistant?
What is Swiss Chard? Swiss Chard is a heat- and cold-tolerant leafy green in the beet family. “Essentially, it is the same plant as the beet,” Barbara Damrosch says in her excellent Garden Primer.
How do you grow Swiss chard in the summer? Water frequently enough to keep the soil moist. Weed aggressively. Spreading a 8 cm (3″) layer of mulch around your plants will help maintain soil moisture and curb weed growth. Mulch is especially important in warmer climates, as high summer temperatures and dry air encourages Swiss chard to go to seed.
In conclusion, Swiss chard is indeed a heat-tolerant vegetable that thrives in warm conditions. Whether grown in a garden or container, Swiss chard can withstand high temperatures and continue to produce flavorful, nutritious leaves throughout the summer months. By providing ample water and partial shade when the heat is intense, gardeners can ensure a bountiful harvest of this versatile and resilient leafy green. Incorporating Swiss chard into your garden not only adds beauty and diversity but also offers a satisfying and sustainable food source in hot weather, making it a valuable addition to any garden or kitchen.
