When to Grow

French Breakfast radishes are cool-season crops. You can begin sowing the seeds about 4 weeks before the last frost in the spring. These radishes thrive when the weather is cooler, ideally between 50-75 F. If temperatures are too high, the radishes may bolt and produce smaller, spicier roots​.

How to Sow and Plant

Direct sow French Breakfast radish seeds into well-drained, fertile soil about 1/4 inch deep and 2 inches apart in rows spaced 6 inches apart. Radishes do not transplant well, so it is best to plant them where they will grow.

How to Grow

These radishes need even moisture to develop crisp, flavorful roots. Water them regularly, aiming to keep the soil evenly moist but not waterlogged. Mulching can help retain soil moisture and suppress weeds. Radishes do not need much fertilizer, but incorporating organic matter such as compost into the soil before planting can improve growth​.

How to Save Seeds

  • Radishes are insect-pollinated, so you'll need to isolate varieties by up to 1⁄2 mile or stagger plantings to avoid flowering at the same time.
  • Staggering can be easy because of the radish's quick maturity.
  • Allow flower stalks to shoot up and seed pods to dry on the plant before picking pods and opening by hand to remove the seeds.
  • Seeds will remain viable for up to 5 years when stored in an airtight container.

FAQ

Can I grow French Breakfast radishes in containers?

Yes, these radishes can be grown successfully in containers. Use a container that is at least 6 inches deep, with well-draining soil. Keep the soil consistently moist and place the container in a location that receives full sun.

Why do French Breakfast radishes sometimes crack or split?

Cracking or splitting usually occurs when the radishes receive an uneven supply of water. A sudden influx of water after a dry period can cause the roots to swell rapidly and crack. To avoid this, make sure that the soil remains consistently moist throughout the growing season.

What are common pests that affect French Breakfast radishes, and how can they be managed?

These include flea beetles, which chew small holes in the leaves, and root maggots, which can damage the roots. To manage these pests, use floating row covers to protect young plants and practice crop rotation to reduce pest buildup in the soil. Maintaining good garden hygiene and removing plant debris can also help minimize pest issues.
