Growing Radishes
The fastest thing in the garden, seed to harvest in under a month.
How to Grow Radishes
Planting
Direct sow only, they don’t transplant. Thin crowded seedlings early or the roots stay skinny.
Watering & feeding
Keep the soil consistently moist, radishes that dry out and then get watered tend to split.
Harvest
Pull as soon as the shoulders show at the surface and look full-sized, don’t let them sit, radishes go pithy and hot fast in our heat.
Grows Well With
Plant radishes between slower crops like carrots or lettuce, they’re up and out before the neighbors need the room. See all our companion planting pairs →
When to Plant
Direct sow February through April, then again September through October. Radishes bolt fast in summer heat, so skip the hottest months entirely. See the full planting calendar →
