White Icicle Radish Seeds
The White Icicle radishes have roots that are about 6 inches long, tapering like a carrot but are white and have a thin skin. This heirloom variety is not only tender and crisp but also packs a rich, spicy flavor, making it perfect for garnishes or salads. They typically take around 28 days to reach maturity.
While the exact origins of the White Icicle heirloom radishes are a bit of a mystery, they've been cultivated in the U.S. since the late 1800s. A seed catalog from 1903 referred to them as a bit of a novelty, and the 1924 Portland Seed Co. Catalog described the White Icicle radish as "This superb radish is the finest and longest of the very early, pure white varieties... their long, slender form and pure, paper-white skin are most attractive when bunched for market."
Start by directly sowing your first batch of radishes in nutrient-rich soil, roughly four weeks ahead of the last expected frost in spring. Plant them about 1/2" deep and 1" apart in well-prepared soil; later, thin the seedlings to 2-3" apart or more if you want bigger radishes. To keep the harvest going, sow a new batch every two weeks. Since most radishes don’t handle heat well, it’s a good idea to skip planting them during the hot midsummer months. For a fall harvest and winter storage, plant them about two months before the first anticipated frost in the fall.
Radishes thrive in consistently moist soil, especially when you add organic matter like compost. Make sure the soil doesn’t dry out, but be careful not to overwater, as that can lead to splitting.
You can harvest White Icicle radishes anytime up to their full length of 5". They taste best when they’re small, and the flavor gets milder as they grow larger.

Seed priming can enhance germination rates for White Icicle Radish seeds by soaking them in a solution that helps break dormancy and improve seedling vigor. For best results, soak the seeds in a mixture of 3% hydrogen peroxide and water before planting to promote quicker germination.
Seed Priming for White Icicle Radish Seeds
What is Seed Priming?
Seed priming is a method that boosts germination rates and the vigor of seedlings. It involves soaking seeds in a solution to prep them for sprouting. This approach can result in quicker and more consistent germination.
Recommended Priming Method
For White Icicle radish seeds, a typical priming method consists of these steps:
Soak in Hydrogen Peroxide:
Create a 50/50 blend of 3% hydrogen peroxide and water.
Soak the seeds for around 5 minutes.
Drain the seeds after soaking.
Use a Seed Germination Accelerator:
Combine the accelerator with distilled water as per the product guidelines.
Soak the seeds in this mixture for 12 hours.
Rinse the seeds before planting.
Benefits of Using a Seed Germination Accelerator
Faster Germination: Seeds can sprout up to 50% quicker.
Improved Seedling Health: Boosts the initial height and weight of seedlings.
Higher Survival Rates: Enhances the likelihood of successful growth.
Ideal Conditions for Germination
Temperature: White Icicle radish seeds germinate optimally at temperatures ranging from 45°F to 85°F.
Soil Moisture: Maintain the soil consistently moist but avoid waterlogging.
Sunlight: Plant in an area that gets full sunlight.
By applying seed priming techniques, you can greatly enhance the germination success of White Icicle radish seeds, resulting in a healthier and more fruitful crop.
