Selecting the Right Radish Scraps

Here’s what you need to know about selecting the right radish scraps for replanting –

Firstly, you want to look for healthy and fresh scraps that are free from any signs of decay or damage. Make sure the scraps of radish are recently harvested, as older scraps may have a lower chance of regrowth.

When selecting radish scraps, look for those that have a healthy root system. The root system is crucial to the regrowth of your radish. That means avoiding scraps that have been broken or damaged during the harvesting process.

Grow Radish from Scraps – Method 1

When it comes to growing radishes from scraps, preparing the scraps for planting is an important step to ensure their successful growth. Here are some tips on how to prepare your radish scraps for planting –

Start by cutting off the tops of the radish. You can use a sharp knife or scissors to do this. Make sure to leave about 1-2 inches of the top of the radish intact.

Next, remove any remaining leaves on the radish. This will help the radish focus its energy on growing new roots and leaves rather than trying to support the existing foliage.

Find a sunny spot where you want to plant your radish scraps. Prepare the soil by digging a two-inch hole in the ground, and then place the root end of the radish into the hole. Cover the hole with soil, making sure to gently press down around the root to ensure it’s secure. 

When planting your radish scraps, make sure to space them out properly. Dig a row of holes, keeping at least two inches between each hole. If you’re planting multiple rows, make sure to space them at least 10 inches apart to allow for proper growth and development.

Radishes typically mature within a month of planting, but if the temperature is cooler than 50°F, it may take up to 50 days for them to mature.

Radishes grow best in cool temperatures, around 60-65°F. Avoid planting radish scraps during the hottest parts of the year and make sure to provide adequate shade during hot days.

However, radishes need plenty of sunlight to grow well. Make sure to place your container or pot in an area that receives at least 6 hours of sunlight per day.

Radishes benefit from regular fertilization. Apply a balanced fertilizer or compost tea once a week to help promote healthy growth and a strong root system.

Method 2

Get a radish and remove the stems and leaves. Next, take the radish and insert three toothpicks into it, then position the radish on the edge of a glass.

Pour water into the glass without filling it to the brim, making sure the top part of the radish is poking out of the water. Avoid completely submerging the radish as this will cause it to drown.

Place the glass in a sunny window and let it be. If the water level gets low, simply add more water. After about a week, you may start to see roots and leaves forming, which means that growth has begun. Allow the radish to continue growing in the water for about two weeks.

Once the radish has filled the entire glass with roots, it is time to transfer it to a flower pot. At this stage, the radish plant requires the nutrients that are present in the soil. Make sure to keep the plant in a warm and sunny spot, and water it as needed.

Harvesting and storage

Radishes are ready to harvest about 3-4 weeks after planting, depending on the variety and growing conditions. To check if your radishes are ready, gently brush away the soil around the base of the plant and look for a mature root. The root should be around 1 inch in diameter and be firm to the touch.

If you’re not sure whether your radishes are ready to harvest, you can also check the size of the plant’s top. If it’s about 2-3 inches tall, then your radishes are likely ready for harvest.

Now, grasp the greens at the base of the plant and gently pull upwards. The entire plant, including the root, should come out of the ground easily. Shake off any excess soil from the roots, but don’t wash them as this can lead to spoilage. 

Instead, store them as they are or wrap them in a damp paper towel to keep them moist.

Furthermore, freshly harvested radishes can be stored in the refrigerator for up to two weeks. 

Common Mistakes to Avoid When Growing Radishes from Scraps

Here are common Mistakes to Avoid When Growing Radishes from Scraps-

1. Choosing the Wrong Scraps

Not all radish scraps are created equal. Ensure that you choose scraps that are fresh and healthy. Avoid using scraps that are too small, too old, or have started to rot and have a yellowish colour. The ideal radish scrap is a root that is about 1 inch in diameter and has a healthy and firm texture.

2. Planting Too Deep

Radish should be planted about 1/4 to 1/2 inch deep in the soil. If you plant them too deep, they may not germinate properly and will not grow into healthy plants. Make sure that the soil is loose and well-drained to allow the roots to grow properly.

3. Overcrowding

Radishes need room to grow, so be sure to space them properly. To avoid overcrowding, plant radish seeds about 1 inch apart and thin out the seedlings to leave about 2-3 inches of space between the remaining plants.

4. Not Enough Water

Radishes need regular watering to grow properly, especially during the hot summer months. However, overwatering can also cause problems, such as rotting and disease. To avoid these issues, water your radishes regularly but not excessively.

5. Harvesting Too Late

Radishes are a fast-growing crop that matures in just 3-4 weeks. However, if you leave them in the ground too long, they will become woody, tough, and lose their flavour. To avoid this, check your radishes regularly and harvest them as soon as they mature.

By avoiding these common mistakes, you can grow healthy and delicious radishes from scraps in your own garden. 


Growing radishes from scraps is an easy and rewarding way to enjoy fresh, homegrown produce. By following the tips and guidelines mentioned earlier, you can avoid common mistakes and ensure a successful harvest.

Remember to choose the right scraps, prepare them properly, and plant them in well-draining soil in a sunny spot. Be mindful of watering and avoid overcrowding, and harvest your radishes when they are mature to enjoy their full flavor.

Give it a try and make your own radish from scraps.
