Radishes don’t play well with other plants. In general, they are best planted on their own or in a designated area of the garden. Radishes can be particularly aggressive and may crowd out other plants if they are not given enough space.

They also produce a lot of top growth, which can shade out other plants and prevent them from getting the sunlight they need. Radishes are also known to be heavy feeders, so they can compete with other plants for nutrients in the soil.

For these reasons, it’s best to avoid planting radishes with other vegetables or flowers. If you must plant them with other plants, make sure to give them plenty of space and don’t plant them in an area where other plants are already struggling.

Radishes also do well when planted with herbs, as the herbs will help to keep the radishes from becoming too aggressive.

Plants that don’t grow well with radish:

There are also plants that not ideally grow well with radish:

Beans & Peas

There are a few reasons why beans don’t grow well with radish. One reason is that radish release a chemical called “sinigrin” which can inhibit the growth of other plants. Radish also compete for the same resources as other vegetables, such as water and nutrients. This can again stunt the growth of other plants.


Radishes and carrots are both members of the cruciferous family, which means that they have similar nutrient needs. Radishes tend to need more nitrogen than carrots do, so if there is not enough nitrogen in the soil, the radishes will not thrive.

Radish and tomato companion planting

Radish is a great companion for tomatoes because it repels some common pests that can harm tomatoes, such as aphids and whitefly. Radishes also improve the soil quality in the area around the tomatoes, making them healthier and more productive.

When planting radish with tomatoes, it’s important to give the radishes plenty of space. Radish can also be planted around the edge of the tomato bed, as a border plant.

Cabbage and radish companion planting

Radish companion plants with cabbage can help to repel pests like aphids, cabbage worms, and flea beetles. Radishes planted near cabbage will also deter root maggots.

As you know, radishes are a fast maturing crop, so they can be planted near slower maturing crops like cabbage without the fear of the radish overshadowing the cabbage.

Radishes and cabbage also share some of the same pests, so companion planting them together can help to reduce the amount of pests that each crop has to deal with.

Another advantage to planting radishes near cabbage is that the radish greens can be harvested and eaten while the cabbage is still growing.

The cabbage will not be harmed by the radish greens being harvested, and in fact, the cabbage will benefit from the nitrogen that the radish leaves add to the soil.

Radishes are a cool weather crop, meaning they grow best when the temperature is between 60 and 70 degrees F (1).

Radishes are easy to grow and they need little care, as below:

1. Soil condition

Radishes like well-drained soil with high amounts of organic matter. The soil should be loose, light, and rich in nutrients. Radishes do not tolerate drought well, so make sure to keep the soil moist.

2. Planting

Radishes can be direct-seeded or started indoors and then transplanted outside. If you are direct-seeding, plant the seeds ½ inch deep and 1 inch apart in rows that are 12 inches apart. If you are transplanting, plant the seedlings 2 to 3 inches apart in rows that are 18 to 24 inches apart.

3. Watering

Water radishes regularly so that the soil stays moist but not soggy. Radishes will not tolerate drought well.

4. Season

Radish plants can be planted in the fall or early spring, as they can tolerate frost. In fact, radishes actually taste better when they are grown in cooler weather.

5. Fertilizing

Radishes do not require a lot of fertilizer, but they will benefit from a light application of compost or manure before planting. Side-dress radish plants with compost or manure when they are about 6 inches tall, and then again when they are in flower.

6. Weather

Radish plants do better when there is a consistent “chill” factor in their environment. This means that it should not get too hot or too cold for them.

When to Harvest Radishes

Radishes can be harvested any time after the roots have developed. The size of the root will determine how long you should wait to harvest.

For smaller radishes, you can harvest them as soon as they have reached a usable size. Larger radishes can be harvested when they are 1-2 inches in diameter.

To check if a radish is ready to harvest, gently push on the soil around the root. If it gives easily, then it is time to harvest.

If you are not sure when to harvest your radishes, you can always pull one up to check. Radishes that are ready to harvest will have a deep red color and will be firm to the touch.

If the radish is still white or green, it is not ready to harvest yet. Radishes that are left in the ground for too long will become woody and tough.

How to Harvest Radishes

The best way to harvest radishes is to use a sharp knife or garden shears to cut them off at the soil line. If you pull them out by hand, you may damage the roots and reduce the shelf life of the radishes.

Radishes are a cool-season crop that can be planted in early spring or late summer/early fall. They are usually ready to harvest in about 4-5 weeks (2). The size of the radish will vary depending on the variety, but they are typically harvested when they are around 1-2 inches in diameter.

To ensure the best flavor, it is important to harvest radishes before they get too large. If they get too big, they will become pithy and flavorless.

There are a few things to keep in mind when harvesting radishes:

  • Radishes can be harvested at different stages of maturity, depending on the desired use. For example, you can harvest them when they are small and crisp for eating raw, or wait until they are a little larger and milder for cooking.
  • Radishes will continue to grow after they are harvested, so you can leave some in the ground to mature if you want larger radishes.
  • Radishes can be stored in the refrigerator for up to 2 weeks.

Final Thought
