Did You Know?
1. Did you know that radishes are part of the same family as broccoli, cabbage, and kale? They all belong to the Brassicaceae family, also known as the mustard family.
2. Radishes were first cultivated thousands of years ago in ancient Egypt, and they were highly valued. Radishes were even used as currency and offered as gifts to the Egyptian pharaohs!
3. If you’re looking to speed up the growth of your radishes, try planting them alongside carrots. These two plants have a symbiotic relationship where the radishes help loosen the soil, making it easier for carrots to grow deeper roots.
4. Not only can you eat radishes, but you can also use them as natural dyes! The bright red variety of radish can be boiled to create a vibrant pink dye, perfect for coloring fabrics or even Easter eggs.
5. Ever wonder why radishes can sometimes taste spicy? The heat in radishes comes from a compound called allyl isothiocyanate, which is released when you bite into the vegetable. The intensity of the heat can vary depending on the variety and the age of the radish.
Growing Conditions For Radishes
Radishes are a versatile root vegetable that thrives in cooler conditions and is well-tolerant of cold weather. They do best in lighter, sandy, well-drained soils. Soil should be well-drained and slightly acidic to neutral, with a pH range of 6 to 7.
It is important to loosen the soil before planting, at least six inches deep, and up to a foot or more for long radish types.
To improve the quality of the soil, it is recommended to add well-rotted manure or compost. However, it is important to avoid using fresh manure as it may contain harmful bacteria and increase weed problems. Fertilizers containing weed killers should also be avoided as they can harm the radish plants.
Radish seeds should be planted directly into the loosened soil. Smaller varieties of radish seeds should be planted shallowly, approximately one-fourth to one-half inch deep, while larger varieties can be planted deeper, up to one inch deep. It is advisable to thin radishes to about two inches between plants for smaller varieties and four to six inches between plants for larger varieties.
Planting And Harvesting Radishes
The ideal time for planting radish seeds is from April through early May and again in August.
For daikon radishes, raised beds can be created to facilitate easier harvest. Planting should be done in rows approximately 20 cm apart.
Radishes have a short period from sowing to maturity and garden radishes are ready for harvest three to five weeks after planting. It is important to harvest them before they become fibrous and develop a strong taste. To harvest long daikon roots without breaking them, it is recommended to spade underneath the planting.
When harvesting radishes, it is advisable to remove the greens and wash the roots well before storage. Radishes can be sold in bunches or in bulk to prepackers. Daikon radish can also be processed for dried and pickled products.

Tips For Soil Preparation And Fertilization
To ensure the healthy growth of radishes, it is important to prepare the soil properly. Land preparation requires a fine, well-prepared seed bed. Adding well-rotted manure or compost to the soil can help build up its water-holding capacity and improve its quality.
It is recommended to apply 100 g/m2 of a 5:5:5 N:P:K fertilizer prior to sowing, but fertilizer should be applied according to a soil analysis to avoid excessive use. Liberal applications of animal manure are also beneficial for growing radishes.
The ideal pH range for radishes is slightly acid, but it should not fall below 5.5. Soils should also be well-drained to prevent waterlogging, which can lead to poor radish growth.
Irrigation And Weed Control For Radishes
Radishes require adequate watering to prevent drought stress, as it can affect the flavor and texture of the roots. If there is not enough rainfall, it is advisable to soak the soil thoroughly at least once a week, and more often for sandy soil. During warmer months, daily irrigation is recommended to ensure continuous growth.
Weed control is important to promote the healthy growth of radishes. While weed control is generally not a serious problem, using mulch and regular cultivation can help prevent weed growth. To control weeds, it is advisable to encourage weed seeds to germinate and use herbicides before planting radishes.
Pests, Diseases, And Storage Of Radishes
Radishes can be attacked by pests such as the cabbage white butterfly, aphids, and the diamondback moth. It is important to monitor for these pests and take appropriate measures to control them.
Diseases that can affect radishes include black rot and white rust. Proper crop rotation, practicing good hygiene, and monitoring for symptoms can help prevent the spread of diseases.
When it comes to storage, radishes should be harvested in the cool and stored at a temperature of 0°C and a relative humidity of 90% to prevent wilting. Daikon radishes can be stored for several months, while garden radishes are best consumed soon after harvest.
Tip: Radishes are cool-season crops that do best in cooler conditions and are tolerant of cold weather.
