Step-by-step solution of how to plant radish
1, planted in spring or autumn.
Radishes can thrive in cold temperatures, so you should plant them when the soil temperature is still low. Spring radish, planted outdoors three weeks before the last forecast of frost. Autumn radish should be sown in midsummer, about two months before the first frost in winter.
When seeds germinate, the average soil temperature should be at least 40 degrees Fahrenheit (4 degrees Celsius), but the temperature of 50 to 70 degrees Fahrenheit (10 to 2 1 Celsius) will promote their maximum rapid growth.
2. Choose a good planting place
Radish thrives in sunny conditions, so if you choose more places, you should be able to receive at least six hours of direct sunlight every day. Ideally, you should also choose a place with loose soil and good drainage. You can improve the soil conditions when necessary, but starting with good soil conditions will make your work easier.
Also remember that radishes like soil with a pH of 6.5. Most soils are not too acidic or alkaline, so there is no need to do tests. However, if your radish is not planted well, you can consider taking samples to a nearby university, or going to a garden nursery or a home improvement shop to buy a household pH test kit to test the pH value of the soil.
3. Improve soil conditions
Loosen the soil from 12 to 15 inches (30 to 38 cm) with a rake or shovel, and then mix a layer of compost of 2 to 4 inches (5- 10 cm).
Step 4 spread seeds
Scatter the seeds as evenly as possible in the prepared soil. For spring radish, lightly cover the seeds with 1/4 inch (6 mm) thick soil, and for autumn radish, it is 0.5 inch (1.25 cm). You can also plant seeds in rows at intervals of 12 to 18 inches (30 to 45 cm).
After sowing, make sure they are watered evenly. Don't soak the seeds, because doing so will wash them out of the soil, but the soil surface should feel moist.
5. Ensure that the seedlings are not crowded.
When the height of the seedlings reaches 4 inches (10 cm), pull out the weakest ones to make the strongest ones have more space and resources. Early-maturing varieties will not be crowded at a spacing of 2 to 4 inches (5 to10cm), while standard or main varieties need a spacing of 6 inches (15cm).
