How To Prepare the Soil?
Preparing the soil for radish cultivation does not require much care, as the plant adapts to all types of soils.
The perfect soil for the growing radish should include deep, clayey, and neutral soils with a pH between 5.5 and 6.8. Learn more about How to Measure Soil pH.
Radish is a plant whose fruit are radishes that grow as roots and if the soil does not provide them with the required nutrients and good moisture then it cannot develop.
The soil for radish cultivation can be prepared in furrows with a distance of 6″ (15 centimeters) between them. The best soils are those containing decomposing organic matter.
About 20 million bacteria and a million fungi usually grow in a handful of soil. Radish requires soil that is free of weeds and undergrowth so that the plant can thrive and absorb all the nutrients it needs.
How Do We Water the Radish?
The radish requires specific care in terms of watering that has to do with maintaining uniform humidity, watering less frequently but thoroughly, watering always at dusk or early in the morning.
Always keep the leaves dry and apply the correct amount of water. The plant requires that the soil always remains moist, but be careful not to produce puddles,
Radish is more sensitive to lack of water than other root vegetable species and during the period close to maturity excess watering should be avoided because this could induce the plant to develop lateral roots.
In addition, if watering is in excess the radish may present diseases, such as rotting or the radish may break. On the contrary, if watering is scarce but its humidity is permanent, its flavor will be more pungent.
How Do We Grow a Radish Step by Step?
Radish can be grown directly from seed in a vegetable garden and does not require transplanting, so wherever it is sown it will develop and grow both in soil and in containers.
Growing Radish in Orchard
If the crop is grown in an orchard, it is recommended:
- Deposit the seeds in furrows 0.4″ to 0.8″ (1 to 2 centimeters) deep, separated by about 2″ (5 centimeters) from each other.
- Keep a distance between the furrows of approximately 2″ (5 centimeters) in case of sowing in more than one furrow. It is very important to respect these spaces so that the radish has a good root development.
- Water immediately after sowing, do not allow the soil to lose moisture.
How to Grow Radish in Pot
If you want to grow radish in a pot, follow the steps below:
- Select pots or containers with a depth of at least 6″ (15 centimeters) and a minimum volume of 33 liquid oz (1 liter).
- Use a substrate rich in nutrients and with good drainage.
- Sow the seeds in small furrows 0.4″ to 0.6″ (1-1.5 cm) deep and with a distance of 3″ to 5″ (8-12 cm) between them, depending on the size of the variety.
- Place the seeds 2″ (5 cm) apart and cover with soil and mix. If they are sown too close together, the radishes will be affected by the high temperatures, and their roots will not grow properly, also altering their flavor.
- Fertilize the radish 15 days after sowing to provide more nutrients and encourage its growth.
Radish seedlings will emerge approximately 3 days after sowing and the first leaves, cotyledons, will be heart-shaped.
Sometimes, it is necessary to cover the radishes with a little soil once they have grown a little so that they develop better. Always keep the soil free of weeds.
Association Favorable Radish
The association of compatible plant crops produces benefits concerning their separate cultivation, in addition to the use of light, water, and or nutrients.
There are no known favorable associations of radish cultivation with other species, however, this selection will correspond to the horticulturists and specialists in the area to obtain better results.
What Pests and Diseases Attack Radish?
Radish can suffer from diseases caused by overwatering that can lead to rotting and cracking of the radish.
Also, pests and especially aphids and larvae affect the crop. A heavy infestation of caterpillars can kill radish leaves in a couple of days.
In general, it is very important to check the radish crop, once or twice a week, especially the reverse side of the leaves to detect any pests that may present. To combat them, it is recommended to apply water with biodegradable soap or remove the caterpillars by hand.
To know if our radishes are ready, we must remove a little soil around the plant to check its size. To get them out of the ground we must take all the leaves and get our radish. If the soil is compressed it can take a bit of work, we can help ourselves with a transplanting shovel. Learn more about When to Harvest Radishes.
