When growing radishes the soil is an important factor. The plants need to be even and the same size. The soil has to be fine, permeable and airy. When it comes to irrigation, the soil must not be too compact and must not be worked with heavy machinery. We only use organic composts. Before sowing, the soil is ploughed to a depth of about 15 cm. After harvesting, the soil is then worked with a vibro to ventilate it.
Radishes are sown using a precision pneumatic planter to plant the seeds so that they are equidistant, according to the layout. The planting density will vary according to the time of year. At low temperatures and with plenty of light, the density will increase, while with high temperatures, the leaves will grow more quickly and therefore, the planting density needs to be lower.
IRRIGATION AND FERTILISATION
The soil is irrigated immediately after sowing. For good germination, the ground needs to be soaked evenly. The fertiliser is mixed with the water in set doses at this time. It is very important to water the seeds in the first week after planting and then to repeat irrigation only after the development of the bulb. It is not necessary to water much during the final growth stage as this will only boost leaf growth and encourage disease.
Radish plants need to be protected against soil fungi, other plants, and insects. The growing schedule needs to take into account any harmful pathogens so as to be able to intervene with treatments as little as possible. Everything is done with the right doses of water and organic fertiliser. The climate (temperature and humidity) influences radish growth a great deal, and regular checks are also important during growth. Animals and insects that easily attack radishes are: rodents, snails, slugs, cutworms, larvae of moths, leafminer fly, and mites.
