Start With Good Seeds

Daikon is a biennial vegetable, which means it is grown as a vegetable in the first year and as an annual in the second year. This means that the seeds must be planted in the spring, when they sprout. as with all seeds, start with the best. the seeds you choose for daikon should be the variety “大黒”, or “ogon”. these seeds are the most widely used in asia, and are of a good quality. choose good seeds with an even color and shape. they should also be free from any damage. next, you want to store your seeds in an airtight container. this will help ensure that the seeds stay viable, and do not go bad.

Choose A Warm, Sunny Spot

daikon is a cold tolerant vegetable, which means it can withstand temperatures as low as 4 degrees celsius. if you live in a warmer climate, this might not be a problem for you. if you live in a cooler region, on the other hand, you need to choose a spot that is warm enough for daikon to survive. this means a spot with temperatures ranging from 11 to 17 degrees celsius. if you have a sunny spot that is warm enough for daikon, that’s even better. a sunny spot is best as daikon likes a lot of sunlight. as daikon prefers full sun, it is a good idea to choose a spot that receives a lot of sun. it’s also a good idea to choose a spot that is away from trees as they can provide shade that daikon doesn’t like.

Dig A Trench And Line It With Plastic

daikon likes to grow in deep, well-drained soil. in order to make the soil suitable for daikon, you need to dig a trench that is about three times the height of the daikon. mix a generous amount of manure with the soil to increase its fertility. if you have a sunny spot, you may also find it helpful to line the trench with plastic. this not only keeps the soil from washing away, it also keeps it from getting too warm as the plastic reflects the sun’s heat.

Plant The Daikon Seedlings

daikon seedlings are very delicate, and are susceptible to damage from even the slightest breeze. to protect them from the wind, you need to bury the seedlings in the soil. you can either do this yourself or hire a gardener. if you’re digging your own trench, you can lay the daikon seedlings on top of the soil. cover the roots with soil, and then gently tamp down the soil with your foot to keep them secure.

Protect From Cold And Drying Winds

daikon loves full sun, and therefore needs a lot of heat to grow. if you live in a cold region, however, you’ll need to provide your daikon with a heated greenhouse. in order to protect your daikon from freezing temperatures, you need to construct a windbreak. a windbreak is a low fence that blocks the wind from blowing towards the vegetable plants. you can either build a low fence or wrap the whole area with a windbreak cover.

Harvest The Daikon Crop Regularly

like all stored vegetable crops, daikon must be harvested regularly. if you wait too long between harvests, the seeds will begin to sprout. this means that you will have to start over from the beginning. a good rule of thumb is to harvest your daikon once a week. this will ensure that the vegetable keeps fresh for as long as possible. you can either do this manually, or you can use a daikon harvester.

Dry The Daikon For Storage Or Grind For Use

once the daikon is harvested, it can be stored in a cool, dry place. if you want to store it for more than a few months, you need to remove the dark green leaves. in order to use the daikon in recipes, you need to remove its skin. this is a simple process that can be done either manually or with a food processor. once the daikon is ready, you can either grind it for use or dry it for storage. daikon can be ground into a fine powder by using a grinder or a food processor. daikon can also be dried using an oven or a dehydrator. the daikon needs to be covered with a paper towel so that it doesn’t get too hot.
