Once I was first launched to daikon radishes, I used to be so amazed by their dimension that I needed to attempt rising them myself. However a lot to my disappointment, my daikons didn’t get anyplace as giant as I used to be anticipating them to get. Seems, there have been a few errors I used to be making.
Daikon radishes might develop small in the event that they’re planted too shut collectively, aren’t getting sufficient daylight, or the temperature is simply too sizzling. In the event you’re rising in raised beds, your beds will not be deep sufficient for these lengthy radishes to achieve their full size.
This information will enable you to to not make the identical errors I did as I’ll share the information and tips that I’ve now realized for rising massive, stunning daikon radishes.
Why your daikon radishes aren’t getting massive
These are the widespread errors that almost all gardeners make when rising daikon radishes that may considerably stunt the plant’s progress. Fortunately, there’s an answer to all of them.
Daikons planted too shut collectively
Like most vegetation, daikon radishes don’t prefer to compete with different vegetation for area. These radishes can develop to be about 2 ft lengthy and their inexperienced leaves can unfold out so far as 3 ft in any path.
Plant your radishes about an inch aside after which skinny them out as they develop. By the point they attain full maturity, they need to be about 4 to five inches aside.
Daikons not getting sufficient daylight
Radishes are typically a low-maintenance crop and might typically really feel like a kind of issues which you could simply plant and neglect about till it’s time to reap. That’s what I assumed anyway.
In case your daikon radishes aren’t getting sufficient solar, then their roots won’t get that massive they usually’ll focus their power on producing larger leaves. Make it possible for the world the place you plant your daikons will get at the least 6 hours of daylight per day.
The skin temperature is simply too heat
Radishes are within the brassica household with different widespread veggies like broccoli, cauliflower, kale, and cabbage. These are also called cool-season crops. As you’ll be able to in all probability guess by the identify, cool-season crops don’t do effectively in hotter temperatures.
When radishes are uncovered to a number of days of sizzling climate (temperatures constantly over 85 levels) they may begin to bolt earlier than reaching their full dimension. As soon as a radish bolts, its taste high quality is severely diminished and might grow to be fairly bitter.
For these in temperate local weather zones, the most effective time to develop daikons is within the spring or fall season. This fashion you’re avoiding the summer season warmth.
Raised beds aren’t deep sufficient
In the event you’re rising daikons in any form of raised mattress, it’s essential to guarantee that the mattress is deep sufficient.
As I discussed earlier than, daikons might be as much as 2 ft in size. In the event you’re having a tough time picturing that, think about a radish that’s the size of your forearm from fingertip to elbow. Typically they are often even longer!
In case your raised mattress is simply too brief vertically, the radish has nowhere to go. Typically they will proceed to develop into the bottom beneath your raised beds however provided that the soil shouldn’t be too compacted.
Equally, for those who positioned a chunk of material within the backside of your raised mattress earlier than filling it with soil, the daikons can have a troublesome time rising by means of this cloth.
How you can develop massive daikon radishes
Planting your daikon radishes far sufficient aside, in well-lit areas, and in raised beds which are deep sufficient for the roots to develop will definitely set your daikon radishes up for fulfillment. However listed below are another good issues you are able to do to maximise daikon radish progress.
Soil and water preferences
Daikon radishes choose unfastened loamy soil with a barely acidic pH between 6 and 6.5. In case your soil is barely compacted, haven’t any worry. Daikon radishes are literally incredible at rising by means of fairly tough soil.
Except your soil is nearly impenetrable with a dibbler, your daikons should not have any downside breaking by means of the soil. Don’t have a dibbler? Take a look at this text that can assist you work out the most effective dibbler to your backyard.

Direct seed daikon radishes
The easiest way to get good germination in your daikon radishes is to plant the seeds straight into the bottom as a substitute of beginning them indoors and transplanting them later.
Radish seedlings are very tender and might be very troublesome to transplant leaving you with broken roots and poor plant progress.
However with direct seeding, thinning your radish seedlings turns into crucial as I discussed earlier. It’s a bit tedious to try to get good spacing with such small seeds so it’s okay in case your seeds are planted shut collectively and also you skinny them out as they develop.

If in case you have the area in your backyard for it, I’d extremely advocate succession planting. Daikon radishes are these “one-and-done” kinds of vegetation that means that after they’re harvested, they received’t produce anymore until you plant extra seeds.
That is the place succession planting turns out to be useful. In the event you plant new daikon seeds each two weeks then you should have new radishes to reap each two weeks as soon as they attain full maturity.
That is useful since you received’t be bombarded with a ton of big daikons unexpectedly since their harvesting can be staggered. It could actually additionally prolong your season so that you’ve got a steady radish harvest for a number of weeks.
When are daikon radishes prepared for harvest?
You may anticipate your daikon radishes to achieve full maturity in about 40 to 70 days from when the seeds have been planted.
Much like carrots, the highest of daikons will begin to stick out of the bottom as they get nearer to their harvest date. They need to have good full leaves on the highest which are between 7-12 inches in size. The leaves are additionally edible by the best way!
It may be arduous to inform when root crops are prepared for harvest as a result of we are able to’t see what they appear to be underground. At any time when I’m not sure, I pull a check one simply to test on its progress.
Daikon radishes must be at the least 8 inches in size after they’re prepared however oftentimes they’re a lot larger than that.
Hopefully, you’ve discovered this data useful and are wanting ahead to rising tons of big daikons this yr. So long as you area them far sufficient aside, give them loads of daylight, and ensure your beds are deep sufficient for them to unfold their roots, you’ll have the most important and most stunning daikon radishes you’ve ever seen.
