The pairing of cucumber and radishes sounds like a strange one. I mean…these are two vegetables you would never want together in a salad, let alone a cooked dish.
However, in the garden, this pairing works surprisingly well and can benefit each other in both direct and indirect ways!
In this article, we’re going to discuss the upsides and a few unfortunate downsides of planting radishes with cucumbers. Let’s dive right into it!
What Makes Cucumbers & Radishes A Great Garden Pair?
While you might think I’m suggesting you pair these two great vegetables due to their contrasting colors and vibrancy, that’s actually not the case.
You see, cucumbers and radishes have slightly different growth habits.
For example, radishes grow fast and shallow, while cucumbers sprawl and are slow-starters. This allows both vegetables to grow at their own pace and in their own way without limiting each other.
Cucumbers and radishes don’t have to compete for space or nutrients. Radishes act as a “marker crop”, while cucumbers take their time to germinate and establish.
The Pest-Repelling Power Of Radishes
One of the most important qualities of radishes in this pairing is their ability to repel pests and insects thanks to their strong aroma. They can help deter cucumber beetles, aphids, and squash bugs, which are all different pests that are likely to attack cucumber plants.
Bonus point: Radishes also act as a trap crop for some pests and insects like flea beetles. This means that instead of directly repelling them, they lure these pests towards themselves, keeping them from harming other crops in the garden.
How To Plant Radishes & Cucumbers Together?
Typically, the best way to plant radishes and cucumbers together in the garden is to sow radishes around or between cucumber seedlings. It’s a good idea to space them out to avoid overcrowding (radishes won’t mind partial shade).
The deep, vibrant vegetable matures in as little as 3-4 weeks and can be pulled before cucumbers need space.
It’s not very difficult or complex to plant radishes and cucumbers together. Simply having an idea of their different requirements and catering to them is 60% of the game.
Any Downsides? What To Watch Out For…
Radishes often tend to bolt when the weather gets too hot. You want to plant them early or provide shade during the hottest part of the day.
Avoid letting old radishes rot in their beds, they can attract pests instead of repelling them. It’s better to harvest them and throw them out if they have gone bad. Whatever you do, just DO NOT let them sit in your garden for too long!
Be careful with companion plants that don’t work well with cucumbers. These may include potatoes and other brassicas. They will hurt yields and possibly cause poor fruit development due to factors like soil competition or large-scale pest infestation.

Conclusion

Now, it all comes down to personal preference. If you want to grow these separately and at different times of the year, that’s totally fine. I personally like convenience and efficiency in my garden, so for me to be able to grow cucumbers and radishes together and have them benefit from each other’s unique qualities sounds like a solid deal.
