Radishes, also known as water radishes or daikon, are a unique type of small root vegetable that’s grown around the world.

While it may look more like a teeny-tiny tree, it’s actually a standard garden variety plant – though it requires a bit more effort when compared to its garden-grown counterparts like lettuce, beets, or onions.

Traditionally, radishes are one of the lesser-grown crops, hence people know less about them than other vegetables. That’s why so many gardeners want to know how long it takes for radish plants to mature before harvesting.

This question-and-answer post provides a quick but thorough answer to the common gardening question “how long do radishes take to grow?”

Even more, we go on to explain the growth cycle of radishes and provide advice on what steps should be taken for the successful cultivation of this small root vegetable.

So, what are you waiting for? Read on and find the answer you came for!

How Long Do Radish Trees Take to Grow?

Standard garden varieties of radish take between 4 and 6 weeks to grow enough that they can be harvested – although this depends heavily upon their environment.

Note that larger species of the radish plant may require several weeks longer, to grow mature. Likewise, poorly maintained radishes may also take longer to grow.

Weather conditions such as temperature and amount of sunlight will play a large part in determining the exact length of time needed.

Furthermore, there are some varieties that take much longer than this so make sure you research these beforehand!

Pro Tips for Maximum Radish Growth

In order for your radish plants to thrive there are several steps you can take in order to ensure your radishes reach their maximum growth during the season:

1. First, choose a planting area for your radishes with plenty of direct sunlight; Radishes need 8 to 10 hours per day in order to yield good results!

2. Second, make sure that your soil has adequate drainage and nutrients; this helps prevent damping off or root rot which is common amongst many fruits and vegetables.

3. Third, regular watering throughout the season is essential; forgetting about this essential step is the quickest and easiest way to sabotage your crop.

4. Fourth, take the time to thin out extra radishes that are crowding out the others; for standard radishes, 2 inches of space is required, and 4 to 6 inches of space is necessary for larger varities.

Summary Answer

The bottom line is that when you are growing a unique root vegetable species like radishes, you must understand how long it takes for them to grow before they are healthy, ripe, and harvestable.

On average most varieties require as little as 4 to 6 weeks to grow mature. But, don’t forget that environmental factors also have an effect on things.
