Sowing radishes: 3 alternatives to garden beds

Radishes, the crunchy tubers, are almost always sown and harvested directly in the garden. The vegetables can even be grown on the windowsill.

They are crisp, red, hot and also healthy. Radishes are one of the most popular vegetables in home gardens. The useful plant belongs to the cruciferous family, as does the radish, each individual bulb can be up to 4 cm thick.

Whether just nibbled away with a little salt, on a sandwich or as a salad ingredient, radishes are always refreshing in taste. The small balls get the healthy factor mainly from the high mustard oil content, which is also responsible for the sharpness. The highly effective plant substance is particularly good for our digestive tract, since mustard oil kills bacteria and fungi. Those interested can find out more about natural antibiotics on

Anyone who has sown radishes in a normal garden bed should take a closer look at this post. You have the opportunity to plant radishes in different ways. This means that lovers who do not have a large garden can also enjoy themselves.

Alternative 1: prefer radishes on the windowsill

Even if most hobby gardeners prefer to sow their radishes directly in the garden, it is possible to prefer them on the windowsill. The best time is February. In order for it to work, there are a few points to consider.

Which vessel is suitable?

The key to success is where you sow the seeds. So-called jiffies are best suited. These are small peat swell pots that accelerate the root and germ formation of the plants. At Amazon, the source pots are available in different packages. If you want to try it out first, the 36-piece version is sufficient. The jiffies are placed in lukewarm water and then swell in them. When they have reached their correct volume, the excess water is squeezed out. Now pierce small holes with a stick and sow the radish seeds. Place all Jiffys in a plastic bowl and place in a bright, warm place. A window sill, possibly with a radiator underneath, is perfect. It is important that the radish sowing is now always kept moist. However, waterlogging should be avoided, otherwise there is a risk of mold.

If you don't want to use Jiffys, you can also use commercially available growing trays to advance the radishes. When buying, make sure that the floor is not smooth. The more grooves there are, the better the water can be distributed. The lid should be transparent, because sufficient brightness is a basic criterion for good growth. In addition, a warm, humid climate forms under the "roof", giving the plants strength. Otherwise it can happen that the radishes just shoot up.

Alternative 2: sow radishes in the raised bed

The classic raised bed is not only gentle on the back but also practical, because it can be placed in the garden, on the terrace or on the balcony. Which plants and vegetables grow best in the raised bed depends on the location. The guide on describes exactly what advantages the different orientations (north, south, etc.) have. When buying, be sure to pay attention to the wood quality and that the raised bed can be expanded. So you have the opportunity to plant more vegetables or herbs at any time. My recommendation is clearly a raised bed made of larch wood. It is simply the most weather-resistant wood, robust and, above all, it can stay outside even in winter. From an ecological point of view, the wood should be untreated, otherwise pollutants can be released into the potting soil and "attack" your radishes.

In order to avoid one-sided nutrient absorption, you should always create a mixed culture. That means the radishes get company. As a rule of thumb: larger plants inside, the small ones on the edge. For example, if you wanted to plant cabbage with the radishes, the large leaves would quickly take the light away from the little red ones.

These varieties go well with radishes

  • onions
  • carrots
  • salad
  • spinach
  • tomatoes
  • zucchini

Radishes are sown in the raised bed from mid-February. However, you should rather depend on the weather. If the earth is still very wet and cold, it is better to wait a few more weeks.

Alternative 3: sow radishes in the greenhouse

If you own a greenhouse, you can sow your radishes in March. Choose a bright to partially shaded place. It is important that the floor is well prepared. This video shows what needs to be considered:

When the earth is loosened up, sowing begins. For this, several rows with a depth of about 1 cm are drawn. Under no circumstances should the radish seed be brought in deeper, otherwise the tubers will grow in length and lose their typical round shape. The distance between the grooves is a good 10 cm. A seed is now "laid" every 4 cm. If the bag is empty, loosely pour some soil over it with your hand and close all rows. Please do not press firmly, otherwise the radishes have no place to sprout.

From now on it is up to the care of the sowing, that is, the radishes must be kept evenly moist, even if no stem can be seen. The first harvest can then take place after about 4 weeks, depending on the variety it may take a little longer. The advantage of sowing in the greenhouse is that you can sow again at any time and thus have crispy radishes throughout the season.
