Many flowers have to be brought indoors in winter. But not hardy geraniums. Read here how to plant them properly and bring them well over the winter.

There are many different types of geraniums

Geraniums are among the most popular balcony plants or terrace plants in our latitudes. Which is why they are now available in a variety of flower colors and even with different flower shapes. In the meantime, the gardening trade now also has hardy geranium varieties ready for outdoor planting, which means that the often laborious storage of the plants in the winter months is no longer necessary.

Well suited for outdoors: the Geranium varieties

For the field, the varieties Geranium (cultivated form of the cranesbill) are usually offered, which have nothing in common with the genus Pelargonium (the so-called balcony geraniums). Balcony geraniums (pelargonium) must continue to be stored in winter because they can no longer withstand the lowest freezing temperatures.

We would now like to explain to you how to plant hardy geraniums and how to protect them from frost temperatures in winter. Because although the geraniums are hardy, they still have to be protected a little in winter.

Plant geraniums outdoors

Geranium field planting has the clear advantage that the hardy plants can remain in the soil for several years. When planting outdoors, you should always choose a sunny, moderately shaded location. And a nutrient-rich soil would also be very good for the geraniums.

Alternatively, you can also plant the hardy geraniums in flower pots and e.g. as a container plant on the terrace or balcony.

Hardy geraniums can also be planted in tubs or the like

The outdoor geraniums (usually with double flower shape) are currently available in the flower colors red, pink, white and violet (also two-tone). Further breeding will surely follow in the coming years.

Make winter arrangements

Even if the geraniums are winter hardy, you still have to take some precautions in the field to protect the geraniums, which are actually sensitive, but still very easy to care for, from frost temperatures. You have to differentiate between geraniums in the bed and geraniums in the flower pot.

»Winter protection for geraniums in the bed:

  • Always cut back geraniums generously in autumn.
  • Cover geraniums with brushwood, straw, jute or garden fleece in the winter months.
  • Reveal in spring (around March) and maintain the geraniums evenly as required (e.g. watering).
  • Provide sufficient full fertilizer or special geranium fertilizer (from around the end of May) 2 to 4 times a month.
  • Important: check geraniums for pests!
Cover geraniums in winter e.g. with straw and brushwood

»Winter protection for geraniums in a bucket:

If you don't want to plant the hardy geraniums directly outdoors, but in garden pots, then of course you have to protect them in the winter months with special insulation so that the plants do not freeze in the pots. The best way to protect the tub plants is to:

  1. wrap the crown of the plant with fleece
  2. Place pine twigs or garden fleece around the trunk
  3. Wrap bubble wrap around the pot
  4. cover the bubble wrap with a burlap sack
  5. Place the container plant on a styrofoam plate (so you don't have to buy special pot insulation)
It is best to cover potted plants with bubble wrap and burlap sack

Propagation and promotion of the after-bloom

»Propagate geraniums:

Would you like to propagate your geraniums? No problem! You can propagate the approximately 30 to 40 centimeters tall free-range geraniums simply by dividing the planting sticks.

»Promote post flowering:

Cut back the first full bloom of the geraniums including style in the summer months (around June to July), then usually there is even a subsequent bloom (until September). Only then should you completely cut back the plant in autumn.
