Wintering azaleas - This is how it's done


Indoor azaleas are considered annual plants that are disposed of immediately after flowering. Garden azaleas, however, are preserved. But why is it like that? Can't you overwinter the azalea from the house? We tell you.

Basically, you need to know that the azalea's heyday falls in autumn and winter. The term wintering is therefore rather inappropriate.

Rather ask yourself the question of whether the houseplants can bloom several times in a row and how you can do this.

Wintering begins with extending the flowering time of the plant.

There are three tricks here:

  • Cool location
  • No drafts
  • No direct sun

➩ Demands on the Zimmerazalee

The ideal temperature for a long flowering period is between 8 and 16 degrees. The bedroom is often the perfect place for an azalea, but the hallway or kitchen can also be suitable. Drafts must always be avoided as the carpenter azalea quickly draws back the strength from the flowers, which promotes fading. The flowers don't like direct sun at all, which means they quickly wither. For the longest possible flowering time, the plant should experience at most some morning or evening sun.

When the flowering period is over, the Zimmerazalee looks bare and unattractive. You do not need to dispose of them, however, because with the right tricks, the plant will bloom again next year.

➩ Enjoy indoor azaleas for several years

When the flowers have withered, the time has come for the right care that will allow you to overwinter.

1 In the first step, the remaining seed heads must be carefully removed and cut out. This is important because the seeds will continue to be nourished by the plant and it will lack the strength to develop flowers. Therefore, remove the seed heads and repot the azalea. The plant should now be stored in a bright but cool place by May.

2 In May, place the Zimmerazalee outdoors. Choose a shady and sheltered place where there is no drafts. If you have the opportunity, plant the azalea in a shady flower bed. Make sure that the root ball is always moist, but does not form waterlogging. As soon as night temperatures drop in the first days of September, the azalea will form new buds.

3 Before the first night frost, bring the plant back into the apartment and put it in a cool place.

In summary, you can enjoy your azalea for several years if you:

  • Remove seed heads after the last flowering
  • store the plant in a cool, cool place until May
  • Bring the azalea outdoors from May to September
  • choose a shady summer spot
  • Bring the azalea into the house before the first night frost

➩ Overwinter garden azaleas

Mid-high or high azaleas, which may decorate the flower beds in the garden or form hedges, can of course remain in the garden over the winter even when there is frost. These are usually the rhododendrons, whose leaves fall off in winter, so that the plant can provide excellent protection against the cold.

Azaleas in tubs
If you keep half-high azaleas in tubs on the terrace or balcony, you must protect the plant in winter. Night frost damages tub plants because the roots do not protrude deep enough to absorb water. So bring your azalea in the planter into the apartment before the first night frost and place it in a shady and cool place. The location selection should not be close to the heating system and should not offer any drafts. If you cut back the seed heads of the container plants after the flowering period, the azalea will form new buds the following autumn.

With these tricks, you will be able to enjoy wonderful flowers in late autumn and early winter and ensure that you will enjoy the flowers for several years.

If you don't want to see the bare green in summer, you can easily put the azalea in a flower bed and plant tall shrubs around it. The perennials give important shade to the azalea and prevent you from having to look at the bare green throughout the summer.
