The oleander, which grows up to five meters high, can often be found in German gardens during the summer months. Since the oleander, with its long, shiny leaves and delicate flowers, is not hardy, it should, if possible, overwinter in a cool, but frost-free and bright room. The plant can tolerate a maximum of minus five degrees Celsius, but only for a very short period of time.
How often should you water oleander in winter?
During the winter break, you should water the oleander at least once a week with stale, warmed tap water. Make sure that the amount of water is less than in summer and check the moisture requirement with your fingers.
Water oleander once a week
During the growing season, the oleander is always “hungry” and “thirsty”, i.e. H. The heavy feeder needs to be fertilized and watered regularly and frequently. You can stop fertilizing during the winter break - after all, the oleander takes a break from growth in the cold season. While you are overwintering your oleander, you should definitely not stop watering! Water your oleander at least once a week, but not as lavishly as in summer. Use your fingers to check whether watering is even necessary before giving water.
Tip
Oleander should never be watered with rainwater, but always with stale and warmed tap water.
