Neither diseases nor pests are common with Dipladenia, because the plant is quite resistant in this respect. However, this only applies if it is in a suitable location with lots of light and warmth.
What diseases can occur with Dipladenia and how can I prevent them?
Diseases in Dipladenia can be caused by fungal infection, shoot death or sunburn. To prevent this, you should place the plant in a bright, warm location, water moderately and avoid waterlogging.
What diseases does Dipladenia suffer from?
If you notice a fungal infection on your Mandevilla, as Dipladenia is also called, then it is probably because the plant has received too much moisture. Either it is in a moist and perhaps shady location or it has been watered too much. If you spot leaf spots, cut off affected leaves and shoots. If the infestation is severe, also use a fungicide.
Shoot death, on the other hand, is more likely due to waterlogging. Unfortunately, the affected plant usually cannot be saved. If the leaves turn brown, then the Dipladenia may have been sunburned or overwintered in too dark a place. However, a few yellow leaves in summer are nothing to worry about; they are completely normal, especially on older shoots.
How can I prevent illness in my Dipladenia?
The best way to prevent disease in your Dipladenia is with good care and the perfect location. The plant does not tolerate darkness or waterlogging. It can also be kept as a houseplant. However, there should be no drafts there. Keep your Dipladenia bright and warm, as it only blooms at temperatures around 20 °C.
How to properly care for your Dipladenia
Water your Dipladenia moderately about once or twice a week. In a hot summer, check the soil more often for dryness and water more frequently if necessary. As a rule, the Dipladenia tolerates a few days without water better than watering it too frequently. Don't forget to fertilize during the flowering period, the Mandevilla has a high need for nutrients.
The best prevention against disease:
- the right location: warm and bright
- Watering properly: only moderately
- Avoid waterlogging
