Angel trumpets are not winter hardy, they must be put in a place to overwinter at the end of the gardening season. Here they lose all their leaves and, if the conditions are right, they will sprout again the next spring. Because of their height, they can be cut back, but they cause space problems for many plant lovers. In regions where there are no long night frosts, angel trumpets can also grow in the open garden.
Due to the toxicity of the angel's trumpet and the appearance of the fruit capsule, which is particularly tempting for children, there should be no angel's trumpet in a household with children. But other plants from the nightshade family are also poisonous and contain the same substances.
Causes of yellow leaves
There are various causes for yellow leaves on the angel trumpet. We show what they are and how you can prevent yellow leaves on the angel trumpet with the right knowledge and action.

Nutrient Deficiency
If the leaves of the angel's trumpet turn yellow, there is usually a nutrient deficiency. You also have to always remember that plants need a lot of water. On hot days it is better to water in the morning and evening. Lack of water is shown by drooping leaves. If watered quickly, they will recover.

Angel trumpets do not require any special soil. However, they must be sufficiently fertilized to meet their high nutrient requirements. Angel trumpets are heavy feeders. You can hardly over-fertilize them. The plants need enormous amounts of fertilizer, especially to form flowers. It is best to fertilize once a week. It is also a good idea to incorporate slow-release fertilizer at the beginning of the year. A combination of both ensures the right supply of nutrients. Fertilizer applications will be stopped from mid-August.
Iron deficiency
If you have an iron deficiency, water it daily with a special recipe. Take a heaped tablespoon of lime and a tablespoon of iron powder per 10 liters of irrigation water. The ingredients must be well dissolved. You should see improvement quickly. Once the leaves are green again, use this special mixture only every 14 days.
Spider mites
Spider mites can also cause yellow leaves. You should regularly examine angel trumpets for these pests and, if necessary, take countermeasures.

- A lot of fertilizer helps in most cases to eliminate yellow leaves.to prevent their occurrence. It may be necessary to try something out. Some angel trumpets like blue seed dissolved in water, others prefer flowering plant fertilizer. The intervals can also be tried out.
