Is the Madagascar jasmine (Dipladenia) toxic? There are things to know about keeping it at home and smelling its fragrance

Have you ever thought about creating an eye-catching flower wall in your own garden? Then this "Madagascar jasmine," available in red, peach, and pink, and also fragrant, is perfect for you! Not only does it bloom continuously through all four seasons, but it also pairs well with other climbing plants.

Madagascar jasmine belongs to the Apocynaceae family. Many people mistakenly believe it contains toxins, but the truth is that it is not toxic, and as long as you are not allergic, you can safely keep it in your garden. In terms of care, if you want to ensure the flowers keep opening and are of top quality, you must place it in a well-ventilated environment, because after blooming its fragrance is quite strong, and at certain times smelling it can easily cause nasal discomfort.

In daily care, Madagascar jasmine likes heat and light, can tolerate ambient temperatures of around 20-30°C, and can be given partial sun or full sun. If light is insufficient or the environment is too shaded, the plant will produce fewer flowers later on. Its cold tolerance is relatively poor: as soon as the overall temperature drops below 10°C, cold damage occurs.

In other respects, Madagascar jasmine is fairly adaptable. Its only soil requirement is fertility; when choosing, just pick a sandy loam rich in humus and with good drainage. If you want to be extra careful with it, you can also add a nutrient solution to the soil before the growing season. Doing so can supplement the soil's nutrient content and enhance the adaptability of the root system.

As for watering and fertilising, Madagascar jasmine only needs the soil kept moist; do not overwater, because its roots are relatively fine and sensitive. A watering frequency of 1-2 times per week is usually recommended, and in summer, when moisture evaporates quickly, the number of waterings can be appropriately increased. As for fertilising, the flowering period is mainly concentrated in summer and autumn, and at this time fertilising once a month is enough. Do not use too much fertiliser; it is recommended to use a fertiliser rich in potassium, phosphorus, and nitrogen.

Regarding pruning, pests, and diseases: when pruning Madagascar jasmine, it is recommended to wear gloves. Although the sap has no obvious toxicity, you should still be careful in case of skin sensitivity. Common pests and diseases include powdery mildew and aphids. For early prevention, you can disinfect the soil before planting, and later, during care, pay attention to regular weeding and clearing away fallen leaves, which can prevent pests and diseases from breeding.
