When it is in bloom, it looks attractive with its umbellate flowers, which are up to 30 cm large, and the Japanese Aralia also looks attractive as a large shrub. But when their leaves turn yellow and fall off, something is wrong, right?
Why is my Aralia losing leaves?
A Japanese Aralia loses leaves due to natural fall foliage infestation, root rot caused by too moist soil, nutrient deficiency, disease or pest infestation, sudden temperature changes, too much direct sunlight or a damaged root system. Avoid these factors through suitable location selection, care and regular inspection.
Reasons that may lie behind it
Several aspects can underlie leaf shedding. Here are the most common reasons:
- Autumn: Falling leaves is natural
- Root rot – soil that is too moist
- extreme nutrient deficiency
- Disease infestation
- Pest Infestation
- sudden temperature change
- too much direct sunlight
- damaged roots
Countermeasures – Prevention is better than aftercare
First of all, the location for this Aralia is crucial to ensuring that it does not drop leaves. It should be planted in a semi-shady place. She doesn't feel comfortable in the blazing sun. It is not uncommon for heat to build up there in summer. This plant doesn't benefit from this at all.
The next point is care. This plant places value on a moist subsoil. It has shallow roots and should therefore be watered in dry conditions. But there should not be any accumulation of moisture. Therefore, make sure to create good drainage in the soil (€155.00 on Amazon) when planting the aralia.
It is also important that the Japanese Aralia is fertilized once a month. If necessary, it will be cut. You should thin out the bush regularly to avoid baldness. Branches that are too old lose their leaves and become increasingly bare.
What he althy leaves look like
A he althy Japanese aralia sprouts new plants every spring and sheds its leaves in autumn. During the spring and summer period, it displays leaves in a dark green color. The color is lighter on the underside of the leaf.
The leaves grow up to 100 cm long. They are bipinnate and arrange themselves in an alternating sequence around the branches. Their texture is thin and smooth. The individual leaflets taper to a point at the end and are wedge-shaped at the base.
Tip
When inspecting the shed leaves, be sure to dispose of them afterwards. Otherwise, pets or small children could eat them and become poisoned.
