In my experience as a gardening and landscaping expert, I have found that aralia, also known as Japanese spikenard, can be grown successfully in a range of light conditions. While it is generally recommended to plant aralia in part to light shade, there are instances where it can tolerate full sun if certain conditions are met.
Aralia is native to forests and woodlands, where it naturally grows in dappled shade. Therefore, providing it with some shade or filtered sunlight tends to be the ideal situation for this perennial. It helps to mimic its natural habitat and promotes healthy growth. However, I have seen aralia thrive in full sun as well, as long as certain considerations are taken into account.
Firstly, it is important to note that aralia in full sun requires consistent moisture. The increased exposure to sunlight can lead to quicker evaporation of moisture from the soil, potentially causing the plant to dry out. Therefore, regular watering is crucial to maintain the plant’s health in these conditions. I recommend checking the soil moisture regularly and adjusting the watering schedule accordingly.
In addition to adequate moisture, providing some form of protection from intense afternoon sun can also help aralia in full sun. This can be achieved by planting it in a location where it receives morning sunlight or by using shade cloth or other forms of temporary shading during the hottest parts of the day. This will prevent the plant from getting sunburned or stressed by excessive heat.
Another important aspect to consider when growing aralia in full sun is the soil quality. Ensuring that the soil is well-draining and rich in organic matter is vital for the plant’s overall health and ability to tolerate sun exposure. Amending the soil with compost or well-rotted manure before planting can help improve its structure and nutrient content. Additionally, mulching around the base of the plant can help retain moisture and regulate soil temperature, further benefiting aralia in full sun.
It is worth mentioning that aralia may exhibit some signs of stress or leaf scorch when exposed to prolonged periods of intense sunlight, even with the aforementioned precautions. This can manifest as browning or yellowing of the leaves. However, with proper care and attention, the plant can often recover and continue to thrive.
While aralia generally prefers part to light shade, it can tolerate full sun if certain conditions are met. Adequate moisture, protection from intense afternoon sun, and well-draining soil with organic matter are key factors in successfully growing aralia in full sun. However, it is important to monitor the plant closely and provide extra care if signs of stress or leaf scorch appear.
