Spiraea japonica aka Japanese Spiraea

Japanese Spiraea requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

Japanese Spiraea should be watered regularly, allowing the soil to dry out between waterings.

When growing Japanese Spiraea, it is important to pay attention to the soil type you are using. This plant is very sensitive to dry soil and needs a potting soil that retains moisture. A good soil should still be well-draining and contain lots of organic matter. Coco coir or sphagnum moss are great options to provide the Japanese Spiraea with the nutrients and moisture it needs. The added organic matter will also help the soil retain water and prevent the Japanese Spiraea from drying out too quickly. Before planting, make sure to mix compost or manure into the soil for extra nutrients. Also, make sure to water the Japanese Spiraea regularly, making sure to keep the soil evenly moist but never soggy. With the correct soil and watering regimen, the Japanese Spiraea will thrive and bring lots of beauty to your home.

To ensure optimal growth, the Japanese Spiraea prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

During the cold period, it is common for Japanese Spiraea to go dormant and their growth may slow down, so waterings should be spaced out more during this period.

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

The Japanese Spiraea should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Japanese Spiraea’s native range is E. Asia - Japan.
