During winter, reduce watering as the plant has dormant periods. It is important to water the plant at the base, keeping the foliage dry to prevent disease.
Japanese Spirea 'Candlelight' grows best in full sun to partial shade. Ideally, it should receive at least six hours of sunlight each day. The perfect spot for this plant would to be in an area that gets morning sunlight and some afternoon shade, as this helps to protect the plant from the harshest rays of the day.

- Life cycle
Japanese spirea 'Candlelight' begins its life cycle when seeds germinate in spring, after stratification which breaks dormancy. The young seedlings quickly establish a root system and grow into juvenile plants, developing stems and leaves featuring a golden-yellow color that matures to lime green in summer. This deciduous shrub reaches maturity in two to five years, during which it produces clusters of pink flowers that attract pollinators. After blooming, the flowers of Japanese spirea give way to small brown pods containing seeds, which disperse in late summer to early fall, continuing the cycle. In autumn, the foliage may turn reddish before the plant enters dormancy, shedding its leaves in response to colder temperatures. Each year in spring, the cycle is renewed as the plant breaks dormancy, sending out new shoots and leaves to start the growth process over again.
Spiraea japonica 'Candlelight', commonly known as Japanese Spirea, is most commonly propagated through softwood cuttings. The best time to propagate is in late spring or early summer when new growth is mature enough to be firm yet still flexible. Cut a 4 to 6-inch piece (10 to 15 cm) from the end of a healthy branch, making sure each cutting has at least two sets of leaves. Remove the leaves from the lower half of the cutting, dip the cut end in rooting hormone, and insert it into a pot filled with well-draining potting mix. Ensure the pot stays moist and is placed in indirect sunlight. Rooting can be expected in a few weeks, after which new growth will indicate the cutting has successfully taken root and can eventually be transplanted outdoors.
