Japanese spurge

Japanese Spurge does not require a huge amount of water. When established, water only when the soil appears dry. Once weekly watering is usually enough during dry times. During drought conditions, withhold water for several months.

Japanese Spurge prefers a shade to dappled sun setting. When located in areas with full sun, it can become weedy and leggy. Full shade is also acceptable, as long as the soil drains well.

Japanese Spurge will tolerate both very warm (up to 95°F) and slightly cool temperatures (down to 70°F). In cold climates, the plant will survive winter temperatures of down to -40°F (C -40°C).

Japanese Spurge prefers some humidity but does not require it. It will grow well in both high humidity and low humidity conditions.

Japanese Spurge prefers a rich but well-draining soil with a slightly acidic to neutral pH. The soil should be kept moist but not soggy, and the plant should never be allowed to sit in water. If the soil becomes overly wet, it can cause root rot.

Japanese Spurge should be fertilized during the growing season, from late spring until late summer. Use a balanced fertilizer low in nitrogen and apply it every two to three weeks. Be sure not to over-fertilize; too much fertilizer can cause the plant to become leggy and weak.

Common pests that may infest Japanese Spurge include aphids, spider mites, leaf miners, and mealybugs. These pests can be controlled with an insecticidal soap or horticultural oil. Consult with your local nursery professional to ensure that the product is safe for Japanese Spurge. If you don’t want to use a chemical, you can also try a garlic spray or a homemade soap solution.

Japanese Spurge typically does not need to be repotted. It is best to leave the plant alone so it can spread and fill in a given area. If the plant outgrows its space, it's best to divide or transplant the clumps to a larger space.

Although Japanese Spurge naturally forms attractive mounds that can reach up to a foot in height, it can be also be pruned for a more manicured look. Pruning should be done in the early spring, just as new growth begins. Cut back any stem that looks leggy or weak, or prune back the entire plant if it becomes too tall or wide.

Japanese Spurge benefits from a layer of organic mulch such as straw or shredded bark. Mulching helps keep the soil moist and reduces weeds.

Japanese Spurge can be propagated either by seed or by division of the clumps. To propagate from seed, sow the seeds in the spring or fall in a light, well-draining soil. To propagate by division, dig up the clumps and divide them into smaller clumps. Then replant those clumps in the desired location.

Japanese Spurge rarely needs support, but may benefit from a stake or trellis if it's planted in an area with strong winds or heavy rains.

Japanese Spurge does not require a winter rest period but it may benefit from one. At the end of spring, stop watering the plant and allow it to go dormant. Water sparingly in the winter and begin regular watering again in early spring.

Japanese Spurge is not toxic to animals, making it a safe choice for households with pets.
