Light Requirements
Solidago arguta Ait. var. arguta grows best in full sun but can tolerate partial shade. It requires a minimum of 6 hours of direct sunlight per day for healthy growth and blooming.
Temperature Requirements
This plant variety prefers moderate temperatures ranging from 18 to 25°C during the day and 10 to 15°C at night. It can tolerate colder temperatures but not frost.
Soil Requirements
Solidago arguta Ait. var. arguta can grow in various soil types, including loam, sand, or clay, but thrives best in well-draining soil. The ideal soil pH level for this plant is between 5.5 and 6.5. It can tolerate acidic soils but not extremely alkaline ones.
Organic matter content in the soil enhances the plant's growth and health. Adding compost to the soil before planting helps to improve soil fertility and drainage. Sufficient moisture is essential for successful growth, but the soil shouldn't remain saturated as it can lead to root rot.
Cultivation methods
Solidago arguta Ait. var. arguta is a perennial plant that grows well in USDA zones 3-9. It prefers full sun exposure but can also tolerate partial shade. The plant's soil should be well-draining and rich in organic matter, with a pH range of 6.0-7.5. The ideal time for planting is in early spring, although it can also be planted in the fall.
Watering needs
The plant needs regular watering during its growing season. The soil should be kept moist but not waterlogged, as excess moisture can cause root rot. In hot and dry weather, the plant may require more frequent watering. It is advisable to water the plant in the early morning or late afternoon to avoid evaporation in the mid-day sun.
Fertilization
It is necessary to fertilize Solidago arguta Ait. var. arguta for optimal growth and flowering. Fertilize the plant once a month during the growing season using a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Avoid over-fertilization, as it can lead to excessive leafy growth at the expense of flowering.
Pruning
Pruning helps to keep the plant compact and encourage new growth. After flowering, cut the faded blooms to encourage secondary blooms. In late winter or early spring, prune away any dead or damaged stems and remove one-third of the plant's overall growth to promote bushier growth. Avoid pruning after mid-summer, as this can remove the new growth that will produce flowers the following year.
Propagation of Solidago arguta Ait. var. arguta
Solidago arguta Ait. var. arguta can be propagated by either seeds or division. Both methods are easy and can be done in spring or fall.
Propagation by seeds
The seeds of Solidago arguta Ait. var. arguta can be collected from the plant when they are fully mature in autumn. The seeds should be sown in a well-draining soil mix in a container, under bright light. The soil should be kept evenly moist until the seeds germinate, which usually takes about one to two weeks.
Propagation by division
Propagation by division is best done in spring or fall when the plant is not in active growth. Using a sharp garden knife or shovel, the plant can be carefully dug up and divided into sections. Each section should have several healthy roots and stems. The divided sections can be planted in a prepared bed or in containers, using a well-draining soil mix.
