  • water dropWater

    Russian olive 'Quicksilver' prefers dry conditions and established plants are quite drought-tolerant, requiring minimal watering. Young plants should be watered deeply once a week to help them establish a strong root system. After the first growing season, it's best to water only when there is a pronounced period of drought. Typically, this may mean watering with about 1 to 2 gallons every two to four weeks during prolonged dry spells. Always allow the soil to dry out between waterings to prevent overwatering and potential root rot.

  • sunLight

    Russian olive 'Quicksilver' performs best in full sun, which means it should receive at least six hours of direct sunlight daily. However, it can tolerate partial shade, though its growth might not be as robust. The ideal spot for this plant is an area with unobstructed access to sunlight for the majority of the day, ensuring healthy growth and development.

  • thermometerTemperature

    Russian olive 'Quicksilver' is hardy and can survive in a range of temperatures, comfortably withstanding winter lows down to about -20°F and summer highs well into the 90s°F. While the plant can tolerate quite a bit of temperature fluctuation, the ideal temperature range for optimal growth is between 60°F and 80°F. Extreme and prolonged temperatures outside of this range may hinder growth or cause stress to the plant.

  • scissorsPruning

    Prune Russian olive 'Quicksilver' to shape the plant, control its size, or remove any damaged or diseased branches. Pruning should be done in late winter or early spring before new growth begins. It's generally recommended to prune no more than one-third of the plant at a time to avoid stressing it. Prune as needed, typically every couple of years, to maintain the desired form and promote healthy growth.

  • circleLife cycle

    Elaeagnus 'Quicksilver', also known as Quicksilver Oleaster, begins its life as a seed, typically requiring well-drained soil and full sun to germinate. Once sprouted, the seedling quickly establishes a root system and starts to develop silver-gray leaves on long, arching branches, entering a vigorous juvenile growth phase. Throughout its maturation, Quicksilver Oleaster reaches flowering maturity in a few years, producing small, inconspicuous but fragrant flowers that attract pollinators. Following flowering, the plant may produce small fruit, albeit infrequently, completing its reproductive cycle. This deciduous shrub continues to grow, eventually reaching up to 12 feet or more in height and width, and may require pruning to maintain shape and health. The life span of Quicksilver Oleaster can extend several decades, with the plant enduring through seasonal cycles of growth, flowering, and dormancy annually.

      Spring-Early Summer

    • Elaeagnus 'Quicksilver', commonly known as Silverberry or Wolf Willow, can be propagated most effectively through semi-hardwood cuttings. This method typically takes place in late summer. Cut a length of stem that includes several leaves and is about 4-6 inches (10-15 cm) long. The cutting should be taken from new growth that is beginning to harden but is not yet fully mature. Remove the leaves from the lower half of the cutting, dip the cut end into rooting hormone, and then insert it into a well-draining soil mix. The cutting should be kept moist and in a warm, shaded spot until roots have developed, which can take several weeks. Once the cutting has rooted, it can be transplanted into a larger pot or directly into the ground.
