White Fir Abies concolor 'Compacta'
ABOUT
The plant known as 'Compacta' is a variety of White Fir that exhibits a dense, conical shape with compact growth habit, giving it a full and lush appearance. The needles of this plant are long and soft, typically showing a blue-green or silvery color that adds a distinctly cool and calm aesthetic to its overall look. The branches are well-covered in these attractive needles, which can give the plant a somewhat fluffy texture. This cultivar maintains its color throughout the seasons, providing year-round interest in the garden or landscape where it is planted. The needles are arranged in a spiral pattern on the branches, but because they twist at the base, they appear to be arranged more in two ranks, creating a somewhat flattened appearance. Additionally, the 'Compacta' produces cones, but they may not be readily visible among the dense foliage. These cones are smaller than those of the typical species and add an ornamental value to the plant when they are present. Overall, the White Fir 'Compacta' is known for its neat and orderly appearance, requiring minimal maintenance to keep its shape. It is often chosen by gardeners and landscapers for its reliable form and striking needle coloration.

WaterWhite fir 'Compacta' needs regular watering, particularly during dry spells. Young trees should be watered once a week with about 1 to 2 gallons of water, ensuring moisture reaches deep into the soil. As the tree matures, it becomes more drought-tolerant, requiring less frequent watering. However, during prolonged dry periods, it is important to water the tree every two to three weeks. It's essential to avoid waterlogging, as this can lead to root rot.
LightWhite fir 'Compacta' prefers full sun to partial shade. The ideal spot for this plant would receive sunlight for at least six hours a day. Avoiding deep shade is crucial, as too little light will hamper the growth and density of the foliage.
TemperatureWhite fir 'Compacta' is hardy and can endure temperatures as low as -40 degrees Fahrenheit, making it suitable for colder climates. Its ideal temperature range is between 40 to 70 degrees Fahrenheit, though it can survive in warmer temperatures as long as it is not prolonged or accompanied by high humidity levels.
PruningPruning of White fir 'Compacta' should be minimal, focusing on removing dead or damaged branches as needed. The best time for pruning is in late winter or early spring before the tree's new growth starts. Over-pruning should be avoided to maintain the plant's natural compact shape.
CleaningAs needed
SoilWhite Fir 'Compacta' thrives best in well-draining, moist soil with a pH of slightly acidic to neutral, around 6.0 to 7.0. Create a soil mix by combining equal parts loamy soil, peat, and coarse sand or perlite to ensure proper aeration and water retention.
RepottingWhite Fir 'Compacta' is a slow-growing conifer and thus does not require frequent repotting. Repot once every 3 to 5 years, in the spring, to freshen the soil and address any potential root binding.
Humidity & MistingWhite Fir 'Compacta' is adaptable to ambient outdoor humidity but will appreciate a moderate level of humidity if grown as a container plant, without the need for any special humidity modifications.
Suitable locationsIndoor

Life cycleWhite Fir 'Compacta', a cultivar of Abies concolor, begins its life cycle with seed germination after stratification, which occurs when seeds are exposed to cold temperatures to break dormancy. Emerging as seedlings, they are slow-growing and establish a root system. As saplings, they develop characteristic needles and a stout woody stem, adapting to cope with their environment. Maturing into adult trees, they develop a conical shape, produce cones, and become capable of sexual reproduction. The plant continues to grow and thicken for many years, becoming more resistant to environmental stress. As it ages, it eventually reaches senescence, where growth slows, and the plant may become more susceptible to disease, leading to decline and death.
PropogationPropogation time
Early Spring
The White Fir 'Compacta', a variation of Abies concolor, is best propagated through the process of grafting, particularly during the late winter months when the plant is still dormant. Grafting involves taking a shoot or scion of the 'Compacta' variety and attaching it to the rootstock of a more robust and generic Abies species. This method requires careful preparation of both the scion and rootstock, attained by making complementary cuts on both pieces and binding them together firmly until the graft union heals and the scion begins to grow independently. This approach leverages the strong root system of the rootstock, ensuring the 'Compacta's' desirable characteristics are reproduced in new plants. It requires patience and skill but is the primary method used among nursery professionals to maintain the specific traits of the White Fir 'Compacta'.
