WaterEastern arborvitae, commonly known as Amber Glow, should be watered deeply and thoroughly, providing about 1 gallon of water per foot of plant height each week. Newly planted Amber Glow trees need to be kept consistently moist, so watering may be necessary 2 to 3 times a week, depending on the climate and soil drainage. It's important to ensure water reaches the root zone, which can be several inches below the soil surface. Once established, Amber Glow is more drought-tolerant and may require watering every other week, particularly during dry spells. Overwatering can be as harmful as underwatering, so it is essential to check the soil moisture before watering.
LightThe Amber Glow, or eastern arborvitae, thrives in full sun to partial shade. The ideal location for planting is one that receives at least 6 hours of direct sunlight daily, though it can tolerate some light afternoon shade. Avoid deeply shaded spots, as too little light can impede growth and weaken the plant.
TemperatureEastern arborvitae, or Amber Glow, is hardy to a range of temperatures and can survive minimum temperatures down to about -40 degrees Fahrenheit. The ideal growing conditions are generally between 40 and 70 degrees Fahrenheit. It is capable of withstanding temperatures up to 90 degrees Fahrenheit, but it prefers cooler climates and may require extra care in hotter regions.
PruningPruning the eastern arborvitae, or Amber Glow, is primarily done to maintain its desired shape and remove any dead or damaged branches. Pruning should be done in the early spring or late fall, and it can be pruned annually if needed. It's important not to prune too heavily, as these trees do not regenerate well if cut back to old wood.

Life cycleThuja occidentalis 'Amber Glow', commonly known as the American arborvitae or Amber Glow arborvitae, begins its life as a seed, typically germinating in moist soil conditions within a partially shaded area. Seedlings emerge and establish themselves with a robust root system before developing into juvenile plants, where characteristic scale-like leaves start to appear. As it matures into an adult, it undergoes vegetative growth, forming a dense, pyramidal shape with rich green to amber foliage that intensifies in color during the colder months. Throughout its life, the Amber Glow arborvitae may produce small cones after reaching maturity, which then disperse seeds for reproduction. The plant continues to grow and thicken, often living for several decades, and can withstand a range of temperatures and soil conditions once fully established. Eventually, like all living organisms, the arborvitae will enter senescence, experiencing reduced vigor and gradually declining until it dies.
PropogationPropogation time
Late winter
Thuja occidentalis 'Amber Glow', commonly known as the American arborvitae, is typically propagated through semi-hardwood cuttings. The best time to propagate the American arborvitae via cuttings is in late summer, as this allows the plant material to have the ideal balance of maturity and growth potential. To propagate, a cutting between 4 and 6 inches long should be taken from the current year's growth. The lower leaves of the cutting are removed, and the cut end is often dipped in a rooting hormone to enhance the chances of root development. Afterward, the cuttings are inserted into a well-draining growing medium. It usually takes several weeks to a few months for roots to adequately develop. The cuttings should be kept in a humid environment with indirect light until the roots are established, after which they can be transplanted into larger pots or directly into the garden.
