As needed
  • water dropWater

    The Campbell's magnolia needs consistent moisture but does not tolerate standing water. Young trees should be watered deeply at least once a week, providing around 15 to 20 gallons per watering, depending on soil type and weather condition. Mature trees can be watered less frequently; during dry spells, a thorough soaking every two to three weeks may suffice, ensuring the water penetrates deeply into the root zone. During the winter, watering should be reduced to prevent cold damage to the roots. It is important not to overwater, as this could lead to root rot.

  • sunLight

    The Campbell's magnolia thrives best in full sun to partial shade. Ideally, planting it in a spot where it can receive at least four hours of direct sunlight followed by lightly dappled shade would be most beneficial for the plant's growth and flowering. Avoid deep shade locations, as this can impede the magnolia's health and flowering capability.

  • thermometerTemperature

    Campbell's magnolia prefers a temperate climate with temperatures typically ranging from 20°F to 85°F. It is hardy in USDA zones 7 to 9, which means it can survive minimum winter temperatures of 0°F. The ideal temperature range for this magnolia is between the upper 60s and mid-70s Fahrenheit during its growing season; however, it is adaptable to slightly warmer conditions as long as the root zone remains cool and moist.

  • scissorsPruning

    Campbell's magnolia requires minimal pruning, primarily to remove any dead or diseased wood and to shape the tree as desired. The best time for pruning is late winter or early spring before new growth starts. Pruning should be done sparingly, as the plant heals slowly from cuts; remove only what is necessary to maintain the health and appearance of the tree. Pruning annually or biennially is typically sufficient.

    As needed

  • bambooSoil

    Campbell's Magnolia prefers slightly acidic to neutral soil with a pH of 5.5 to 7.0. The best soil mix should be rich, well-draining, and loamy, with a good amount of organic matter like compost or leaf mold to retain moisture and provide nutrients.

  • plantRepotting

    Campbell's Magnolia generally does not need to be repotted often as it is typically grown as an outdoor tree. However, if grown in a container, it should be repotted every 2 to 3 years to prevent root-bound conditions and to replenish the soil.

  • water dropsHumidity & Misting

    Campbell's Magnolia thrives best in moderate to high humidity levels, typical of its natural forested habitat. Maintaining ambient humidity around 50-60% is ideal for its growth.

  • circleLife cycle

    The life cycle of Magnolia campbellii, commonly known as Campbell's magnolia, begins with seed germination, which requires a period of cold stratification to break dormancy. Once germinated, the seedling grows into a young plant, establishing roots and producing its first set of leaves. As it matures into an adult, it develops a woody trunk and branches, forming the characteristic large, broadly conical to rounded crown. After reaching maturity, which can take several years, Magnolia campbellii produces large, showy flowers, typically in pink or white, signaling its readiness for reproduction. Following pollination, usually by beetles, it develops into fruiting bodies that release seeds, completing the cycle as these seeds disperse, potentially giving rise to new plants. Throughout its lifetime, which may span many decades, the tree undergoes periodic growth and regenerative phases, with seasonal leaf drop and regrowth in temperate climates.

    • Propogation time

      Spring to Summer

    • Propogation: The most popular method of propagating the Himalayan magnolia, or Magnolia campbellii, is by grafting, particularly during the late winter or early spring when the plant is not in active growth. In this process, a piece of stem from a mature magnolia with desirable characteristics is attached to the rootstock of another plant. The grafted union must be kept under high humidity and ideally at a temperature around 55-70 degrees Fahrenheit (around 12-21 degrees Celsius) to encourage successful healing and union. The grafted plants are usually kept in a mist bed with bottom heat to maintain optimal conditions. It can take several weeks to months for the graft to heal and start growing as a new plant. This method is preferred as it helps to maintain the specific qualities of the parent plant.
