WaterMakino Rhododendron should be watered thoroughly once a week during the growing season, ensuring that water reaches the root zone. In hot or windy weather, increase watering to twice a week, but avoid over-watering to prevent root rot. During winter, reduce watering to every other week or less, as the plant requires less moisture. The soil should be kept moist but not soggy, and it's typically recommended to provide about 1 inch of water per watering session.
LightMakino Rhododendron thrives in partial shade, ideally receiving filtered sunlight or morning sun followed by afternoon shade. The best spot for this plant is one that avoids the intense heat of the midday sun, which can scorch the leaves, while still providing enough light for the plant to produce its flowers.
TemperatureThe ideal temperature range for Makino Rhododendron is between 50°F and 75°F. They can survive a minimum temperature of about 20°F, provided they are protected from harsh winter winds. During the summer, it is essential that they are not exposed to temperatures above 80°F for prolonged periods, as this can cause stress to the plant.
PruningPrune Makino Rhododendron in late winter or early spring to maintain shape and encourage bushier growth. Deadheading spent flowers after blooming will promote better blooms the following season. Annual pruning of dead or crossing branches will also help maintain plant health. Limit pruning to about one third of the plant each year to avoid overstressing the plant.
CleaningAs needed
SoilMakinoi Rhododendron thrives in acidic soil with a pH between 4.5 to 6.0. The best soil mix is a combination of peat moss, pine bark, and perlite or coarse sand to ensure good drainage and aeration. A top layer of pine needles or leaf mulch can help maintain soil acidity and moisture.
RepottingMakinoi Rhododendron generally requires repotting every 2 to 3 years. The best time for repotting is during late winter or early spring just before the growth season starts. Ensure that the new pot has proper drainage to prevent root rot.
Humidity & MistingMakinoi Rhododendron prefers moderate to high humidity levels. Aim for a humidity level of around 50-60% for optimal growth. If the air in your home is dry, use a humidifier or place a water tray near the plant to increase humidity.
Suitable locationsIndoor
Ensure bright, indirect light, acidic soil, and moderate humidity for indoor Makinoi Rhododendron.
Outdoor

Life cycleRhododendron makinoi, commonly known as Makino's Rhododendron, begins its life cycle when its seeds germinate in a moist, well-drained acidic soil, typically under the shade of trees. The seedlings grow slowly, developing a robust root system and evergreen foliage characteristic of rhododendrons. As a juvenile, Makino's Rhododendron gradually forms a woody stem and reaches maturity over several years, during which it begins to produce large, showy flowers that are usually white to pale pink with a distinctive reddish-brown dorsal blotch. The flowering stage occurs in spring, and after pollination by insects, the plant produces dry, dehiscent capsules that release numerous small seeds. These seeds, once dispersed often by wind, can lead to the establishment of new plants if they land in suitable growing conditions. Makino's Rhododendron can live for many years, with some specimens surviving for several decades, continuously going through cycles of growth, flowering, and seed production.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagating Rhododendron makinoi, commonly known as Makino's Rhododendron, is through semi-hardwood cuttings. This technique involves taking cuttings from the plant during the summer when the new growth has begun to mature and harden slightly. Typical cuttings should be about 4 to 6 inches long. The leaves on the lower half of the cutting are removed and the bottom end is dipped in rooting hormone powder to encourage root development. Afterward, the cuttings are inserted into a potting mix of equal parts peat and perlite. The pot should then be placed in a humid environment with dappled sunlight until the roots have formed, which can take several weeks. Maintaining adequate moisture levels during this time is key to successful propagation.
