WaterRhododendrons, including 'Percy Wiseman', require consistent moisture and should be watered when the top inch of soil feels dry to the touch. In general, an established plant needs about one inch of water per week, either from rainfall or irrigation. During the growing season, this might mean watering with approximately 1-1.5 gallons per week, depending on weather conditions. Be careful not to overwater, as Rhododendrons are prone to root rot if left in waterlogged soil. In hot, dry periods, you may need to water twice a week, but always check the soil moisture first.
LightRhododendrons, like 'Percy Wiseman', thrive in spots with dappled shade. They do well in an area that receives morning sunlight and afternoon shade, or filtered light under the canopy of tall trees. Direct hot afternoon sun can damage the leaves and flowers, so it's important to avoid overly sunny spots, especially in the warmer months.
TemperatureRhododendron 'Percy Wiseman' can tolerate a wide range of temperatures, but thrives in areas where the average temperature is between 50°F and 70°F. It can survive minimum temperatures of around -5°F but may suffer cold damage if not protected. Heat above 90°F can also stress the plant if not adequately shaded and watered.
PruningPruning Rhododendron 'Percy Wiseman' is typically done to maintain shape, remove dead or diseased wood, and promote vigorous growth. It's best to prune right after blooming ends in spring or early summer, as the plant sets buds for next year shortly after. Cut just above the growth joints, and avoid heavy pruning, which can reduce flowering the following season.
CleaningAs needed
SoilRhododendrons require well-draining, acidic soil with a pH between 4.5 to 6.0. A good mix for Rhododendron 'Percy Wiseman', commonly known as Rhododendron, would be equal parts peat moss, pine bark, and perlite or coarse sand to ensure proper drainage and aeration.
RepottingRhododendrons, including 'Percy Wiseman', usually require repotting every 2 to 3 years or when they become root-bound. Repot in spring or early fall to minimize stress on the plant.

Life cycleRhododendron 'Percy Wiseman' begins its life cycle when a seed, often resulting from cross-pollination by insects, germinates in well-drained, acidic soil with partial shade. The seedling emerges and develops into a young plant, producing its first leaves and establishing a root system, typically within a few weeks to months, depending on environmental conditions. As it matures, the plant undergoes vegetative growth, forming a woody structure and evergreen leaves, becoming a shrub over several years. Throughout its life, 'Percy Wiseman' undergoes annual cycles of flowering, typically in late spring to early summer, with the blooms ranging in color from peach to pink, attracting pollinators and sometimes leading to seed formation if conditions permit. After the flowering period, the plant focuses on strengthening and expanding its foliage, ensuring its survival through winter. The Rhododendron can live for many years, sometimes decades, continuing its cycle of growth, flowering, and dormancy.
PropogationPropogation time
Spring-Early Summer
Rhododendron 'Percy Wiseman', commonly known as a type of rhododendron, is best propagated using semi-hardwood cuttings. Semi-hardwood cuttings are taken from the current year's growth that has begun to mature and harden off but is not yet completely woody. This typically occurs in late summer, often from late July to September. To propagate, cut a 4 to 6-inch section (approximately 10 to 15 cm) from a healthy branch, ensuring at least two sets of leaves are present. Remove the lower leaves and dip the cut end into rooting hormone powder to encourage root development. The cutting should then be placed in a moistened mix of half peat and half perlite or a similar rooting medium. Ensuring adequate humidity and warmth, the cuttings will often root within a couple of months, after which they can be transplanted into individual pots to grow on before being planted out.
