big-leaved rhododendron

Big-leaved rhododendrons (Rhododendron 'Cynthia') should be watered regularly to ensure healthy growth. Water when the top inch or 2 of soil is dry, but do not let the soil dry out completely. When watering, use lukewarm water, and water until excess water drains from the pot. In the summer months, water the plant twice a week, and during the winter months, reduce watering to once every 2 weeks. Additionally, fertilize your rhododendron every couple of weeks during the summer months with a fertilizer specifically designed for rhododendrons.

Big-leaved rhododendron (Rhododendron 'Cynthia') occurs naturally in the damp, temperate forests of the Himalayan Mountains, so it prefers bright, indirect sunlight. The plant should be placed in a location that receives morning sun and afternoon shade or in a spot that gets filtered light throughout the day. During winter, they should receive around 4 hours of bright light a day and in summer they can tolerate up to 8 hours of direct sunlight. Too much sun can cause leaf scorching, so it is important not to expose them to extreme sun or heat stress. Therefore, direct light should be avoided if possible.

Big-leaved rhododendrons (Rhododendron 'Cynthia') should be pruned in late winter or early spring, just before fresh growth begins. Start pruning by removing any dead, diseased, or crossed branches. Also remove any branches that are weak or too close together. Cut away any branch that rubs against or interferes with another. Pruned stems should be cut back to an outward facing bud or branch junction. Avoid cutting into old wood, as this will not promote regrowth. You should selectively prune about 1-third of the branches from each shrub. When finished be sure to apply an organic mulch cover at the base of the plant. This will help to conserve moisture and reduce weeds.
