So how to cultivate Rhododendron tomentosum? It involves soil, lighting, temperature, watering, fertilizing, pruning, and pest and disease control. Let's take a closer look.
1. Soil
It's best to choose a loose, well-draining, acidic, and fertile soil for planting. The cultivation soil for Rhododendron tomentosum can be mixed in a ratio of 4:2:1:1:1 with humus soil, old potting soil, sandy soil, charred soil, and sawdust. An appropriate amount of cake fertilizer can be added to increase the soil's nutritional value.
2. Lighting
rhododendron tomentosum loves light and requires ample lighting. However, the plant should not be exposed to strong sunlight for too long. It is best to care for it in a semi-shaded and sunny environment like a balcony or windowsill.
3. Temperature
Rhododendron tomentosum prefers a cool and pleasant growing environment, with the most suitable temperature range being 15°C to 28°C. It can tolerate low temperatures, surviving in temperatures as low as -8°C, but it is not heat-tolerant. When temperatures are too high, it is important to cool the plant down.
4. Watering
Watering for Rhododendron tomentosum should be done when the soil is dry, keeping an eye on the dryness of the cultivation soil. When the soil is dry, watering is necessary. During the summer, when temperatures are high, watering can be done once a day. In winter, reduce the watering frequency to about once every 4-5 days.
5. Fertilizing
Fertilizing for Rhododendron tomentosum should be done in small amounts multiple times. Be careful not to over-fertilize or use a high concentration of fertilizer, as this can have adverse effects on the plant. Generally, during the growing season, fertilize once every half month, and once before and after flowering. No fertilizing is needed when winter arrives.
6. Pruning
During the growing period, it's important to pinch back and prune Rhododendron tomentosum to promote its growth. When pruning, remove the weak, diseased, and dead branches to ensure the supply of nutrients to the main branches and leaves.
7. Pest and Disease Control
Rhododendron tomentosum is susceptible to pests and diseases, so it is important to prevent and treat them in a timely manner. Pests and diseases such as brown spot, root rot, or red spider mites can severely threaten the normal growth of the plant. It is necessary to detect and treat these issues early, and use medication when the situation is severe.
