Rhododendron
Rhododendrons are popular shrubs known for their vibrant blooms and lush foliage. Gardeners prize them for adding color to partial shade gardens while providing year-round structure.

🌾 Sow directly in the garden — Azalea is not usually started indoors.
Do not sow seeds for Rhododendrons; instead, transplant young nursery-grown plants outdoors after all danger of frost has passed and the soil is workable.
Soil, care & harvest
Prepare acidic soil with a pH between 4.5 and 6.0, as these plants thrive in such conditions. Since Rhododendrons are established shrubs rather than sown seeds, do not sow them relative to the last frost. Instead, purchase young plants or start from cuttings indoors weeks before your local planting window to ensure a strong root system for transplanting.
Space plants 3 to 6 feet apart to allow proper air circulation and growth. Provide moderate water consistently, ensuring the soil stays moist but not waterlogged. Apply mulch around the base to retain moisture and regulate temperature, while feeding with an acid-loving plant fertilizer during the growing season.
Watch for pests like aphids or spider mites, which can be prevented by regular inspection and good air circulation. Diseases such as root rot may occur if drainage is poor; ensure proper soil pH to mitigate risks. As an ornamental shrub, there is no harvest time in days; instead, enjoy the spring blooms when they naturally appear.
