Radiant Elegance: The Timeless Beauty and Care of Rosa ‘Gold Glow’
Rosa ‘Gold Glow’ is a distinguished hybrid tea rose, a category renowned for its large, single blooms atop long, sturdy stems, ideal for cutting. Introduced by Anthony Perry in 1959, this rose showcases the elegance and sophistication typical of hybrid tea roses. Rosa ‘Gold Glow’ is a result of crossbreeding between Rosa ‘Fred Howard‘ and R. ‘Sutter’s Gold‘, combining the best traits of both parent plants. The genus Rosa belongs to the family Rosaceae, which includes a wide variety of ornamental and fruit-bearing plants.
Description
Rosa ‘Gold Glow’ is a deciduous shrub that grows to a height of approximately 4 feet and a width of about 3 feet. The plant features an upright habit with numerous canes, making it a robust and vigorous grower. The leaves are dark green, glossy, and broad, providing a lush backdrop for the stunning blooms.
The flowers of ‘Gold Glow’ are the highlight of this plant. Each bloom opens from a long, pointed bud to a full, 4-inch diameter flower. Initially appearing as a golden yellow, the flowers gradually transition to a lemon yellow and finally to a creamy white at the outer petals. With a petal count exceeding 40, the blooms are very full and exhibit a moderate fragrance. ‘Gold Glow’ is a repeat bloomer, providing a continuous display of flowers from spring through fall.

Care Instructions for Rosa ‘Gold Glow’:
Light Requirements: Rosa ‘Gold Glow’ thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal growth and blooming.
Soil and pH: Prefers fertile, well-draining soil. The ideal soil pH ranges from moderately acidic (5.6 – 6.0) to slightly alkaline (7.4 – 7.8).
Watering: Water the rose when the top 1 to 2 inches of soil becomes dry. Apply water directly to the ground surrounding the rose, avoiding splashing on the leaves to prevent fungal diseases. Water early in the morning to allow foliage to dry before nightfall.
Fertilization: Fertilize with a 5-10-5 (nitrogen, phosphorus, potassium) granular fertilizer in the spring, just after new leaves appear. Apply 1 tablespoon of fertilizer around the plant, 4 to 6 inches away from the stem, and mix into the top 3 inches of soil. Repeat every six weeks during the growing season, stopping 6 to 8 weeks before the first average fall frost date.
Mulching: Spread a 2-3 inch layer of pine straw or wood chip mulch around the base of the rose, keeping it 6 inches away from the main stem. Replenish mulch each spring to help retain moisture and suppress weeds.
Pruning: Prune in late winter before new growth begins. Remove any dead, diseased, or damaged canes, cutting just above an outward-facing bud or lateral branch at a 45-degree angle. Remove any canes that cross or rub against each other. Cut back the remaining canes to a height of 18-20 inches.
Pest and Disease Control:
- Regularly check for pests such as spider mites, aphids, and thrips. Use a miticide for mites and insecticidal soap or horticultural oil for aphids and thrips.
- Monitor for fungal diseases like powdery mildew, black spot, and Botrytis blight. Apply fungicides as needed and ensure good air circulation around the plant.
Propagation
Rosa ‘Gold Glow’ can be propagated through stem cuttings. Here’s how:
- Select a Healthy Stem: Choose a stem that is healthy and free from disease, ideally one that has recently flowered.
- Cut the Stem: Cut a 6-8-inch section just below a leaf node.
- Prepare the Cutting: Remove the lower leaves, leaving the top few leaves intact.
- Rooting Hormone: Dip the cut end into a rooting hormone to encourage root development.
- Plant the Cutting: Insert the cutting into a well-draining potting mix. A mix of sand and peat works well.
- Provide Optimal Conditions: Place the pot in a warm, bright location with indirect light. Maintain a temperature between 65°F to 75°F (18°C to 24°C).
- Maintain Moisture: Keep the soil lightly moist but not waterlogged. Cover the pot with a plastic bag to create a humid environment.
- Transplant: Once roots have developed (usually within 6-8 weeks), transplant the new plant into a larger pot or directly into the garden.
