What You’ll Need to Grow Yellow Dahlias
Plant Care Requirements
Light: Dahlias thrive in full sun, needing at least 6-8 hours of sunlight daily.
Water: Keep the soil consistently moist but not soggy. Overwatering can lead to root rot.
Soil: Use well-draining, fertile soil rich in organic matter. A pH of 6.5–7.0 is ideal.
Temperature: Dahlias grow best in temperatures between 60–75°F (16–24°C).
Humidity: Moderate humidity levels are sufficient; avoid overly damp conditions.
Fertilizer: Feed with a balanced 10-10-10 fertilizer every two weeks during the growing season.
How to Plant Yellow Dahlias
Step 1: Choose the Right Location
Select a sunny spot in your garden with good air circulation.
Step 2: Prepare the Soil
Enrich the soil with compost or well-rotted manure for added nutrients. Ensure it drains well to prevent waterlogging.
Step 3: Plant the Tubers
Dig a hole about 4–6 inches deep. Place the dahlia tubers horizontally, with the eye (growth point) facing up.
Cover the tubers with soil, leaving about 1–2 inches of soil above the crown.
Step 4: Water Gently
Water the tubers lightly after planting. Avoid overwatering until the shoots emerge.
Step 5: Support the Stems
As dahlias grow tall, insert stakes or supports to prevent the stems from bending under the weight of the blooms.
Tips for Growing Stunning Yellow Dahlias
Pinch Early Growth: Once the plants reach about 12 inches tall, pinch off the top inch of growth to encourage bushier plants and more blooms.
Deadhead Regularly: Remove spent flowers to promote continuous blooming throughout the season.
Mulch for Moisture: Apply a layer of organic mulch around the base of the plant to retain soil moisture and suppress weeds.
Protect from Pests: Watch out for slugs, aphids, and spider mites. Use insecticidal soap or neem oil as needed.
Dig and Store Tubers in Winter: In colder climates, dig up the tubers after the first frost. Let them dry, then store in a cool, dry place until spring.
