Mom’s Special is a stunning variety of dahlia known for its large, showy blooms with a unique blend of colors, ranging from soft pinks to deep purples, often with a lighter, more delicate center. Its petals can sometimes have a subtle gradient effect, making it a striking addition to gardens, floral arrangements, or containers. Like most dahlias, Mom’s Special offers an abundant display of flowers throughout the summer and fall, making it a favorite for gardeners looking to add vibrant color and beauty to their landscapes.

Below is a comprehensive care guide for growing and maintaining the Mom’s Special dahlia.

1. Ideal Growing Conditions

Dahlias are native to warmer climates and thrive under certain growing conditions.

Key Growing Conditions:

• Light: Dahlias, including Mom’s Special, require full sun to grow and bloom at their best. Aim for at least 6-8 hours of direct sunlight each day. Adequate sunlight will ensure that the plant produces vibrant blooms and strong growth.
• Temperature: Dahlias are best suited to USDA hardiness zones 8-11. They love warm temperatures and do not tolerate frost. During the growing season, temperatures between 65°F to 75°F (18°C to 24°C) are ideal. If you live in a cooler zone, you may need to dig up the tubers in the fall and store them over the winter.
• Humidity: While dahlias appreciate moderate humidity, they do not fare well in overly wet or damp conditions. Good air circulation around the plants is essential to prevent fungal diseases.

2. Soil and Planting Requirements

The right soil is essential for healthy growth and abundant flowering.

Soil Requirements:

• Well-Draining, Fertile Soil: Mom’s Special dahlias require well-draining soil that is rich in organic matter. They prefer soil that is slightly acidic to neutral, with a pH between 6.0 and 7.0.
• Loamy Soil: A loamy or sandy soil texture is ideal, as it allows water to drain away efficiently while retaining enough moisture for the plant’s roots.
• Soil Amendments: If your soil is heavy clay or compacted, improve drainage by amending it with compost, peat moss, or well-rotted manure. This will not only improve drainage but also provide additional nutrients for the plant.

Planting Tips:

• Planting Depth: Dahlias are typically planted from tubers, and the tuber should be planted about 4-6 inches deep into the soil, with the “eyes” (small growth buds) facing upwards. Make sure there is enough space around the tuber for the roots to grow, about 12-18 inches apart for larger varieties like Mom’s Special.
• Spacing: Plant dahlias at least 12-18 inches apart to allow them room to grow and spread. Crowded plants can lead to poor air circulation and may be more susceptible to diseases.
• Timing: In cooler climates, wait until after the last frost before planting the tubers. In warmer regions, you can plant them as early as spring, once the soil warms up to around 60°F (15°C).

3. Watering

Consistent and proper watering is essential for dahlias to flourish.

Watering Guidelines:

• Moderate Watering: Mom’s Special dahlias like consistently moist soil but don’t tolerate soggy conditions. Water the plant deeply to ensure the roots receive moisture, but allow the soil to dry out slightly between waterings. Avoid overhead watering, as it can lead to fungal diseases.
• Watering Schedule: During the growing season, water your dahlias regularly, particularly during dry spells. However, be cautious not to overwater, as this can cause the tubers to rot. Ensure the water drains well from the soil to avoid waterlogging.
• Morning Watering: Water in the morning to allow the foliage to dry before evening. Wet foliage overnight can lead to mold and mildew problems.

4. Fertilizing

Fertilizing dahlias promotes healthy growth and vibrant blooms, but the right balance is essential.

Fertilizing Tips:

• Balanced Fertilizer: Use a balanced, slow-release fertilizer with equal parts nitrogen, phosphorus, and potassium (e.g., 10-10-10). This will support overall plant health and encourage strong root and flower development.
• Low Nitrogen Fertilizer for Blooming: After the plant has established itself and started to grow, switch to a fertilizer with a lower nitrogen content and higher phosphorus and potassium levels (e.g., 5-10-10). This will help promote flower production instead of excessive leafy growth.
• Fertilizing Schedule: Start fertilizing in early spring when the plant is actively growing and apply it once a month throughout the growing season. Do not fertilize in late fall, as the plant is preparing for dormancy and does not need additional nutrients.

5. Pruning and Maintenance

Pruning is important to maintain a neat shape and encourage more blooms.

Pruning Tips:

• Pinching for Bushier Growth: When the plant is young, pinch back the tips of the stems to encourage branching and a fuller plant. This will help produce more flowers as the plant matures.
• Deadheading: Remove spent flowers regularly to encourage the plant to produce more blooms. Snip off flowers once they start to fade, cutting back to the first set of healthy leaves.
• Staking: As Mom’s Special dahlia grows, it may need support to prevent the tall stems from breaking under the weight of the flowers. Use sturdy stakes or plant supports to keep the stems upright and the flowers looking neat.
• Cutting Back: At the end of the growing season, once the first frost has passed and the plant begins to die back, trim the stems back to around 4-6 inches above the ground.

6. Pests and Diseases

While Mom’s Special dahlia is generally resistant to many pests, it can still be affected by a few common garden issues.

Common Pests:

• Aphids: These tiny insects can infest the stems and leaves, causing yellowing or curled leaves. They can be controlled by spraying with insecticidal soap or a strong jet of water.
• Slugs and Snails: These pests can chew holes in the leaves, especially during damp weather. Use slug bait or create barriers around the plants to deter them.
• Japanese Beetles: These beetles feed on the leaves and flowers of dahlias, leaving behind unsightly holes. Handpick them or use insecticides as needed.

Common Diseases:

• Powdery Mildew: This fungal disease appears as a white, powdery coating on the leaves. It thrives in humid conditions and can be managed by ensuring good air circulation, watering at the base of the plant, and applying fungicides if necessary.
• Botrytis Blight: Also known as gray mold, this disease affects flowers and foliage, causing brown or gray spots. Remove infected flowers and leaves and treat with fungicides to prevent the spread of the disease.
• Tubers Rot: Overwatering or poorly drained soil can cause the tubers to rot. Avoid excessive watering and make sure the soil drains well.

7. Winter Care

In regions with cold winters, Mom’s Special dahlias are often dug up to overwinter indoors, as they cannot survive frost.

Winter Care Tips:

• Digging Up Tubers: After the first frost, cut the plant back to about 4-6 inches above the ground and carefully dig up the tubers. Gently shake off any soil and let them dry out in a cool, dry location for a few days.
• Storage: Once the tubers are dry, store them in a cool, dark place (around 40-50°F or 4-10°C). You can store them in boxes filled with peat moss, sawdust, or dry sand to prevent them from drying out completely.
• Spring Planting: In the spring, when the danger of frost has passed, replant the tubers in well-drained soil, following the same planting instructions as outlined earlier.

8. Propagation

Dahlias can be propagated through division of the tubers, which should be done in the spring.

Propagation by Division:

1. Dig up the tubers in the spring, when they start sprouting.
2. Gently separate the tubers, ensuring each division has at least one eye (growth bud) and part of the root system.
3. Replant the divisions as you would with a whole tuber, following the planting guidelines.

Conclusion

Mom’s Special dahlia is a show-stopping variety with its vibrant, colorful blooms that can add drama and beauty to any garden. With the right care—adequate sunlight, well-draining soil, consistent watering, and regular pruning—this dahlia will reward you with a stunning display of flowers all season long. Whether planted in garden beds, containers, or used in floral arrangements, Mom’s Special is sure to be a favorite for many seasons to come.
