Why Growing Blue Mirror Delphiniums is Worth It

Growing Blue Mirror Delphiniums is worth it because they are one of the most beautiful flowers you can grow in your garden.

How to Grow Blue Mirror Delphiniums

1. Start with the Right Seeds

When starting Blue Mirror Delphiniums from seeds, ensure you get high-quality seeds from a reliable source. Once you have your seeds, start by sowing them indoors. Fill germination trays with seed-starting mix and press the seeds in gently, ensuring they don't get covered with too much soil. Maintain consistent moisture levels and temperature, typically between 65-70 °F. Once the seedlings have grown two or three leaves, it's time to transplant them.

2. Soil Preparation

Blue Mirror Delphiniums prefer fertile, well-draining soil. Before planting, add organic matter such as compost and work it into the top 12 inches of the soil. Doing this helps improve the soil's texture and provide extra nutrients to the plant.

3. Choosing the Best Location for your Blue Mirror Delphiniums

When selecting a location to plant your Blue Mirror Delphiniums, choose an area that gets ample sunlight. The plant requires at least six hours of direct sunlight daily. Additionally, consider planting them in an area where they are not exposed to strong winds, which can damage the tall stems.

4. Planting and Watering

Plant your Blue Mirror Delphiniums by digging a hole twice the size of the root ball. Place the plant in the hole and cover with soil, ensuring you don't bury the stem any deeper than it was already growing. Water the plant deeply, making sure to keep the soil consistently moist but not waterlogged. In dry conditions, water the plant weekly or more frequently if required.

5. Care and Maintenance

Once established, Blue Mirror Delphiniums require less maintenance, but regular care ensures a healthy plant. Remove deadheads to encourage new flower production and prune after flowering, cutting back to the base of the plant. If necessary, stake the stems to keep them from bending or breaking. Additionally, mulching around the plant helps retain soil moisture and prevent weeds.

Best Soil for Blue Mirror Delphiniums

1. pH Level

Blue Mirror Delphiniums prefer slightly acidic soil with a pH of 6.0–7.0. Use a soil testing kit or send a sample to a local lab to determine the soil's acidity levels. If the pH is not within the desired range, amend the soil with sulfur, epsom salts, or lime.

2. Organic Matter

In addition to ensuring the soil's pH level is suitable, adding organic matter such as compost also helps improve soil quality. This enhances the soil's water-holding capacity, provides nutrients, and promotes healthy microbial activity.

3. Drainage

Proper drainage is essential for Blue Mirror Delphiniums, as they are susceptible to root rot if the soil remains waterlogged. To enhance drainage, mix sand or grit into the soil, and avoid planting them in low-lying or compacted soil areas.

Blue Mirror Delphiniums are a beautiful addition to any garden. With the right soil preparation and care, they can thrive in almost any environment. They require minimal maintenance once established, making them ideal for gardeners looking for low-maintenance yet visually stunning plants. If you're looking for a flower to add color and life to your outdoor space, Blue Mirror Delphiniums might just be the right choice for you.
