Stock flowers, or Matthiola incana, renowned for their spicy, sweet fragrance, are a splendid addition to any garden. These native European and Asian Minor plants, also known as Gillyflower, offer a wide range of bright colors and make excellent cut flowers for indoor arrangements. This guide provides a detailed walkthrough for growing these lovely flowers, from soil preparation to care and maintenance.
Key Takeaways
- Soil Preparation: Ensure well-draining soil with neutral pH.
- Germination: Maintain even moisture but avoid oversaturation.
- Seedling Care: Thin out seedlings for optimal growth.
- Location: Choose sunny spots with at least 3-6 hours of sunlight.
- Planting: Use both seeds and seedlings for varied success.
- Watering and Feeding: Regular watering and monthly fertilization.
- Pest Management: Be vigilant against aphids and other pests.
Preparing the Soil for Stock Flowers
Matthiola incana thrives in soil that is rich and well-draining with a neutral pH. The first step to successful growth is preparing your garden bed. Work the soil to a depth of 8-10 inches, breaking up large clods to achieve a smooth consistency. This preparation ensures that your stock flowers have the right foundation to flourish.
Ideal Soil Conditions
- Texture: Loose and well-draining
- pH Level: Neutral
- Depth: 8-10 inches
Germination of Stock Flowers
The germination process is crucial for healthy stock flowers. Sow the seeds shallowly, barely covering them with 1/8 inch of fine soil. It’s essential to maintain even moisture during this stage but be careful not to oversaturate the soil.
Germination Tips
- Seed Depth: 1/8 inch
- Moisture: Even but not oversaturated
- Germination Time: Approximately 7-10 days
Seedling Care for Stock Flowers
Once the seedlings have sprouted two sets of true leaves, it’s time to thin them to one every 9-18 inches. This spacing allows each plant enough room to develop fully.
Seedling Spacing
| Plant Stage | Spacing |
| Seedlings | 9-18 inches |
Where to Grow Stock Flowers
Stock flowers need full to partial sunlight to thrive. A location that receives at least three hours of sunlight daily is ideal, but six or more hours is preferable. Avoid places blocked by walls, fences, or other plants.
Sunlight and Location Requirements
- Sunlight: Full to partial (3-6 hours minimum)
- Avoid: Areas blocked by structures or other plants
How to Plant Stock Flowers
Stock flowers can be grown from both seeds and seedlings. If starting from seedlings, plant them at the same depth they were in their starter pots. For seeds, sow indoors early in the season and cover lightly with soil.
Planting Techniques
- From Seedlings: Plant at the same depth as in starter pots
- From Seeds: Sow indoors, cover lightly with soil
Caring for Stock Flowers
Stock flowers are relatively low-maintenance once established. They require about an inch of water per week, with careful attention to not water the leaves directly to prevent fungal growth. A general-purpose fertilizer should be applied monthly.
Watering and Feeding
- Water: About 1 inch per week
- Fertilizer: Monthly with a general-purpose fertilizer
Pest Management in Stock Flowers
Aphids and other pests can pose a threat to your stock flowers. Regular inspection and prompt treatment with neem oil or a combination of soap and water can help manage these pests.
Common Pests
- Aphids: Treat with neem oil or soap and water mixture
