Mignonette (or Reseda as it’s known) is a charming flowering plant. It may have a fairly modest appearance but it’s got a fantastic fragrance.
And that makes it a wonderful addition to any garden, especially if you’re aiming to attract pollinators like bees and butterflies.
So if you’re looking to grow some Mignonette this guide will give you all the information and tips you need.
Understanding Mignonette
Plant Characteristics
Mignonette typically grows up to 12-24 inches tall. The flowers might not be the showiest in terms of color but their delicate white, green or yellowish blooms have a wonderful scent that’s pretty hard to resist.
Historical Significance
Mignonette originates from the Mediterranean region and has a surprisingly full history. It was widely cherished in ancient Egypt and later spread across Europe valued both for its fragrance and medicinal properties.
Getting Started with Mignonette
Choosing the Right Location
Mignonette thrives in full sun to partial shade. It’s not too fussy about soil but prefers well-draining conditions. So that means you want to choose a spot that has good air circulation to prevent mildew.
Soil Preparation
Before planting enrich your soil with organic matter. Here’s a quick soil prep checklist:
- Loosen the soil to a depth of 12 inches.
- Incorporate compost or well-rotted manure.
- Ensure the pH is slightly alkaline (around 7.0 to 8.0).
Understanding Soil Types
Mignonette is adaptable but thrives best in well-draining, slightly alkaline soils. Here’s a closer look at soil types:
- Clay Soil: Heavy and can retain too much water. Improve by adding sand and organic matter to increase drainage.
- Sandy Soil: Drains quickly but may not retain enough moisture or nutrients. Introduce some compost to improve water retention and fertility.
- Loamy Soil: Ideal for most plants, including mignonette. It balances drainage and nutrient availability. Adding organic matter further improves its properties.
Testing and Amending Soil pH
Mignonette prefers a pH of 7.0 to 8.0. To test your soil:
- Use a home soil test kit available at garden centers.
- Collect soil samples from different parts of your garden for an accurate reading.
If your soil is too acidic (below pH 7):
- Add lime to raise the pH.
- Follow the instructions on the lime packaging for proper application rates.
If the soil is too alkaline (above pH 8):
- Add some elemental sulfur or peat moss to lower the pH.
Improving Soil Structure
Even well-draining soils can benefit from amendments to improve structure and fertility. Here’s how:
- Compost: Adds organic matter, improves soil structure and provides nutrients.
- Manure: Well-rotted manure enhances fertility and soil texture.
- Perlite or Vermiculite: Improves aeration and drainage, especially useful in heavier soils.
Planting Mignonette
You can start mignonette from seeds or transplants.
Starting Mignonette from Seeds
Starting from seeds is cost-effective and allows for a larger number of plants.
Sowing Indoors
- Sow seeds 6-8 weeks before the last expected frost.
- Use seed trays filled with a light, well-draining seed starting mix.
- Press seeds lightly into the soil surface without covering them as they need light to germinate.
- Keep the soil consistently moist but not waterlogged. A spray bottle can help maintain moisture levels without disturbing the seeds.
- Place trays in a warm, bright location. Germination typically occurs within 10-14 days.
Sowing Outdoors
- Wait until the last frost has passed and the soil has warmed up.
- Choose a sunny to partially shaded location with well-draining soil.
- Scatter seeds on the soil surface and lightly press them in.
- Keep the soil moist until seeds germinate.
Transplanting Seedlings
Once your seedlings are ready to move outdoors:
- Harden off seedlings by gradually introducing them to outdoor conditions over a week.
- Transplant seedlings into the garden when they are 3-4 inches tall.
- Space plants 8-12 inches apart to allow for proper growth and air circulation.
Care and Maintenance
Watering Practices
Proper watering is crucial for healthy mignonette growth.
- Establishment Phase: Water newly planted seeds or seedlings consistently to keep the soil moist but not soggy. This helps establish a strong root system.
- Mature Plants: Once established mignonette prefers regular watering but can tolerate short dry spells. Water deeply once or twice a week depending on weather conditions.
- Watering Technique: Use a soaker hose or drip irrigation to deliver water directly to the soil, reducing the risk of fungal diseases.
Fertilizing
While not heavy feeders a light application of a balanced fertilizer can boost growth. Apply once at planting and again mid-season if the plants look like they need a pick-me-up.
- At planting time mix a balanced, slow-release fertilizer into the soil.
- Apply a liquid fertilizer every 4-6 weeks during the growing season if plants appear to need extra nourishment.
- Avoid over-fertilizing as this can lead to excessive foliage growth at the expense of flowers.
Pruning and Deadheading
Pruning is essential to keep your mignonette blooming beautifully:
- Regularly remove spent flowers (deadheading) to encourage continuous blooming.
- Use sharp, clean scissors or pruners to make clean cuts.
- In late fall cut back the plants to about 6 inches to prepare them for winter and encourage healthy growth in the next season.
Dealing with Pests and Diseases
Common Pests
Though relatively good at resisting pests a few insects can pose problems:
- Aphids: Tiny, sap-sucking insects that can cause leaf curling and stunt growth. Control with insecticidal soap or by introducing natural predators like ladybugs.
- Spider Mites: Microscopic pests that cause stippling and webbing on leaves. Increase humidity and use neem oil to manage infestations.
- Slugs and Snails: These can damage young plants. Use barriers like crushed eggshells or copper tape and remove them manually during wet conditions.
Preventing and Treating Diseases
Diseases are rare but can occur particularly in humid conditions:
- Powdery Mildew: A fungal disease that creates a white powdery coating on leaves. Prevent by ensuring good air circulation and avoiding overhead watering. Treat with a baking soda spray or commercial fungicide if necessary.
- Root Rot: Caused by waterlogged soil. Make there is proper drainage and avoid overwatering to prevent this issue.
Harvesting and Using Mignonette
Harvesting Flowers
For the best fragrance harvest mignonette flowers in the morning. Use sharp scissors to cut stems just as the flowers begin to open.
Uses
Mignonette flowers can be used in:
- Potpourri: Dry the flowers to add a sweet scent to your home.
- Bouquets: Their subtle beauty and fragrance complement other flowers well.
- Perfume making: Historically used in perfumery for its delightful aroma.
Tips for Success
Companion Planting
Mignonette pairs well with other fragrant plants like lavender and roses. It also attracts beneficial insects making it a good neighbor for vegetables.
The Benefits of Companion Planting
Companion planting involves growing different plants together for mutual benefits. Here’s why mignonette benefits from companions:
- Pest Control: Some plants can repel pests that might otherwise harm mignonette. For example marigolds are known to deter aphids and nematodes.
- Attracting Beneficial Insects: Mignonette attracts pollinators which can benefit nearby plants. Pairing with plants like lavender and rosemary can create a haven for bees and butterflies.
- Soil Health: Different plants have varying nutrient needs and root structures helping to maintain balanced soil health. Legumes, like peas and beans, fix nitrogen in the soil, benefiting nitrogen-loving plants like mignonette.
Dealing with Climate
In hotter climates provide afternoon shade to prevent wilting. In cooler regions mulch around the base to protect the roots from freezing.
Extending the Blooming Season
To enjoy mignonette’s fragrance for longer stagger your planting times. Sow seeds every few weeks for continuous blooms.
Staggered Planting
To enjoy continuous blooms throughout the season:
- Sow seeds in batches spacing planting times two weeks apart.
- Choose both early and late-blooming varieties if available.
Seasonal Care Adjustments
Adapt your care routine to the season to maximize blooms:
- Spring: Start with fertilization and regular watering to support new growth.
- Summer: Maintain consistent watering and deadheading. Provide afternoon shade if temperatures soar.
- Fall: Continue deadheading and reduce watering as temperatures cool. Apply a final round of fertilizer if needed.
Common Questions
Why Aren’t My Seeds Germinating?
Mignonette seeds need light to germinate so don’t cover them too deeply. Ensure the soil remains moist but not waterlogged.
Can Mignonette Grow in Containers?
Yes! Choose a pot at least 12 inches deep with good drainage. Container-grown mignonette needs more frequent watering and feeding.
