Choosing the variety of aquilegia
Examples of varieties grown in France
Aquilegia offers a wide variety of cultivars adapted to French gardens. Among the most popular are... Aquilegia vulgaris 'Nora Barlow', renowned for its two-tone double flowers, and Aquilegia caerulea, which displays delicate blue hues. Recent hybrids such as 'Origami Mix' or 'McKana HybridsThey are distinguished by their prolonged flowering period and increased disease resistance. Choosing a variety will depend on the desired style, height, and flower color. Some varieties reach 80-90 cm, while others remain compact, around 40-50 cm.
Selection criteria
To select the right one columbineSeveral criteria must be considered. Mature size, flower color, and shape influence the visual impact in the garden. Hardiness and resistance to diseases or pests are also important. Robust varieties are preferable for humid climates, while evergreen hybrids are better suited to ornamental gardens. Finally, the choice must be adapted to the available space and light conditions.
Differences between hybrids and traditional varieties
Traditional aquilegia varieties, often grown from natural seedlings, have stable growth and classic seasonal flowering. Hybrids, on the other hand, are the result of crossbreeding aimed at producing larger flowers, more unusual colors, and greater disease resistance. While hybrids may require a little more care, they offer a more dramatic display and extend the flowering period. The choice between traditional and hybrid varieties will depend on your priorities: ease of care or enhanced aesthetics.
Where to plant aquilegia
Ideal location in the garden
Aquilegia prefers a location in partial shade to full sun, depending on the intensity of the sunlight. In warmer climates, it's advisable to choose filtered light or partial shade to prevent the flowers from drying out. Sheltered areas are ideal, as the stems can break easily. It can also be planted at the edge of a flower bed, in light woodland, or near hedges, where it adds color and vertical interest without suffering from climatic stress.
Light and shade conditions
For optimal growth, aquilegia needs 4 to 6 hours of sunlight per day. Too much shade slows flowering and encourages fungal diseases on the foliage. Conversely, too much sun, especially in the afternoon, can cause the leaves to dry out and shorten the flowering period. It is therefore recommended to choose the location according to the orientation and amount of sunlight your garden receives, taking the season into account.
Associations with other plants
Aquilegia pairs well with perennials such as hostas, hardy geraniums, or astilbes, which also appreciate light shade. It can also be combined with plants that have complementary blooms to create contrasts in color and height. Planting it near shorter plants highlights its tubular flowers and ensures a harmonious visual effect in the flower bed.
Soil preparation for aquilegia
Recommended soil type
The dove prefers light, fertile, and well-drained soil. Heavy clay soils should be amended to improve aeration and prevent waterlogging, which can cause root rot. Slightly acidic to neutral soil, with a pH between 6 and 7, promotes optimal growth and abundant flowering.
Amendments and fertilization before planting
Before planting, it is advisable to incorporate mature compost or potting soil at a rate of 2-3 kg/m² to enrich the soil with organic matter. A balanced fertilizer, such as a 10-10-10 mix, can be applied during preparation to stimulate initial root development. Amendments should be thoroughly mixed into the existing soil to ensure homogeneity and facilitate root establishment.
Soil drainage and preparation
Good drainage is essential to prevent waterlogging, especially in rainy areas. For heavy soils, it is recommended to create mounds or add coarse sand to the bottom of the planting holes. Soil preparation should also include thorough weeding to limit competition with the aquilegia from the time of planting.
Sowing, planting and propagating aquilegia (colombine) by cuttings
Indoor and outdoor sowing techniques
Aquilegia seeds can be sown indoors from February to March or outdoors in the autumn. For indoor sowing, use small pots filled with light potting soil and keep the soil moist, placing the seedlings in a bright location but out of direct sunlight. Outdoor sowing requires well-prepared soil and a partially shaded location; the seeds should be lightly covered with soil and watered regularly until germination.
Planting methods for young plants
Seedlings or nursery plants should be transplanted after 4-6 weeks, once their roots are well-developed. Dig holes approximately 15-20 cm deep and space the plants 30-40 cm apart to allow for good air circulation. Water thoroughly after planting and protect the young plants from strong winds and intense heat for the first few weeks.
Cuttings and vegetative propagation
Aquilegia cuttings are primarily propagated in spring using semi-hardwood stems. Take 7-10 cm sections, remove the lower leaves, and place them in a light mixture of sand and potting soil. Keep the substrate moist and in a semi-shaded environment until roots develop, which usually takes 4 to 6 weeks. This method allows you to faithfully reproduce the characteristics of the chosen variety.
Aquilegia care
Watering and humidity
Dove-like plants require regular watering, especially during dry periods, to keep the soil slightly moist. Avoid overwatering, which encourages fungal diseases and root rot. Watering should be directed at the base of the plants to protect the foliage and minimize the appearance of spots.
Pruning and thinning
It is advisable to remove faded flowers as soon as they wither to prolong blooming and encourage new flower production. Weak or poorly positioned stems can be thinned to improve air circulation and reduce the risk of disease. At the end of the season, a light pruning of dry stems prepares the plant for winter.
Mulching and protection against the cold
A 5-7 cm layer of organic mulch around the base of the plants helps retain moisture, suppress weeds, and protect the roots from frost. Mulches such as straw, dead leaves, or compost are particularly suitable. In regions with harsh winters, a thicker layer of mulch or a winter fleece effectively protects young plants and their roots.
Prevention and treatment of aquilegia diseases
Most common diseases
Dovecote is susceptible to several fungal and bacterial diseases, including rust, powdery mildew, and root rot. Rust appears as orange spots on the foliage, while powdery mildew is a white, powdery coating. Root rot typically occurs in poorly drained soil and causes the plants to wilt rapidly.
Natural prevention and cultural measures
To limit disease, it is essential to plant aquilegia in well-drained soil and to allow sufficient spacing between plants to promote air circulation. Watering should be targeted at the base of the plant, avoiding wetting the foliage. Regularly remove diseased leaves and practice crop rotation to reduce the presence of pathogens in the soil.
Possible curative treatments
In case of infestation, appropriate fungicide treatments can be applied according to the manufacturer's recommendations. Biological solutions based on copper or sulfur are effective against certain diseases such as rust or powdery mildew. It is important to act quickly as soon as the first symptoms appear to limit the spread and preserve the health of the plants.
Pest control of aquilegia
Common Insects and Parasites
Aquilegia can be attacked by aphids, slugs, snails, and certain caterpillars. Aphids typically focus on young shoots and flower buds, causing deformation and weakening of the plants. Slugs and snails attack the tender foliage, creating holes and leaving mucus trails, while some caterpillars can consume almost the entire leaf.
Biological and chemical control methods
To limit infestations, prioritize biological methods such as introducing ladybugs for aphids or using natural barriers for slugs. Chemical treatment should remain a last resort and be chosen specifically for the type of pest, respecting the dosage and application period. It is recommended to regularly check the condition of the plants to intervene quickly and limit damage.
Regular monitoring and maintenance
Regular monitoring helps detect early attacks and prevent their spread. Inspect the foliage, stems, and soil around the plants at least once a week. Manually remove any pests or diseases. bugs visible and damaged parts to maintain the health of the dove and promote lasting flowering.
Harvesting and storing aquilegia
Harvesting time and method
Aquilegia is harvested when the flowers are fully open but still firm, usually at the beginning of the flowering period. For seeds, wait until the capsules dry and turn brown on the plant before picking them. Use clean scissors or pruning shears to cut the flowers or capsules, being careful not to damage the stems or the plant.
Storage and preservation of flowers and seeds
Cut flowers last best in a vase of fresh water, away from direct sunlight. Seeds should be air-dried for a few days and then stored in paper bags or airtight containers in a cool, dry place. Proper seed storage allows for replanting the following year while preserving the chosen variety.
Techniques to extend the lifespan of flowers
To prolong the life of cut flowers, change the vase water every two days and trim the stems slightly. Avoid exposing the flowers to drafts or excessive heat. Adding a flower preservative or a small amount of sugar to the water can also help keep flowers fresh longer.
Post-harvest care of aquilegia
Cleaning and preparing the soil after harvest
After flowering has finished, it is important to remove faded flowers and dead leaves around the plants to limit the spread of disease. The soil can be lightly loosened and enriched with compost or mature potting soil to prepare the area for the following season. Thorough weeding also reduces competition for nutrients and water.
Pruning plants after flowering
Lightly pruning the stems a few centimeters above the ground encourages regeneration and maintains a neat appearance. Removing weak or damaged stems allows the plant to focus its energy on the roots and the formation of new shoots. This step is essential for the columbine to regain its vigor the following spring.
Preparation for the next season
To ensure optimal establishment, apply a light mulch around the roots to protect them during the winter. Check the overall condition of the plants and replace any that are weak or dead. This post-harvest preparation guarantees that the aquilegia will begin the new season in ideal conditions, with fertile, well-drained soil.
