- Floors: Fits a wide variety of soils (sandy, clayey, calcareous, poor or rich in organic matter). Requires excellent drainage, as it is sensitive to waterlogging; it even thrives in cracks in dry stone walls or spaces between rocks.
- Irrigation: Drought resistant Once established, it appreciates regular watering during very dry periods, always avoiding excess moisture. In pots, it is essential to use loose, well-draining soil to prevent root deterioration.
Planting, multiplication and propagation
The wild daisy is very grateful and easy to multiply, even self-seeding easily in the garden.
- Recommended planting season: Autumn (taking advantage of natural rainfall to promote rooting), although it can also be planted in spring with additional irrigation care during its first summer.
- Planting density: The usual thing is to place 5 to 10 plants per square meter for fast, even coverage in 8-12 months.
- Multiplication systems:
- Division of bush: Ideal for late summer, fall, or early spring. Carefully separate the rooted clumps, ensuring each portion contains sufficient roots and shoots.
- Cuttings: Take stem segments with leaves in late winter or early autumn and plant them in moist, light substrate until they take root.
- Seeds: Direct sow in spring, after the risk of frost has passed. You can also sow in a seedbed and transplant to the garden when the seedlings are well developed.
- Self-seeding: Branches in contact with the ground tend to naturally form new plants, facilitating expansion in the garden.
- Useful tip: Placing pine bark on the substrate can improve the rooting of cuttings and divisions.
Management, pruning and growth control
The vigor of erected karvinskianus It is such that, under optimal conditions, it can colonize large areas and behave as an invasive species. Therefore, responsible management is essential to enjoy its ornamental value without compromising other species in the garden.

- Heavy pruning: At the end of winter or early spring, perform a more drastic pruning to control size and vigor, renewing the plant and preventing the invasion of unwanted areas. This technique also promotes denser, healthier foliage.
- Selective start: If the expansion is excessive, removing some branches can limit its growth.
- Potting Tip: Choose deep, wide containers with light substrate, and control growth by pruning.
Fertilization, maintenance and plant health
Margarita Margarita It is a low-maintenance plant, but if you want to maximize flowering and vigor, it is advisable to follow some tips:
- Subscriber: Add compost or mature manure in late winter or fall to replenish the nutrients depleted by profuse flowering.
- Mineral fertilizer: During flowering, a balanced fertilizer every 15 days can be beneficial, especially in very poor soils.
- Plagues and diseases: Es highly resistant common pests and diseases. It's only necessary to occasionally monitor for the appearance of slugs or snails, especially in humid environments or in dense shade.
