How to Grow and Care for Your Leucanthemum ‘Ooh La Lagrande’

Soil – Prefers well-drained, fertile soil that is rich in organic matter. It can tolerate a variety of soil types as long as drainage is good.
Light – Grows best in full sun, where it can receive at least 6 hours of direct sunlight each day. It can tolerate light shade, but blooming may be reduced.
Watering – Water regularly, particularly during dry spells, but be sure the soil drains well to prevent waterlogging. Once established, ‘Ooh La Lagrande’ is moderately drought-tolerant.

Maintenance:

Mulch & Feed – Apply a layer of mulch around the plant in spring to retain moisture, suppress weeds, and regulate soil temperature. Fertilize lightly with a balanced, slow-release fertilizer at the beginning of the growing season to promote healthy growth and an abundant bloom display.
Deadheading & Cleanup – Remove spent flowers regularly to promote continuous blooming and keep the plant looking tidy. After the flowering season, cut back the plant’s stems to keep the garden neat and encourage new growth.
Division – Divide every 2-3 years to prevent overcrowding and to maintain plant vigor. The best time to divide is in early spring or fall, when the plant is not actively blooming.
