Care Guide

💧 Water

Jersey thrift flourishes in coastal areas, favoring saline and moist sandy soils. It needs consistent moisture and can withstand short periods of drought, making weekly watering ideal. Being an evergreen plant, jersey thrift requires a stable water supply, particularly during the colder months when indoor heating can lower humidity.

☀️ Light Full sun

The sea cushion is a perennial herbaceous plant that loves sunshine and originates from open habitats, often flourishing in meadows and grasslands. It favors full sunlight but can also withstand conditions with only partial sun.

Ideal: Full sun
🌡️ Temperature 5–35°C

The sea cushion plant is capable of acclimating to a broad spectrum of temperature environments, yet its presence may be impeded by varying mixtures of heat and water conditions. It flourishes most effectively in humid climates during summer given sufficient precipitation or irrigation. Extended stretches of overcast and rainy climates, as well as extended high temperatures, can elevate the chances of the sea cushion plant dying. During the colder months, the plant's survival odds can be enhanced with appropriate cold-weather protection.

Ideal temperature: 5–35°C

🌱 Fertilizer

The optimal period to fertilize a Sea cushion is at the start of spring, as it comes out of dormancy and begins to grow actively. Fertilization supplies vital nutrients required for robust growth. While the Sea cushion does not demand extensive fertilization, providing fertilization once a year can improve its longevity and induce superior, more durable flowers.

✂️ Pruning

Jersey thrift benefits greatly from pruning, which should be done from early spring through late winter. To promote new growth and keep the plant healthy, trim away spent blooms, remove leggy stems, and clear out dead foliage. Always sanitize your tools before pruning and do so moderately to encourage denser foliage and better flowering without stressing the plant.
