watering

It's important to water Sea Holly 'Tiny Jackpot' regularly to ensure the best growth and health of the plant. When watering, it should be done thoroughly and consistently to ensure that the plant is getting enough moisture without becoming waterlogged. Ideally, you should water Sea Holly 'Tiny Jackpot' once a week, allowing the top of the soil to dry out between waterings. As a general rule, it's best to water until you've soaked the soil about an inch deep. When you water, be sure to avoid wetting the foliage. This can lead to fungal diseases and leaf problems. Instead, it's better to water directly at the base of the plant. During the warmer months it's important to monitor the moisture level of the soil more closely. Over-watering can be an issue during hotter months, so check the soil for dryness first before watering. Summer heat can quickly evaporate the water, leaving plants thirsty and in need of a drink.

sunlight

Sea holly prefers full sun to part shade for optimum growth. If growing in full sun, the plant should be given at least 6 hours of direct sunlight a day. If growing in partial shade, the sun should reach it for at least 4 hours of direct sunlight and a few hours of indirect sunlight. For best results, aim for morning sun and afternoon shade for the plant.

pruning

Sea holly should be pruned lightly in the late winter or early spring before new growth begins. Pruning should remove any dead or damaged foliage and encourage fresh, healthy growth. To give the plant a compact shape, shear back the foliage to about 1-third of its total growth. Don't prune too heavily, as this can damage the plant. Additionally, any stems that cross over each other and restrict airflow should be removed. Avoid pruning during the peak of summer, as this can shock the plant and cause damage.
