Care Guide
Watering
Sea holly (Eryngium 'Neptune's Gold') require moderate water. Water the plant only when the soil is dry to the touch, approximately every 1-2 weeks. During the summer months, water more frequently to keep the soil evenly moist but be careful not to over water. Allow the soil to dry out slightly between waterings. If the leaves become wilted, water immediately.
Light
Sea holly (Eryngium 'Neptune's Gold') should receive at least 5 to 6 hours of direct sunlight each day and should be planted in a location with full sun exposure. The plant should be shaded from direct, mid-day summer sun, as this can cause the plant to become too hot and dry out quickly. To ensure the health and flowers of the sea holly, it is important to provide the best possible light environment.
Temperature
Hardiness zone 5-8.
Pruning
Sea Holly (Eryngium 'Neptune's Gold') responds best to a light pruning. Pruning should take place in early spring, meaning as soon as the danger of frost has passed. This ensures that the new growth will be free from damage and will produce the best results. For established plants, prune back the stems that have died back over the winter. This will encourage new growth in the spring. Feel free to also prune a few of the stems to add shape and air flow to the plant. Doing so will help improve the look of the plant and promote healthy growth.
