watering
Water Eryngo (Eryngium alpinum 'Blue Star') deeply and infrequently. To ensure your plant is getting the proper amount of moisture, it is best to let it dry out between waterings. Aim to water the plant whenever the top 2-3 inches of soil feels dry to the touch. In general, the plant should be watered every 7-10 days during the growing season. During the winter months, you may need to water even less frequently.
sunlight
Eryngo (Eryngium alpinum 'Blue Star') prefers full sun (6 to 8 hours of direct sunlight each day) in order to grow optimally. Some shade is tolerable, although the plant may not yield as many blooms in partial shade as it does in full sun. Avoid places that get so much sun that the soil dries out completely. It is best to position the plant so that it receives sun in the morning or the early afternoon, rather than intense afternoon sunlight. Too much afternoon sun can cause the leaves of the eryngo to droop and become scorched.
pruning
Eryngo (Eryngium alpinum 'Blue Star') is not an intense pruning plant and typically does not need to be pruned. However, in order to keep the plant looking neat and to promote branching, it is recommended to remove any dead or damaged stems when noticed. It is best to complete light maintenance pruning in the early spring, just before new growth starts. It is also beneficial to remove any flower stalks after blooming. Any heavy pruning should be avoided.
