Orange Hawkweed is quite drought-tolerant once established, but it thrives best with consistent moisture. Water regularly during prolonged dry spells, especially if planted in containers or newly established. Ensure the soil is well-drained to prevent waterlogging, which can lead to root issues. Overwatering is generally more detrimental than slight underwatering for this resilient plant. Aim for moist, not soggy, conditions.

Pruning Orange Hawkweed primarily involves deadheading spent flowers to prevent seed dispersal, which is crucial for managing its invasive tendencies. Regularly cutting back the flower stalks before they go to seed can significantly reduce its spread. Additionally, you can trim back any aggressive stolons or runners to contain the plant within its desired area. This helps maintain a tidier appearance and prevents it from encroaching on other plants.

Orange Hawkweed propagates very easily and aggressively, primarily through its numerous stolons (runners) that root where they touch the ground, forming new rosettes. It also produces abundant wind-dispersed seeds. For intentional propagation, simply dig up and separate rooted stolons or divisions from the main plant. These can be replanted directly into new locations. Seed collection and sowing are also viable but less controlled methods due to its invasive nature.

Repotting Orange Hawkweed is typically only necessary if it's being grown in a container, which is uncommon due to its aggressive spreading habit. If container-grown, repot every 1-2 years into a slightly larger pot with fresh, well-draining potting mix to accommodate its root growth. This plant can quickly fill a pot, so regular division during repotting can help maintain its vigor and prevent it from becoming root-bound.
