Seed propagation
The most common method of propagating Eryngium prostratum Nutt. ex DC. var. disjunctum Fern. is through seed propagation, which is easy and reliable. Seeds can be sown directly into the soil in the fall or early spring. They require a period of cold stratification to break dormancy, so it is recommended to sow them in the fall so they can receive the necessary chilling hours during the winter. When planting, the seeds should be sown at a depth of around 1/8 inch and spaced about 6 inches apart.
Division
Eryngium prostratum Nutt. ex DC. var. disjunctum Fern. can also be propagated through division. This method should be done in the early spring or fall. Carefully dig up the plant and separate the roots and leaves into several clumps. Each clump can be replanted in a new location and should be watered immediately after planting.
Stem cuttings
Propagation through stem cuttings is also possible with Eryngium prostratum Nutt. ex DC. var. disjunctum Fern. Cuttings should be taken in the summer, when the plant is actively growing. Select healthy stems and snip them off just below a leaf node. Remove the leaves from the bottom half of the stem and dip the cut end in rooting hormone. Place the stem cutting in a pot filled with sterile potting mix and water regularly. The cutting should root in a few weeks and can then be transplanted to a larger pot or directly into the garden.

2. Powdery Mildew: Powdery mildew is a fungal disease that's characterized by white or grayish powdery growth on the leaves of the plant. The symptoms include distorted or curled leaves, and stunted growth. To avoid powdery mildew, make sure the plant has good air circulation, is not overcrowded, and is not overfertilized. If powdery mildew has already affected your plant, use a fungicide to treat it.
Common Pests
1. Spider Mites: Spider mites are tiny pests that suck the sap out of plants, causing them to turn yellow and become weak. The symptoms include tiny webs on the plants, yellowing leaves, and stunted growth. To avoid these pests, keep the plants well-hydrated and remove any dried leaves or debris. If spider mites have already affected your plant, use an insecticidal soap to treat it.
2. Aphids: Aphids are small, pear-shaped insects that suck plant sap. They can be green, black, brown, yellow, or pink. The symptoms of aphid infestation include curled or yellowed leaves, stunted growth, and the presence of ants on the plant. To avoid aphids, keep the plants well-fertilized and remove any weeds or debris. If aphids have already affected your plant, use insecticidal soap or neem oil to treat it.
