The seeds can be planted in a well-draining potting mix, that is moist but not waterlogged. To speed up the germination process, growers can soak the seeds in water for 24 hours before planting. The seeds should be planted no more than ¼ inch deep in the soil. The container should be covered with a plastic bag or a plastic wrap to maintain moisture levels. The container should then be placed in an area that receives ample sunlight for optimal growth. The seeds can take up to two weeks to germinate.
Propagation by Cuttings
Hymenoclea salsola Torr. & Gray ex Gray var. pentalepis (Rydb.) L. Benson can also be propagated through stem cuttings. The best time for taking cuttings is during the spring season when new growth appears. The cuttings should be taken from healthy and mature plants.
The cuttings for Hymenoclea salsola Torr. & Gray ex Gray var. pentalepis (Rydb.) L. Benson should be around 4-6 inches long, and the leaves should be removed from the lower 2 inches of the stem. The cuttings should then be dipped in rooting hormone before planting in a soilless medium or well-draining potting mix. The container should be covered with a clear plastic bag or plastic wrap to maintain humidity levels. The cuttings should be placed in an area that receives ample sunlight but not direct sunlight for optimal growth. The cuttings can root in about two to three weeks.

Diseases:
Fungal Leaf Spots: Fungal leaf spots are common in Hymenoclea salsola Torr. & Gray ex Gray var. pentalepis (Rydb.) L. Benson and can occur when the plant is stressed. The spots are usually circular, and the affected leaves may turn yellow and fall off. To manage this disease, remove any dead leaves from the plant and avoid overhead watering. Apply fungicide if necessary.
Root Rot: Root rot is caused by a fungus that attacks the plant's roots, preventing it from absorbing water and nutrients. This disease can occur when the plant is overwatered or planted in poorly-drained soil. To avoid root rot, plant the Hymenoclea salsola Torr. & Gray ex Gray var. pentalepis (Rydb.) L. Benson in well-drained soil and avoid overwatering. Remove any infected plants as soon as possible to prevent the spread of the disease.
Pests:
Aphids: Aphids are small, pear-shaped insects that feed on the sap of the plant. They can cause stunted growth and yellowing of the leaves. To manage aphids, spray the plant with a stream of water to knock them off. If the infestation is severe, apply insecticidal soap or neem oil.
Spider Mites: Spider mites are tiny pests that can cause discoloration and wilting of the leaves. They are often found on the undersides of leaves. To manage spider mites, spray the plant with a stream of water to knock them off. You can also apply insecticidal soap or neem oil.
