Watering Needs
As mentioned, Hedysarum granulatum Schumach. & Thonn. does not require frequent watering. The plant is well-adapted to dry conditions, and too much water can be detrimental to its growth. The plant only needs watering when the topsoil is dry to the touch. When watering the plant, it is recommended to water deeply but not to overwater.
Fertilization
The plant does not require excessive fertilization. However, applying a balanced fertilizer during the growing season can help enhance its growth and improve its overall health. Fertilizer should be applied sparingly, following the manufacturer's instructions carefully to avoid causing any damage to the plant.
Pruning

Cut back any dead or damaged branches, shaping the plant as desired.
Propagation methods for Hedysarum granulatum Schumach. & Thonn.
Hedysarum granulatum Schumach. & Thonn. can be propagated from both seeds and cuttings.
Propagation from seeds
The plant seeds can be easily collected from the dry pods during the fall season. The collected seeds must be dried and stored before sowing in the spring season.
The germination of the seeds is very slow and requires a lot of patience. The seeds must be soaked in warm water for several hours before sowing to induce germination.
The germinated seeds can be sown in trays or pots filled with potting mix. The pots should be kept in a well-lit area, and regular watering should be done to keep the soil moist.
Propagation from cuttings
The plant can also be propagated from semi-hardwood cuttings taken during the late summer season. The cuttings should be around 10-15 cm long, with a few leaves attached to them.
The cuttings must be dipped in rooting hormones and planted in pots filled with a mixture of sand and peat. The pots must be watered regularly, and to promote the growth of roots, the cuttings should be placed under high humidity and bright light.
The cuttings can be transplanted to larger pots or directly to the soil after the roots are well established in the pot.
Disease and Pest Management for Hedysarum granulatum Schumach. & Thonn.
Hedysarum granulatum Schumach. & Thonn. is generally a sturdy and disease-resistant plant. However, there are a few diseases and pests that may typically affect it. It is always better to prevent these problems before they occur, but there are also ways to manage these diseases and pests if they have already affected the plant.
Common Diseases
1. Root Rot: Root rot is one of the primary diseases that impact Hedysarum granulatum Schumach. & Thonn. This disease is caused by soil-borne pathogens, mainly fungi, that attack the roots of the plant. To avoid this problem, avoid water-logging around the plant's roots. If root rot has already affected the plant, remove the infected parts and repot the plant in fresh potting mix.
2. Powdery Mildew: Another common disease that affects Hedysarum granulatum Schumach. & Thonn. is powdery mildew. It usually appears as a white or grey powdery substance on the plant's leaves and stems. To prevent this issue, maintain good air circulation around the plant and avoid overcrowding. If the plant has already been infected with powdery mildew, remove the infected parts and treat the plant with a fungicide.
Common Pests
1. Aphids: Aphids are the most common pests that might affect Hedysarum granulatum Schumach. & Thonn. These small, soft-bodied insects feed on the plant's juices, causing the foliage to develop yellow spots and become deformed. To avoid this issue, use an insecticidal soap spray or neem oil to kill the aphids. Always inspect the plant regularly and remove the infected parts immediately.
2. Spider Mites: Spider mites are another common pest that can cause problems for Hedysarum granulatum Schumach. & Thonn. These pests are tiny and difficult to detect until the plant has already been severely affected. They suck the sap from the leaves and damage the foliage. To prevent this issue, regularly spray the plant with water to create adequate humidity levels and use a miticide to kill the mites.
In conclusion, it is always better to prevent diseases and pests before they affect the plant. Therefore, proper care and maintenance can go a long way in ensuring the health of the plant. However, if the plant is already infected with a disease or pest, the above-mentioned methods can be an effective way to manage them.
