The plant requires ample space to grow properly, and the spacing between individual plants should be between 15 to 40 cm. The spacing depends on the desired size of the plants and the growth pattern of each individual plant.
Watering Needs
Elytropappus glandulosus Less. var. longifolius DC. requires moderate watering during the growing season, and the soil should be kept moist but not waterlogged. Inadequate watering can cause the plant to wilt and dry out, while excessive watering can lead to root rot and other fungal diseases. It is recommended to water the plant early in the morning or late in the evening to reduce water loss due to evaporation.
Fertilization
The plant requires regular fertilization to promote healthy growth and maximum flower production. It is recommended to use a balanced fertilizer with an N-P-K ratio of 10-10-10 or 20-20-20 during the growing season. The fertilizer should be applied every four to six weeks, depending on the soil quality and growth rate of the plant. The fertilizer should be applied to the soil, not the leaves, to avoid burning of the foliage.
Pruning
Elytropappus glandulosus Less. var. longifolius DC. requires pruning to promote bushy growth and prevent the plant from becoming leggy.

Pruning should be done with sharp and clean tools to avoid damaging the plant.
Propagation of Elytropappus glandulosus Less. var. longifolius DC.
Elytropappus glandulosus Less. var. longifolius DC. can be propagated by seeds, stem cuttings, and division.
Seed Propagation
Seeds of Elytropappus glandulosus Less. var. longifolius DC. can be sown directly in the ground in the fall. The seeds need a period of cold stratification before they can germinate, so the best time to sow them is in mid-to-late fall. The seeds should be sown in well-drained soil that is rich in organic matter and placed in a sunny location. The seeds will germinate in the spring.
Stem Cutting Propagation
Elytropappus glandulosus Less. var. longifolius DC. can be propagated by stem cuttings. Take 4-6 inch cuttings in the spring, just before the plant begins to grow. Use a sharp, clean pair of scissors or pruning shears and make sure the cuttings are taken from healthy plants. Cut just below a node and remove the lower leaves. Dip the cut end of the stem in rooting hormone and plant the cutting in well-drained soil that is rich in organic matter. Water the cutting regularly and keep it in a sunny location. The cutting should root within a few weeks.
Division Propagation
The root ball of a mature Elytropappus glandulosus Less. var. longifolius DC. plant can be divided into smaller sections in the early spring, just before new growth begins. Use a sharp, clean pair of scissors or a knife to carefully separate the root ball into 2-3 sections. Each section should have some roots and some foliage attached. Replant the sections in well-drained soil that is rich in organic matter and water them regularly. Keep the plants in a sunny location and they should begin to grow within a few weeks.
