In what season are osmanthus seedlings planted?

Early spring or late autumn is suitable for planting osmanthus trees.

Matters needing attention in osmanthus planting:

How to apply fertilizer after the spring? Fertilization should be started when the temperature rises above 15℃ at night. At this time, branches begin to grow and need fertilization. Drill four small holes around the pot soil, evenly put down the compound fertilizer, and then cover it with soil. Stop fertilizing as soon as the buds grow out. Overnutrition will cause buds to fall off (except Sijigui). Spraying flowers and makeup can make buds strong, petals plump, colorful and fragrant.

The principle of ventilation is that natural air circulation can increase the air humidity around potted flowers, increase the content of carbon dioxide around leaves, and recycle the air around leaves with germs, which is the same as "running water does not rot", making potted flowers not easy to get sick.

How to prune before the temperature rises above 15℃ in spring, and use household scissors or sharp blades to cut off dead branches, twigs and branches with pests and diseases, so as to make way for new branches and not give opportunities for pests and diseases to propagate (pay attention to coating anti-corrosion film on the pruning mouth to promote wound healing).

Pest control If pests are found, household spray insecticides can be used; When diseases are found, the diseased leaves or branches are directly cut off.
