How to grow lobelia

Soil

Lobelia likes moist soil. When choosing the medium, sandy soil is the main choice.

Light and temperature

Lobelia likes a warm and semi-shady growing environment. The suitable temperature for growth is between 25℃-30℃. It is not tolerant to cold and requires overwintering in winter. The temperature is relatively high, and it is better to keep it above 15°C. If it is lower than this value, the growth of the lobelia plant may be stagnant. When the temperature is higher than 30°C in summer, watering is needed to avoid its death. The light should be sufficient, and the light time should be extended to bloom faster. In summer, when the sun is strong, you need to pay attention to shade in time.

Watering and fertilizing

Lobelia likes a humid growing environment and needs to keep the soil moist during the growth period. It needs to be watered in the dry season to ensure sufficient water and watering. Try to choose the time in the morning or early morning. Fertilizing does not need to be too frequent. Just apply some base fertilizer to provide nutrients when planting, and then topdress appropriately. Topdress urea or human and animal manure in summer, and topdress decomposed local fertilizer in winter.

Precautions for breeding lobelia

Propagation methods

The propagation of lobelia includes seed propagation, cutting propagation and division propagation. Division is mainly carried out in spring, and this method is often used in production. Cuttings are carried out during high temperature seasons.

Pests and diseases

Lobelia diseases and insect pests are not common, but there are threats of plant lodging, spots on leaves and other diseases, which need to be prevented and controlled in time.

Notes on flowering

First of all, lobelia blooms easily when the temperature difference between day and night is large and the light is strong, and the light time needs to be appropriately extended; secondly, when too much nitrogen fertilizer is applied, During the period, excess nutrients will reduce flowering; finally, do not fertilize or spray pesticides during the flowering period of lobelia.
