What are the cultivation methods and precautions of freesia

Freesia growth habits

Freesia likes a cool, humid, sunny environment, and is not cold-resistant. The most suitable temperature for its growth is 15~20℃. The lowest temperature in winter is 3~5℃, and freesia is a short-day plant. Short light can promote flower bud differentiation. After flower bud differentiation, appropriately increasing the sunlight can promote early flowering.

Freesia cultivation method

Soil selection: The cultivation soil should be loose, acidic soil containing organic matter and with good drainage. It can be mixed with leaf mold, garden soil, river sand, etc. in a certain proportion.

Temperature management: Only an environment between 15°~20° can ensure its normal growth; in order to promote flower bud differentiation, the temperature can be controlled between 12-15°C. After the flower buds differentiate, the temperature should be controlled between 18-20°C.

Watering method: Watering should follow the principle of watering when the soil is dry and moistening when the plant is wet. When the plant is just transplanted into the pot, it does not require too much water and watering once a week is enough. After the plant has sprouted, you need to increase the amount of watering to keep the soil moist. After the flowering period is over, gradually reduce the water supply.

Fertilization method: Freesia needs more fertilizer, and you can choose phosphorus and potassium fertilizers, and fertilize once every half a month; after budding, you need to apply decomposed organic fertilizer to promote flowering; and during the flowering period, you need to apply a solution containing potassium dihydrogen phosphate, which can make the leaves grow more shiny. Be careful not to pour the fertilizer liquid on the leaves.

Precautions for freesia cultivation

Freesia is easily harmed by mosaic disease and bulb rot. When planting, the soil and bulbs should be thoroughly disinfected, and the potting soil should be completely replaced every year. At the same time, attention should be paid to the prevention and control of aphids. If aphids are found, they can be sprayed with 1500 times diluted 40% omethoate or 90% dichlorvos solution for prevention and control.
