How to Plant and Care for Freesia Bulbs
The editor introduces how to plant and care for freesia bulbs and the cultivation methods of green plants and flowers. Let's learn about it together next.
Freesia is also known as small iris or sweet narcissus, with bright flower colors and a strong fragrance. It is often planted on balconies, filling the room with fragrance when blooming. Freesia is native to South Africa and belongs to bulbous flowering plants, preferring a warm and well-lit environment and being intolerant to cold. The most common problem in the maintenance of freesia is etiolation, where the plant easily falls over. How to grow a pot of healthy freesia is a concern for many freesia enthusiasts. Let's talk about the care of freesia and the issues to be aware of during the maintenance process, hoping it will be helpful for those in need.
Requirements for the Growth Environment of Freesia
1. Soil requirements for planting. Freesia prefers loose and fertile sandy soil, with high demands on soil drainage. Poor drainage can cause waterlogging, leading to root and bulb rot. The soil can be mixed with three parts of decomposed leaf soil and two parts of coarse river sand. Decomposed leaf soil is loose and fertile, rich in nutrients, and river sand has good drainage, effectively preventing waterlogging in the pot. When planting freesia bulbs, it is best to add a moderate amount of base fertilizer to the soil, such as organic fertilizer or slow-release compound fertilizer, but the amount should not exceed 5% of the total soil volume;
2. Environmental temperature requirements. Freesia is intolerant to high temperatures and cold, and will enter dormancy in both summer heat and winter cold. The most suitable growth temperature is between 15°C and 25°C. High light and humidity can cause etiolation (this point is very important), and high temperature during the flowering period can shorten the flowering period, generally needing to be controlled around 15°C;
3. Environmental lighting requirements. Freesia enjoys sunlight but is afraid of strong light. High light and high humidity can cause etiolation. The formation of freesia flower buds occurs under short-day conditions, and long-daylight after bud formation promotes flowering.
Issues to be Aware of During the Maintenance of Freesia
1. Planting Deep Rather Than Shallow
When planting, the bulbs should be buried deeper into the soil, at least more than 5 centimeters deep. The internodes between the leaves and bulbs of freesia are relatively long, and if the bulbs are planted too shallowly, the plants may easily fall over.
2. Watering Dry Rather Than Wet
Freesia prefers a moist growing environment and soil, but excessive watering can be detrimental in two ways: first, prolonged high soil moisture can cause bulb rot, and second, excessive watering can lead to etiolation, with long and thin leaves and the plant falling over. During the growing period, maintain the soil to be slightly dry on the surface and water promptly after it dries. After flowering, moderate watering should be controlled, slightly drying the potting soil before watering, and then gradually reducing the amount of water until summer arrives when the plants enter dormancy and watering stops;
3. Fertilizing Light Rather Than Heavy
During the growing period, at least one application of a multi-element compound fertilizer should be used each month. After autumn germination and before the environmental temperature drops to 15°C, two applications of high-phosphorus and potassium compound fertilizer should be supplemented each month until flowering. Reduce the application of nitrogen fertilizer during this period, and after flowering, increase the application of nitrogen fertilizer to promote rapid plant growth. Avoid applying heavy fertilizers during the growing period and follow the principle of "frequent light fertilization."
4. Disease Prevention Rather Than Treatment
The common disease of freesia is mosaic virus, which is difficult to cure once it occurs. Prevention is the main approach. After planting, a fungicide solution of carbendazim can be used to water the roots once a month. Carbendazim is an internal absorbent fungicide that can effectively prevent the occurrence of various diseases. Also, maintaining good ventilation in the maintenance environment can also effectively prevent the occurrence of various diseases.
Conclusion: Freesia is a very easy-to-grow flowering plant. Light has a significant impact on its plant growth, and sufficient light can effectively prevent etiolation and promote bud differentiation. However, excessive light combined with ample water supply can easily cause etiolation, so the combination of water and light during the maintenance of freesia is very important.
