What is the planting depth of freesia
Today, the editor will elaborate on the planting depth of freesia and share some small knowledge about freesia planting and maintenance methods. Let's follow the editor to take a look!
Freesia, also known as small iris or sweet narcissus, has bright flowers and strong fragrance, often planted on balconies, filling the room with fragrance when blooming. Freesia is native to South Africa and belongs to the bulbous flowering plants. It prefers a warm and well-lit environment and is not cold-resistant. The most common problem in the maintenance of freesia is etiolation, and the plant is prone to falling over. How to grow a pot of freesia well is a concern for many freesia lovers. Let's talk about the maintenance of freesia and the issues to be aware of during the maintenance process, hoping it will be helpful to those in need.
Requirements for the growing environment of freesia
1. Soil requirements for planting. Freesia prefers loose and fertile sandy soil, with high requirements for soil drainage. Poor soil drainage can easily cause waterlogging, rotting roots, and bulbs. 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 water permeability, which can effectively prevent 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 be careful not to exceed 5% of the total soil volume;
2. Environmental temperature requirements. Freesia is not heat-resistant nor cold-resistant. High temperatures in summer and low temperatures in winter will cause dormancy. 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, usually needing to be controlled around 15°C;
3. Environmental lighting requirements. Freesia likes sunlight but is afraid of strong light. High light and high temperature can cause etiolation. The formation of freesia flower buds is completed under short-day conditions, and long-day conditions after the formation of flower buds can promote flowering.
Issues to be aware of during the maintenance of freesia
1. Planting should be deep rather than shallow
When planting, the freesia bulbs should be buried deeper in the soil, at least more than 5 centimeters deep. The internodes between the leaves and bulbs of freesia are relatively thin and long. If the bulbs are planted too shallow, the plants are prone to fall over.
2. Watering should be dry rather than wet
Freesia prefers a moist growing environment and a relatively moist soil environment. However, excessive watering during maintenance has two disadvantages. On one hand, excessive soil moisture for a long time can easily cause bulb rot, and on the other hand, excessive watering can cause etiolation of the freesia plant, resulting in thin leaves and the plant falling over. During the growing period, keep the potting soil slightly dry and wet, and water promptly when the surface soil dries. After the flowering period, control the watering moderately, and water the slightly dry potting soil, gradually reducing the amount of watering until summer arrives, when the plant enters dormancy and stops watering;
3. Fertilization should be light rather than concentrated
During the growing period, at least one application of a multi-element compound fertilizer should be used every month. After autumn germination, when the environmental temperature drops to 15°C, two applications of high-phosphorus and potassium compound fertilizer should be supplemented each month until the flowering period. Reduce the application of nitrogen fertilizer during this period, and after the flowering period, increase the application of nitrogen fertilizer to promote rapid plant growth. During the growing period, avoid applying concentrated fertilizer and follow the principle of "frequent application of light fertilizer."
4. Diseases should be prevented rather than treated
The common disease of freesia is mosaic virus, which is difficult to cure once it occurs. Prevention is the main approach. After planting, you can use carbendazim solution to water the roots once a month. Carbendazim is an internal absorbent fungicide that can effectively prevent the occurrence of various diseases. Keeping a good ventilation environment in the maintenance area can also effectively prevent the occurrence of various diseases.
Summary: Freesia is a very easy-to-grow flowering plant. Light has a significant impact on the plant during maintenance. Sufficient light can effectively prevent etiolation and promote bud differentiation. However, excessive light, combined with sufficient water supply, can easily cause etiolation. Therefore, the coordination of water and light during the maintenance of freesia is very important.
