What is the reason why freesia does not bloom? How to care for freesia

No matter how beautiful the freesia is, it is still a plant. Just like a small sapling, it needs to be maintained, pruned, watered, fertilized, etc., and carefully cared for. For it, if the plant grows too high, it will not only consume a lot of nutrients, but also affect the appearance. Let's take a closer look at the maintenance and pruning of freesia!

How to care for freesia

1. Soil: Freesia prefers sandy loam that is rich in organic matter, has strong water retention and good drainage, with a pH of 6 to 7.2.

2. Watering: The soil must be kept moist before budding. After budding, the amount of watering should be gradually reduced and the soil surface should be kept dry as much as possible to reduce air humidity and prevent diseases.

3. Light: Although freesia likes light, it should also be avoided from strong light. When the light is too strong or the temperature is high, you can use a shade net with a light transmittance of 70% to provide shade.

4. Temperature: Temperature management is very important for freesia cut flower production. It has poor cold resistance and the suitable growth temperature is 15-20℃, and the minimum temperature for wintering is 3-5℃.

5. Fertilization: Organic fertilizer and compound fertilizer applied before planting can basically meet the growth needs, but if the plant growth is weak, apply ammonium nitrate, urea and potassium sulfate again when it has 2 to 4 leaves. Use 0.2% potassium dihydrogen phosphate as foliar fertilizer when it first blooms, but it is best to avoid topdressing before and after budding.

6. Pests and diseases: Freesia is prone to mosaic disease, bulb rot, etc. The soil and bulbs should be thoroughly disinfected when planting, and the potting soil should be completely replaced every year. At the same time, pay attention to the prevention and control of aphids. In the early stage of aphids, spray 40% omethoate 1500 times liquid or 90% trichlorfon liquid for prevention and control.

How to prune freesia

1. Prune long branches

For it, if the plant grows too high, it will not only consume a lot of nutrients, but also affect the appearance. Pruning time is not restricted and can be done in four seasons of the year. Cutting off part of the overlong branches on the plant can effectively promote the formation of side buds and play a role in promoting the lushness of the plant.

2. Timely pinching

During the vigorous growth period of the plant, the branches will grow in disorder, various branches will begin to grow wildly, and the main trunk will be very high. At this time, it is necessary to top it and remove the top growth point to inhibit the growth of the main trunk and allow the branches and buds next to it to grow. When the branches that appear later also become longer, they must also be processed.

3. Cut off dead branches

During the growth process, due to the influence of normal metabolism, some dead branches and yellow branches will appear. These must be cut off immediately after they appear. There is no specific time, and they should not be left on them to infect other branches and leaves.

4. Pruning after flowering

Its flowering period is from February to May and lasts for about 15 days. When the flowers fade and wither, in addition to removing the remaining flowers, the withered stems should also be cut off and the bulbs should be taken out and stored.

What is the reason why freesia does not bloom?

1. Insufficient light. Freesia has a great demand for light before flowering. Sufficient light is needed to ensure the normal flowering of freesia. If there is insufficient light before flowering, it will have a great impact on the differentiation of flower buds of freesia, thus delaying the flowering period of freesia.

2. The temperature is too low. Along with light factors, temperature is also a major reason why freesia does not bloom. As I just said, the flowering period of freesia is in summer, so it also has certain requirements for temperature. If the temperature is too low, freesia will grow slowly, easily freeze or enter a dormant period, affecting its flowering.

3. Excessive watering. Although freesia has a great demand for water during its growth, we must also pay attention to controlling the amount of watering and the frequency of watering. However, excessive watering and excessive growth of freesia in a humid environment for a long time are not allowed, otherwise it will easily lead to root rot, which is also very detrimental to the growth of freesia.

4. Insufficient nutrition. When the freesia blooms, it consumes a lot of nutrients, so fertilization is very important. If fertilization is not done in time, resulting in insufficient nutrients, the freesia will delay flowering due to lack of nutrition and will not bloom.

What is the cultivation method of freesia

1. Potting soil selection: Freesia has high requirements for soil. It grows best in sandy soil with strong drainage, looseness, fertility and rich humus. When potting, you can choose a mixture of leaf mold, garden soil, fine sand and decomposed organic fertilizer. Use a drug to disinfect it once before planting. It is best to use a shallow pot when planting, because the roots of freesia are bulbs, which are different from other flowers and plants. Too deep a pot is not conducive to management, while a shallow pot can ensure that it has enough growth space.

2. Light and temperature environment: Freesia has relatively high requirements for temperature. Growing in a suitable temperature is the basis for its flowering. The optimum temperature for growth is 10-20 degrees. At night, it is between 10-15 degrees. Maintaining a suitable temperature difference is extremely beneficial to its growth. In winter, the temperature should be avoided below 3 degrees. Freesia is a light-loving plant, so it should be kept in sufficient light during the seedling stage, growth period and flowering period. However, it must be avoided from strong sunlight exposure in March and April, because the temperature will be too high if it is placed in the sun. Once it exceeds 25 degrees, it will cause its growth to slow down. Therefore, it is very unfavorable for growth when the light is too strong.

3. Watering and fertilizing: When potting freesia, you can add some base fertilizer to the bottom of the pot. Do not fertilize too much in the seedling stage. You can apply topdressing once a month during the vigorous growth period. It is recommended to apply decomposed bean cake fertilizer. You can also spray potassium dihydrogen phosphate during the flowering period, which can promote the germination of flower buds and make the flowers more colorful. How to water freesia is a science. Generally, you can water it once a week for daily maintenance. If the soil dries out quickly, you should shorten the watering time. In the vigorous growth period, you need to water it every 3-5 days.

Can the leaves of freesia be trimmed?

Freesia can be pruned. If the leaves grow too long, they must be pruned in time, otherwise it will consume nutrients and affect flowering, and may also cause the plant to fall over. Freesia is a perennial bulbous herbaceous flower of the genus Freesia, Liliales, Iridaceae, and Freesia. The bulb is narrowly ovate or ovate, the leaves are sword-shaped or strip-shaped, the flower stems are upright, the flowers are upright and sessile, light yellow or yellow-green, and have a fragrance.
