How do you manage the flower buds when growing a nopal cactus (Epiphyllum)?

  The nopal cactus originated in Mexico and was later gradually introduced to China. Because its shape closely resembles an arrow, people call it the nopal cactus, and since its flowers are not only gorgeously colored but also very beautiful, most flower lovers choose to grow it. However, managing the nopal cactus during its flower bud stage has become the issue that flower lovers care about most. Below, the editor summarizes the management methods for nopal cactus flower buds.

  Management of nopal cactus flower buds

   1. Watering management: During the flower bud period of the nopal cactus, that is, the bud gestation period, the demand for water is relatively high, so the amount of watering should be somewhat more than before. You can choose to alternate between watering and misting. As long as the amount of water keeps the potting soil slightly moist, that is enough. Do not water too much, but do not let the potting soil get too dry either, otherwise the flower buds are prone to withering, so water must be provided in time.

  2. During the growth period of the flower buds, ensure the plant receives normal sunlight, with each day's light exposure kept within five or six hours. The environmental temperature in which the plant grows is also related to air circulation. When the temperature is 15-20 degrees, it is favorable for the nopal cactus flower buds to bloom. If the temperature is relatively high, flower buds that are developing may tend to revert into young shoots. Therefore, the environmental temperature and air circulation must also be controlled to some extent.

  3. During the bud gestation period, the nopal cactus plant grows relatively many new branches, which will compete with the flower buds for nutrients, resulting in insufficient nutrients for the flower buds' growth and causing the buds to wither. Therefore, branches should be removed in time, which also helps air circulation around the plant. Air circulation can expel trapped gases such as ethylene that cause flower buds to age prematurely, thereby protecting the flower buds.

  4. Before the flower buds form, top-dressing should be carried out in time. After the flower buds appear, too much top-dressing should not be applied. Some plants grow very luxuriantly but simply do not bloom, mainly because the placement site is too shady, or because too much fertilizer and water cause excessive vegetative growth. Therefore, fertilizer and water must be applied sparingly, care must be taken to avoid applying excessive nitrogen fertilizer, and sufficient light duration must be ensured. During the bud gestation period, additional phosphorus and potassium fertilizer can be applied, which helps the flower buds form and bloom. In winter, the plant should be moved into a greenhouse to overwinter, maintaining the indoor temperature.

  In summary, for the nopal cactus during the flower bud gestation period, pay attention to sunlight, temperature, top-dressing and air circulation, and carry out basic management. Handled this way, there should be no problems.

How to grow the nopal cactus. Growing methods and precautions for the nopal cactus

Growing the nopal cactus is not very different from that of most plants in the cactus family; it is likewise water, nutrients, sunlight, soil and so on. However, to grow the nopal cactus well, the details of these growing steps become relatively important. Friends who need this should read carefully!

How to grow the nopal cactus

1. Soil requirements for the nopal cactus

The nopal cactus does not have especially high soil requirements; loose, fertile, well-drained sandy loam is sufficient. As long as care is taken during maintenance that the soil does not become compacted, ordinary soil can be used.

2. Watering requirements for the nopal cactus

During the growth and development period of the nopal cactus, watering should follow the principle of watering when dry and letting it dry between waterings. Take care that water does not accumulate in the pot, otherwise root rot is very likely. When flower buds have already appeared but have not yet opened, watering also should not be increased, otherwise flowers and buds will drop.

In the dry and windy spring and summer, frequently spray the stems and leaves with clean water and sprinkle water on the surrounding ground to maintain relatively high air humidity, which is more favorable for growth and flowering.

3. Sunlight requirements for the nopal cactus

The nopal cactus likes a warm and humid environment, but cannot tolerate direct sunlight. When the weather is relatively hot in summer and the sunlight is strong, place the plant under a shade shed to avoid direct sunlight, and frequently sprinkle or spray water on the surrounding ground to increase air humidity. Winter weather is cold. The nopal cactus is not cold-tolerant, so after bringing it indoors, place it in a spot with ample sunlight.

4. Temperature requirements for the nopal cactus

The nopal cactus is not cold-tolerant. In northern regions, it should be brought indoors around the Cold Dew solar term, and after being brought indoors, placed in a spot with ample sunlight. From November to March, keep the maintenance temperature for the nopal cactus between 10~15°C. The temperature must not be too high; above 25°C, the plant is prone to excessive vegetative growth, affecting a well-proportioned plant shape. From March to June, the temperature should be kept between 13~18°C; if the temperature is too low, bud gestation will be affected.

5. Pruning requirements for the nopal cactus

Because the modified stems of the nopal cactus are soft, thin bamboo poles are needed as supports. It is best to tie them into an oval trellis and distribute the modified stems evenly and neatly on the trellis and tie them in place. This not only prevents breakage but also facilitates ventilation and light penetration, making the plant shape well-proportioned and attractive.

6. Fertilizing requirements for the nopal cactus

The nopal cactus likes fertilizer. During the growing season, apply diluted, well-rotted cake fertilizer water once every 15-20 days. After the Spring Festival, change to applying liquid fertilizer once every 10 days, and promptly remove excessive lateral buds and shoots sprouting from the base to reduce nutrient consumption and keep the plant shape neat and attractive. During the bud formation period, apply quick-acting phosphorus fertilizer 1-2 times to promote larger flowers and more brilliant color.

Growing methods and precautions for the nopal cactus

1. Spring: During the growing season of the nopal cactus, pay attention to sufficient light and timely fertilizing. Apply a fertilizer combining nitrogen and phosphorus once every 10~15 days to promote healthy growth of flowers and leaves. Avoid water accumulation in the pot to prevent root rot. Starting in April, flower buds emerge at the edges of the upper half of the fleshy leaves and gradually swell, and after half a month they bloom fully. If at this time the plant lacks nutrients and its growth is weak, it will not bloom or will bloom less. To prevent this from happening, apply quick-acting phosphorus fertilizer 1~2 times in advance. At the same time, also remove excessive lateral buds and shoots at the base.

2. Summer: During the period of vigorous growth, promptly apply 1~2 top-dressings mainly of nitrogen. This both encourages it to grow new branches and leaves and helps it grow more buds and bloom more next spring. If you want to increase the number of stem segments, you must seize this favorable period to keep buds. In the high temperatures of midsummer, the nopal cactus enters a semi-dormant period. It should be placed in a ventilated, cool, semi-shaded spot, fertilizing should be stopped, watering should not be excessive, and the potting soil should be kept slightly dry, avoiding excessive shade so as to prevent excessive vegetative growth that affects flowering.

3. Autumn: This is the second period of vigorous growth in the year. New leaves gradually age and mature. The management and maintenance methods are basically the same as in spring and early summer from May to June. Apply 2~3 top-dressings, mainly phosphorus and potassium fertilizer. Also increase the duration of light.

4. Winter: After Frost's Descent, the weather turns cold, and the plant needs to be moved indoors to keep warm. It can be placed in a sunny spot indoors, with the room temperature kept at 8°C. Stop fertilizing, restrict watering, and it is best for the potting soil to be on the dry side. Too much moisture will cause the leaves to wilt and fall over and cause root rot. After spring, from mid-March to early April, as temperatures rise, gradually extend the time for opening windows for ventilation and hardening, laying the foundation for later moving it outdoors for maintenance.

Repot the nopal cactus and change the soil once every 1~2 years, which can be done in either spring or autumn.

The living habits of the nopal cactus

The nopal cactus likes a warm and humid environment, avoids direct sunlight, is drought-tolerant, tolerates partial shade, and fears rain. It requires fertile, loose, well-drained neutral or slightly acidic sandy loam. The optimum temperature during the growing period is 20-25°C, the optimum temperature for flower bud differentiation is between 10-15°C, the winter temperature must not be lower than 5°C, and the flowering period is April.

The flower language of the nopal cactus

The nopal cactus looks beautiful, lively and lovely, but its flower language is somewhat sad, because its flower language is remembrance.

Although the nopal cactus looks carefree and blazes with delicate beauty, its flower language is relatively sad. What exactly remembrance is meant to remember, we cannot know. It is just that a beauty like the nopal cactus is already very endearing in form, and with a story attached, no wonder it drives people crazy.
