How to care for Cereus peruvianus in autumn
Today's sharing: How to care for Cereus peruvianus in autumn and related green plant and flower care techniques for autumn maintenance of Cereus peruvianus, the specific contents are as follows:
Cereus peruvianus is a kind of cactus flower plant, with flat and elongated leaves with small spines, and the top is in an inverted triangular shape, similar to ancient command arrows. The flowers are large and resemble those of epiphyllum oxypetalum, but they are more colorful and loved by countless flower enthusiasts. Autumn is a crucial period for caring for Cereus peruvianus. If you do four steps well, it will bloom beautifully with full pots the following year.
1. Supplement lighting
Cereus peruvianus is a shade-loving plant, and wild Cereus peruvianus grows under the shade of tall trees, developing a habit of not liking strong light. If exposed to strong sunlight for a long time, the leaves of Cereus peruvianus will quickly turn yellow and wither. Therefore, shading is required during the summer.
However, as autumn approaches, the sunlight becomes softer, and the ultraviolet rays weaken significantly, not burning the leaves. At this time, Cereus peruvianus grows rapidly and requires a lot of energy. In autumn, we need to expose Cereus peruvianus to more sunlight, placing it in a position with ample direct light, allowing it to accumulate energy through photosynthesis. This will result in more leaves, a more developed root system, and an increased number of flowers the following year.
2. Control watering
The roots of Cereus peruvianus require high soil permeability. If the soil is too moist, it can quickly cause root rot, and over time, the stems and leaves will also soften and rot. Although Cereus peruvianus grows rapidly in autumn, watering should not be too frequent or excessive. The principle of watering Cereus peruvianus in autumn is to water when the surface of the potting soil becomes white and dry. When the temperature drops below 10 degrees Celsius, Cereus peruvianus enters dormancy, and watering should be further reduced.

3. Supplement fertilizer
In spring, Cereus peruvianus grows many new leaves, which are relatively small. In summer, when Cereus peruvianus is in bloom, flowering consumes a lot of nutrients, but to avoid burning the seedlings, we can only apply a little thin fertilizer in summer. By autumn, the fertilizer in the soil is mostly used up, but we want to turn the spring leaves into old leaves because Cereus peruvianus only grows flower buds on old leaves. To quickly turn new leaves into old leaves, we need to supplement some fertilizer to promote rapid leaf maturity.
Fertilizers high in potassium content have the effect of promoting leaf maturity and aging. The most common potassium fertilizer on the market is potassium dihydrogen phosphate. Using potassium dihydrogen phosphate as an example, mix it with water at a ratio of 1:1000, stir well, and spray it on the stems and leaves of Cereus peruvianus, pouring the remaining solution into the roots. Use it 2-3 times a month and stop fertilizing after winter.
Pinching leaves
In autumn, Cereus peruvianus will also sprout new leaves. Sometimes, too many new leaves can compete with old leaves for nutrients. To help the spring old leaves mature quickly, we need to pinch off some of the new buds and leaves. After pinching the new leaves, combined with potassium fertilizer supplementation, the leaves can quickly mature and age, increasing the number of flowers the following year.
The above is a specific introduction on how to care for Cereus peruvianus in autumn and related autumn maintenance techniques for Cereus peruvianus, for netizens to refer to and learn from.
