Detailed Explanation of the Key Points of Cycad Offset Propagation Techniques

    The cycad has an ancient and dignified tree form, with leaves that stay evergreen through all four seasons, lush and green as if about to drip, always full of vitality and energy, giving people an uplifting inspiration, and it is highly favored by everyone. It is suitable for potted appreciation and for decorating public places. Cycad propagation includes seed propagation and offset propagation. Because seeds are difficult to obtain, offset propagation has become the main propagation method for household potted plants.

    1. Offset timing: carry it out in early spring in January and February.

    2. Taking offset buds: cycads that have been cultivated for many years and are growing vigorously often sprout many offset buds at the base of the stem and on the trunk. Among the many offset buds, choose plump ones that are more than 3 years old or that have 4 to 5 leaves as propagation material. This is because such offset buds have a high degree of lignification, contain more nutrients, have strong adaptability, and easily take root and survive. Never choose overly tender offset buds for propagation, otherwise they easily rot and propagation is difficult to succeed. The method of taking buds is: use a sharp small knife to cut the offset bud off from the base where it connects to the mother plant. When cutting, try to damage as little stem skin as possible. Treat the cut offset buds differently according to whether they have rooted: for those that have already rooted, they can be directly planted in culture soil rich in humus, well drained, and highly breathable for management; for those that have not rooted, place them in a cool, ventilated place to air-dry for 2 to 3 days, and after the cut surface is slightly dry, carry out root promotion treatment.

    3. Root promotion: for offset buds that have not rooted, it is not suitable to plant them directly into humus soil at first; they should be planted in plain sand to promote rooting. The planting depth is 1/2 of the height of the offset bud. To prevent the wound from rotting, before planting, coat the wound with plant ash, charcoal powder, or sulfur powder. After planting, water once to keep the sand moist, but do not let water accumulate. After planting, place it indoors in a bright place for care. In about 2 months new roots sprout, and in 3 to 4 months 1 to 2 new leaves emerge.

    4. Transplanting: when the new leaves have fully unfolded from their curled fist-like shape, they should be moved into culture soil for management, otherwise plain sand cannot provide the nutrients needed for plant growth. The culture soil is made up of 45% leaf mold, 20% mycorrhizal soil, 30% river sand, and 5% calcium magnesium phosphate fertilizer. Never use clay as culture soil, otherwise the cycad will suffer root rot due to water accumulation caused by poor drainage.

    5. Management: the management of cycad offset propagation mainly involves light, water, and fertilizer. In terms of light management, the cycad likes light, and especially during the leaf-growing period it must be placed in sunlight, otherwise the new leaves will be slender and thin, reducing their ornamental value. However, it fears scorching sun exposure. In terms of water management, it dislikes water accumulation, so the culture soil should be dry rather than wet, and it should be handled according to the principle of "do not water if not dry, and water thoroughly when watering." During the peak growing season, keep the soil moist frequently, and spray water on the leaves 2 to 3 times every morning and evening. In terms of fertilizer management, the cycad tolerates barrenness and does not have high requirements for fertility conditions. For seedlings, apply a thin cake fertilizer water about once a month, and during the peak growing season, every 20 days alternately carry out foliar topdressing with 0.3% urea liquid fertilizer, 0.2% monopotassium phosphate liquid fertilizer, or 0.1% ferrous sulfate liquid fertilizer.
