Cycas like sunshine, but they are also tolerant of semi-shade. It grows well in warm, humid and fresh air. Not hardy, potted plants are used in the northern part of the Yangtze River basin. Generally speaking, it is not suitable to buy too large plants for planting Cycas at home, and the medium-sized pots with a diameter of 20 ~ 30 cm are generally selected for flowerpots. Cycas cultivation soil is a kind of slightly acidic sandy cultivation soil with rich humus, loose fertility and strong permeability. The bottom hole of the flowerpot (barrel) should be large, and a layer of broken tiles should be laid at the bottom of the flowerpot as a drainage layer to prevent root rot.
The cultivation methods and matters needing attention of cycads particularly emphasize the following aspects:
1. After planting Cycas, water it, keep it in the shade for half a month, and then move it to the sunny place of the north wind for maintenance. Always keep the soil wet, but not too wet. Generally, water can be poured once every two days from April to May. Cycas are not resistant to water stains, so pay attention to timely drainage after rain.
It is said that the growth and development of Cycas need the supply of iron in the soil. If it doesn't grow well, adding some iron powder to the soil can restore it to health. Some people simply put nails into the body of Cycas, which can also have a good effect. Might as well try.
3. Iron and iron are vulnerable to scale insects. Scale insects mostly hide on the back of lobules, and sooty blotch is easy to occur in poorly ventilated environment. Therefore, attention should be paid to ventilation and timely medication.
4. Cycas cycas only grows 1 leaf every year. When the new leaves expand and mature, cut off the lower old leaves and keep 2 ~ 3 leaves, so it is not necessary to prune them frequently. Even transplanting or changing pots does not require too much pruning. When the leaves are damaged by pests and diseases, the natural environment is harsh and yellow, they should be cut off in time.
5. Most cycads raised at home are cultivated into bonsai. The cultivation methods and precautions of Cycas guide you to cultivate seedlings of Cycas into mature plants. The yellowing of Cycas leaves is often related to water and fertilizer, so we should check these factors one by one.
