Cultivation techniques of Anthurium andraeanum

1. Choose soil with good air permeability, soft and fertile rotten leaf soil, sand and perlite can be mixed evenly, and the pH value should be controlled between 5.2 and 6.1.

2. You can choose ceramic flowerpots or plastic flowerpots. The size of the flowerpot should be planted according to the size of the plant. if the ramet seedling has 2-4 leaves, it can be 8-9 cm in diameter. When the pot is full, you can transplant it to a flowerpot with a diameter of less than 20 cm.

3. Anthurium andraeanum is fond of moisture. At ordinary times, attention should be paid to keeping the soil moist. In the seedling stage, due to the weak root system, shallow distribution in the substrate and not resistant to drought, water should be sprayed 2-3 times a day after planting, to keep the matrix moist often, to urge it to draw more new roots early, and to pay attention to the dry humidity of the pot substrate; plants grow fast in the middle and big seedling stage, and water supply must be sufficient; watering should be reduced during flowering, and phosphorus and potassium fertilizer should be applied to promote flowering.

4. according to the principle of applying thin fertilizer and more fertilizer to Anthurium andraeanum, there is no need to apply fertilizer in dormant period, and the effect of root fertilization is better than that of foliar topdressing. It can be irrigated once every 2 days in summer and once more when the temperature is high, and it can be irrigated once every 5-7 days in autumn.

5. Anthurium andraeanum should not be exposed to strong light and should be cultivated in proper shade throughout the year. It should be properly shaded in spring, summer and autumn, especially 70% shading in summer. Direct sunlight will make the leaf temperature higher than the air temperature, and if the leaf temperature is too high, there will be burns, scorched leaves, bud discoloration and slow leaf growth.

6. On cloudy days, the temperature should be 18-20 ℃ and the humidity should be between 70% and 80%. On sunny days, the temperature is 20-28 ℃ and the humidity is about 70%. In short, the temperature should be kept below 30 ℃ and the humidity should be above 50%. The indoor temperature in winter should be controlled at 15-20 ℃.

7. Prune diseased and withered leaves in time. If the leaves are too dense, cut off some old leaves.

8. Ramet is carried out from April to May each year, the Anthurium andraeanum is removed from the flowerpot, the root system with 3-4 leaves is cut off, and the lateral plant is cut off and replaced in a flowerpot. Put it in a ventilated and semi-shaded place, and then put it in the south of the room near the window after survival. Cuttings can also be carried out to cut off the old branches and trim the leaves. Every 1-2 nodes are seedlings, either flat or straight, inserted into the soft and fertile soil. The root system can sprout in about a month.

The cultivation of Anthurium andraeanum is relatively simple, mainly paying attention to the supply of watering, temperature and light.
