How Often to Water Cymbidium goeringii? A Detailed Guide to Watering and Fertilizing
Cymbidium goeringii is surely a flower that many people are familiar with; it is a well-known flower variety in our country. The leaves of Cymbidium goeringii are slender, and it blooms, with flowers commonly seen in yellow, bearing some spots. Many people grow Cymbidium goeringii at home, but when growing it, its fertilizer and water techniques are something many people want to understand clearly.
How to Water Cymbidium goeringii (How Often to Water)
1. Watering the roots. If watering by pouring, pour along the edge of the pot; this way it takes many rounds to soak the soil through. If watering by sprinkling, you can wet the entire area around the plant and let the water seep into the soil, but be careful not to sprinkle into the heart of the leaves, otherwise the heart easily rots. You can also place the potting medium together with 4/3 of the pot into water; the water will quickly soak through the soil, but be careful of bacterial invasion.
2. Watering the leaves. If using spraying, you can spray directly onto the leaves; they can absorb water through their stomata. If increasing humidity, you can raise the moisture in the air, place some water basins under the orchid rack, or use a humidifying pump.
How to Fertilize Cymbidium goeringii
1. It has two fertilization routes: one through the soil, and one through the leaves. Its growth rate is relatively slow, and generally only a small amount of fertilizer is needed. In spring and autumn, when it grows relatively quickly, give it alum fertilizer water once a week; it must be fully decomposed. No fertilizer is needed in high temperatures or severe winter.
2. It is best to use organic fertilizer; fertilizing the leaves can supplement other trace elements, preferably once every half a month during the peak growing season. If its leaves are very glossy, it means it is not lacking fertilizer; if they are rather dull, then fertilizer is needed.
3. When fertilizing it, pay attention to the sufficient combination of phosphorus, nitrogen and potassium, as well as the absorption of trace elements, and be careful not to apply too much ferrous sulfate. The fertilizer should be even and effective, able to provide what it needs for growth.
How to Make Cymbidium goeringii Bloom at New Year's Day
1. Light factor. Cymbidium goeringii generally prefers a cool, shady environment; it is a shade-loving plant and normally should not be exposed to too much sunlight. In order to speed up its blooming, we give it appropriate shading treatment: 3 months before it is about to bloom, shade it at about 90 percent. And lower the temperature to below 12 degrees C, which can make it mistake this for the cold winter state, thus causing it to enter the vernalization stage early; doing so can make it bloom nearly a month earlier.
2. Temperature factor. Suitable temperatures can also greatly catalyze the growth rate of Cymbidium goeringii. Cymbidium goeringii does not like temperatures that are too high; when the temperature of its environment is higher than 15 degrees C, its normal blooming is greatly affected, almost to the point of stopping growth. Cymbidium goeringii grows fastest at 5 degrees C to 10 degrees C, and in that range the blooming speed is greatly accelerated.
What to Do When Round Disease Spots Appear on Cymbidium goeringii Leaves
1. After the plant is infected by pathogens, the pathogens overwinter as mycelium on the diseased leaves of the remaining plant, so once a diseased plant is found it should be destroyed immediately.
2. Strengthen care. In daily care, pay attention to ventilation and light transmission, and do not plant too densely. Pay attention to the indoor temperature; do not let it become too stuffy and hot. In rainy seasons, avoid torrential rain washing and avoid freezing damage.
3. Spray pesticides in time for prevention and control; especially in the rainy season, spray 50% carbendazim wettable powder at 500 times dilution or 50% thiophanate wettable powder at 500 times dilution, once every 10 days or so; spraying 3~4 times is enough to see results.
The fertilizer and water methods for Cymbidium goeringii are actually not difficult. Fertilizing must be stopped in both winter and summer; only in this way can Cymbidium goeringii grow well. If during cultivation you want to change its flowering period, you can use some techniques, generally starting with aspects such as light and temperature.
