Cultivation methods and precautions of orchid canna

1. Lighting

This plant loves sunlight, so it needs very sufficient light, at least 5 hours of sunlight a day. Plants grown in a shady environment will flower later. If you place it in a darker place after it blooms, you can extend the flowering period and make it easier to view.

2. Temperature

In order for this plant to be healthy, the most suitable temperature is between 15-30 degrees. In order to extend its viewing time, the temperature can be lowered appropriately when it blooms, but it should not be lower than 10 degrees, which can extend its flowering time. When the temperature is above 40 degrees, it is best to place it in a cool and unobstructed environment. Before and after the frost, you need to place it in a place between 5-10 degrees so that it can safely spend the winter.

3. Humidity

This plant tolerates moisture very well and needs to have its leaves sprayed with water 1-2 times a day. In addition, watering should be done thoroughly to ensure the plant's water needs. In the hot summer, it is not advisable to use too cold water for watering, as it can easily cause the leaves to burn. In addition, if it is too dry, the same symptoms will appear.

4. Fertilization

In addition to using a certain amount of base fertilizer before planting, fertilizer should also be applied 3-4 times a month during the peak growth season of the plant. If flower buds have not appeared 20-30 days before flowering, you can spray 0.2% potassium dihydrogen phosphate on the leaves to promote flowering. This plant sometimes has symptoms of wilting or yellowing leaves, generally due to excessive ferrous sulfate or drought. In the hot summer, be careful not to apply fertilizer too concentratedly, otherwise it will burn the roots and stems of the plants and cause their death. Fertilization should be stopped during winter.

5. Soil

This plant does not have high requirements for soil conditions, it only needs to be loose, fertile and easy to drain water. It can grow normally regardless of sandy or clay soil. The potting soil needs to be a compound of leaf mold, garden soil, peat soil and mountain mud. Alternatively, you can use leaf mold, garden soil, and rice husk ash in a ratio of 2:3:1, and add a small amount of bean cake and bone meal. The soil should be kept moist at all times to allow plants to grow. When the fifth leaf grows, it is necessary to add fertilizer in time.
