How to Grow Rain Lilies So They Fill the Pot? First, Understand Their Symbolism and Meaning
Many couples in the throes of romance rack their brains over what special flower to give their partner on a holiday; the usual popular choices like roses and tulips feel a little less special. If you are also fretting over this question, let me introduce you to the "rain lily"!
Rain lilies are perennial herbaceous plants, and their flower language is first love and pure love. Giving them to a partner in the throes of romance is the best way to express the feeling of a couple who respect each other and stay by each other's side day and night. Generally speaking, they are most commonly seen on the flower market as potted plants or planted in the ground. After buying them, if planting in the ground, you can plant them along courtyard walls or under trees; if growing them in pots, you can place them on a windowsill or a desk, as they have high ornamental value.
If grown in a pot, it is not too fussy about its environment and can be placed in a bright spot or a semi-shaded spot. The suitable growing temperature is 20 to 25 degrees Celsius, and it can tolerate cold down to -0 degrees Celsius at most. At around -10°C, it will not freeze for a short time, but if the cold lasts longer, it may freeze to death. The maximum high temperature is 30 degrees. In extreme weather, strengthen water management or place it in a space with a constant room temperature to prevent the plant from being damaged.
As for soil, when planting in the ground, apply plenty of base fertilizer. If growing in pots, once you notice the soil becoming compacted later on, or after about 1 year, you can turn the soil and replace it with garden soil for care. During the growing season, remember to give the rain lily a diluted liquid fertilizer once every two weeks, and apply 2-3 times a year a thin cake fertilizer solution as a top dressing. But please note that the amount of fertilizer should be moderate to avoid burning the roots from over-fertilizing.
The watering principle for rain lilies is to water when dry and stop when wet, keeping the soil moist. In daily care, you can touch the potting soil with your hand; if it is too wet, do not water, because this can easily cause root rot. It is recommended to water once every two days, and after each watering, touch the soil with your hand to check its condition, and do not let it become too dry or too wet.
For pest and disease control, although rain lilies are relatively resistant to pests and diseases, problems such as leaf spot disease and aphids should not be ignored. Once you find that the plant shows abnormalities, such as yellowing leaves or pest damage, take measures promptly; biological pesticides can be used for control.
