How to Grow a Peace Lily? Detailed Guide to Care Methods and Precautions
In recent years, the peace lily has been extremely popular and sought after, not only because it is beautiful but also because it is an especially easy flowering plant to grow, making it the first choice for many friends growing flowers at home. But the fact that the peace lily is easy to grow does not mean it can be left unattended; you still need to understand certain cultivation techniques, so that the peace lily will grow more luxuriantly and vigorously.
How to Grow a Peace Lily
1. The peace lily is fairly shade-tolerant. As long as there is about 60% scattered light, its growth needs can be met, so it can be grown year-round indoors in a spot with bright, scattered light. In summer, 60%-70% of sunlight can be shaded out; direct strong light is taboo, otherwise the leaves will turn yellow, and in severe cases sunscald will occur. In northern winters, greenhouse cultivation can go without shading or with little shading. If the light is too dim for a long time, it will be difficult for the plant to bloom.
2. The peace lily is a heat-loving species and should be cultivated in a high-temperature greenhouse. In winter, the minimum nighttime temperature should be 14-16°C, and the daytime temperature should be around 25°C. Prolonged low temperatures easily cause leaf drop or a scorched-yellow appearance. During the growing period, the potting soil should be kept moist frequently, but avoid overwatering and long-term soggy potting soil, otherwise root rot and plant yellowing and withering are likely.
3. In summer and dry seasons, frequently spray water onto the leaf surface with a fine-nozzle sprayer, and also sprinkle water on the ground around the plant to keep the air moist, which is very beneficial to its growth and development. When the climate is dry and air humidity is low, new leaves will become smaller and yellow, and in severe cases wither, yellow, and drop. In winter, watering should be controlled, and it is best to keep the potting soil slightly moist.
4. Potted peace lilies require loose soil with good drainage and aeration; heavy clay soil must not be used. Generally, a substrate can be made by mixing leaf mold and peat soil with a small amount of perlite; when planting, add a small amount of organic fertilizer as a base fertilizer. Because it grows quickly and has a relatively high fertilizer requirement, liquid fertilizer must be applied once every 1-2 weeks during the growing season; at the same time, provide sufficient water and keep the potting soil moist frequently. During high-temperature periods, water should also be sprayed on the leaves and ground to increase air humidity. If the surrounding environment is too dry, new leaves will become smaller and yellow, and in severe cases wither, yellow, and drop.
Peace Lily Cultivation Methods and Precautions
Peace lily care is nothing more than watering, fertilizing, and sun exposure. Sunlight may not be something people can control, but at least watering and fertilizing are in your hands.
1. Best Fertilizing Method
The peace lily grows quickly and has a high fertilizer requirement. Apply decomposed liquid fertilizer once a month. If you choose solid fertilizer, remember to water once with clear water the next day. In choosing fertilizer, concentrated fertilizer and raw fertilizer are prohibited.
During fertilization, loosen the soil around the peace lily to promote fertilizer absorption, which is beneficial to its growth. In addition, be careful when fertilizing not to sprinkle fertilizer on the leaves, so as to avoid burning the leaves. In summer high temperatures and winter low temperatures, the peace lily grows slowly, so stop fertilizing at these times.
2. Best Watering Method
The amount of watering differs slightly by season. In summer or dry seasons, frequently spray water on the leaves and ground to increase air humidity and keep the leaves fresh and tender.
In autumn and winter, watering should be appropriately reduced, as a low-temperature and damp environment can easily cause root rot! To prevent the peace lily from being damaged by cold due to lower temperatures, pay attention to cold protection and just keep the potting soil slightly moist.
3. Best Potting Soil Replacement Method
Every 1-2 years, the peace lily needs to be repotted. When repotting, prune the plant's root system. Cut off old roots and excessively long roots, remove part of the old soil, and replace it with new soil, which is beneficial for the peace lily to bloom.
In addition, when repotting, divide the plant reasonably according to its size, so that one pot of peace lily becomes two pots.
Does a Peace Lily Need Pruning?
A peace lily does need pruning. Pruning generally falls into three situations.
1. Leaf pruning. Sometimes a peace lily needs its leaves pruned, because as it grows, its leaves become very lush and need timely pruning. Another reason is to inhibit plant growth and reduce nutrient consumption, which also requires pruning.
When pruning, you can use scissors or your fingers to directly remove the growing points on the tender shoots. If the purpose is to reduce nutrient consumption, you can cut off adventitious buds before they mature. After the branches are shortened, no new buds will grow for a long time.
2. Root pruning. Sometimes a peace lily also needs its root system pruned. The main point when pruning is to cut off some old roots and excessively long roots. After pruning the roots, replace with new soil and replant. Root pruning can be combined with repotting.
3. Flower pruning. Flower pruning mainly means pruning the flower stems. Do this after the peace lily has finished blooming. Be careful not to cut off the flower stem directly; just cut off the part that has bloomed, and the remaining flower stem will turn yellow and fall off naturally. If you accidentally cut off the flower stem as well, just be careful not to let the wound get wet before it dries, and basically there will not be any major problem.
Growth Habits of the Peace Lily
It likes high temperatures and high humidity, and is also fairly shade-tolerant. The peace lily (Spathiphyllum) has relatively large leaves and is quite sensitive to humidity. It fears strong light and sun exposure, so in summer provide 60-70% shade, but if light is insufficient for a long time, it will not bloom easily. The soil is best as fertile loam rich in humus. The suitable growth temperature is 22-28°C; from March to September it is 24-30°C, and from September to March of the following year it is 18-21°C. In winter the temperature should not be lower than 14°C; below 10°C the plant's growth is hindered and the leaves are prone to cold damage. During storage and transport of potted Spathiphyllum, the temperature should be controlled at 13-16°C with a relative humidity of 80-90%, and it can tolerate a dark environment for 30 days.
Through the above content, I believe everyone has gained a certain understanding of peace lily cultivation techniques. After all, it is a flowering plant, and if it is not cared for well, it can easily wither and die, but if you pay attention to care methods in normal times, there is basically no problem!
