For the peace lily, I believe flower lovers are no strangers to it. Its flowers are pure white and its appearance is beautiful, making it a rare excellent choice for indoor cultivation. It is understood that the peace lily is very easy to grow, whether in soil or in water, but no matter which method is used, root rot can occur. So what should be done when a peace lily has root rot?

1. What to Do When a Peace Lily Has Root Rot: Find the Cause

The peace lily likes a warm, humid, semi-shaded environment, with an optimal growth temperature of 20-28°C, so it can be grown both in soil and in water. But whether in water or in soil, root rot can occur. So what should be done when a peace lily has root rot? Today, I bring you a complete guide to the causes and treatments of root rot in soil culture and water culture.

(1) Causes and Treatment of Root Rot in Water-Cultured Peace Lilies

At home, water-culturing a peace lily is very good, as it is both attractive and can avoid insects flying around in the soil in summer. However, one problem with water culture is root rot. If the water has not been changed for a long time, root rot is very likely to occur.

Solution: Once root rot is found, take the plant out promptly and cut off the rotten roots. When cutting off the rotten roots, be sure to do it thoroughly. If the stem also has rotten parts, cut them off too. After cutting, let it air-dry in a ventilated place for two to three hours. If you have potassium permanganate, you can disinfect the cut after it has healed.

Check for recurrence: Then place the treated plant back into clean water. Note that at the beginning, do not rush to add nutrient solution. After re-water-culturing, be sure to change the water every few days and check whether the roots have rotted again. If there is no problem, then the root rot problem of the water-cultured peace lily has been solved.

(2) Causes and Treatment Methods of Root Rot in Soil-Cultured Peace Lilies

Water-cultured peace lilies are very prone to root rot, but soil-cultured ones rarely have this problem unless you overwater them. At this point, you can observe that if the peace lily's leaves gradually become wilted or lose their vitality (if it has not gone too long without watering), then it is very likely root rot.

Solution: First, lift the peace lily out of the soil. If there is soil, it may be hard to see clearly, so you can slightly clear away the soil around the roots, and then likewise cut off the rotten roots. If necessary, disinfect them.

Change the soil: At this point, it is best not to reuse the soil in the pot, because since there was root rot, it is possible that remnants of rotten roots remain in the soil. So if conditions allow, change the soil. If you really have no soil to replace it with, you can disinfect the soil before using it again.

Observation: Wait until the wounds on the treated roots have healed, then plant it into new soil. Water it well and observe every few days. If the growth looks decent, it means the rescue was successful.

That is all for the root rot problem of the peace lily. In fact, based on the above, everyone should have noticed that whether in water culture or soil culture, root rot is related to water, so in our daily care, we must pay attention to the method of watering.

Peace Lily Water Culture Methods and Precautions

The peace lily is also known as spathe flower, bracteate taro, etc. It is an important ornamental flower in the world. Water-culturing a peace lily allows you to admire both its tender white roots and the cute little fish swimming among the roots. It is truly delightful. Now let us take a look at the water culture methods for peace lilies!

Peace Lily Water Culture Methods

1. Wash the glass bottle clean and wash the pretty little stones clean. Place the stones on a small filter. You can buy one of these devices at a flower shop or a utensil shop. Fill the glass bottle with water and put the peace lily into the bottle. Be careful to prevent the leaves from being rubbed off.

2. Because the peace lily fears strong direct sunlight and likes water, in summer, spray some water on its leaves every other day.

3. Once the peace lily has grown some roots and stems in the glass bottle, check whether its roots have any rotten areas, and remove them promptly if so.

4. If the leaves of a water-cultured peace lily turn yellow, and the yellowing is slight, it can continue to be grown in water. If the yellowing is severe, it must be transplanted into soil for cultivation.

Precautions for Water-Culturing Peace Lilies

1. For water changes, in hot weather do it every 15-20 days; in cold weather about once a month. The water level should just submerge three-quarters of the root system. When changing the water, add a few drops of nutrient solution specially for water-cultured flowers.

2. Normally, scattered light is sufficient. Avoid light in summer, and avoid direct strong light.

3. Use nutrient solution for foliage plants.

4. Spray water on the leaves appropriately to increase air humidity. If using tap water, it should be drawn in advance and left in the air for more than one day to fully dissolve oxygen and release chlorine. When changing the water, wash away the mucus on the roots and cut off rotten roots and scorched leaves.

5. Choose a flowerpot with a relatively large bottom, as this makes it easier to survive.

Yellowing Leaves of Water-Cultured Peace Lilies

1. Dry air: Peace lilies need relatively high growing humidity. If the air is too dry, it can cause leaf wilting. This can be solved by increasing spraying or sprinkling water on the floor of the environment. Covering it with a transparent plastic bag also works, but when the light is good, it should be ventilated slightly or a hole should be opened at the top of the plastic bag for ventilation, otherwise the temperature inside the bag will rise sharply.

2. Nutrient deficiency: As we all know, in the early stage of plant growth, nutrients are absorbed from the soil. Over time, the nutrients in the soil will decrease, causing malnutrition. With too much fertilizer and freezing damage, the leaf tips easily turn yellow. At this point, nutrient solution should be supplemented in time.

3. Improper lighting: Peace lilies need relatively good light in winter and early spring, and should not be kept in shade. When the light gradually strengthens, shade should be increased gradually. If it has been enjoyed in a shaded place, do not directly place it in sunlight for exposure, otherwise it will become uncomfortable due to the rapid change in environment, showing wilting, yellow leaves, or even death. Peace lilies should be kept year-round indoors in a place with bright scattered light.

4. Unsuitable temperature: This generally does not happen easily. Yellowing leaves in peace lilies mostly occur when the temperature is below 5°C or above 35°C. Providing sufficient light conditions not only helps the leaves become dark green, but also helps them overwinter.

5. Pest infestation: If there is damage from mite pests, the leaves of the peace lily will show adverse symptoms such as wilting, faded luster, and yellowing and withering. Miticides can be sprayed for prevention and control, such as dicofol, hexythiazox, pyridaben, etc.

Can Peace Lilies Be Grown in Water? Peace Lily Water Culture Methods

The peace lily is a common indoor potted plant and also an excellent foliage plant. Peace lilies can purify the air and help with dry nasal mucosa. The benefits of peace lilies should not be underestimated. So everyone asks, can peace lilies be grown in water? Today let us learn about the water culture methods for peace lilies.

Peace Lily Water Culture Methods

Water-culturing peace lilies must have a suitable environmental temperature: the growing temperature for water-cultured plants is 5°C-30°C, and they can grow normally within this range.

Water-culturing peace lilies must have suitable light: the light for water-cultured plants should mainly be scattered light, and it is not absolutely necessary to expose them to the sun. In summer, direct sunlight should be avoided as much as possible.

Water-culturing peace lilies must involve frequent water changes and cleaning of the flower roots: for water-cultured plants, change the water about once every 7 days in summer and about once every 10-15 days in winter, adding a few drops of nutrient solution specially for water-cultured flowers (prepare the nutrient solution concentration according to the instructions). The containers used for growing water-cultured plants easily grow moss, which affects the ornamental value of the roots and also consumes oxygen in the water. When changing the water, first wash away the mucus on the flower roots with clean water, and cut off old roots and rotten roots. Also scrub the moss off the container and roots. Each time you change the water, the water level should preferably submerge 1/2-2/3 of the root system, and the remaining root sections can be left exposed to the air.

Water-culturing peace lilies must pay attention to moisture retention and spraying foliar fertilizer: to prevent the leaves from drying out, in daily care, spray the leaf surfaces with clean water to retain moisture. It is best to spray foliar fertilizer once a week, which can not only provide nutrients to the leaves and increase leaf luster, but also help resist low temperatures in winter.

The above are the water culture methods for peace lilies introduced for everyone. I hope they can provide some help to flower enthusiasts and beginners who like peace lilies.
