Peace Lily Plant Care

Lighting

Light Requirement: High Light (Bright Indirect Light); Low Light Tolerant

Peace lilies thrive in moderate to bright indirect light, but they can also tolerate low light conditions. However, low light may cause slower growth and fewer blooms. If the plant receives too much direct sunlight, it can cause leaf burn, so it is best to place them near a west or east-facing window, or filtered light through a sheer curtain. It is important to note that peace lilies can also adapt to different light conditions and can survive in lower light levels. Therefore, it is recommended to observe the plant's response to the light and adjust accordingly.

Watering

Quick Tip: Water until water comes out of drainage holes. Allow soil to completely dry between waterings. This plant prefers distilled water.

Peace lilies should be watered when the top inch of soil feels dry to the touch. Use room temperature water to water the plant, and soak it thoroughly until water begins to drip out of the bottom of the pot. Be careful not to overwater as this might cause root rot. Peace lilies love to be slightly moist but not saturated. A peace lily should generally be submerged rather than overwatered. Use soft water instead of hard water or fluoridated water to prevent brown tips on the leaves. Your peace lily needs water if its leaves begin to droop, but don't allow it dry out completely in between waterings.

Temperature

Preferred Temperature: 65º - 85º

Peace lily do best when the daytime temperature is between 65 and 85°F (18 and 29°C), and the nighttime temperature is at least 55°F (13°C). It is important not to let the plant get too cold, as temperatures below 45°F (7°C) can hurt the leaves and roots. Peace lily is a tropical plant that likes to be in a humid environment. You can do this by putting the plant on a tray of pebbles with water in it or by using a humidifier. Also, it's important not to put the plant in direct sunlight because it can burn the leaves.

Humidity

Preferred Humidity: 50 - 60%; Moderate Humidity

Peace lilies do best in places with a lot of humidity, the ideal level being between 50 and 60%. To do this, mist the peace lily's leaves with water every day or put a humidifier near the plant. Don't put your peace lily in an area with a lot of drafts because this can cause the humidity to drop quickly, which can cause the leaves to turn brown and crispy. Instead, put the plant in a place where the temperature and humidity are steady and moderate. Make sure the soil stays moist, but not too wet. Overwatering can cause root rot, which is bad for the plant's health as a whole. Water your peace lily once a week or when the top inch of soil feels dry. This will keep the soil at the right moisture level. If you want to increase the humidity around your peace lily, you could group it with other plants or put a tray of water nearby.

Additional Plant Care

Propagation
Peace lily plants can be spread by carefully separating the roots and stems of the parent plant and replanting them in fresh potting soil in separate containers. To do this, first water the parent plant a day or two before dividing it to make the soil easier to work with. Then, carefully take the plant out of its pot, shake off any extra soil, and separate the roots and stems that are clumped together. Cut any tangled or dead roots with a clean, sharp knife or pruning shears. Then, plant each piece in a separate pot with fresh potting soil, water it well, and put it in a warm, bright place that doesn't get direct sunlight. Keep the soil moist but not soggy, and the new plants should start to grow in a few weeks.
Toxicity
"Peace lilies are toxic to humans and pets if ingested, and are one of the most common houseplants poison control is called about. The peace lily contains calcium oxalate crystals, which can cause irritation and discomfort if chewed or ingested. When ingested, it may lead to symptoms such as mouth and throat irritation, drooling, swelling, and potential gastrointestinal distress such as vomiting or diarrhea. Peace lilies can also cause skin irritation or allergic reactions, and direct contact with the plant's sap may cause redness, itching, or a rash. If the sap comes into contact with the skin, it's advisable to wash the affected area with soap and water. When it comes to pets, peace lilies are considered to be toxic to cats, dogs, and other animals if ingested. Ingesting the plant can cause similar symptoms, including mouth and throat irritation, drooling, vomiting, and potential gastrointestinal issues. If you suspect your pet has ingested parts of the peace lily or is experiencing any concerning symptoms, it's best to contact a veterinarian for guidance."
Repotting
When the peace lily is growing, in the spring or early summer, is the best time to move it to a new pot. Choose a pot that is one size bigger and has holes in the bottom for drainage. Put fresh potting soil in the bottom of the new pot. Carefully take the plant out of its old pot and pull out any roots that are dead or broken. Put the plant in the new pot and add soil until it reaches the plant's base. Firmly pack the dirt around the roots and give the plant a lot of water. Keep the plant in the shade for a few days and keep it out of the sun until it gets used to its new pot.
Pruning
To prune a peace lily, use clean, sharp pruning shears and cut off any yellow or brown leaves and dead flowers. It is important to cut cleanly and not hurt the tissue around the cut. Also, peace lily can get very thick and bushy, and trimming it every so often can help keep it in a more balanced and attractive shape. To do this, cut off the tips of the stems just above a leaf node to make them branch out and grow fuller. Peace lily can also be kept healthy and full of life by dividing it and repotting it every few years. You can prune the plant whenever you need to, but don't prune it in the winter when the plant is sleeping. With the right pruning, peace lilies can keep their good looks and continue to grow for many years.
Fertilizing
To feed a peace lily plant, first choose a balanced, water-soluble fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Before you put the fertilizer on the plant, you should water it well and dilute the fertilizer to half the recommended strength. Apply the fertilizer to the soil around the plant's base with a watering can or spray bottle, being careful not to get any on the leaves. During the growing season, which usually lasts from spring to early fall, do this every two to four weeks. Don't give the plant fertilizer when it's sleeping in the winter. Too much fertilizer can hurt the plant, so it's important to follow the directions on the package and not use too much. If the leaves start to turn brown or black, cut back on how often you feed them or make the solution weaker.
Soil
Peace lily plants do best in loose, well-draining soil that holds some water but doesn't get soggy. Equal parts peat moss, perlite, and vermiculite should make a good soil mix for peace lily plants. Peat moss helps keep water in the soil, and perlite and vermiculite help water drain away. Adding a small amount of compost or well-rotted manure can also help provide the plant with the nutrients it needs to stay healthy. The pH of the soil should be somewhere between 6.0 and 6.5. To keep the plant from getting root rot, it's important to make sure the soil has a lot of air in it.

Fallen leaves can become something genuinely useful for your plants, called leaf mold, but it's not the nutrient boost the word "feed" might suggest.
