Peace Lily

The peace lily is one of the popular and remarkable tropical, evergreen plants.

It usually grows well on the forest floor – a perfect spot where it can receive dappled sunlight and proper moisture.

This plant bears white flowers that begin to occur in the early summer and keep blooming year-round as long as the required conditions are perfect.

Most peace lilies can grow up to 16 inches tall when kept indoors. However, outdoor cultivars can be larger.

The leaves can even reach 6 feet in height. Like most tropical plants, this variety is not cold-hardy.

It means if you want to grow the plant outdoors, make sure your place is at USDA zones 10, 11, which provide warm, humid climates.

How to Plant Peace Lily

Use just enough so that once repotted, the top of the plant's root ball will be about ½ to 1 inch (1-2.5 cm.) below the rim of the container. The goal is for the plant to sit at the same level it was situated in the old pot; burying the plant too deeply may cause the plant to rot.
Planting Peace Lily

The peace lily is a great choice when it comes to incorporating natural elements into your home and office.

This plant is not fussy, which is perfect for beginners.

You can grow the plant both indoors and outdoors because it loves medium to low light.

If you place it in a spot that receives more light, it will produce more flowers and white spathes.

On the other hand, if it is in a low-light area, it will look like a common foliage plant. Planting a peace lily is not that hard.

Here are the steps.

  • Pick a flowerpot whose size is one-third larger than its root ball. Fill it with well-draining and all-purpose potting soil.
    You can also top it with sphagnum moss, which is renowned for being good at retaining water.
  • Once the soil is ready, place your plant in the pot. Add more compost around the root ball.
    Then, water it well and give it some time to drain.
  • Place the plant in a humid room like a bathroom because it provides a similar environment to its natural habitat – the tropical forests.

Peace Lily Soil

Peace lilies prefer a soil that can mix drainage and moisture retention. Blended potting mixes with texture are common for peace lilies, especially ones with perlite, peat moss, coir, or loam.

Although the peace lily is not fussy, it can thrive well if you grow it in good quality soil. Besides, every potting mix is different.

This variety belongs to a member of the araceae family, meaning it prefers a balanced soil.

It has to be able to retain moisture while keeping draining well. This way, it stays evenly damp without being soggy.

Unfortunately, many potting mix soils drain quickly, resulting in drying out the roots. Some of them even retain too much moisture, which is not good for the root.

Therefore, you need to consider buying a special mix for araceae or making it yourself.

  1. Easy Potting Mix Soil for Peace Lily

Plant peace lilies in Miracle-Gro® Indoor Potting Mix for great results. Keep the soil consistently moist but not soggy. A month after planting, feed plants with Miracle-Gro® Indoor Plant Food. Repot when the plant's roots have completely outgrown its container.

If you do not have a specialty mix for araceae at home, you can use 2 parts regular indoor cactus mix or potting mix.

Then, concoct it with one-part perlite or bark. This way, you can help increase aeration.

This combination might not be the best when it comes to a long-term solution because it retains more moisture.

Fortunately, the bark can help you improve drainage. Therefore, it really does in a pinch, especially if you need to pot your plant immediately.

Caring for Peace Lily

The peace lily should be close to, but not directly under a window in a warm room in your house where it will benefit from indirect sunlight. North or West facing windows are best as these do not allow direct sunlight all day.
Caring Peace Lily

The most important part is to know everything about peace lily care indoors and outdoors.

Although it is a friendly houseplant for anybody, including beginners, you still need to learn what to do to make it thrive.

First, you need to think about where to place your plant. This plant loves humidity. Therefore, you should mist the leaves regularly.

For an easier alternative, you can put the pot on top of a moistened tray with gravel to increase humidity around it.

As a tropical plant, it will thrive in temperatures above 70 0F (21 0C). In its natural habitat, peace lilies live on the forest floors.

Thus, keeping them out of direct afternoon sunlight will be a terrific idea.

Still, keep the spot well-lit and bright. Placing your plant in an east-facing window is a wise option because you allow it to get bright morning sun.

Remember not to let it expose to intensive mid-day rays, though.

Peace lilies can be put up with dry soil for a short period. If the leaves are getting brown, it means you have let them dry for too long.

Thus, it is time for you to water the plants.

If you want your peace lilies to grow well, you should do regular watering. It is to keep the soil moist.

Do not overwater it either, though. Consider using filtered, room temperature water if necessary because this variety is prone to fluoride.

You do not need to fertilize this variety frequently as it is not a heavy feeder.

Apply fertilizer every 6 weeks or so starting in late winter will be enough. Consider repotting this plant annually in the spring so that it gets refreshed soil.
