Peace Lily Propagation: Learn About Peace Lily Plant Division

The following are some interesting facts about Peace Lilies:

1) They have been used for centuries to promote harmony and tranquility.

2) There are over 200 species of peace lilies worldwide.

Most of them belong to the genus Phyllostachys, which means “peace” or “quietness”.

3) Peace lilies are native to tropical regions of Asia, Africa and South America.

They grow best in full sun with moist soil.

4) Peace lily plants produce one flower per year, but they can reproduce several times before flowering stops altogether.

(They don’t stop producing seeds though!)

5) Peace lily flowers have white petals and red stamens.

Their color varies depending on their variety and cultivar.

6) Peace lily plants can live up to 50 years!

7) Peace lily plant is a member of the family Rosaceae, which includes roses, hydrangeas and other members of the same family.

(There are also other types of lilies such as the sedums. The difference between these plants is that the rosaceae family produce fruits and the sedum family do not.)

8) The leaves of the peace lily plant are poisonous if ingested.

They cause vomiting and diarrhea.

9) Peace lily leaves, stems and roots can be used to produce medicine.

They contain ingredients that help relieve pain.

10) The flowers contain psychoactive elements which have a calming effect on people, hence their name.

Peace lily plant division:

One way to propagate peace lily is division. This method involves separating the plant into smaller sections, each with its own root system.

It doesn’t matter whether the entire plant is separated or just the pups; either way you will be able to grow more plants from this one.

When is the best time to divide a peace lily plant?

You can do it at any time of the year. The best season is spring or fall, when the ground isn’t frozen and it isn’t excessively hot. If you do it in the summertime, the plant will have less time to recover before the next growing season. If you do it in the winter, you run the risk of damaging roots with frost, which would impair its ability to survive.

Peace lily plant leaf cuttings:

Peace lilys can also reproduce using leaf cuttings. This method is less complicated than division and doesn’t require a sharp blade.

All you have to do is take a leaf (preferably one that is not flowering, but they will flower sooner or later anyway), and put the lower end in a glass of water. If everything goes well, roots will develop in about a week or so.

When the cutting has developed roots, you will have to transfer it to soil, because these cuttings don’t like “wet feet”. Keep it in a sunny place and water it whenever the soil feels dry.

Before long, it should develop leaves and stems. It’s at this point that you can transfer it to a pot or plant it in the ground.

Peace lily plant diseases and pests:

Peace lilys are prone to few diseases and less likely to attract insects. Most of their problems come from being over watered or too much sun.

If your plant turns brown or yellow, it probably doesn’t have enough water. If it’s leaves have black spots, it may have been infected with crown rot or blight. These problems are common in plants that live in high humidity and warm, wet soil. You can treat crown rot by removing the infected leaves and stems and making sure the soil is well drained. To treat for blight, remove the affected leaves and spray with fungicide.

Peace lilys can also be attacked by aphids which are small (less than 1/4 inch long), soft-bodied insects that come in a variety of colors. They feed by sucking the juices from plants, causing them to wilt and die.

You can treat aphids with an insecticidal soap or a strong blast of water.

You can also treat your plant for mealy bugs. These small insects look like little pieces of white cotton and they tend to live on the leaves of your plant.

You can spot them by looking for little clumps of wax on the leaves. They also produce a sticky residue that drips from the plant, especially between the leaves. Remove the infected leaves and spray with insecticidal soap or neem oil.

Peace lily plants can succumb to scale insects, which produce a hard protective shell as they mature. These appear as small, yellow lumps on your plant.

You can get rid of them by scrubbing them off with your fingers or a cloth or spraying with an insecticidal soap.

Finally, peace lilys are sometimes attacked by spider mites. These are very small arachnids that look like tiny dots crawling on the leaves or ends of stems.

They feed on plant sap and cause leaves to turn yellow or brown and fall off. These too can be removed by hand or sprayed with an insecticidal soap or neem oil.

Peace lily (spathiphyllum)

Spath is one of the most popular plants for offices, relaxation and waiting rooms, hospitals, nursing homes and many other places, thanks to its reliability and reputation as a clean plant (being nearly sterile, it’s less likely to cause allergic reactions).

This tropical perennial grows from a rhizome (underground stem), which produces new leaves from the top and roots from the bottom. Each leaf can grow two to three feet long and up to one foot wide, and in the spring it produces large clusters of small white flowers.

Spath prefers medium light (but can take low light), humid conditions and moderate water. It doesn’t like its feet wet, so it should be planted in a container with holes in the bottom to allow extra water to drain out.

Feed every two weeks with a balanced fertilizer.

Being a sterile plant, it is nearly free of pests and diseases. It can be attacked by mealy bugs, scale and thrips, which can all be treated with the usual chemicals.

The only problem most people have with it is trying to get it to re-flower. Most spath plants are grown in sterile conditions (in vitro) and have no natural knowledge of how to reproduce themselves, so they need a little help.

Repot in the spring, choosing a pot just one size larger than its current one. At the same time, prune back the stems, including some of the oldest ones.

Just remove the oldest and largest stems (no more than one-third) and any tiny new growths that have appeared below them.This tip courtesy of the Missouri Botanical Gardens.

Finally, please note that even though spath is nearly sterile, it’s considered a tropical plant and will not survive long in rooms with freezes. If you live in an area that has cold winters, it’s best to store the container (preferably in an unheated garage or shed) over the winter, and replant in the spring.

Pothos (epipremnum aureum)

Pothos, also called devil’s ivy, is one of the most popular plants around, often used in offices and other busy areas because it’s very tolerant of neglect.

It has semi-woody stems, which produce long vines that can climb on trellises or linking several pots together. It has dark green heart-shaped leaves with light yellow spots.

It grows best in medium light but can also grow in low light. It prefers humid conditions, and should only be watered when the top inch of potting mix is dry to the touch.

This plant can be infected with several pests and diseases, including mealy bugs, scale, vine weevils, aphids, lace bugs, nematodes, and cryptoles. Most can be treated with a neem oil spray or insecticidal soap.
