How to Propagate Peace Lilies? A Detailed Guide to the Latest Propagation Methods

The peace lily (Spathiphyllum) has become a new generation of indoor potted plants in recent years. It is distributed throughout China, has high ornamental value, and is also very popular with many people. Therefore, its planting area in China is now very large, and when we grow peace lilies, propagation is something we need to pay special attention to. So how should peace lilies be propagated? Below, the editor has brought you the propagation methods for peace lilies. Let's take a look!

1. Division propagation

Generally, division propagation of peace lilies can be carried out all year round, but care should be taken to avoid periods of high and low temperatures. It is also best to do it from March to May, when the survival rate needs to be high. First, choose a high-quality two-year-old plant, then in early spring, when the plant sprouts, dig out the entire plant. Clean the soil off the roots and properly prune the rhizomes. Then cut the rhizome apart from the base of the plant clump, keeping about 3 leaves per clump, and do not damage the roots. Then directly plant the divided plants, maintain a semi-shaded environment, and be sure to loosen the soil appropriately to improve soil permeability.

2. Seed propagation

Seed propagation first requires artificial pollination, and then the seed collection work must be done well. Before sowing, the soil should be exposed to the sun for disinfection to eliminate pathogens and pests in the soil. Then put the seeds in warm water at about 40 degrees and soak them for about 12 hours, then remove them, dry them, and sow. The sowing method is mainly hole sowing. After sowing, cover with a layer of fine soil, and control the temperature at about 26 degrees. They will germinate in about four weeks, but be sure to control the temperature well. If the temperature is too low, the seeds are very likely to rot. However, because obtaining peace lily seeds is rather troublesome, and it takes about three years to flower, seed propagation is not commonly used.

3. Tissue culture

Tissue culture is mainly widely used in large-scale propagation. It mainly involves propagating peace lilies through explants such as stem tips and leaves. First, soak the explants of the peace lily in alcohol for about half a minute, then place them in mercuric chloride for ten minutes for disinfection. Then place them in MS nutrient solution, and in about 40 days callus tissue and adventitious buds will form. Then use hormones to induce rooting. After rooting, culture them for about one month, and when they reach a height of about two centimeters, carry out hardening-off work to improve the adaptability of the seedlings. Finally, prepare a substrate with fine sand and perlite for transplanting.

The above is a brief introduction to peace lily propagation methods. When propagating, everyone should choose a suitable propagation method according to their own planting scale, planting methods, and other actual conditions. That is all for today's introduction.
