You can also deadhead the flowers to promote new growth.

With a little care, Peruvian lilies will thrive in your garden for many years.

These beautiful flowers are a great way to add color and interest to your landscape.

Common Problems With Peruvian Lily

Why Have My Plants Stopped Flowering?

Peruvian flowers are prized for their beautiful blooms, which come in a variety of colors. However, it’s normal for these flowers to stop blooming after a few years. This usually happens when the plants are 5 or 6 years old.

When this happens, it’s time to pull up the tuberous roots and split them. This will help the plant to produce new growth and keep blooming for many years to come.

With proper care, Peruvian flowers can provide years of enjoyment.

Stems and Leaves Wither, Even When Plants are Well-Watered

Root rot is a common problem for gardeners, especially during wet and warm weather conditions. The condition is caused by fungi that attack the roots of plants, causing them to rot.

Root rot can be prevented by taking steps to improve soil drainage and make sure the roots have access to air.

One way to improve drainage is to add organic matter to the soil, such as compost or peat moss.

This will help to aerate the soil and reduce compaction. In addition, making sure the roots are not waterlogged by providing adequate drainage will help to prevent root rot.

Plants Won’t Stay Upright

They have long, thin stems and a lot of flowers. Usually, they will turn over. This is a common problem when the species are grown as cut flowers, but it is easy to fix by just staking the flower stems.

How to Get Peruvian Lily to Bloom

It is easy to grow Peruvian lilies, and as long as they get enough light and water, they usually bloom well. However, it is important to remember to fertilize them regularly, as this will help encourage more blooms.

A balanced fertilizer like 6-6-6 applied every few weeks should be sufficient. After about five or six years, it is not uncommon for Peruvian lilies to produce fewer blooms.

When this happens, the best course of action is to dig up the root clumps and replant them to create new plants. By following these simple tips, you can enjoy the beauty of Peruvian lilies for many years to come.

Common Pests & Plant Diseases

Although they are beautiful and easy to care for, Peruvian lilies can sometimes be affected by pests. Aphids and thrips are two of the most common problems.

These small insects can cause damage to the leaves and flowers, and they can also spread diseases from one plant to another.

However, these pests are usually not a big problem if they are dealt with quickly. The best way to remove them is to use a strong stream of water to knock them off the plant.

You can also use insecticidal soap or neem oil to control aphids and thrips.

If you notice any unusual spots or discoloration on the leaves, it is important to remove the affected leaves immediately so that the disease does not spread.

With a little care, Peruvian lilies will continue to thrive in your garden.


People who live in warmer areas can grow Peruvian flowers by digging up the tubers and storing them for the winter. Before the ground freezes in the winter, you should work in your garden in the fall.

The soil should be broken up, and then the tubers should be put into paper bags with peat and stored in a cool, dry place (35 or 41°F) for the winter.

When the soil has warmed up to at least 60°F in the spring, plant again.

People who live in zone 8–10 don’t need to do anything special to care for their Peruvian lilies during the winter—just cut back the dead leaves.

Zone 7 is a transition zone, so to keep the plants from dying in the winter, dry mulch must be spread over them.

Peruvian Lily Care

As any gardener knows, soil is essential for growing healthy plants.

Not only does it provide nutrients and support for roots, but it also helps to regulate moisture levels and prevent weed growth.

However, soil can also be quickly eroded by wind and water, damaging plant life and making it difficult for new seedlings to take root.

One way to help prevent soil erosion is to maintain a healthy lawn. Grassroots help to hold the soil in place, and the dense network of blades helps to deflect wind and water.

In addition, lawns help to slow down the flow of rainwater, giving the ground a chance to absorb the water before it runs off. As a result, a well-tended lawn can play an essential role in preventing soil erosion.
