Alstroemeria Care: How to Keep Your Plant Healthy and Blooming

alstroemeria care

Peruvian lilies, also known as Alstroemeria, are beautiful and vibrant flowers that are native to South America.

They are popular among gardeners and florists alike for their striking colors and long-lasting blooms.

Peruvian lilies come in a variety of colors including pink, yellow, red, orange, and white. They are also available in different patterns such as speckled, striped, and spotted.

Peruvian lilies are easy to grow and care for, making them a great addition to any garden or indoor space.

All About Peruvian Lily

Peruvian lilies are herbaceous perennial plants that belong to the Alstroemeriaceae family. They are native to South America, particularly Chile, Brazil, and Peru.

The flowers of the Peruvian lily are trumpet-shaped with six petals that are arranged in a spiral pattern.

The flowers grow on tall stems and can be up to 2 inches wide. The leaves of the Peruvian lily are lance-shaped and can be up to 6 inches long.

When to Plant Peruvian Lily

Peruvian lilies can be planted at any time of the year, but the best time to plant them is in the spring.

This will give the plants enough time to establish themselves before the hot summer months. If you live in a colder climate, it is best to plant Peruvian lilies in the late spring or early summer.

Light & Temperature

Peruvian lilies prefer bright, indirect sunlight. They can tolerate some direct sunlight, but too much can cause the leaves to burn. If you are growing Peruvian lilies indoors, place them near a sunny window that receives bright, indirect light for most of the day.

If you are growing them outdoors, make sure to provide some shade during the hottest part of the day. Peruvian lilies prefer moderate temperatures between 60-75°F (15-24°C). They can tolerate higher temperatures, but it is important to make sure they do not dry out.

In colder temperatures, the plant may become dormant and stop producing blooms. If you live in a colder climate, you can grow Peruvian lilies as annuals or keep them indoors during the winter months.

Water & Humidity

Peruvian lilies prefer moderate watering. Make sure the soil is evenly moist, but not soaking wet. Overwatering can cause root rot and other diseases, so it is important to let the soil dry out slightly between watering.

In hot and dry conditions, you may need to water more frequently to prevent the plant from drying out. Peruvian lilies do not require high humidity, but they do appreciate a little bit of moisture in the air.

You can increase humidity around the plant by misting it with water or placing a tray of water near the plant. Avoid getting water on the leaves as this can cause fungal diseases.

As previously mentioned, the right soil mix is crucial for the growth and health of your Peruvian lilies. In addition to a mix that contains peat moss, perlite, and sand, it's also important to ensure that the soil is free of any rocks or debris that could hinder drainage.

If you're planting your Peruvian lilies in the ground, consider mixing the existing soil with some organic matter like compost or well-rotted manure to improve the soil quality.

Another important aspect of soil is its texture.

Peruvian lilies prefer soil that is loose and crumbly, which allows for good airflow and drainage. If your soil is too compacted or heavy, you can amend it with sand, perlite, or vermiculite to improve its texture.

Fertilizer provides the necessary nutrients for your Peruvian lilies to grow strong and healthy. A slow-release fertilizer applied every few months will help keep the plant well-nourished.

Be sure to choose a fertilizer that is high in phosphorus, which promotes blooming.

When applying fertilizer, follow the package instructions and be careful not to over-fertilize.

Over-fertilizing can lead to burnt roots and leaves, as well as other plant stress. Additionally, avoid fertilizing during the winter months when the plant is dormant.

Peruvian lilies generally need to be repotted every 2-3 years, or when the plant becomes root-bound. Signs of a root-bound plant include slow growth, yellowing leaves, and roots that are growing out of the drainage holes at the bottom of the pot.

To repot your Peruvian lily, choose a pot that is one size larger than the current pot and fill it with fresh potting soil. When repotting, gently loosen the roots and remove any dead or damaged roots.

Place the plant in the new pot and fill in the gaps with soil, making sure not to cover the base of the plant's stem. Water the plant thoroughly and place it in a bright, indirect light for a few days to allow it to acclimate to its new surroundings.


Peruvian lilies can be propagated through division or from seed. Division is the easiest method and should be done in the spring or fall when the plant is not actively blooming. Gently remove the plant from its pot and separate the roots into smaller sections.

Each section should have at least three stems and a healthy root system. Plant each section in its own pot and water thoroughly. Peruvian lilies can also be propagated from seed, but this method is more challenging.

Collect the seeds from the plant and sow them in a well-draining soil mix. Cover the seeds lightly with soil and water. Keep the soil moist and place the pot in a warm, bright location. Germination can take several weeks to several months.

Pruning is an important part of Peruvian lily care, as it promotes new growth and helps maintain the plant's shape.

In the spring, when new growth appears, prune back any dead or damaged stems and remove any spent flowers. This will encourage the plant to produce more blooms and prevent it from becoming too leggy.

In addition to spring pruning, you can also prune your Peruvian lily throughout the growing season to keep it in shape. However, avoid pruning too heavily, as this can stress the plant and reduce its blooming potential.

Troubleshooting Peruvian Lily Problems

Growing Problems

Peruvian lilies can be prone to fungal diseases such as gray mold and root rot. To prevent these diseases, make sure the soil is well-draining and do not overwater.

If you notice any signs of disease, such as yellowing leaves or black spots, remove the affected leaves and treat the plant with a fungicide.

You can also prevent disease by spacing your plants properly to promote good air circulation.
