The Suitable Environment for Alstroemeria

Alstroemeria, also known as Peruvian lilies or Lily of the Incas, thrives in specific environmental conditions that closely mimic their native habitat. To successfully grow alstroemeria from cuttings, it’s essential to recreate these conditions as closely as possible.

Temperature: Alstroemeria prefers a moderate temperature range, ideally between 50-80°F (10-27°C). Extreme temperatures, either too hot or too cold, can hinder the growth and blooming process.

Sunlight: These plants enjoy full sunlight exposure but can also tolerate partial shade. Aim for providing a minimum of 6 hours of direct sunlight or bright indirect light daily to support healthy growth.

Soil: Alstroemeria needs well-draining, fertile soil to grow properly. Incorporate organic matter, such as compost or peat moss, to create loamy soil, which promotes aeration and prevents waterlogged roots. The ideal soil pH is between 6.0 and 6.5, slightly acidic.

Water: Consistent watering is essential for alstroemeria, as they cannot tolerate drying out. Keep the soil evenly moist, but be cautious about overwatering, as this can lead to root rot. It is best to water deeply during periods of high moisture demand, such as during bud formation or when flowering.

Mulching: Spread a layer of organic mulch, like bark chips or straw, around the base of your alstroemeria plants. This helps to retain soil moisture, suppress weeds, and regulate soil temperature. Avoid applying mulch too closely to the plant’s stem, as this can cause dampness and promote rot.

By providing the right environment for your alstroemeria cuttings, you can increase their chances of successful growth and enjoy beautiful blooms in your garden for years to come. Keep in mind that these plants may need additional support, such as stakes or cages, to encourage strong, upright growth and prevent them from falling over as they mature.

Choosing the Cuttings

When selecting cuttings for alstroemeria growth, it’s essential to choose healthy, disease-free stems. Look for stems with at least two growth nodes, as this will ensure a higher likelihood of successful root development. Avoid choosing cuttings with signs of pests or damage, as these can hinder the growth process.

The ideal time to take cuttings is during the early morning when the plant is well-hydrated and full of energy. It’s best to choose cuttings that are actively growing but not yet flowering, as this will allow the plant’s energy to be focused on establishing roots instead of creating blooms.

When cutting the alstroemeria, use a clean and sharp pair of scissors or pruning shears to make a clean cut at a 45-degree angle, about 4 to 6 inches below the growth node. This angled cut will facilitate better water intake and maximize the surface area for root formation. Immediately place the cuttings in a container with clean water to prevent dehydration.

Before planting the cuttings, it’s important to prepare them well to increase their chances of taking root. Remove any leaves from the lower part of the stem, leaving only a couple of healthy leaves at the top. This will minimize water evaporation and help the plant devote its resources to root growth. Additionally, applying a good quality rooting hormone to the cut end of the cutting can stimulate faster root development and increase survival rates.

By carefully choosing and preparing the cuttings, as well as providing them with a suitable environment and proper care, your alstroemeria plants will thrive and produce beautiful blooms for years to come.

Preparing the Cuttings


Start by selecting healthy alstroemeria stems to ensure the success of your cuttings. They should show no signs of disease or damage. Gently wash the entire stem with lukewarm water to remove dirt or any potential pathogens. It is essential to clean the stems thoroughly to minimize the risk of infection during the propagation process.


To prepare the alstroemeria cuttings, use a sharp, sterilized pair of pruning shears or scissors. Carefully make a cut at a 45-degree angle, about 4-6 inches from the top of the stem. Ideally, each cutting should have at least two or three nodes, as this is where new roots will form. Remove any leaves or flowers from the lower part of the cutting, but leave a few leaves on the top to promote photosynthesis and growth.

Rooting Hormone Application

Applying rooting hormone can increase the chances of successful growth for your alstroemeria cuttings. Choose a suitable rooting hormone, available in liquid, powder, or gel form. Gently dip the cut end of the cutting into the hormone, making sure to fully coat the lower node. Tap off any excess hormone to prevent overexposure. Following the hormone application, plant your alstroemeria cutting in a well-draining potting medium, such as perlite or vermiculite, and maintain a consistently moist environment for the cutting to develop roots.

Proper Planting Technique

Growing alstroemeria from cuttings requires a proper planting technique to ensure successful growth and a healthy plant. Before planting, choose a location with well-drained soil and partial to full sun exposure, as alstroemerias thrive in these conditions.

First, prepare the cuttings by trimming the stem to around 4-6 inches in length, ensuring to make the cuts below a pair of leaves. Carefully remove the lower leaves of the cutting, leaving only the top few pairs. Dipping the cut end of the alstroemeria cutting into a rooting hormone powder can increase the likelihood of successful root growth, but it’s not strictly required.

Create a planting mix with a combination of equal parts peat moss, perlite, and vermiculite to achieve optimal aeration and moisture retention. Fill a small pot or container with the prepared mixture, ensuring it has drainage holes in the bottom.

Next, gently create a small hole in the center of the planting mix using a pencil or similar tool, and place the cutting into the hole, burying the cut end of the stem and the bottom leaf nodes beneath the soil. Firmly press the planting mix around the cutting to provide support and remove any air pockets.

Water the newly planted alstroemeria cutting thoroughly, ensuring the planting mix is evenly moist but not overly saturated. To maintain humidity levels essential for successful rooting, place a transparent plastic bag or plastic wrap over the pot, creating a mini greenhouse effect. Be sure to provide the cutting with proper ventilation by opening the plastic covering every few days to prevent mold and pathogens from developing.

Place the potted cutting in a location with bright indirect light, keeping the temperature consistently between 65-75°F (18-24°C). Monitor the cutting for new growth, and once new leaves and shoots are evident, the cutting has rooted successfully. You may then transplant the alstroemeria into the ground or in a larger container for continued growth and development.

Care After Planting


It is crucial to maintain consistent moisture levels in the soil after planting alstroemeria cuttings. Water the cuttings regularly, about once or twice per week, depending on weather conditions. Be careful not to over-water, as this can lead to root rot. In addition, it’s important to use a well-draining soil mixture when planting, which allows excess water to drain away while still retaining enough moisture for the plants.


Providing proper nutrients will encourage your alstroemeria cuttings to grow strong and healthy. Choose a balanced fertilizer, preferably something with a 10-10-10 or 14-14-14 formula. You should begin fertilizing about 2-3 weeks after planting. Apply the fertilizer once per month during the active growing season. Always follow the manufacturer’s instructions for the best results. Remember not to over-fertilize, as this may damage the plants.


Regular pruning practices are essential for maintaining the growth and appearance of alstroemeria. As the flowers begin to fade, it is a good idea to remove them to promote continuous blooming. This process is known as deadheading. Gently remove the spent blooms with your hands or use a pair of clean, sharp pruning shears.

In addition to deadheading, it’s important to prune the plants to remove dead, damaged, or diseased foliage. Doing so will maintain the overall health of the plant and encourage more vigorous growth. Be sure to sanitize your pruning tools before and after each use to prevent the spread of diseases.

By following the above guidelines on watering, fertilizing, and pruning, your alstroemeria cuttings should grow successfully and provide you with beautiful, vibrant blooms throughout the growing season.
