Welcome to my houseplant blog! In this post, I’ll share my expertise on Aloe dorotheae, commonly known as Sunset Aloe. This eye-catching succulent boasts vibrant green leaves with striking red-orange edges, making it a perfect addition to any indoor or outdoor garden. Not only is Sunset Aloe deer resistant and disease free, but it’s also relatively low-maintenance, making it an ideal choice for both experienced and novice gardeners.

How to Care for Aloe dorotheae

Light Requirements

Aloe dorotheae’s vibrant colors develop best in bright, indirect sunlight, making proper lighting crucial for this succulent. Place your plant near an east or west-facing window to ensure it receives 6-8 hours of indirect light daily. If natural light is insufficient, you can supplement it with a grow light placed 12-18 inches above the plant.

Outdoors, plant your Sunset Aloe in a location with morning sun and afternoon shade, as too much direct sunlight can cause leaf sunburn, a condition that manifests as brown or bleached patches on the leaves. To acclimate your plant to a new outdoor environment, gradually expose it to direct sunlight over the course of a week, increasing sun exposure by an hour each day to prevent sudden shock.

Watering Aloe dorotheae

Proper watering is essential for maintaining a healthy Aloe dorotheae. Overwatering is a common issue that can lead to root rot and even plant death. To avoid this, follow the “soak and dry” method. Water your succulent thoroughly, allowing the soil to become completely saturated. Then, wait until the soil dries out entirely before watering again.

During the summer months, you may need to water your Aloe dorotheae every 2-3 weeks, while in the cooler months, reduce the frequency to every 4-6 weeks. Keep in mind that factors such as pot size, soil type, and humidity can affect the plant’s water requirements. To check the soil’s moisture, insert a finger or moisture meter 1-2 inches into the soil. If it feels dry, it’s time to water your plant.


Use the “soak and dry” method to avoid overwatering. Water every 2-3 weeks in summer and every 4-6 weeks in cooler months. Check soil moisture before watering.

Soil Needs

Choosing the right soil for Aloe dorotheae is essential to prevent waterlogged roots and promote healthy growth. Well-draining soil is key. Commercially available cactus or succulent mixes work well, but you can also create your own blend. Combine equal parts of potting soil, perlite, and coarse sand, or use a mix of potting soil, pumice, and crushed lava rock.

Ensure that the pot you choose has drainage holes to allow excess water to escape. A terra cotta or unglazed ceramic pot can also help wick moisture away from the soil, reducing the risk of root rot. If your plant is in a container without drainage holes, consider adding a layer of pebbles or gravel at the bottom to improve drainage.

Temperature and Humidity

Sunset Aloe is adaptable to various temperatures but thrives in conditions between 55-80°F (13-27°C). To avoid temperature-related stress, keep your plant away from drafts, heating vents, or air conditioning units, as sudden temperature fluctuations can harm it. If you live in a region with freezing temperatures, bring your plant indoors during the winter months, as frost can damage or even kill Aloe dorotheae.

In terms of humidity, Aloe dorotheae can tolerate average indoor humidity levels. However, if you live in an arid environment or have an indoor heating system that dries out the air, consider placing a humidity tray near the plant or using a humidifier to maintain adequate moisture levels. Avoid misting your plant, as excess moisture on the leaves can lead to fungal infections or pest infestations.

How to Propagate Aloe dorotheae

Aloe Dorotheae


Aloe dorotheae offsets provide an efficient method for propagation. To ensure success, observe the following steps. First, choose a healthy, well-established offset that is at least one-third the size of the mother plant. Wearing gloves, carefully remove the offset by hand or with a sanitized, sharp tool like a knife or spade, severing the connecting root without damaging the main plant.

Once separated, let the offset dry in a shaded area for 1-3 days, allowing a callus to form over the cut surface, which helps protect against infections. Prepare a pot with well-draining soil mix and plant the offset, ensuring the base of the leaves is just above the soil level. Initially, water sparingly and gradually increase the frequency as roots develop, which can take several weeks.


Propagate Aloe dorotheae by gently removing healthy offsets, allowing them to dry and callus, then planting in well-draining soil. Increase watering frequency as roots develop.

Leaf Cuttings

Although less reliable, leaf cuttings can also propagate Aloe dorotheae. Select a firm, healthy leaf from the lower part of the parent plant. Using a sterile knife, cut the leaf at an angle close to the stem. Allow the leaf to dry in a shaded area for 3-5 days, enabling a protective callus to form over the cut end.

Fill a pot with moist, well-draining soil and insert the callused end approximately one inch deep. Place the pot in a bright location with indirect sunlight. Maintain soil moisture by misting regularly, avoiding overwatering. In 3-6 weeks, new roots and a small rosette should develop at the base of the cutting.


Propagation through leaf cuttings is less reliable. Cut a healthy leaf, let it dry and callus, then plant in moist soil. Mist regularly to maintain moisture.

Fertilizing Your Aloe dorotheae

While not a necessity, fertilizing Aloe dorotheae can promote healthy growth. Opt for a balanced, water-soluble fertilizer (such as a 10-10-10 or 20-20-20 formula) specifically formulated for cacti and succulents. Dilute the fertilizer to half strength to prevent nutrient burn.

Apply the fertilizer solution during the growing season, preferably in the spring and early summer months. Fertilizing once or twice a year is sufficient, as excessive nutrients can lead to leggy growth and reduced resistance to pests and diseases. Refrain from fertilizing during the plant’s winter dormancy.

Common Pests and Diseases

Aloe dorotheae is relatively hardy, but pests like mealybugs, aphids, and spider mites can infest the plant. To treat infestations, dab pests with a cotton swab soaked in rubbing alcohol or spray the plant with a solution of mild soap and water. Rinse the plant thoroughly after treatment to remove any soap residue.

Preventive measures include maintaining proper air circulation, ensuring adequate light, and avoiding overwatering. In addition, isolate new plants or those returning from outdoor locations for a couple of weeks to minimize the risk of introducing pests to your existing collection. Regularly inspect your plants for signs of pests or diseases, and address issues promptly to maintain overall plant health.
