Everything it needs
9 essentials at a glance
Watering
Aloe juvenna prefers to dry out between waterings.
Water thoroughly when the top 1-2 inches of soil feel dry, typically every 2-3 weeks in the growing season and less frequently in winter. Signs of over-watering include yellowing leaves and mushy stems, while under-watering may cause leaf shriveling and browning tips.
Light
This succulent thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, it should receive 6-8 hours of light daily. Too much direct sun can scorch the leaves, while insufficient light can lead to leggy growth.
Soil
A well-draining cactus or succulent mix is ideal, with a pH range of 6.0-7.0.
You can also create your own mix using equal parts potting soil, sand, and perlite to ensure proper drainage.
Humidity
Aloe juvenna prefers low humidity levels, typically around 30-50%.
To increase humidity, you can mist occasionally or place a humidity tray nearby. Signs of humidity stress include leaf curling or browning edges.
Temperature
This plant thrives in temperatures between 65-80°F (18-27°C) and can tolerate temperatures as low as 50°F (10°C).
It is best suited for USDA hardiness zones 9-11, as it cannot withstand frost.
Fertilizing
Use a balanced, diluted liquid fertilizer with an NPK ratio of 10-10-10 during the growing season, every 4-6 weeks.
In fall and winter, reduce feeding to once every 2-3 months. Signs of nutrient deficiency include slow growth and pale leaves.
Pruning
Prune Aloe juvenna as needed to remove dead or damaged leaves.
Use clean, sharp scissors or pruning shears to make clean cuts at the base of the leaf. Deadheading is not necessary, but removing spent leaves can improve appearance.
Repotting
Repot every 2-3 years or when the plant becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. To repot, gently remove the plant from its pot, shake off excess soil, and place it in fresh soil.
Propagation
Aloe juvenna can be propagated through offsets or leaf cuttings.
For offsets, gently remove the pups from the base of the plant and allow them to dry for a day before planting in well-draining soil. For leaf cuttings, let the cut end callous over for a few days before planting. The best time for propagation is during the spring or summer.

Care through the year
Spring
In spring, increase watering as the plant begins its active growth phase. Consider repotting if it has outgrown its container.
Summer
During summer, ensure the plant receives plenty of bright light and water every 2-3 weeks, allowing the soil to dry out between waterings.
Fall
In fall, gradually reduce watering as the plant prepares for dormancy. Monitor for any signs of pests.
Winter
In winter, reduce watering to once a month and keep the plant in a warm location, avoiding cold drafts.
