Growing Aeonium arboreum Indoors: Expert Care Tips & Tricks

Quick Care Summary

To care for Aeonium arboreum, place it in a spot with bright, indirect light, such as 3 feet from an east- or west-facing window, providing 200-400 foot-candles of light. Water your Aeonium arboreum every 7-10 days in the summer and every 14 days in the winter, making sure the soil is dry to the touch between waterings. Keep the temperature between 65-80°F (18-27°C) and maintain a medium humidity level, around 50-60%. With proper care, Aeonium arboreum is relatively easy to care for and can thrive indoors. According to a 1989 NASA Clean Air Study, Aeonium arboreum is effective at reducing air pollutants, such as formaldehyde, in enclosed spaces.

Overview

Aeonium arboreum, also known as Tree Aeonium, is a succulent species native to the Canary Islands. It's known for its striking, fleshy leaves that grow in a compact, tree-like shape, making it a popular choice for indoor gardens. The scientific name, Aeonium arboreum, refers to the plant's tree-like appearance, with "Aeonium" meaning "age" or "long-lived" and "arboreum" meaning "tree-like". This plant has become a staple in many indoor gardens due to its unique appearance and low-maintenance requirements.

Aeonium arboreum is a relatively small plant, growing up to 3 feet tall, with thick, fleshy leaves that are a deep green color. The leaves are arranged in a rosette pattern, giving the plant a compact, tree-like shape. The plant produces small, white flowers in the summer months, which are relatively inconspicuous but still add to the plant's beauty.

Pros and Cons

Pros:

• Aeonium arboreum is a low-maintenance plant that can thrive in indoor conditions with minimal care.
• It's an excellent air-purifying plant, making it a great choice for indoor spaces.
• The plant's unique, tree-like shape makes it a stunning addition to any room.
• Aeonium arboreum is relatively small, making it perfect for small spaces or apartments.
• It's a great choice for beginners, as it's relatively easy to care for and can tolerate some neglect.

Cons:

• Aeonium arboreum can be sensitive to overwatering, which can lead to root rot and other problems.
• The plant may drop its leaves if it's not receiving enough light or water.
• Aeonium arboreum can be prone to pests, such as mealybugs and spider mites, if not properly cared for.

Light: Finding the Perfect Spot for Aeonium arboreum

Aeonium arboreum prefers bright, indirect light, but can tolerate some direct sunlight. The ideal light range for Aeonium arboreum is 200-400 foot-candles, which is equivalent to placing the plant 3 feet from an east- or west-facing window. In the Northern Hemisphere, a south-facing window may be too intense, especially during the summer months, and may cause the leaves to become scorched or bleached.

In the winter months, when the sun is lower in the sky, Aeonium arboreum may require more light to photosynthesize. To compensate for the reduced light, you can move the plant closer to the window or use grow lights to supplement the natural light.

Factor	Requirement	Pro Tip
Light	200-400 foot-candles	Place the plant 3 feet from an east- or west-facing window
Water	every 7-10 days	Check the soil moisture by sticking your finger into the soil up to the first knuckle
Humidity	50-60%	Use a pebble tray or humidifier to maintain the ideal humidity level
Temperature	65-80°F (18-27°C)	Avoid placing the plant near heating vents or drafty windows
Soil	60% potting mix + 30% perlite + 10% orchid bark	Use a well-draining potting mix to prevent root rot
Fertilizer	Balanced 10-10-10, monthly spring-summer	Dilute the fertilizer to half strength to prevent burning the roots
Toxicity	non-toxic to cats and dogs	According to the ASPCA, Aeonium arboreum is non-toxic to cats and dogs

Watering: The Key to Healthy Roots

Aeonium arboreum prefers dry soil, so it's essential to avoid overwatering. To check the soil moisture, stick your finger into the soil up to the first knuckle. If the soil feels dry, it's time to water. Water the plant every 7-10 days in the summer and every 14 days in the winter, making sure the soil is dry to the touch between waterings.

Use room-temperature water, and avoid getting water on the leaves to prevent rot. If you notice the leaves becoming soft and mushy, it may be a sign of overwatering. To recover from overwatering, stop watering the plant for a few weeks and allow the soil to dry out completely.

Soil & Repotting: Giving Aeonium arboreum Room to Grow

Aeonium arboreum prefers a well-draining potting mix, such as a mix of 60% potting mix, 30% perlite, and 10% orchid bark. This mix will help prevent root rot and ensure the plant's roots have enough oxygen.

Repotting Aeonium arboreum is necessary every 2-3 years, as the plant outgrows its container. To repot, follow these steps:

1. Choose a container that is only 1-2 sizes larger than the current one.
2. Gently remove the plant from its pot, taking care not to damage the roots.
3. Inspect the roots and trim any dead or damaged roots.
4. Place the plant in the new container, adding fresh potting mix around the roots.
5. Water the plant thoroughly after repotting.

Fertilizing: Feeding Aeonium arboreum for Optimal Growth

Aeonium arboreum requires fertilization during the growing season, which is from spring to summer. Use a balanced fertilizer, such as 10-10-10, and dilute it to half strength to prevent burning the roots. Fertilize the plant monthly during the growing season, and skip fertilization during the winter months when the plant is dormant.

Humidity and Temperature: Creating the Perfect Environment

Aeonium arboreum prefers a medium humidity level, around 50-60%. To maintain the ideal humidity level, you can use a pebble tray or humidifier. Place the plant on a tray filled with water and pebbles, or use a humidifier to add moisture to the air.

The ideal temperature range for Aeonium arboreum is 65-80°F (18-27°C). Avoid placing the plant near heating vents or drafty windows, as this can cause the temperature to fluctuate.

Toxicity & Safety: Keeping Your Pets Safe

According to the ASPCA, Aeonium arboreum is non-toxic to cats and dogs. However, it's still possible for your pet to experience gastrointestinal upset if they ingest a large amount of the plant.

If you suspect your pet has ingested Aeonium arboreum, contact the ASPCA Animal Poison Control Center at (888) 426-4435 for advice.

Common Problems

Symptom	Most Likely Cause	Quick Fix	Prevention
Soft, mushy stem base	Overwatering	Stop watering for a few weeks	Check soil moisture regularly
Yellowing leaves	Underwatering	Water the plant thoroughly	Water the plant regularly
Pests on the leaves	Infestation	Treat with insecticidal soap	Inspect the plant regularly
Scorched leaves	Too much direct sunlight	Move the plant to a shadier location	Use a sheer curtain to filter the sunlight
Slow growth	Lack of nutrients	Fertilize the plant monthly	Use a balanced fertilizer

Overwatering

Overwatering is a common problem with Aeonium arboreum. To fix this, stop watering the plant for a few weeks and allow the soil to dry out completely. Check the soil moisture regularly to prevent overwatering in the future.

Underwatering

Underwatering can also be a problem, especially during the summer months when the plant is actively growing. To fix this, water the plant thoroughly and make sure the soil is moist but not waterlogged.

Pests

Pests, such as mealybugs and spider mites, can infest Aeonium arboreum. To fix this, treat the plant with insecticidal soap and inspect the plant regularly to prevent future infestations.

Where to Buy & What to Look For: Finding the Perfect Specimen

Aeonium arboreum is widely available at nurseries and online plant retailers. When purchasing a plant, look for the following signs of a healthy specimen:

• Firm, fleshy leaves
• A compact, tree-like shape
• No signs of pests or diseases
• A well-draining potting mix

Avoid plants with soft, mushy stems or leaves, as this can be a sign of overwatering or root rot.

Propagation: Creating New Plants

Aeonium arboreum can be propagated using leaf cuttings or division. To propagate using leaf cuttings, follow these steps:

1. Choose a healthy leaf and cut it from the plant using a sharp knife or pair of scissors.
2. Allow the cut end to dry for a few days to form a callus.
3. Plant the leaf cutting in a well-draining potting mix, such as a mix of 60% potting mix and 40% perlite.
4. Water the soil gently but thoroughly.
5. Place the plant in a bright, indirectly lit location and maintain a temperature of 65-75°F (18-24°C).
