Introducing the Autograph Tree

The Autograph Tree, scientifically known as Clusia rosea, is a striking evergreen plant that is native to the tropical regions of the Americas. Known for its glossy, dark green leaves, the Autograph Tree gets its name from its thick leaves which you can carve your name into.

Its popularity as a houseplant has soared in recent years so these are becoming easier to find across the world. While the Autograph Tree is durable and relatively low-maintenance, it does require specific care to thrive (which we will cover below).

Distinctive Features

One of the most distinguishing features of the Autograph Tree is its leaves. Thick and leathery, their texture is perfect for etching names or messages – hence the plant’s unique common name. It’s worth noting, however, that excessive ‘autographing’ can damage the plant, so it’s not something we actually recommend doing.

Size and Growth

As a houseplant, the Autograph Tree typically reaches a height of 1 metre maximum. However, in its natural habitat, it can grow several metres tall. Despite its potential size, this plant is relatively slow-growing, adding just a few new leaves each year so patience is important.

Flowering and Fragrance

The Autograph Tree produces beautiful, star-shaped flowers that typically bloom in the summer months. These white blossoms have a pleasant, subtle fragrance and will often attract bees and butterflies if the plant is kept outdoors.

There are several varieties of Autograph Trees available, each with its own unique characteristics. The most popular is the Clusia rosea ‘Variegata’, known for its stunning variegated foliage. However, others prefer the Clusia rosea ‘Nana’, a dwarf variety that is perfect for smaller spaces.

Autograph Tree Lighting Requirements

The Autograph Tree thrives in bright, indirect sunlight but it can tolerate less light, making it a versatile and adaptable houseplant. However, too much direct sunlight can cause the leaves to scorch and drop.

Artificial Lighting:

Autograph Trees can also flourish under fluorescent light. This makes it an ideal choice for office environments or areas in your home without natural light.

Note: Despite being a low-light tolerant plant, your Autograph Tree will grow more slowly in these conditions. It’s important to monitor your plant’s health and adjust its location if needed.

Lighting Changes Across Seasons

Remember, the intensity of sunlight changes with the seasons. During the brighter summer months, you may need to move your Autograph Tree further away from the window to avoid sunburn.

Signs of Incorrect Lighting:

  • Leaf Scorch: This is often a sign of too much direct sunlight. The leaves may become brown and crispy.
  • Leggy Growth: If your plant is stretching towards the light and the space between leaves is increasing, it may not be getting enough light.

Watering an Autograph Tree: When, How and How Much

When to Water your Autograph Tree

Watering frequency for the Autograph Tree depends on the season and the plant’s living conditions. During the growing season (spring and summer), the plant requires more frequent watering (roughly once a week). In autumn and winter, the plant enters a dormant phase, needing less water (roughly every two weeks).

How to Water your Autograph Tree

To water your Autograph Tree, begin by thoroughly soaking the soil until water starts to drain from the bottom. This method ensures every part of the root system gets adequate moisture. Nevertheless, avoid water stagnation in the saucer as it can lead to root rot.

How Much Water to Give your Autograph Tree

The amount of water your Autograph Tree needs depends on its size and the pot’s size. As a rule of thumb, water until it begins to drain from the bottom. Then after 15 minutes, remove any excess water that is still at the bottom of the pot or saucer to avoid overwatering your plant.

Temperature Requirements of an Autograph Tree

Daytime Temperatures: The Autograph Tree flourishes in temperatures ranging from 32-86°F (20-30°C) during the day. As a tropical plant, it is used to warmer climates and thrives in these conditions.

Night-time Temperatures: At night, the temperature should ideally be a little cooler but not below 61°F (16°C). Sudden and prolonged temperature drops below this can be harmful to the plant.

If you live in a colder climate, consider keeping your Autograph Tree indoors or in a greenhouse where the temperature can be regulated. If the temperature falls below the recommended range, the leaves may become discoloured or even fall off. We highly recommend investing in a thermometer to keep track of any temperature changes.

Humidity Needs of an Autograph Tree

Known for its tropical origins, the Autograph Tree likes a humid environment. Aim for between 45-65% humidity as anything above this for long periods of time can cause the leaves to rot.

Maintaining Optimal Humidity

  • Regularly mist your Autograph Tree, especially during drier months.
  • Consider placing a humidifier nearby or grouping it with other plants to increase humidity.
  • Placing your plant on a tray of pebbles filled with water can also enhance humidity levels.

Humidity Issues

Curled or brown leaf tips or small yellow/brown spots on the leaves can indicate a humidity problem. If you notice these signs, check the humidity level around your plant and adjust your plant’s environment accordingly and monitor any changes.

Fertilizing the Autograph Tree

Although it doesn’t require extensive fertilising, a bit of nutritional boost can certainly aid in its overall growth and development. Proper fertilisation can help maintain the tree’s vigorous growth and vibrant green foliage.

When to fertilise: The only time you should be fertilizing an Autograph Tree is during its active growth period which usually falls between spring and early autumn. During the dormant winter months, you should stop fertilizing.

What to use: A balanced, slow-release fertiliser with an NPK ratio of 10-10-10 is generally recommended.

Steps for Fertilising the Autograph Tree

  1. Step 1: Before applying the fertiliser, ensure the soil is damp. This helps the roots to absorb the nutrients effectively.
  2. Step 2: Spread the fertiliser evenly around the base of the tree, keeping it a few inches away from the stem to prevent root burn.
  3. Step 3: After applying the fertiliser at slightly less than the recommended strength, water the plant thoroughly to help distribute the nutrients throughout the soil.

Choosing the Right Pot and Soil

Pot Selection

When choosing a pot, consider one that is approximately 2-3 inches larger in diameter than the root ball of your Autograph Tree.

The pot should also have several drainage holes to prevent water accumulation, which can cause root rot. Terracotta pots are a popular choice due to their porous nature and excellent drainage capabilities but the downside is that they are breakable.

Soil Selection

Autograph Trees thrive in well-draining, fertile soil. A high-quality, peat-based potting mix is generally a good choice. Alternatively, you can create your own mix by combining equal parts peat moss, sharp sand, and loamy garden soil.

Note: Autograph Trees prefer slightly acidic to neutral pH levels, so if you are having issues with your plant and you can’t seem to diagnose the problem, it’s best to test your soil’s pH and amend it if necessary.

Repotting an Autograph Tree: A step-by-step guide

What you’ll need:

  • A new pot that is 2 inches larger in diameter than the current one
  • High-quality potting soil, preferably one designed for tropical plants
  • Gardening gloves
  • A gardening trowel


  1. Preparation: Begin by moistening the potting soil in a separate container. It should be damp, but not waterlogged. Put on your gardening gloves to protect your hands.
  2. Removing the tree: Carefully take the Autograph Tree out of its current pot. Loosen the root ball using your fingers, with a gentle touch to reduce the risk of damage. Don’t worry too much if you damage the odd root as your plant will recover quickly.
  3. Placement: Place a layer of the damp soil at the bottom of the new pot. Position your Autograph Tree in the centre of the pot.
  4. Replanting: Add the remaining soil around the tree, pressing down gently to remove any air pockets. The soil surface should be at the same level it was in the previous pot.
  5. Post-repotting care: Water the plant thoroughly after repotting and place it in a spot with indirect light. Refrain from fertilising for about a month to allow the tree to recover.

Pruning the Autograph Tree

Pruning your Autograph tree is a vital aspect of its overall care but it is so often forgotten (or shied away from). When done correctly, it can enhance the health and aesthetic appeal of your plant so should be something you are putting into your care routine.

When to Prune

The best time to prune your Autograph tree is during the early spring or summer months. This is the plant’s active growing period, and it can recover more swiftly from any stress related to pruning.

Tools Required

For the pruning process, you would need a pair of clean, sharp pruning shears or scissors. It’s crucial to ensure that your tools are clean to prevent the spread of any plant diseases.

Pruning Procedure

While pruning, your goal should be to maintain the shape of the plant and to remove any dead or diseased branches. Here’s a simple, step-by-step guide:

  1. Identify the branches that need to be pruned. These can be dead, diseased or simply overgrowing branches that you want to remove to reshape your plant.
  2. Using your shears, make a cut at a 45-degree angle about 1/4 inch above a leaf node. This encourages new growth.
  3. Make sure not to prune more than one-third of the plant at a time as this can stress the plant.

Post Pruning Care

After pruning, ensure to give your Autograph tree some additional TLC. Water it thoroughly and consider applying a balanced, water-soluble fertiliser to support its recovery and new growth.

Flowers on an Autograph Tree

The tree produces blooms that have a colour palette ranging from pale pink to deep, rosy hues, making them a beautiful contrast against the dark green leaves. This will happen a lot more frequently when the plant is grown outdoors so don’t expect any on your houseplant.

Flowering Cycle

Autograph Trees typically bloom in the warmer months, with the flowering season extending from late spring to early autumn.

Care for the Blooms

To ensure a hearty and healthy flowering, certain care practices should be followed. These include providing ample sunlight, maintaining a warm temperature, and regular watering.

  1. Sunlight: Autograph Trees thrive in bright, indirect light. Make sure your tree is placed near a window where it can receive plentiful light, but shielded from direct, harsh sunlight.
  2. Temperature: These trees prefer warm conditions, similar to their native tropical habitat. Aim for temperatures between 60-85°F (15-29°C) for optimal growth.
  3. Water: Water generously during the flowering season, ensuring the soil is moist but not waterlogged.

Autograph Tree Toxicity to Pets and Humans

Toxicity to Humans

The Autograph Tree is toxic to humans when ingested and can cause gastrointestinal upset. It’s always a good idea to keep the plant out of reach of curious children who may be tempted to taste its interesting leaves.

Toxicity to Pets

All parts of the Autograph Tree are toxic to pets if ingested. Symptoms can include vomiting, loss of appetite, and depression.

What to do in case of ingestion

  • If a human has ingested parts of the plant, monitor them for any signs of discomfort. Although unlikely, if severe symptoms occur, contact a medical professional immediately.
  • In the case of pets, it’s advisable to contact your vet promptly if you suspect your pet has ingested any part of the Autograph Tree.

How to Clean an Autograph Tree

Keeping your Autograph Tree in tip-top condition means more than just watering and feeding it – regular cleaning is key to maintaining its health. Here are some simple steps you can follow to clean your Autograph Tree:

  1. Prepare Your Tools: Gather a soft, clean cloth or sponge, a bowl of lukewarm water, and a mild soap. It’s important not to use harsh cleaning agents as they can damage the natural coating on leaves which can leave them dull and damaged.
  2. Wipe the Leaves: Gently wipe each leaf and be sure to clean the underside as well, as this is where pests often hide.
  3. Rinse and Dry: Once all the leaves are clean, wip them with a bit of clean lukewarm water and dry gently to prevent water spots or leaf rot from forming.

Remember, cleaning your Autograph Tree isn’t just about aesthetics. A clean plant is less likely to fall prey to pests and diseases. Plus, clean leaves can photosynthesise more efficiently as even a thin layer of dust can block quite a lot of sunlight, enabling your plant to grow stronger and healthier.

Managing Pests and Diseases

Common Pests

Autograph Trees may attract a variety of pests, including mealybugs, spider mites, and aphids. These pests can cause discolouration (small brown or yellow spots), leaf curling, and overall decreased plant vitality (your plant will start to look a little limp and sad).

Control Measures

When dealing with pests, begin by spraying your plant with a mild, soapy water solution. If the infestation persists, you may need to use an insecticidal soap or a neem oil spray. Always follow the manufacturer’s instructions when using these products and make sure to isolate your infected plant to stop the spread to other houseplants.

Common Diseases

Overwatering your Autograph Tree can lead to root rot, a serious disease. Signs of root rot include yellowing leaves and a soggy, dark base. If you suspect root rot, you may need to repot your plant into fresh, well-draining soil. Never wait for the soil to naturally dry out on its own if it is waterlogged as this just risks more damage.
