The Alocasia Purple Sword thrives in bright, indirect light. It should be placed near a window where it can receive filtered sunlight. Avoid placing it in direct sunlight, as this can scorch the leaves.


Proper watering is crucial for the health of the Alocasia Purple Sword. Keep the soil consistently moist, but be careful not to overwater it. Ensure that the soil has good drainage to prevent waterlogging, which can lead to root rot.


Being native to rainforests, the Alocasia Purple Sword loves high humidity. You can increase humidity levels by misting the leaves regularly or placing the plant on a tray filled with water and pebbles. Alternatively, you can use a humidifier near the plant.


The Alocasia Purple Sword prefers warm temperatures ranging from 65°F to 85°F (18°C to 29°C). It should be protected from cold drafts and temperature extremes.


Use a well-draining potting mix that retains moisture without becoming waterlogged. A mix of peat moss, perlite, and orchid bark works well for the Alocasia Purple Sword.


During the growing season (spring and summer), feed the plant with a balanced liquid fertilizer every two weeks. Dilute the fertilizer to half the recommended strength to avoid over-fertilization.

Propagation Guide


The Alocasia Purple Sword can be propagated through division. This method involves separating the rhizomes of the plant to create new individual plants. Follow these steps to successfully propagate through division:

  1. Repotting: When repotting the plant, carefully remove it from its current container and gently shake off the excess soil. This will expose the rhizomes, which are the underground stems of the plant.
  2. Separation: Examine the rhizomes and identify natural separations or sections that can be divided into individual plants. It’s crucial to ensure that each division has some roots attached to it. Use a clean and sharp knife or shears to carefully separate the rhizomes.
  3. Planting: Once you have divided the rhizomes, prepare separate pots for each division. Choose pots that are large enough to accommodate the root system and allow for future growth. Fill the pots with a well-draining potting mix.
  4. Care: Place each division in its own pot and gently press the soil around the roots to secure the plant. Water the divisions thoroughly, ensuring that the soil is evenly moist. Provide them with the same care as the parent plant, including adequate sunlight, humidity, and regular watering.

Additional Tips

  • It’s recommended to propagate the Alocasia Purple Sword during the plant’s active growth period, which is usually in the spring or summer.
  • Ensure that the divisions are not overcrowded in their new pots, as this can hinder their growth and development.
  • Monitor the moisture levels of the soil, ensuring it’s not too dry or waterlogged. Proper watering is essential for the successful establishment of the divisions.
  • Regularly check for signs of pests or diseases and take appropriate measures to prevent or treat them.

By following these propagation techniques and providing the necessary care, you can expand your collection of Alocasia Purple Sword plants and enjoy their beauty in multiple pots throughout your home or garden.

Pruning Guide

Pruning is generally not required for the Alocasia Purple Sword. However, if you wish to maintain the plant’s appearance, you can follow these steps:

Removing Dead or Damaged Leaves

Inspect the plant regularly and remove any dead or damaged leaves. This helps maintain the overall health and aesthetics of the plant.

Tools for Pruning

Use clean and sharp pruning shears to minimize damage to the plant. Make sure to clean the tools before and after use to prevent the spread of diseases or pests.

Pruning Technique

When pruning, make clean cuts just above the node or stem junction. Avoid cutting too close to the main stem, as this may cause unnecessary stress to the plant.

Remember, while pruning can be beneficial for the plant, it is not always necessary for the Alocasia Purple Sword. Assess the plant’s needs and prune selectively to maintain its overall well-being.

Repotting Guide

Frequency of Repotting

As the Alocasia Purple Sword grows, it may outgrow its current pot. Repotting is recommended every one to two years, preferably in the spring when the plant is entering its active growth phase.

Pot Selection

Choose a slightly larger pot that provides enough room for the plant’s root system to expand. Ensure that the pot has drainage holes to prevent waterlogging, which can lead to root rot.

Soil Preparation

Prepare fresh potting soil suitable for Alocasia Purple Sword. It is recommended to use a well-draining mix that retains moisture while allowing excess water to escape. A mix of peat moss, perlite, and orchid bark works well for these plants.

Repotting Process

  1. Gently remove the plant from its current pot, taking care not to damage the roots.
  2. Inspect the roots for any signs of rot or disease. Trim off any damaged or unhealthy roots using clean, sterilized pruning shears.
  3. Place a layer of fresh potting soil at the bottom of the new pot.
  4. Position the Alocasia Purple Sword in the center of the pot, ensuring that the root ball sits at the same level as it did in the previous pot.
  5. Fill the remaining space around the plant with fresh potting soil, gently firming it down to provide stability.
  6. Water the plant thoroughly, allowing excess water to drain out of the pot.


After repotting, place the Alocasia Purple Sword in a bright, indirect light location. Avoid direct sunlight, as it can scorch the leaves. Keep the soil consistently moist, but not waterlogged, and monitor the plant for any signs of stress or dehydration.

Remember, repotting provides the Alocasia Purple Sword with the necessary space and nutrients to continue thriving. Following these guidelines will ensure a successful and healthy repotting process.
