The variegated Monstera adansonii, commonly known as the Swiss Cheese Plant, is a stunning and unique houseplant cherished for its striking foliage. This plant is a variegated form of the standard Monstera adansonii, featuring leaves that exhibit a beautiful mix of green and creamy white or yellow patterns. The variegation can vary greatly from leaf to leaf, with some leaves having large sections of white or yellow, while others may have speckles or marbling.

• Leaves: The leaves are perforated with natural holes, giving them a characteristic "Swiss cheese" appearance. The variegation adds to the aesthetic appeal, with contrasting colours making each leaf a unique piece of art.
• Size: When grown indoors, the plant can reach up to 1.2-1.8 meters (4-6 feet) in height if given proper support to climb.
• Growth Habit: Monstera adansonii is a climbing plant, using aerial roots to attach itself to supports like moss poles or trellises.

Care Guide

Light

• Optimal Conditions: Variegated Monstera adansonii thrives in bright, indirect light. Too much direct sunlight can scorch the leaves, especially the variegated parts, which are more sensitive.
• Variegation Maintenance: To maintain the variegation, ensure the plant receives plenty of bright light. In low light conditions, the plant may revert to producing more green leaves, losing some of its variegation.

Watering

• Watering Schedule: Water when the top 2-3 cm (1 inch) of the soil is dry. Overwatering can lead to root rot, while underwatering can cause the leaves to wilt and turn brown.
• Humidity: This plant enjoys high humidity levels. Regular misting or using a humidifier can help keep the leaves healthy, especially in drier indoor environments.

Soil

• Type: Use a well-draining, airy soil mix. A mix designed for aroids, which typically includes components like peat moss, perlite, and orchid bark, is ideal.
• pH Level: The soil should be slightly acidic to neutral, with a pH range of 5.5 to 7.0.

Temperature

• Optimal Range: Keep the plant in a warm environment with temperatures between 18-27°C (65-80°F). Avoid cold drafts and sudden temperature changes.

Fertilising

• Frequency: Feed the plant with a balanced, water-soluble fertiliser every 4-6 weeks during the growing season (spring and summer). Reduce feeding in autumn and winter when the plant's growth slows down.
• Type: Use a fertiliser with a balanced NPK ratio (e.g., 10-10-10) or one specifically formulated for houseplants.

Pruning and Maintenance

• Pruning: Regularly prune to control its size and shape. Remove any dead or yellowing leaves to encourage new growth.
• Support: Provide a support structure such as a moss pole or trellis to encourage climbing. The aerial roots will attach themselves to the support, mimicking their natural growth habit.

Propagation

• Method: Propagate through stem cuttings. Cut a section of the stem that includes at least one node and a leaf. Place the cutting in water or moist soil until roots develop, then transplant it into a pot with a well-draining soil mix.

Pests and Diseases

• Common Pests: Watch out for spider mites, mealybugs, and aphids. Regularly inspect the leaves and treat infestations promptly with insecticidal soap or neem oil.
• Diseases: Root rot is a common issue caused by overwatering. Ensure proper drainage and avoid letting the plant sit in water.

Repotting

• Frequency: Repot every 1-2 years or when the plant becomes root-bound. Choose a pot that is 2-5 cm (1-2 inches) larger in diameter than the current pot.
• Procedure: Carefully remove the plant from its pot, gently loosen the roots, and place it in a new pot with fresh soil. Water thoroughly after repotting.
