Monstera deliciosa ‘Borsigiana’ is a popular houseplant known for its attractive, fenestrated “Swiss cheese” leaves. Its manageable care makes it a favored choice, adding tropical vibrancy to homes.
Identifying Your Borsigiana
Distinguishing Monstera deliciosa ‘Borsigiana’ from the standard Monstera deliciosa involves observing specific growth characteristics. ‘Borsigiana’ exhibits a more vining habit with smaller leaves than the standard variety. While both develop fenestrations, ‘Borsigiana’ splits and holes are often smaller, less pronounced, and typically appear in a single row.
Another difference is internodal spacing, the distance between leaf nodes. ‘Borsigiana’ has longer internodal spaces, contributing to its faster growth. The petiole, the stalk connecting the leaf to the stem, of a mature Monstera deliciosa often has a crinkled texture, while the ‘Borsigiana’ petiole remains smooth.
Essential Care for Borsigiana
Light
Monstera deliciosa ‘Borsigiana’ thrives in bright, indirect light, mimicking its natural jungle habitat. Avoid direct sunlight, which can scorch leaves. An ideal placement is near an east-facing window for gentle morning light, or a west-facing window for several hours of indirect light. Supplemental grow lights can support healthy growth and fenestration development in low-light environments.
Watering
Proper watering is crucial; ‘Borsigiana’ prefers consistently moist, but not waterlogged, soil. Water when the top 1 to 2 inches of soil feel dry. Water thoroughly until excess drains from the pot, then empty any standing water to prevent root rot. Overwatering causes root damage, while underwatering leads to wilting and yellow leaves.
Soil and Potting
A well-draining, aerated, and nutrient-rich soil mix is optimal for ‘Borsigiana’ root health. A suitable blend includes potting soil amended with perlite, orchid bark, and peat moss or coco coir to enhance drainage and aeration. These components prevent compacted or waterlogged soil, which can suffocate roots. Repot every 2 to 3 years, or when root-bound, to provide fresh nutrients and space. Select a pot 1 to 2 inches larger in diameter with sufficient drainage holes.
Temperature and Humidity
As a tropical plant, ‘Borsigiana’ prefers warm, humid conditions. The ideal temperature range is 65°F (18°C) to 85°F (29°C). Temperatures below 60°F (16°C) slow growth, and frost must be avoided. Maintain humidity levels of 60% or higher, especially in dry indoor environments. Increase humidity using a humidifier, a pebble tray, or by grouping plants.
Fertilizing
During its active growing season (spring through summer), ‘Borsigiana’ benefits from regular fertilization. Use a balanced, liquid fertilizer diluted to half strength every 4 to 6 weeks to support vigorous leaf development. Reduce or cease fertilization during fall and winter when growth slows. Nitrogen promotes lush foliage.
Supporting Its Growth
‘Borsigiana’ is a climbing plant that benefits from physical support. A moss pole or other climbing structure encourages its vining habit and promotes larger, more fenestrated leaves. The plant’s aerial roots naturally attach to the porous surface, mimicking its growth on trees.
To train the plant, gently secure stems to the support with soft ties. Keeping the moss pole moist encourages aerial roots to anchor, providing stability and allowing the plant to absorb additional moisture and nutrients. This vertical support enhances the plant’s vigor and “Swiss cheese” leaf development.
Common Borsigiana Issues
Yellowing leaves are a frequent concern. Overwatering is a common cause, leading to yellowing lower leaves and potential root rot. Underwatering can also cause yellowing and browning leaf tips. Insufficient light or nutrient deficiencies may also result in yellow foliage.
Browning leaf tips or edges often indicate low humidity. Lack of fenestrations typically occurs in immature plants or those not receiving enough bright, indirect light. Common pests like spider mites and mealybugs can also affect ‘Borsigiana’, appearing as discolored leaves or visible insects. Regular inspection and interventions, such as adjusting watering, increasing humidity, optimizing light, or addressing pests, help maintain plant health.
