Philodendron Mamei is a stunning tropical plant known for its large, lush green leaves with pink veins. With the right care and conditions, this philodendron makes an excellent houseplant that can grow quite large over time. This plant is not difficult to grow but does require some specific care to thrive.

Light Requirements

Philodendron Mamei thrives in bright, indirect light. Place it near an east or west facing window where it will receive several hours of sunlight filtered through a sheer curtain. Avoid direct southern light exposure, which can scorch the leaves.

This philodendron will adapt to lower light over time, but growth may slow. The foliage color may also fade without enough light. Keep the plant within 5-10 feet of a window to maintain its vibrancy. Rotate the plant periodically so all sides receive equal light exposure.

Ideal Temperature

Warm indoor temperatures between 65°F to 80°F are ideal for Philodendron Mamei. Avoid placing this plant in drafty areas or allowing it to get cold below 55°F. The leaves are susceptible to chilly damage.

During summer months, temperatures above 80°F are fine as long as the humidity is increased. This plant cannot tolerate extreme heat over 90°F for extended periods of time.

Watering and Soil

Philodendron Mamei prefers a consistently moist but not soggy soil. Water the plant thoroughly whenever the top 1-2 inches become dry. In summer months, this may be every 5-7 days whereas in winter it may be every 10-14 days. Take cues from the soil rather than a set schedule.

These plants thrive in loose, well-draining soil. Use a quality potting mix amended with perlite, orchid bark and charcoal. Self-watering pots can help maintain evenly moist soil. Allow excess water to drain fully after watering to prevent soggy roots.

Humidity

High humidity is key to growing lush, healthy Philodendron Mamei plants. Ideal levels are 60-80%. Place the pot atop a pebble tray filled with water or use a humidifier nearby to elevate the moisture around the plant. Mist the leaves every few days for an extra humidity boost.

Keep this plant away from heating vents, fireplaces and other sources of dry air. The leaves can dry out and brown along the edges when humidity is too low.

Fertilizer

During the growing season from spring through summer, feed Philodendron Mamei with a balanced liquid fertilizer diluted by half. Fertilize monthly to provide key nutrients the plant needs for growth. Reduce feeding in fall and winter when growth naturally slows.

Avoid over-fertilizing which can burn the leaf tips. Only use a fertilizer formulated for houseplants following label instructions for dosage and frequency.

Pruning

Prune off any dead, damaged or diseased foliage as needed to maintain the health and shape of the plant. Snip spent leaves back to the main stem.

You can also prune Philodendron Mamei to control size and create a fuller, bushier plant. Cut back leggy stems or trim off the top few inches of the vines. New shoots will usually grow from just below the cut. Avoid removing more than 20% of foliage at one time.

Propagation

Philodendron Mamei can be easily propagated by stem cuttings. Take a cutting with at least 2-3 leaves from a mature, healthy plant. Remove lower leaves and place the cutting in water or moist potting mix. New roots will sprout in a few weeks to months.

Once rooted, plant the new start in a pot with drainage. Keep the soil consistently moist while it establishes. Propagating from cuttings is an easy, cost-effective way to create new Philodendron Mamei plants!

Common Problems

Philodendron Mamei is generally resilient but can develop issues with improper care:

• Leaf browning – Usually caused by low humidity. Increase moisture in the air and mist regularly.
• Leaf spots/blight – Water-soaked lesions caused by bacterial or fungal disease. Improve air circulation and don’t overwater.
• Slow growth – Can indicate too little light or fertilizer. Move to a brighter location and fertilize in the growing season.
• Drooping leaves – RESULT OF UNDERWATERING. Check soil and water when the top layer is dry.
• Root rot – Caused by soggy soil. Allow soil to dry out between waterings and use well-draining mix.

Tips for Success

• Provide bright, indirect light from an east or west window
• Maintain warm temperatures between 65°-80°F
• Keep the soil consistently moist but not waterlogged
• Increase humidity with a pebble tray or humidifier
• Fertilize monthly in spring and summer
• Prune to control size and shape as desired
• Propagate new plants from stem cuttings
• Watch for leaf browning, blight and slowed growth

With the right care, Philodendron Mamei makes a statement piece in any indoor collection. Its large split leaves with pink veins provide beautiful, tropical texture that can’t be beat! Follow these tips and enjoy this plant for many years to come.

Frequently Asked Questions

How big do Philodendron Mamei plants grow?

Given proper indoor conditions, Philodendron Mamei can grow quite large, up to 3-4 feet tall and wide. The vines can reach 6 feet long or more as the plant matures over time. Pruning and training onto support structures helps manage its size.

What type of support does a Philodendron Mamei need?

Philodendron Mamei has climbing vines, so providing a support structure helps the plant grow upright rather than sprawling along the floor. Use a moss pole, coconut coir totem, or simple wooden stake for the vines to attach to. Avoid wire frames which can damage the soft stems.

Is Philodendron Mamei rare?

Philodendron Mamei is uncommon and harder to find than other houseplant philodendrons, which adds to its appeal. But it is steadily gaining popularity as more nurseries propagate this variety. With proper care, Mamei philodendrons can also be propagated at home from cuttings.

What is the best potting mix for a Philodendron Mamei?

These plants need a loose, chunky and fast-draining soil. A quality potting mix amended with perlite, orchid bark and charcoal provides the aeration and moisture control Mamei philodendrons require. Heavy potting soil can lead to root rot.

Why are the leaves on my Philodendron Mamei turning brown?

Leaf tip browning is generally caused by low humidity. Mamei philodendrons prefer 60% humidity or higher. Increase humidity around the plant by using a pebble tray, misting regularly or using a humidifier. Keep it away from heat sources that can dry the air.

Should I mist my Philodendron Mamei?

Misting is an excellent way to provide added moisture and humidity to this tropical plant. Mist the leaves every couple days, or whenever the air feels dry. Avoid getting water directly on the crown of the plant to prevent possible rot. Use room temperature water for misting.

Why are the older leaves on my Philodendron Mamei dying?

It’s normal for philodendrons to shed their oldest leaves as the plant grows. The lower leaves naturally die off over time. Just prune these off at the base of the stem. As long as new growth appears healthy, old leaf drop is nothing to worry about.

How do I revive a drooping Philodendron Mamei?

If the leaves are drooping, it’s a sign of under-watering. Check the soil moisture and water thoroughly if dry. Philodendron Mamei should be kept consistently moist but not soggy. Increase watering frequency in summer or in drier air. Drooping leaves may recover in a few days after watering.

What type of fertilizer should I use?

Opt for a balanced liquid houseplant fertilizer diluted by half strength. Apply monthly through the active growing period in spring and summer. Look for a fertilizer labeled for tropical foliage plants. Reduce or stop fertilizing in fall and winter when growth slows.

Conclusion

With large, tropical-looking leaves and vigorous climbing vines, Philodendron Mamei adds drama to any indoor plant collection. Caring for this philodendron simply requires bright, indirect light and consistent moisture along with warm temperatures and humidity. Allow the soil to dry slightly between waterings and fertilize monthly during the growing season. Prune when needed to control size and shape. Watch for pests, diseases, and cultural issues like leaf browning and troubleshoot appropriately. With proper care, Philodendron Mamei makes a stunning focal point in any indoor space. Its lush emerald and pink foliage cascading from a support structure creates a tropical look suitable for offices, living rooms and sunrooms.
