Lemon Lime Philodendron Origin

These tropical plants’ scientific name is Philodendron hederaceum, with lemon lime philodendron and sweetheart vine as their common names.

They originated in Central and South America. These hybrid plants are part of the Araceae family.

How to Care for Lemon Lime Philodendron

As these plants grow through their stages, growers will witness different leaf colors. Typical colors are lemon to neon green to pink-yellow and lime green to bright yellow-green distinction. These philodendrons can grow as stake plants or hanging plants. These plant care guidelines enable growers to enjoy their beauty all year round.

Light and Temperature

Lemon lime philodendrons flourish in bright, indirect light, and strong, direct light will scorch their leaves. However, not enough light will stunt their growth and make them leggy. Near a window works but not directly in front of a window. Glass magnifies the sun and burns the leaves.

Additionally, these indoor plants will survive in low-light settings while brightening up the room. Still, bright, indirect light is best, but avoid placing them on the windowsill. They will thrive in a location that doesn’t have shade or direct sunlight. Raise the pot or use a hanging planter to create the required balance.

These sweetheart vines grow well in temperatures ranging between 65 to 85 degrees Fahrenheit throughout the day. Though slightly above 85 degrees is tolerable. Night temperatures can go as low as 55 degrees Fahrenheit.

Their tropical heritage means they love being cozy in warmth. But keep these houseplants away from fires, heaters and vents. During the winter months, lemon lime philodendrons need the temperature to remain consistent. Fluctuations in temperatures and low temperatures will only upset the plants and stunt their growth with a prolonged recovery.

Most indoor humidity is acceptable for these beauties, though higher humidity helps these indoor plants grow larger leaves. Occasional misting helps these plants thrive, keeping the moisture in the air. When winter arrives, cut back on the misting.


Monitor the lemon lime philodendrons for a few days after they have arrived in their new home. Evaporation of water depends on the season, lighting conditions and temperature. While monitoring these plants, growers easily learn in due time the ideal watering schedule, though it fluctuates.

Each season, the watering differs for these sweetheart vines. During the spring and summer months, the water evaporates faster than in winters, where the evaporation slows down because of shorter days.

Use your finger to test the topsoil of the potting mix. When the soil is dry, water. If it’s wet, don’t water the plants. Gradually, growers develop an awareness and know when to water their plants and create a watering schedule.

Overwatering causes bacteria growth in the roots, leading to root rot. When philodendrons have root rot, it is a common problem and their biggest problem. These houseplants suffer and become weak, and die quickly. The only way to save these sweet vines is to take cuttings and regrow.

Again, feel the texture of the potting mix. Enable the soil to dry out before watering these indoor plants once more. Removing the water from their under dish also helps keep the bacteria buildup at bay.


Lemon lime philodendrons enjoy liquid fertilizer during spring and summer, the growing months. Fertilizing during these times supports bigger and lush green leaves. Try using a balanced fertilizer like pellets or diluted liquid feed. When winter arrives, stop or reduce fertilizing.

Natural or organic fertilizers are the best, though occasionally giving these plants regular fertilizer helps keep them thriving and healthy.

When the plants reach four to six weeks old after propagating, start using a 10:10:10 fertilizer — Nitrogen, phosphorus and potassium.


These sweetheart vines rarely bloom, but if they do, spring to late spring is when growers will see them flower. In general, they don’t bloom, even in the outdoors.

If it happens, white, delicate flowers appear that are not ornamental and are very simple looking. Because these flowers are fragile, they have a brief life and do not change their look.


Lemon lime philodendrons don’t require frequent pruning. Cut the lower area of these plants so they grow fuller. Or, simply trim off the yellow, damaged or old foliage to shape the plant. Even cut vines that appear messy or too long so the houseplants can keep their shape.

Use sterilized pruning shears or sharp scissors, cut below the node where the stem and leaves cross each other. At these points, go down a quarter to half and inch, cutting there.


These sweetheart vines require repotting when they outgrow their containers in the second or third year of growth. Seeing roots growing out of their drainage holes is the first sign of needing a new home.

Hanging baskets drain well, and terracotta pots have pores that help water drain well. Plastic pots are not good unless they have plenty of drain holes, not just one on the bottom.

Repotting requires moving these plants to bigger planters, around one to three inches larger. Try not to go any larger because these houseplants will drown. With too much room, their potting mix remains wet for too long, allowing bacteria to survive. The result is root rot.

Drainage holes are part and parcel of growing philodendrons. That way, excess water flows easily into the saucer. Use well-draining soil like peat moss.

Repot during spring and summer, growing months. But avoid repotting when the temperatures are high and very hot. Cool and warm weather is the best time if possible.


These lemon lime philodendrons rarely have pest infestations unless they have poor growing conditions. Some growers experience a whole lifespan without ever dealing with pests.

A stressed or weak indoor plant will draw pests and be under attack. Mealybugs and spider mites are the most common insects. These buggers are harmful because they suck the sap out of these beauties, taking their nutrients.

Again, proper light, watering and feeding will prevent any pests from attacking sweetheart vines. But if they get pests, treat them with insecticidal soap spray. Neem oil also works and even as a preventive measure.

Keep treating the infected plants until there are no more signs of insects. Try to keep the infected plants away from the healthy plants, so the buggers do not spread.


Pests can also carry diseases, but other than that, these philodendrons are disease resistant. These houseplants are durable and live a long time without problems. They’re perennials and continue to grow for at least two years. Their foliage and vines live for years, and these plants even survive if their leaves fall off.

Like most plants, bacterial, fungal infections and root rot are their biggest enemies. Almost entirely, moisture and overwatering play a significant role. Mainly if the water can not evaporate quickly enough to dry out the potting mix, these plants will get sick.

These diseases are preventable if the surroundings have enough air circulation, and watering never happens. Suppose they catch a disease. It’s almost fatal.

Try removing the infected area from the roots and leaves. Mild root rot might go away by using a fungicide that contains flutriafol. Transplanting, changing potting soil and letting the plant dry out without water for at least a week might also work.

How to Propagate Lemon Lime Philodendrons

Most growers find lemon lime philodendrons easy to propagate with little effort. There are two ways: stem cutting with water or potting mix.

The best time to propagate these houseplants is spring and summer, during the growing season. Winter is not a good season. These sweetheart vines like to rest and do not want disruption by having to adjust to changes in their dormant period.

When these indoor plants have grown large, and bushy is the ideal time to propagate. It’s also a great way to shape and reduce the size of the plant while making new ones.

Stem Cuttings

  • Look over the plant and find a healthy long stem about six inches with a few leaves.
  • Using sterilized, sharp pruning shears or scissors, cut the stem below its node, about a quarter to half an inch. This is where the stem connects to the leaf.
  • For potting mix, dip the end of the cutting into some rooting hormone and plant it gently into the soil. 
  • Have the cutting remain in the shade for two to three weeks and slowly expose the plant to indirect light.
  • For water propagation, place the cutting in a glass container (jar, vase, cup) of water. Now, wait for the roots to form, about two to three weeks.
  • Water propagation has the benefit of monitoring the roots through the glass jar.
  • After the roots have developed, longer than an inch, move the cutting to a planter with a new potting mix. 
  • Water the soil while keeping the sweetheart vine warm in the air with bright and indirect sunlight.

Frequently Asked Questions

What is the difference between neon pothos and lemon lime philodendron?

Neon pothos and lemon lime philodendron are both from the Araceae family, so they are cousins. They differ, with neon tendrils grow six to 10 feet in height while the sweetheart vines grow eight to 24 inches. However, the philodendron has tendrils that can reach 15 feet.

Neon’s leaves are smaller, about four to six inches wide, while the lemon lime is seven to 10 inches long and 12 inches wide.

Though their leaves are the same heart shape, philodendron has slimmer leaves and feels softer. Yet, growers will notice pothos leaves appear thicker and are waxy to the touch. Sweetheart vines have leaves that bend inward, while the neon leaves are straight in the stem.

These pothoses have a single aerial root per stem, while the lemon limes have several tiny roots per stem, creating a more jungle or bushy look. Colors seem similar but are different, with neon being neon and the philodendron having a bright shade of green with pinkish and brown hues.

Neon pothos can bloom but not indoors, and the lemon lime philodendrons don’t bloom at all, though rarely.

Is lemon lime philodendron a climber?

These beauties are climbers and can grow into robust plants. Plant lovers can train them as trailing plants or climbers under the right growing conditions. These houseplants will grow up trellis or pillars. Some owners use moss poles. It’s essential to help them climb because they can get bushy and grab onto anything. 

How big does the lemon line philodendron grow?

Some growers report their sweetheart vines reaching 24 inches tall with tendrils extending 15 feet long. 

Is lemon lime philodendron toxic to pets?

These indoor plants are very toxic if eaten. The lemon lime philodendron carries calcium oxalate crystals that cause mild to severe symptoms. Swelling lips and mouth, difficulty breathing and reactions can reach the eyes. Crystal calcium oxalate protects the plant from eaters in each natural habitat. That’s why it’s so toxic.

Final Thoughts

These lemon lime philodendron plants add beauty to the indoors with their vibrant green colors. Hues of yellow, brown and pink foliage trail and cascade, growing abundantly.

Keep the sweetheart vines in warm temperatures and bright, indirect light away from windows. Peat moss is the best potting mix, keeping the water well-drained. Overwatering is their worse enemy, so lean on drier soil.

Trimming these beauties will keep them looking bushy and robust. As a versatile evergreen plant, growers can keep them bushy or help them climb on a trellis or moss pole.

Follow this guide to ensure these houseplants have the best care and return the favor by purifying the air and adding life to the indoors.
