ByRimon Chowdhury Updated on

Have you ever brought home a tiny, adorable philodendron from the nursery, only to wonder if it’s secretly planning a hostile takeover of your living room? You’re not alone! It’s one of the most common questions we get here at Greeny Gardener.

You see that perfect spot on your bookshelf and imagine a few charming leaves trailing down. But then a flash of doubt hits—will it stay that way, or will you be wrestling with a jungle vine in a year?

I promise, this complete how big does philodendron get guide will clear up all that confusion. We’re going to walk through everything you need to know, from the different types of philodendrons and their growth habits to the exact steps you can take to manage their size like a seasoned pro.

So, let’s demystify your plant’s potential and give you the confidence to grow a philodendron that’s the perfect size for your space.

The Two Worlds of Philodendrons: Vining vs. Upright Growth

Before we can talk about size, we have to understand that “philodendron” isn’t just one plant. It’s a huge family with two main personalities: the climbers and the self-headers (or upright growers).

Thinking about which type you have is the very first step in predicting its future size. It’s like knowing whether you adopted a Corgi or a Great Dane!

Vining (Climbing) Philodendrons

These are the classic trailers you see gracefully spilling from hanging baskets or climbing up moss poles. Their defining feature is their long, flexible stems that produce leaves and aerial roots at each node.

In the wild, these aerial roots help them cling to trees, scrambling up toward the forest canopy. In our homes, they’ll either trail downwards or eagerly latch onto any support you provide. Don’t worry—these vining types are perfect for beginners!

  • Examples: Heartleaf Philodendron (Philodendron hederaceum), Brasil Philodendron, Micans Philodendron, Pink Princess Philodendron (technically a vining climber).
  • Growth Habit: Their length is the main measure of their “size.” Left to trail, their vines can easily reach 10-20 feet or more indoors over several years, though the leaves might stay smaller.

Upright (Self-Heading) Philodendrons

Upright philodendrons grow from a central base, pushing out new, large leaves from the center. They don’t produce long vines. Instead, they grow outwards and upwards, becoming wider and taller over time.

These varieties are often prized for their dramatic, statement-making foliage. They create a lush, bushy appearance and are fantastic floor plants. Their growth is more contained, but their individual leaves can get huge.

  • Examples: Split-Leaf Philodendron (Thaumatophyllum bipinnatifidum, formerly Philodendron selloum), Philodendron ‘Birkin’, Philodendron ‘Moonlight’, Philodendron ‘Congo Rojo’.
  • Growth Habit: Their size is measured in height and width. A mature upright philodendron can reach 3-6 feet tall and just as wide indoors, with individual leaves spanning over a foot.

So, Exactly How Big Does a Philodendron Get Indoors?

Now for the main event! The ultimate size of your philodendron depends heavily on its species and the care it receives. Here’s a realistic look at what you can expect from some of the most popular varieties when grown as houseplants. This section is the core of our how big does philodendron get care guide.

Size Guide for Popular Vining Philodendrons

  • Heartleaf Philodendron (P. hederaceum): This is the quintessential trailing plant. Indoors, its vines can easily grow to 10 feet long, but they can be kept much shorter with regular trimming. I’ve seen some truly majestic ones reach over 20 feet in ideal conditions!
  • Pink Princess Philodendron: While it’s a slower grower, the Pink Princess is a climber at heart. With a pole to support it, it can reach 4-5 feet tall, with vines that can extend even further if left untrimmed.
  • Micans Philodendron: Known for its velvety, iridescent leaves, Micans has a similar growth habit to the Heartleaf. Expect vines to reach 8-10 feet in length over time, creating a stunning cascade of color.

Size Guide for Popular Upright Philodendrons

  • Split-Leaf Philodendron (T. bipinnatifidum): This is one of the giants! Even indoors, a mature Split-Leaf can become a magnificent floor plant, reaching 5-6 feet tall and 5-8 feet wide. Its deeply lobed leaves can grow up to 2-3 feet long. Give this one plenty of room!
  • Philodendron ‘Birkin’: A more compact and manageable variety, the Birkin typically stays around 2-3 feet tall and wide, making it a perfect tabletop or shelf plant.
  • Philodendron ‘Moonlight’: Famous for its vibrant chartreuse new leaves, the Moonlight is another tidy grower. It generally forms a mound about 2 feet tall and 2 feet wide.

Key Factors That Influence Your Philodendron’s Size and Vigor

Your plant’s genetics set the blueprint, but its environment determines if it reaches its full potential. Understanding these factors is key to mastering how big does philodendron get best practices and encouraging healthy, sustainable growth.

  1. Light: This is the most crucial ingredient. Philodendrons thrive in bright, indirect light. A plant in a bright spot will grow faster, produce larger leaves, and have a more robust root system. Low light leads to slow, leggy growth with smaller leaves.
  2. Pot Size: Philodendrons don’t mind being a little snug in their pots. However, a severely root-bound plant will have its growth stunted. Repotting every 1-2 years into a pot that’s 1-2 inches larger in diameter gives it fresh soil and room to grow.
  3. Water & Humidity: Consistent watering—allowing the top inch or two of soil to dry out between waterings—fuels growth. High humidity (above 50%) mimics their native rainforest habitat and encourages larger leaves and more vigorous aerial root development.
  4. Support (for Vining Types): Giving a vining philodendron something to climb, like a moss pole or trellis, is a game-changer. This encourages it to produce larger, more mature leaves, a phenomenon known as phenotypic plasticity. It’s a simple trick to get that jungle look!
  5. Fertilizer: Food is fuel! During the growing season (spring and summer), feeding your philodendron with a balanced liquid fertilizer every 4-6 weeks will provide the nutrients it needs for steady growth. Consider using an eco-friendly how big does philodendron get approach with organic options like worm castings or fish emulsion.

Your Pruning Toolkit: How to Control Size and Encourage Fuller Growth

Feeling a bit intimidated by those 10-foot vines? Don’t be! Pruning is your superpower. It’s the easiest way to manage your plant’s size and is one of the most important how big does philodendron get tips I can share.

Regular trimming doesn’t harm your plant; in fact, it encourages it to become bushier and more lush. Here’s how to how big does philodendron get the exact shape you want.

When and How to Prune

The best time to prune is in the spring or early summer when the plant is in its active growth phase. Use a pair of clean, sharp scissors or pruning shears.

  • For Vining Types: Simply snip the vine to your desired length. Make your cut about a quarter-inch above a leaf node (the little bump where a leaf grows from the stem). This will encourage the plant to send out new growth from that node, often resulting in two new stems!
  • For Upright Types: You can’t shorten an upright philodendron, but you can remove lower or older leaves that are yellowing or damaged. Cut the leaf stalk (petiole) close to the main stem. This tidies up the plant and directs energy toward new growth.

The Magic of Propagation

The best part about pruning? Free plants! Nearly every piece you trim from a vining philodendron can be easily propagated in water or soil. This is a wonderfully sustainable how big does philodendron get practice. Just pop the cutting into a jar of water, ensuring at least one node is submerged, and wait for roots to appear.

Common Problems with Philodendron Size (And How to Fix Them)

Sometimes, your plant’s growth can be a little… confusing. Here are some common problems with how big does philodendron get and simple solutions.

Problem: My plant is “leggy” with long, bare stems.

Cause: Not enough light! The plant is stretching to find more sun.

Solution: Move it to a brighter location with indirect light. Prune back the leggy stems to encourage bushier growth closer to the base of the plant.

Problem: My plant isn’t growing at all.

Cause: This could be due to a few things: insufficient light, being severely root-bound, or a lack of nutrients.

Solution: Assess its conditions. Does it need more light? Check the drainage holes for roots poking out—it might be time to repot. If it hasn’t been fed in a while, give it a dose of fertilizer during the growing season.

Problem: The new leaves are much smaller than the old ones.

Cause: This is often a sign that the plant needs more light or, for vining types, something to climb. It could also indicate a need for fertilizer.

Solution: Move it to a brighter spot and consider adding a moss pole. If you haven’t fertilized recently, now is a good time.

The Surprising Benefits of Letting Your Philodendron Grow Big

While managing size is important, there are some incredible benefits of how big does philodendron get when you give it the space to thrive.

A large, mature philodendron is an air-purifying powerhouse, effectively filtering common indoor toxins from the air. A lush plant contributes to a calmer, more natural-feeling environment, which can reduce stress and boost your mood.

Creating a “green wall” with vining philodendrons or letting a large upright variety become a living sculpture in your home is a beautiful and eco-friendly way to decorate. It connects you with nature right inside your own space.

Frequently Asked Questions About Philodendron Size

How can I make my philodendron grow faster?

To speed up growth, provide optimal conditions. The biggest levers are bright, indirect light and consistent feeding during the spring and summer. For vining types, adding a moss pole for it to climb will also dramatically increase its growth rate and leaf size.

Do philodendrons grow bigger in bigger pots?

Yes, to an extent. A larger pot provides more room for roots to expand and access to more nutrients, which supports bigger top growth. However, be careful not to put a small plant in a massive pot, as this can lead to the soil staying wet for too long and causing root rot.

Can a philodendron get too big for my house?

For most common varieties like the Heartleaf or Birkin, it’s highly unlikely. Their size is very manageable with simple pruning. The only one to truly plan for is the Split-Leaf Philodendron (T. bipinnatifidum), which can become a very large floor plant over many years.

Go Forth and Grow!

There you have it! The question of “how big does philodendron get” isn’t about one single answer, but about understanding your specific plant and the simple factors you control.

Whether you dream of a lush cascade of vines down your wall or a stately floor plant with giant leaves, you now have the knowledge to make it happen. You are in the driver’s seat.

So embrace the growth, don’t fear the pruning shears, and enjoy the incredible journey of watching your little green friend transform. Happy gardening!
