Philodendron Not Growing

How fast philodendron normally grows

Philodendron (including heartleaf philodendron, Philodendron Brasil, Philodendron micans, Philodendron gloriosum, and many others) is naturally a vigorous grower in its tropical forest habitat. In good indoor conditions during the growing season, most varieties produce a new leaf every 2 to 4 weeks. Growth slows substantially in autumn and winter and may pause entirely during the shortest days of the year. A philodendron that has not produced a new leaf in 4 to 6 weeks during spring or summer is underperforming and worth investigating. A philodendron that paused in November and resumed in March is behaving normally. The season matters significantly when diagnosing slow or absent growth.

Cause 1: Low light

Signs: The plant has not produced new leaves in several weeks during the growing season. It is positioned more than a few feet from a window, or in a room with small windows or northern exposure. Existing leaves are a darker, duller green than established growth. New leaves, if any, are smaller than older ones. The plant has been in the same location for months or years without moving.

Why it happens: Philodendron survives in low light but does not grow actively. Photosynthesis produces the energy for new leaf development; below a certain light threshold, the plant produces just enough energy for basic maintenance and not enough for new growth. Dim positions that seem adequate to human eyes are often insufficient for active plant growth.

Fix: Move to bright indirect light, ideally within a few feet of an east- or west-facing window, or farther back from a south-facing window. New growth should resume within 2 to 4 weeks. If moving is not possible, a grow light positioned 6 to 12 inches above the plant for 12 to 14 hours per day effectively supplements natural light.

Cause 2: Seasonal dormancy

Signs: Growth slowed or stopped in autumn or winter and the plant otherwise looks healthy. The position, watering, and care routine have not changed. The plant was growing well earlier in the year. Days are shorter and indoor light levels are lower than in summer.

Why it happens: Philodendron is a tropical plant that grows year-round in its native habitat, but responds to the reduced light of winter indoors by slowing or pausing growth. Even in a bright window, winter light intensity in temperate climates is significantly lower than summer light, and the plant allocates less energy to new leaf production.

Fix: No action needed if the plant is otherwise healthy. Reduce fertilizing to once every 6 to 8 weeks or stop entirely in winter, as fertilizing a dormant or slow-growing plant wastes nutrients and can cause salt buildup in the soil. Resume a monthly fertilizing routine in spring when growth resumes. A grow light can partially compensate for reduced winter light if faster year-round growth is desired.

Cause 3: Overwatering

Signs: Growth has stopped and the soil has been consistently moist. Some older leaves may be yellowing. The plant looks healthy overall but static. The pot feels heavy between waterings. The soil takes more than 1 to 2 weeks to dry in a warm, lit position.

Why it happens: Consistently wet soil causes low-level root stress and sometimes early-stage root rot, diverting the plant's energy to root health maintenance rather than new growth. Philodendron in wet soil also absorbs nutrients less efficiently, compounding the growth slowdown. The plant may look alive and decent while in this state because it is not in acute distress, but it is not thriving.

Fix: Allow the soil to dry more between waterings: water when the top 1 to 2 inches are dry. In low-light positions, soil stays wet much longer and watering frequency should be reduced accordingly. If root rot is suspected, remove from the pot and trim any dark soft roots before repotting in fresh mix. Growth should resume within 4 to 6 weeks of correct watering.

Cause 4: Nutrient deficiency

Signs: The plant has been in the same soil for more than a year and has not been fertilized. Growth is very slow despite adequate light, correct watering, and good temperature. New leaves are smaller than established growth or lighter in color. The soil looks exhausted and pale.

Why it happens: Potting soil nutrients are depleted within 6 to 12 months of use. Philodendron is a moderate to heavy feeder during its growing season and relies on regular fertilizing to sustain active growth once the initial soil nutrients are gone. A philodendron that has never been fertilized or not fertilized in more than a year is likely nutrient-deficient.

Fix: Begin a monthly fertilizing routine with a balanced liquid fertilizer diluted to half strength, from spring through summer. Apply only when the plant has been watered recently so the roots are not dry when receiving fertilizer. Do not fertilize in autumn or winter when the plant is growing slowly. Results should be visible as new, larger leaf production within 2 to 4 weeks of the first feeding in good light.

Cause 5: Root binding

Signs: The plant has been in the same pot for 2 or more years and was previously growing vigorously. Growth has gradually slowed over the past growing season. Roots are circling visibly at the soil surface or growing from drainage holes. The soil dries out very quickly after watering.

Why it happens: When a philodendron fills its pot with roots, there is little room for new root growth and the plant cannot take up water and nutrients efficiently. Root-bound plants also experience more frequent moisture stress as the reduced soil volume dries rapidly. Both factors slow leaf production.

Fix: Repot into a container 2 inches wider in spring, using fresh potting mix. After repotting, the plant should resume more active growth within 4 to 6 weeks as the roots expand into fresh soil. Provide a support for climbing varieties after repotting to encourage upward growth and larger leaf development.

Cause 6: Cold temperatures

Signs: Growth stopped or slowed significantly during cold weather. The plant is in a cool room, near an exterior wall, or near a cold window. Indoor temperatures in the space regularly drop below 60 degrees Fahrenheit at night. The plant otherwise looks healthy.

Why it happens: Philodendron is tropical and grows actively between 65 and 85 degrees Fahrenheit. Below 60 degrees Fahrenheit, growth slows considerably as root metabolism decreases. Below 55 degrees, the plant stops growing and may begin to show stress symptoms. Cold rooms, unheated garages in winter, or proximity to exterior walls in cold climates can all produce temperatures below the plant's active growth threshold.

Fix: Move to a warmer location and maintain temperatures above 65 degrees Fahrenheit consistently. Keep away from cold windows and exterior walls in winter. Growth should resume within 2 to 4 weeks of consistently warm conditions during the growing season.

Frequently asked questions

Why is my philodendron not growing?

The most common reasons philodendron stops growing are low light, seasonal slowdown in winter, and overwatering. Philodendron requires bright indirect light to grow actively; in dim conditions it survives but produces few or no new leaves. In winter, even philodendrons in good light slow down or pause completely because the shorter days reduce light intensity below what the plant needs for active growth. Overwatering stresses the root system and diverts the plant's energy to survival rather than new growth. Check the light level first — most philodendrons are in lower light than they appear to be — and check the season. If both are fine, look at the soil moisture and root health.

How do I make my philodendron grow faster?

The most effective steps to increase philodendron growth rate are: moving it to the brightest available indirect light position; fertilizing monthly with a balanced liquid fertilizer from spring through summer; ensuring the soil dries out slightly between waterings so root function is optimal; maintaining temperatures above 65 degrees Fahrenheit; and, if the plant is root-bound, repotting into a container one size larger to give the roots room to expand. Philodendrons are vigorous growers in good conditions and can produce a new leaf every 2 to 4 weeks in spring and summer. Providing a support for climbing varieties such as Philodendron gloriosum or heartleaf philodendron also encourages larger, more mature leaf development.

How long does it take for philodendron to grow a new leaf?

In ideal conditions during the growing season (spring through summer), philodendron can produce a new leaf every 2 to 4 weeks. In lower light or in autumn and winter, this slows to one leaf every 4 to 8 weeks, and may pause entirely in very low light or very cold conditions. A new leaf begins as a tightly rolled cataphyll (a protective sheath) at the growing tip and takes anywhere from a few days to 3 to 4 weeks to fully unfurl, depending on the variety and growing conditions. If the new leaf is unfurling but slowly, that is different from no new growth appearing at all: the former is a pace issue, the latter indicates a care or environmental problem.
