How to Make Houseplants Grow Faster? (6 Tips)

If you notice your plants are growing slower than usual, or you’re just impatient and can’t wait to see your baby plants mature, you might be thinking of ways to facilitate their growth. So, how to make houseplants grow faster? The short answer is to give them everything they need.

While each plant has its own needs; water, light, humidity, temperature, and fertilization are detrimental factors to healthy plant growth. Provide the plant with the proper conditions, and you can expect fast plant growth. The right pot size can also help make plants bigger.

Continue reading this article to learn about six tips that’ll help you grow houseplants quickly. Stick around!

1.   Provide Adequate light

Adequate lighting

Generally, houseplants come from tropical or subtropical regions. These plants make the upholstery of forests, so they don’t get much direct sunlight. To mimic the same natural growth conditions, you should grow indoor plants in areas with bright, indirect sunlight.

Most houseplants also need at least six hours of sunlight exposure. If you’re growing the plants under artificial lights, 12 to 14 hours would be ideal for most low and medium-light houseplants.

All plants—even low-light plants—need light for photosynthesis to produce the energy required for growth, blooming, and seed production. Too little or too much light has adverse effects on plants’ growth.

Here are a few tips to make sure your houseplants get adequate light:

  • Make sure your windows are clean; so they don’t filter light or heat
  • Wipe the leaves with a wet cloth to remove dust. That’s because dust can block light from leaves, reducing photosynthesis
  • For low-light plants, place them in front of north-facing windows
  • Mount the plants to ceilings, regardless of the window direction, as overhanging roofs provide partial sunlight
  • Place medium-light plants near east or west-facing windows
  • For high-light plants, put them in front of south-facing or southwest windows, where it’s bright

2.   Water them When Necessary

Watering plants

Watering your plants is vital for proper growth, especially during the growing season (from spring to fall). Without water, plants will slow down food production and eventually wilt and die.

However, feeding them too much water would do them more harm than good.

That’s because over-watering your plants leads to soggy soil, which blocks oxygen entry. As a result, the roots suffocate and die, affecting the entire plant. Not to mention, excess water encourages mold growth and leads to root rot.

To avoid the watering dilemma, you should check whether or not your plant needs water before feeding it. One way to be certain about your plant’s water needs is through the finger test.

Here’s how to do it:

  • Stick your fingers around two inches deep into the soil—preferably near the root area
  • Gently lift your finger out of the soil and examine it
  • If your finger comes out dry or with little soil, that’s your sign to water your plants
  • If soil particles are sticking all over your finger, that means the soil is moist, and you should skip watering that day

You can record each time you water the plants and use that information to create a watering schedule customized for each plant.

3.   Choose the Right Water

Aside from the water amount, water quality is important to support proper growth. In general, plants will be fine with rainwater or unsoftened tap water. During the water softening process, sodium ions exchange the calcium and magnesium ions found in the water.

Most plants need a trace amount of sodium. That way the excess mineral in soft water builds up in the soil, which alters its structure. As a result, it reduces soil drainage, eventually harming your plants.

Likewise, hard water contains large amounts of minerals, like calcium and magnesium. While these minerals provide plants with some benefits, excessive calcium and magnesium salts can have adverse effects. Why?

That’s because both salts increase soil alkalinity, which is unsuitable for most plants. Generally, plants thrive in slightly acidic to neutral soil (pH 6 to 7.5)—some houseplants even prefer an acidic pH of 5.5.

4.   Provide Adequate Temperature and Humidity


Since most houseplants come from tropical and subtropical environments, it’s only natural that they prefer warm temperatures.

As a rule of thumb, keep foliage houseplants at temperatures between 70ºF and 80ºF during the day. Flowering indoor plants, on the other hand, grow best from 55ºF to 60ºF. At night, lower the day temperature from 10º to 15ºF to recover the lost moisture.

Aside from succulent plants, most indoor plants prefer humidity. Providing plants with high humidity can be tricky since indoor environments are relatively dry.

Still, several ways can help you increase indoor humidity for plants without suffocating you. These include:

1.   Group Plants

Naturally, plants lose absorbed water through a process known as transpiration. When plants transpire, they increase the surrounding moisture by releasing water vapor on the leaf’s surface and into the air.

You can take advantage of this natural process to create a more humid environment for plants. All you need to do is group houseplants that require high humidity together and let transpiration do the rest of the work.

2.   Make a Humidity Tray

Placing plants in a water-filled pebble tray is another easy alternative to increase humidity for houseplants. The water will evaporate and create a humid climate for the plants.

Here’s what you need to do:

  • Fill a clean tray with at least one inch of pebbles, stones, or gravel
  • Put the houseplant pots on the pebbled tray
  • Pour water into the tray but don’t let the water directly contact the containers to avoid root rot.

3.   Use a Humidifier

Humidifiers are probably the easiest option to adjust room humidity. However, those devices will increase the entire room’s humidity, not just around the plants. So, humidifiers might be suitable if you group the houseplants in one place.

5.   Fertilize the Soil

Adding fertilizer to soil

A well-fertilized soil is important in supporting fast plant growth. Generally, you should feed your plants in early spring using a high-quality fertilizer. You can also add organic compost to the soil and support the soil microbes that benefit plants.

That said, you should test the soil pH before applying fertilizers, as nitrogen and phosphate compounds can acidify the soil.

In winter, it’s best to cut down on fertilizing the soil since most plants are dormant in cold weather. However, you can feed houseplants if they’re still active during winter.

6.   Choose the Right Pot Size

If you want your plant to grow faster, it’s only natural to allow some room for its growth. When the pot is small, it restrains the roots from getting bigger. As a result, it slows the plant’s growth.

Conversely, a large pot will collect water at the bottom, making it harder for the roots to reach the water. That’s especially true for plants with shallow roots. That can lead to waterlogged soil and root decay.

Here are a few tips to tell if a pot is too small:

  • The roots grow out of the pot’s drainage holes
  • Water runs through the pot and drains fast
  • Formation of root balls that reach the bottom of the pot
  • Plants pop out of the container because of root balls pushing the plant upwards

Figuring out how to make houseplants grow faster can satisfy your impatient self. After all, you’ve been showering your plants with care and love, and want to see the results.

To achieve fast houseplant growth, you’ll need to provide them with bright, indirect light and water them when needed. In addition, you should fertilize the soil and place indoor plants in a warm, humid environment.

Couple that with changing the pot size every time the roots get crowded, and you can expect houseplants to mature and boast their beautiful foliage quickly.
