Why Isn’t my Spider Plant Growing?

Last Updated on August 4, 2022 by Stephanie

The reason why the foliage of spider plants not to grow is typically due to the fact that the temperature can be too hot or too low, the spider plant is shaded, or a deficiency or nutrients present in soil, or because of winter dormancy, when the growth rate slows dramatically.

Spider plants dont make their plantlets (also called baby spiders or) because of too much fertilizer that encourages growth of the foliage but at the expense of flowers, and also because they require a period of 12 hours of darkness in the night, for three weeks consecutively.

Read on to find out the reason why your web-like plant ( Chlorophytum comosum) isnt growing and the reason why your spider plant isnt producing plantlets or babies to propagate…

Why is My Spider Plant Not Growing?

Spider plants usually grow faster in the spring and summer and their growth may slow significantly in wintertime due to fluctuations in light and temperature.

Below I have listed the causes that cause an old spider plant to cease to grow in the order of most commonly cited reasons:

Temperature

The most frequent reason spider plants arent growing is that the temperature is either too low or too high.

The ideal temperatures to allow Spider plants to thrive can be found between the range of 65degF (18degC) 75degreeF (23degC) in the daylight, and 55degF (12degC) at night.

If temperatures are much more or less than the range, your spider plant could cease to grow.

The spider plants can be adapted and thrive in a variety of environments, however to ensure that they grow well, ensure that the temperature is within 65degF (18degC) 75degF (23degC).

When the temperatures are significantly lower than 55degF (12degC) for a prolonged period of time, or is higher than the temperature of 80degF (27degC) then the leaves of the spider plant show signs of tension by not growing and becoming brown, and then dying again.

Spider plants usually recover quickly once it has reached its temperature range that it prefers.

Low Levels of Light

Spider plants thrive in indirect, bright light. While they are tolerant of shade, a lesser intensity of light or fewer hours of sunshine can slow the growth of your spider plant, causing it to seems to not be growing.

This is the reason why in Winter the spider plant usually ceases to grow due to the lack of sunlight.

If the spider plant is in constant shade, it will not develop at the same pace and the leaves may become limp, pale and the variegated species may fade in color and become completely green.

Spider plants are able to adapt to less light , but to truly encourage growth, you must place your plant within a more bright region.

It is crucial not to put spider plants in direct sunlight especially after heavily shaded as this can make its leaves brown because of sunburn and stress from drought.

With indirect, bright light , your spider plant will begin to grow again.

Lack of Fertilizer

Spider plants may cease to grow due to a deficiency of nutrients. If your spider plant has been growing in this same container for a long time and the roots are exhausted, they can deplete their soils of nutrients, which could slow the growth of your plants during the summer and spring months.

Spider plants will grow to their maximum when they receive regular feeds during growth.

But fertilizing too often or with a high amount of fertilizer may cause the spider plants leaves to become brown as an indication of stress.

It is recommended to apply a half strength liquid houseplant fertilizer every month from the beginning of Spring to mid-Summer to ensure that the spider plant is getting every nutrient it needs to grow healthy.

Lack of Water During the Active Growing Season

Spider plants can be found throughout the year inside our homes since indoors provide the ideal conditions to grow, but they are most prolifically grown during the spring and summer months.

If they experience drought stress during their active growth, then the spider plant may cease to grow.

Stress from drought can be the result of:

  • Insufficiently watering.
  • Do not water too much.
  • Low humidity.

The spider plants grow in tropical regions and require more humidity than is normal for indoor environments.

Spray the leaves of the spider plant using water one time every week, and possibly more in summer or dry areas to create a humid microclimate which recreates the climate of their tropical habitat.

To ensure that spider plants grow in the spring and summer, the soil must be watered with a good amount of water to ensure its evenly moist to the root, however at the very top, the soil should be dry between watering sessions.

If the top inches of soil feels dry, it is the ideal moment to water in order to attain the ideal level of moisture to ensure that the spider plant gets enough water to allow for growth but not so much that it could cause root decay.

Spider Plant Babies Not Growing for Propagation

If your plants spider isnt producing babies, it is due to the fact that the plant isnt mature or the pot is too large , which diverts energy to the growing roots, instead of producing babies, or since spider plants are small day plants that need darkness to produce flowers, from which the baby plants develop.

The application of too much fertilizer increase the growth of foliage at the expense of flowers, and consequently the spiderrettes.

Spider plant babies develop when the plant produces its tiny white flowers, which are extremely delicate.

The spider plant, however, is a plant that blooms in the short days which only blooms when it is in at minimum twelve hours of continuous darkness each night for approximately three weeks..

The darkness of this time period indicates for the plant spider that it is the best time to bloom flowers in its natural environment.

To reproduce this at your home , ensure that your spider plant is placed in a dark area that is at least twelve hours in the evening.

If darkness is disturbed by switching on a light during the middle of the night, it can hinder flowering and also the development of the plantlets.

If you need to, use a bright covering over the spider plant minimum 12 hours per night.

Larger Pots Prevent Spider Plants Developing Babies

Spider plants are more likely to bloom more often (and consequently produce plantslets) when they are roots-bound within their containers.

In the event of limiting the roots inside the pot, this puts spider plants under a lot of stress, which encourages reproduction through growing plantlets. The spider plant tries to keep its existence under less favorable conditions.

When the plant grows placed in the larger pot, it tends to channel its energy towards developing the root systems, instead of the plantlets or foliage.

When the plant lives placed in an enormous pot that has lots of compost, there is less pressure to reproduce, which is the reason the plant isnt flowering or producing plantslets.

Larger pots can dry out more slowly, which increases the chance for root rot.

Put spider plant in containers or pots that are slightly bigger than their root ball, to encourage the growth of flowers and plantslets.

Key Takeaways:

  • When your plant isnt growing , it is usually due to it being in too much shade, or the roots have depleted their soils of nutrition, there is drought stress from under-watering or the spider plant has stopped growing in the winter period of dormancy.
  • Spider plants dont produce babies or plantlets when they arent within a minimum of twelve hours of dark each night for three weeks because they are plants that grow in short days. The over-fertilization of spider plants results in them not producing baby or flowers for propagation.
  • The ideal temperature at which spider plants can develop can be found between the range of 65 degF (18degC) 75degF (23degC) during the day, and 55degF (12degC) at night.
  • Spider plants thrive when they are in containers that are just little larger than that of their root balls.
