Light is an essential element for any living plant, and rubber plants are no exception. With its attractive dark green leaves and ability to survive a variety of light conditions, the rubber plant (Ficus elastica) is one of the most common houseplants around.

From bright direct sunlight to low indirect light, this resilient species can thrive in many different environments. For best results, place your rubber plant in an area that receives bright filtered or indirect sunlight throughout the day.

If you lack natural light from windows, you can supplement with artificial grow lights. Rubber plants tolerate both strong and weak sources of light but be careful not to keep it in too much direct sun as this will cause leaf burn or discolouration over time. Lastly, remember to rotate your rubber plant every few weeks so that all sides receive equal amounts of sunlight as it grows!

Rubber Plant Light


Temperature is an important factor in growing rubber trees, or Ficus Elastica. For optimum growth, these plants must have temperatures between 15-24 degrees Celcius during the day and no lower than 13 degrees at night.

Rubber trees can also tolerate temperatures that drop to 50 degrees or higher, but anything in between can cause serious damage to the health of the plant. In general, it’s best to keep your rubber tree out of direct sunlight as this will raise its temperature too high and put stress on the plant.

It’s also important to check your plants regularly for signs of heatstroke such as limp leaves and wilting stems. If you notice any of these symptoms, move your plant immediately into a cooler area where it will receive indirect light and plenty of air circulation. With proper care, temperature regulation can help ensure healthy growth for your ficus elastica!

Soil is an important factor in the growth of any plant. Rubber plants, also known as Ficus Elastica, are a popular houseplant because they require minimal maintenance and thrive in most environments.

But for optimal health and growth, rubber plants need nutrient-rich soil that can hold moisture but still drain well. Successfully growing a rubber plant starts with selecting the right soil.

The best potting mix for rubber plants should contain peat moss, perlite or vermiculite to help with drainage and aeration; organic matter such as composted bark chips or coconut coir to provide nutrition; and some sand to further improve drainage while maintaining the necessary moisture level. It’s also important to avoid soils containing heavy clay which may make it difficult for roots to spread out and absorb nutrients needed for healthy growth.

Pot Size

Pot size

Pot Size is an important factor to consider when growing a Rubber Plant (Ficus Elastica). Rubber plants are considered easy to maintain and can grow in many different types of pots.

But the container size should be chosen carefully, as it can affect the overall health of your plant. A pot that is too small will restrict the growth of your Rubber Plant.

The roots will become crowded, and it might not be able to take in enough nutrients from its soil. This can cause stunted growth or yellowing leaves. On the other hand, if you choose a pot that’s too big, it could allow water to stay stagnant for far too long and cause root rot. When selecting a container for your Rubber Plant, pick one that’s only slightly bigger than its current pot so you don’t shock its roots with an overly large amount of soil.
