Water
Although rubber trees need regular watering, too much water can cause root rot. In general, you’ll want to water these plants when the top 1 to 2 inches of soil feels dry.
Light
Rubber trees grow best in bright, indirect light, but they can also tolerate lower light conditions. Too little light, however, can cause these plants to get leggy or drop their leaves, while too much direct sun can result in sun damage. Turning your plants a quarter turn once a month will keep them from leaning.
Humidity
Standard home humidity levels are fine for rubber trees. Consider adding a humidifier if your home is super dry.
Temperature
Normal indoor temperatures suit rubber trees well. Just keep these plants away from drafty windows and air conditioning or heating units, and abrupt temperature changes.
Fertilizer
Because they grow quickly, rubber trees require a bit more fertilizer than some houseplants. To keep them happy, feed rubber trees from spring through summer with an organic liquid fertilizer diluted to half strength. Fertilizer applications usually need to be applied once every 2 to 4 weeks, but this can vary depending on the product you’re using.
Toxicity
Rubber plants contain a milky sap that can irritate skin, so it’s wise to wear gloves when pruning or repotting. Ingesting leaves or sap can also cause mild stomach upset in humans or pets, so keep curious hands and paws away from your plant. Aside from this caution, rubber plants are generally safe to have in homes with pets, as they aren’t highly toxic.
Types
Most rubber trees grow to about 6 feet high indoors and produce glossy, deep green leaves that are encased in pink leaf sheaths when they first emerge. But if you’re looking for a bit of variety, there are a few more unique types to try!
- ‘Yellow Gem’: This variegated rubber tree option has bright, golden yellow leaf margins surrounding splotchy green centers.
- ‘Tineke’: One of the most colorful rubber trees you can find, ‘Tineke’ has variegated leaves in shades of deep green, creamy white, and bright pink.
- ‘Congesta’: A fine choice for small spaces, ‘Congesta’ is a dwarf rubber tree option that usually stays under 4 feet high.

Propagation
Rubber trees can be propagated by air layering or stem cuttings. I personally use the stem cutting method and propagate my plants in soil as water propagation often causes rubber plants to rot before they root.
- Take a 6-inch long cutting from the end of a healthy rubber tree branch in spring or summer.
- Make your pruning cut at a leaf node and use a sharp, sterilized knife or pair of pruners to limit plant damage.
- Remove the lower leaves on the cut stem and dip the stem end in rooting hormone if you have some.
- Plant the stem end 1 to 2 inches deep in a pot filled with pre-moistened potting or seed starting mix.
- Move the cutting into bright, indirect light, cover the plant and pot with clear plastic to boost humidity, and water the cutting enough to keep the soil evenly moist.
- Rubber plant cuttings should root in about 3 weeks. Then, care for them just like the parent plant!
Seasonal Care
I move my rubber trees outdoors in summer when temperatures are above 50°F so my plants can take advantage of the extra sun. To avoid sunburnt leaves, I transition my plants out slowly and only keep them in shady corners of my yard for the season. Before temperatures dip below 50°F, I check my plants over carefully for bugs, spray them down preventatively with an organic soap spray, and then bring them back indoors.
Whether you move rubber trees outside during summer or keep them indoors year-round is up to you. Care requirements don’t vary much for these plants through the seasons, but you’ll want to water them less in fall and winter, and withhold all fertilizer when they aren’t actively growing.
