9 Tips on How to Care for Rubber Tree Indoors
1. Your Rubber Tree is Happiest in Bright Indirect Light
Rubber Trees will thrive in a bright area with indirect sunlight. Too much shade will result in poor growth. You can filter direct sunlight using sheer blinds or curtains. Filter intense afternoon sun. Direct sun from south facing windows will also need to be filtered.
2. Moderate Water is Best for Rubber Tree
Water your Rubber Plant when the soil feels dry. The best way to tell when it is time to water your Rubber Plant is to feel the soil. Stick your finger in the soil 1 inch deep. If the soil feels dry, it’s time to water your Rubber Plant. If the soil is wet, then don’t water your Rubber Plant.
Also take into account the environment, if it’s in the middle of summer you can probably water your Rubber Plant more frequently. If it’s during winter you can err on the side of less frequent watering.
3. Your Rubber Tree Needs Organic Soil
Rubber Tree needs a well-draining, organic potting mix. Only buy organic soil mix because the fertilizer is not as concentrated in organic soil. Non-organic soil should really only be used for outdoor plants.
4. Fertilize Your Rubber Tree
Rubber Tree should be fertilized once a month when it is actively growing. When it’s dormant, during the fall and winter, don’t fertilize.
5. Don’t forget to Repot Your Rubber Tree
Repot your Rubber Plant every year. Buy a large, heavy pot, around 4 inches larger (diameter) than the current pot. If you have a big Rubber Plant plant, get a heavy pot so it doesn’t topple over. Make sure you buy a pot that has drainage holes at the bottom so water doesn’t accumulate and cause root rot.
Know that repotting your Rubber Plant will make it grow larger. When it reaches the size you want it to be at, you should stop repotting your Rubber Plant.
6. Drainage is Essential for Rubber Tree
After watering your Rubber Plant and you see water draining out of the pot’s drainage holes, make sure you empty out the accumulated water in the saucer. Don’t let your Rubber Plant’s pot sit in this puddle of water. It will cause root rot!
7. Get the Temperature Right for Rubber Tree
Your Rubber Plant is a tropical plant. It needs to have daytime temperatures of 70F to 80 Fahrenheit (21-26C). Nighttime temperature should be at 60-70 Fahrenheit (15-21 C).
8. Keep Your Rubber Tree Dust Free
Dust accumulates on your Rubber Plant leaves overtime. The layer of dust decreases the plant’s ability to photosynthesize. Periodically wiping down the leaves of your Rubber Plant with a damp cloth will help keep your plant healthy. You can also use a duster or dry duster cloth to wipe off the layer of dust on leaves.
9. Humidity is Vital for Your Rubber Tree
Your Rubber Tree is a tropical plant that thrives in humid conditions. Indoor air can be drying. Make sure you do your best to increase indoor humidity. You can do this by spraying your Rubber Plant with water twice a week. Turn on the humidifier. Keep Rubber Plant in a saucer filled with water. But make sure the pot is elevated with pot feet or pebbles so your Rubber Plant is not sitting directly on the water.
