American Rubber Plant:
Outdoor Growing Tips for a Beautiful Garden

Updated: April 21, 2023

The American Rubber Plant, also known as the Ficus elastica, is a popular houseplant due to its attractive foliage and easy care requirements. However, it can also be grown outdoors in certain climates to add a touch of tropical beauty to your garden. Here are some tips for successfully growing an American Rubber Plant outdoors.

Climate Requirements

The American Rubber Plant thrives in warm and humid environments, making it perfect for areas with mild winters and hot summers. It can tolerate temperatures as low as 50°F (10°C) but prefers temperatures between 70°F (21°C) and 80°F (27°C). It is important to note that the plant cannot survive in freezing temperatures and should be brought indoors during the winter months in areas with cold climates.

Light Requirements

The American Rubber Plant requires bright, indirect sunlight when grown outdoors. It can tolerate some direct sunlight, but too much can cause the leaves to scorch. If your garden does not receive enough natural light, you can supplement with artificial grow lights.

Soil Requirements

The plant requires well-draining soil that is rich in organic matter. A mixture of peat moss, perlite, and sand is ideal for outdoor growing. Make sure the soil has good drainage to prevent root rot.

Watering Requirements

The American Rubber Plant requires consistent watering during the growing season. The soil should be kept moist but not waterlogged. Water deeply once a week, or more frequently during hot, dry weather. Reduce watering during the winter months when the plant is dormant.

Fertilizing Requirements

Fertilize the plant every two weeks during the growing season with a balanced fertilizer. Avoid fertilizing during the winter months when the plant is dormant.

Pruning Requirements

Prune your American Rubber Plant in early spring before new growth appears to encourage bushier growth. Remove any dead or damaged leaves and stems. You can also prune back any leggy branches to promote fuller growth.

Propagation Requirements

The American Rubber Plant can be propagated through stem cuttings taken in the spring or summer months. Cut a 4-6 inch stem from the parent plant and remove any leaves from the bottom half of the stem. Dip the cut end in rooting hormone and place it in moist potting soil. Keep the soil moist and warm until roots develop.
