This Ficus is a beautiful addition to any home and requires little maintenance.

Ficus Elastica Ruby Soil

Although it can be planted in a variety of potting mixtures, the variegated rubber plant prefers a loose, airy environment. This plant will have the rich, aerated soil it wants with the help of a combination of commercial mix with additional compost and perlite or vermiculite incorporations.

Rubber trees thrive in a potting soil that drains freely. It is the same with the Ficus elastica "Ruby."

This plant prefers a moist pot of soil with a pH range of 5.0 to 7.0. When kept indoors, especially, it is crucial that your plant's soil is nutrient-rich.

Generally, any indoor potting soil or soil for succulent plants will do. If the soil's drainage capabilities aren't quite right, they can easily be improved.

Ficus Elastica Ruby Fertilizer

In the spring and summer, feed your Ficus elastica "Ruby" once a month. Winter and autumn are not good times to fertilize because the plant is not actively growing and will not benefit from the fertilizer.

Throughout the warm growing seasons of spring and summer, your Ficus Elastica Ruby will appreciate being fed by a monthly application of a balanced liquid fertilizer.
