The Ficus elastica commonly known as a Rubber plant is a large tropical plant. An upright houseplant on a sturdy stem they have large oval glossy leaves that vary by type. In this comprehensive guide, we'll walk you through everything you need to know to keep your Rubber plant healthy and thriving.
Rubber Plant Overview
Native to West Africa, these plants are loved for their beautiful big leaves with white stems that can grow to very large sizes. The Ficus Lyrata only naturally grows in western rainforests since this is the only place in the world that has the specific type of wasps needed to enable the plant's reproduction. Ideally, as long as the room is brightly lit, the Fiddle Leaf Fig would be the perfect addition to any room in your house.
Rubber plants can come in a variety of different colours, originating from the Himalayas, Malaysia, India and Eastern Asia. Popular varieties include Robusta, Tineke, Tricolour, Belize, Ruby, Melany, Abidjan. In the early 90’s the milky white sap was used to create rubber, which is where the plant got its common name. The plant can grow up to 3 metres when growing indoors and up to 30 in its native habitat! A popular choice among plant lovers not only for its looks but, unlike other types of ficus, this plant is very easy to care for
How to Look After a Ficus elastica (Rubber plant)
Light:
For best results pop in a spot where it will receive bright but indirect light, away from radiators or draughts. Avoid direct sunlight as this can scorch the leaves. Tolerant of lower light levels the Ficus elastica won't mind a slightly shadier spot, however if you find it is leaning to reach the light move to a brighter spot. Variegated varieties will lose variegation if not receiving enough light.
Temperature and Humidity:
Rubber plants prefer temperatures between 16°C - 24°C. Avoid exposing them to extreme temperature fluctuations or cold drafts. Rubber plants also prefer high-humidity environments. Mist around the leaves occasionally or place a tray of pebbles with water beneath the plant to increase humidity levels. Be mindful of drafts and avoid placing your Rubber plant near air-conditioning vents or heaters, as these can cause dryness.
Watering:
Rubber plants do not like to be sitting in wet soil, let it dry out half way before watering. Soil should feel dry if you push your finger into the soil. Watering should be reduced further in winter months to avoid root rot. Overwatering is the biggest reason for an unhealthy rubber plant and can cause yellowing leaves and leaf drop.
Fertilising:
Rubber plants enjoy a feed every 4 weeks during the growing season (spring-summer). As a general rule don't feed in winter or just after a repot. Follow the instructions on the fertiliser packaging for proper application. We sell an organic pure seaweed extract that when diluted is a great feed for plants including Ficus Elastica.
How to Re-pot a Rubber Plant
Ficus elastica will only need a repot when they get too big for their current pot and roots are coming out the bottom.. It is best to give the plant water 24 hours before the re-pot to avoid transplant shock. Spring is the best time to repot, as the plant is actively growing, try to avoid repotting plants in winter. Choose a pot that is one or two sizes larger than the current one, ensuring it has drainage holes at the bottom. Carefully remove the rubber plant from its current pot, gently loosening the root ball. Place it in the new pot and add fresh, well-draining potting mix around the roots. Gently press the soil to ensure the roots are bedded in. Avoid pressing too hard on the soil as this can cause it to compact. Water the plant thoroughly after repotting.
How to Propagate a Rubber plant
Propagating Rubber plants is an exciting way to grow new plants. Follow these steps:
- Choose a Healthy Stem: Select a stem with a few leaves and nodes (small bumps on the stem where a leaf emerges). Make sure you use gloves as the Sap can be an irritant to skin.
- Cut the Stem: Use a clean, sharp knife or scissors to cut just below a node. Ensure your cutting is at least 10 cm long and strip back any lower leaves.
- Rooting: Place the cutting in water or moist soil and place a clear plastic bag over the top. Place in a warm and bright indirect spot. Roots should develop within a few weeks.
- Transplant: Once your cutting has well-established roots, transplant it into a pot with the appropriate soil mix.
How to Prune a Rubber Plant
Pruning your Rubber plan helps maintain its shape and encourages healthy growth. Trim yellow or brown leaves, as well as leggy stems. Make clean cuts just above a leaf node.
How to Take a Cutting from a Rubber Plant
Taking cuttings for propagation follows a similar process as mentioned earlier. Ensure you choose a healthy stem, make a clean cut, and follow the propagation steps.
How Often Should I Water a Rubber Plant
Watering frequency depends on various factors like humidity, temperature, and pot size. As a general rule, check the soil and water when half the soil is dry. Water less in winter and more frequently during the growing season.
Why Are My Rubber Plant Leaves Going Yellow/Brown/Curling?
- Yellow Leaves: Yellowing leaves can result from overwatering, poor drainage, or too much direct sunlight. Adjust your watering and lighting conditions accordingly. If the leaves are wilting and yellowing it is most likely to be due to overwatering, check the roots for rot and re-pot if necessary.
- Brown Leaves: Brown edges or spots may indicate low humidity, underwatering, or direct sunlight. Increase humidity and adjust your watering routine. Too much warmth, for example, if the plant is next to a radiator, can cause brown leaves that dry up and fall off.
- Curling Leaves: Curling leaves can be a sign of underwatering, over-fertilization, or low humidity. Ensure proper watering and humidity levels.
How to Make a Rubber Plant Bushy
Encourage bushier growth by regularly pruning leggy stems, adding a bamboo cane can be used to help keep it upright. Ensure your Rubber plant has enough light, lack of light can cause this plant to become leggy.
Are Rubber Plants Poisonous to Cats and Dogs?
Yes, Rubber plants are toxic to humans and pets if ingested. Keep them out of
reach of children and pets to prevent accidental consumption. If ingested, seek medical attention immediately. The sap can also cause irritation to skin, make sure to wear gloves when handling.
With these expert tips, you're well-equipped to care for your Rubber plant! Happy Rubber Plant growing!
