As long as they are in the proper circumstances for growth, fresh stem cuttings will begin to root in 4–6 weeks after being propagated. It only takes two weeks for established plants to regrow lush, vivid leaves after being stripped of them by grazing.
Is elephant bushes’ growth sluggish?
The African elephant bush got its name because elephants consume it frequently. Warm-weather plants like the rainbow portulacaria can be grown in USDA plant hardiness zones 10 and 11. It is typically grown indoors because of this.
Variegated elephant bush can grow up to 20 feet tall in its natural habitat (6 m.). However, in the home garden, this slow-growing plant is typically kept to a height of 10 feet (3 meters) or less. By cultivating rainbow elephant bushes in a compact container, you can further manage the size.
What size can an elephant bush reach?
In habitats where it is a preferred meal of elephants, elephant bush plants can grow to heights of 6 to 20 feet (2 to 6 meters). It is considerably more likely to only grow a few feet (about one meter) tall inside the house. The bush has small, soft green leaves on thick, succulent brown stalks that resemble miniature jade plants.
Elephant bush houseplants do well in indoor environments like those found in homes. Warm temperatures and bright light are necessary for portulacaria care. The bush produces tiny pink blooms clustered at the terminals of the branches after a wintertime dormancy period.
Sunlight Requirements: Light Shade to Full Sun
Portulacaria Afra can withstand full sun and requires a lot of bright light. The plant may initially need to adjust to full sun. Extreme heat may cause mild sunburn, but other from that, these plants can withstand the heat.
Indoor Lighting
Provide the plant with the strongest light imaginable if you’re caring for it inside. The best window to use is one that faces south, though east or west facing windows will also work. Before you discover the ideal location, you might need to move the plant a few times. The ideal amount of light for the plant is between 5 and 6 hours.
Consider utilizing a growlight to provide your plants with the lighting they require to grow properly if your area does not receive enough sunlight or your home has insufficient lighting, especially during the long, dark winter months. Here are some suggestions for growlights that might be useful.
Check out my post on “Proper Lighting for Succulents Indoors” for more information on this subject and to get some useful advice.
Outdoor Sunlight Requirements
Elephant Bush, or Portulacaria Afra, thrives in locations with lots of sunlight. Although they can handle both partial and full sun, they favor bright, filtered light. They must become accustomed to the full sun otherwise the leaves would burn.
Place in a bright, sunny area if maintained outside. To reduce the risk of sunburn or other sun damage, it is preferable to acclimatize the plant first before bringing it outdoors or increasing the quantity of sunshine it receives. Increase the amount of sunshine it gets gradually until it is used to the sun completely. Remember that even if a plant is accustomed to full sun, it is still possible for it to get sunburned during a heat wave or other periods of extreme heat.
In Northern California, where summertime temperatures can exceed 100F or 37.8C, sunshades are a genuine lifesaver for my plants. Here are a few sunshades and sun protection ideas I have.
Please see my post “How Much Sunshine Do Succulents Need Outdoors? for more information and handy tips on outdoor sunlight requirements.
Frost Tolerance
As long as they are not sustained for an extended period of time, Portulacaria Afra can withstand light frost and freezing temperatures. You can leave the plant outside all year long and even plant it in the ground if you reside in one of USDA hardiness zones 9 through 11. The ideal approach to cultivate these plants is in containers, especially if your area experiences harsh winters. In winter or when snow or frost is predicted, you can then bring them inside.
There are methods for shielding plants from frost or freezing temperatures if you are unable to bring them inside for any reason. To assist them through the harsh winter, you can use frost cloths or tiny greenhouses. Here are a few of my suggestions for preventing frost.
How old is an elephant bush?
Sun burn is caused by receiving too much sunlight, and its symptoms usually include crispy or browning leaves, dry leaf edges, sunken leaves, or stunted growth. Although too much light will lead to overwatering problems, too little light will also harm the plant. Reduce the quantity of sun exposure significantly if yours has fallen short of this, and always be cautious of environmental shock (when two locations offer too different growing conditions). Eliminate some of the harmed leaves and slightly raise the water level.
On the other hand, specimens kept in overly dark conditions with extended soil wetness frequently get root rot. Rapid leaf browning, moldy soil, stunted development, and a rotten brown base are all symptoms. Examine the plant’s health below the compost line after removing it from the pot. You’re okay to go if the roots have a yellow tint, but you need to take fast action with brown and mushy roots. On this link, you may learn more about treating root rot.
Regularly clean the leaves. Although it’s not a big deal, a buildup of dust particles might clog the plant’s pores and reduce its ability to absorb light. In order to maintain low levels and enhance growing circumstances, rinse the topsides of the leaves once every month.
Never let the temperature drop below 10°C (50°F), since this may do irreparable harm to things like yellow foliage and decreased health. Never cut through softened yellow or brown growth when this happens; instead, remove the badly impacted sections and quickly correct the growing environment. Because of its slow growth, rehabilitation might take many months. To shorten this time, make sure to give the plant a stable place with improved growing conditions.
Several different factors could be the cause of unsuccessful leaf-cuttings. Elephant Bushes are best propagated in the spring when they are at their busiest, thus cuttings obtained then may root considerably more slowly and may even die in the interim. Check the surroundings to see if there is enough light to read a newspaper. If not, increase the amount of indirect sunlight it receives to improve the growing conditions. Never place the cuttings in the sun; doing so will cause severe dehydration and almost certainly death. Its success will also be significantly influenced by its overall size. There must be no obvious signs of damage or cuts, and the total height must be greater than 8cm. Smaller specimens won’t root properly since the stems have less energy stored in them. If the leaves are grown hydroponically, the water should be changed every week to reduce the chance of germs growing in the container. In order to prevent nasty infections from spreading to unaffected specimens, yellow or brown parts that are progressively withering away must also be eliminated. Those who are submerged immediately in cold water will also display signs of distress. Make sure to use a well-draining potting mix with the appropriate quantity of sand and grit if you’re interested in propagating via soil. The likelihood of roots developing will be drastically reduced if they are planted too deeply or in soil that is too wet.
Despite its slow rate of growth, Portulacaria can be easily shaped into a bonsai after years of cultivation.
Over ten species make up the genus Portulacaria, which has its natural distribution in Southern Africa. Its name is derived from the Latin word portula, which means “door” and relates to the fruit’s opening lid. Caria, which refers to the resemblance of the species Portulaca, means “related to.” The name of the species, afra, is a particular derogatory term for the continent of Africa. The sour-tasting leaf is a favorite food source for a variety of species, including elephants and ostriches. The species’ leaves, which are used in salads and soups, are also regarded as a local delicacy.
Temperature
H1b (Hardiness Zone 12) – Can be grown outside in the summer in a protected place with temperatures above 12C (54F), but is also acceptable to stay indoors. Avoid exposing this plant to direct sunlight if you decide to take it outside because it could cause sunburn and dehydration. Watch out for bugs frequently, especially while bringing it back inside.
Spread
if replanted every other year, up to 1.5m in width and 2m in height. The final height will take 5 to 10 years to reach, but with the correct care, it may live for 20 years or longer.
Pruning
To promote healthier growing conditions, remove yellow or decaying leaves as well as any plant detritus. Always use clean shears or tools when pruning to lower the risk of bacterial and fungal infections. Never cut through yellowed tissue as this could lead to severe harm from bacterial infections or other disorders. To avoid shocking the plant and resulting in decreased growth and a decline in health, always create clean incisions.
Propagation
Stem Cuttings (Easy): Cut a 5 cm (2 inch) chunk from the end of the stem using a pair of clean scissors. Use a component that is brand new, undamaged, and free of pests because unhealthy divisions are more likely to fail. To hasten the development of roots, remove the elder half of the leaves, leaving the lowest third of the stem naked. Purchase some “Cactus & Succulent” compost, then put the cutting’s base vertically into the ground to prevent soil from getting on the real leaf. Place the cutting in an area that is indirect, light, and has temps over 18C. (64F). Once there are indications of new foliar development, remove the bag and treat the plant as an adult specimen because the roots will grow first.
Flowers
Mid-summer, mature specimens can produce tiny clusters of 2mm-wide, pink or white-scented blooms that can persist up to a few weeks. Due to the unfavorable growing circumstances and lengthy maturation period, elephant bushes won’t bloom in a home environment for many years.
Repotting
Every two to three years, repot your plants in the spring using ‘Cactus & Succulent’ potting soil and the next-largest pot with drainage. Checking the health of the roots and, if desired, propagation can also be done now. Check the lower part of the root ball for any discolored or damaged root caps as Elephant Bushes are susceptible to root rot. If so, use clean tools to remove the damaged parts and gradually reduce the irrigations. For additional information on how to perform the ideal transplant, go on this page.
If you’d want a customized tutorial on repotting your houseplant, schedule a 1-on-1 video session with Joe Bagley. The appropriate branded-compost and pot size will be suggested, and a live video call will be made while you transplant the specimen to provide step-by-step instructions and address any other questions.
How frequently should an elephant bush be watered?
The Portulacaria Afra needs a succulent soil mixture that drains well. There shouldn’t be too much moisture in the mixture.
Use a pot with holes for drainage. Perlite is another option for your potting soil mixture. The correct airflow in the soil is made possible by perlite, hastening the drying process.
What are the Sunlight Requirements of the Elephant Bush?
Place your elephant bush where it receives some direct sunlight and some partial shade throughout the day.
The Portulacaria Afra or Elephant Bush requires at least six hours per day of direct sunlight. Avoid spending a lot of time in direct sunlight. Otherwise, keep in some shade.
Heat intolerance exists in the elephant bush in miniature. It might be more prone to sunburn than its larger sibling.
What is the Humidity Requirement of the Elephant Bush?
A succulent is not required by the elephant bush for humidity. It does well in humidity at room temperature.
The portulacaria afra needs average indoor humidity. Spraying it with water to wet it is not recommended because it can result in unreasonably high humidity levels.
How Should I Water the Elephant Bush?
Elephant bushes don’t store a lot of water because their leaves are thin. In the summer, it has to be watered once a week. In the winter or during the milder summer months, water it every 1.5 weeks.
Simply because the Portulacaria has thin leaves, don’t overwater it!
How to Fertilize the Elephant Bush?
Little fertilizer is required by the Elephant Bush. You can use the one designed for cacti. Give a drop each month from spring to fall, when the plants are actively growing.
In the winter, succulents scarcely need to be consumed. That is more akin to their free time. When it’s cold, water with fertilizer will make them unhappy!
How to Prune the Elephant Bush?
The Elephant Bush can be pruned for shape in addition to removing dead sections!
Before pruning, the Portulacaria Afra needs to be dry. Before you start pruning, make sure your knife is clean and sharp. Offsets and dead stems must be immediately cut.
The Elephant Bush plant can also be styled by pruning. Make cuts in the desired shapes for your Portulacaria Afra. You can even create a Bonsai tree in small size if you like!
You’ll need water and bleach. Pour some bleach into a 90 percent water solution. Before you cut the plant, thoroughly rinse your blade or knife in the mixture.
How to Repot the Elephant Bush?
The Elephant Bush takes a while to mature. Only when the plant outgrows its pot will you need to repot it. You shouldn’t water the Portulacaria Afra for at least seven days after repotting.
