Desert rose has a slow growth rate, which for trees and shrubs generally means it gains less than 12 inches per year, often only reaching 14 inches after three years. Usually plants top out around 4 feet, though older ones may gain heights of 6 feet or more after decades of growth. If you have fresh adenium plant seeds and you are growing them in the right condition they will germinate in 5 to 7 days. yes, I have see some germinate in three days and some 2 weeks. But 95% will germinate in 5 to 7 days if the seeds are fresh. The desert rose can be grown from seeds or from stem cuttings. Let the stem cuttings dry out before planting. Plant them in the springtime and keep them in filtered sunlight until they begin to grow. The desert rose needs full sunlight and a temperature of 70 to 80 degrees Fahrenheit (21. 1 to 26. 7 degrees Celsius). When grown indoors, a desert rose can be 2ft-5ft tall and 1ft-3 ft wide. Desert rose plants have beautiful flowers and sparse small leaves. The 1″-2″ saucer shaped blooms are quite a conversation piece and can be red, pink, or white. The fat, bulbous trunk is partially or completely buried in the soil. Place a desert rose in your most sunny window where it can get direct sunlight for at least six hours per day. Water the plant regularly, about once a week; add water until you can see water running into the saucer.
For the desert rose, the growing season begins with few flowers in late winter followed by new foliage and continued flowering through summer and fall. The 2- to 3-inch-diameter flowers bloom in white, pink, purple and red. Desert rose benefits from a dormancy period in winter to allow the plant to rest and recharge.
Take a cutting from the tip of a branch. Allow the cutting to dry out for a day or two, then wet the end of the desert rose cutting and dip it in rooting hormone. Stick the cutting into a well draining growing medium like perlite or sand mixed with soil. Growing a desert rose from seeds or cuttings can be done.
Watering should be infrequent and light; as little once per month, and only moisten the top 1/4 to 1/2 of the soil. Adeniums respond well to pruning if it is done during the spring/summer growing season.
Feed indoor Adeniums every week during spring and summer, using a water-soluble fertilizer diluted to half strength. To encourage flowering, it may also help to use a phosphorus-rich fertilizer or bone meal.
Use a potting mix formulated for cacti or succulents or use regular potting soil mixed with equal parts perlite or sand to ensure the soil is well-draining. When repotting desert rose plants, make sure the soil is dry before gently removing the desert rose from its pot.
Steps Fill a pot or tray with a potting mixture of 50% peat moss and 50% sand. Put the seeds in holes 1 to 2 inches (2. 5 to 5. 1 cm) apart from one another. Place the pot or tray in a spot with 6 hours of indirect sunlight each day. Spray the growing medium with water every other day. Watch for sprouts within 7 days.
Fill a medium-size planting pot with a mixture of two parts sand, two parts peat moss and one part perlite. Place the cut end of the Adenium cutting about 2 inches (5 cm) deep in the soil medium. Water the Adenium cuttings every three days. The cutting should take root in two to six weeks.
Reaching Maturity. Desert rose has a slow growth rate, which for trees and shrubs generally means it gains less than 12 inches per year, often only reaching 14 inches after three years. Usually plants top out around 4 feet, though older ones may gain heights of 6 feet or more after decades of growth.
POTTED PLANTS Adenium prefer pots that allow their soil to dry rapidly and to allow room for their swollen base or caudex to expand. We recommend an 8 inch clay or ceramic pot that is no deeper than 4 inches, a typical cactus type pot.
Remove cold-damaged growth as soon as new growth emerges in late winter or early spring. (Tip: This is also a great time to repot your desert rose. ) Cut back long, lanky shoots to about the same length as other stems, using a pair of sharp, clean pruners. Prune any branches that rub or cross other branches.
The Adenium aka Desert Rose is included in the list of plants considered dangerously toxic to humans, dogs, cats, and horses. According to American Society for the Prevention of Cruelty to Animals (ASPCA), animals are instantly poisoned by the desert rose by ingesting a part of it or simply by licking the plant.
How to Grow Desert Rose Plants. The desert rose (Adenium obesum) is a striking plant with succulent stems and deep red flowers. The plant is deciduous in cooler winters, but it can be kept in leaf provided there is sufficient warmth and light water.
