Decorate Your Garden With Beautiful Adeniums

Adeniums are succulent perennials grown primarily in tropical areas. Adenium species range from shrubs to small trees having enlarged trunks and stems. However, some species are as tall as 15 feet. Extremely popular in Taiwan, Thailand, and Vietnam, Adeniums can be propagated by seeds as well as cuttings. Always go for plants grown from seeds because propagation of the plant from cuttings does not give you better results. These plants take a minimum of six months to grow from seedlings.

Growing Adeniums

  • Adeniums have earned the reputation for being slow-growing and need proper care to ensure a perfect bloom. Adeniums require well-aerated but moisture- retentive soil for better growth. The plant easily dies from root rot if planted in regular garden soil or potting mix. These extremely drought-resistant yet long-lived plants thrive well in sandy soils in hot regions and should be planted in a well-drained soil. If grown in regions experiencing occasional frost, Adeniums should be grown in a warm, sheltered position.
  • Heavy watering is harmful for Adeniums during dormant phase, which can cause stunted growth due to chronic water stress. In hot weather, water Adeniums like tomato plants and like rot-prone, delicate cactus during winters. In the dormant phase during winters, avoid too much watering, as the plants are vulnerable to root rot if watered too frequently in cool season. Chronic waterlogging in any season is extremely harmful to the plant. You can prevent rotting problems by using a well-drained
    potting medium.
  • All Adenium species need full sun and high light intensity. However, the plants should be kept in the same direction throughout the summer season so as to avoid burning the stem sides that have already been shaded in the sun. Autumn poses the greatest risk to Adeniums and is regarded as the most hazardous time for the plant, as the sun is low but still quite strong. This can harm the base of young Adeniums. It is necessary to protect young plants from the sun of dry climates as long as these are less than three inches thick.
  • Adenium plants thrive well in moderately hot climates, with moderate to high humidity and temperatures ranging from 85 to 95F. However, temperatures constantly above 100F are hazardous for plant growth and flowering.
  • Adeniums thrive well if you follow the practice of generous fertilizing. Use a slow-release fertilizer during the growing season, including an equal proportion of micronutrients and a considerable nitrogen concentration. These plants require high nitrogen during the growing and flowering time. Contrarily, inadequate watering and improper feeding can slow the growth of Adeniums.
  • Adenium plants need vast root space to ensure fast growth. All species grow well in pots; however, as these become root-bound quickly, repotting the plant frequently is necessary so as to allow the plant to attain their full size. Overcrowded roots can stunt the plant growth.
  • Prune Adeniums before the monsoon to avoid root rot, as excessive water and moisture during the season can cause rot. However, if Adeniums still rot, prune off the diseased parts, leaving no stub. Remain extra careful while pruning Adeniums and check that the cut is white. If you find black discoloration, it means the cut area is diseased and that further pruning is required. Further cut the stem at a lower level until the white stem section appears. Tall plants should be pruned annually or once every two years so as to remove spider mites and mealy bugs, two of the most common pests affecting the plant.
  • Adeniums do well if re-potted annually or biannually. Remove the old media from the pot while re-potting, especially if it looks degraded. In case of mature plants, the large tuberous rootstock makes transplantation of mature plants difficult. In such a case, when transplanting, prune some of the roots where they interconnect with the main caudex. It is better to re-pot Adeniums in spring, when fresh growth has started. During this season, roots grow rapidly, which supports explosive shoot growth. If you find small shoots at each stem end, remove all leaving a few shoots from each main branch so as to ensure copious plant growth.
