Trimming and treating Adeniums in winter

Q: My desert rose below dropped leaves after I replanted it in a bigger pot. I noticed that one of the branches that had been pruned is black at the tip. Please let me know if the section of the branch that turned black needs to be cut. I also wasn't sure how often to water it since the leaves have all dropped. None of the other dessert roses have dropped their leaves but they are all younger plants. Any advice would be much appreciated.

A: Your plant looks healthy and vigorous overall. Dropping leaves after repotting, or shipping, especially at this time of the year, is normal in Adeniums. They are deciduous and stay leafless from Fall to Spring. Some individual specimens can go into dormancy sooner than others - all depends on conditions: temperature, light, exposure, etc. and individual plant's "clock".
The black spot on the cut branch may be a sign of a fungus as a result of excess water. You may carefully clean/rub it with a paper tower dipped in Hydrogen Peroxide (pharmacy grade). Then rinse with fresh water.
Keep the plant warm and in a dry spot. Once leaves are dropped, it doesn't need much water. Once a week watering is enough.

What you need for successful growing Adeniums

1) Adenium plants - from TopTropicals Endless selection of Adeniums. We have double flower, red, purple, yellow and even black flowers!
2) A small pot with excellent drainage is a must. Position the plant in a pot, size of root system.
3) Adenium soil mix. TopTropicals Adenium Soilless Mix. Use only well-drained soil.
4) Lots of light. Adeniums need lots of light for heavy flowering. However from our own experience, in super hot climates, they look healthier in filtered bright light. After initial planting, once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light.
5) Little water. Adeniums like a neutral to hard water. Acidic water tends to sour the soil too fast and may cause root rot. Water plants preferably in the early morning, and allow them to drink up throughout the day. Watering can be done daily to every few days. Do not water again until soil dries on surface. Never allow your plants to sit in a saucer of water, but don't let them to dry out too often - this causes adeniums to go into early dormancy. Adeniums do not like both over-watering or drying-out.
6) Fertilizer. To make your plant develop a large swollen base/trunk, you'll need a good quality fertilizer. Use slow-release granulated fertilizer for overall plant health, and liquid water soluble fertilizer for swelling up trunks that is also used to increase flowering. It shouldn't be too high in nitrogen, the middle number should be the highest (similar to 10-50-10). Never apply fertilizer directly on roots and do not liquid feed when a plant is thirsty: always water first slightly to avoid root burn and leaf drop. Do not wet leaves.
7) SuperFood micro-elements. Besides macro-nutrients provided by fertilizer, Adenium needs micro-elements for balanced development of root system and especially caudex: Sunshine-SuperFood.
8) SUNSHINE-BC. Spray leaves with SUNSHINE-BC once a month to encourage young growth, profuse flowering and large caudex.
9) Growing caudex. There is a secret how to create a large swollen caudex: raise the plant a bit every time you re-pot it, so that the upper part of roots will be a little exposed. The plant will form more roots that will go down.
