Growing desert roses
Q: I purchased a Desert Rose and planted it in Adenium mix. I keep it in full sun with once a week watering assuming this is a desert plant that likes lots of sun. Some leaves turned yellow and now I am not sure should I move it into shade or need to water more? Or maybe fertilize with something?
A: Desert Rose - Adenium, unlike cacti and other succulents, prefers filtered light. It can grow in full sun but leaves look healthier in light shade. Watering must be very moderate, however don't let soil harden like a rock: water again right after the soil gets dry. We suggest to use special Adenium Mix. Cactus mix may work well, as well as regular potting mix, in which case it is recommended to add a bit of limestone (we simply put sea shells on top of the pot - it looks very pretty!) - because adeniums prefer slightly alkaline soil (while most of tropical plants like acidic soils). If leaves turn yellow, this may be a sign of underwatering. Use water soluable fertilizer with high phosphate as foliage spray, and only on healthy plants, according to label dosage. It helps both caudex growth and flowering. Make sure to avoid fertilizer contact with a caudex.

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.

Overwintering Adeniums outside of tropics
Q: We bought several adenium plants from you. We are moving to the Denver area of Colorado. How can we make sure the plants survive? Should we use a green house?
A: Adeniums are perfect container plants, and house plants. They can be easily grown outside of tropical climate. During winter, Adeniums drop leaves and go into dormancy which makes it easy to keep these plants in a dormant stage in a warm location of your house, or possibly even in well-lit spot of garage (with a window), with temperatures above 50-60F.
Here in South Florida, during time of cold, when chances of freeze are high, we move our own Adenium collection into lanai, with plastic sheet protection around lanai.
In colder climates, Adeniums can be kept indoors as house plants during winter. There are some requirements/tips for you:
- Temperature. Move Adeniums indoors when temperature starts dropping below 45F.
- SUNSHINE. Use SUNSHINE boosters to improve cold resistance of Adeniums, and essure healthy plant throughout winter. SUNSHINE-BC formula is specifically designed for plants with caudex, and bonsai.
- Water. Reduce watering to minimum, especially when plants drop leaves - this means they went into dormancy. Once a week light watering is enough. Water very carefully during cooler months. When it is hot (85-100F), excessive water usually won't harm adeniums: it will be partially used by a plant, and partially will evaporate. Especially be careful with water when temperatures drop below 65F - then tropical plants simply stop growing process and go dormant. Once adeniums start losing leaves, this is a sign to reduce watering to once a week to once a month, and in very small quantity (couple tablespoons per pot).
- Light. Bright light is not necessary, but do not keep them in dark either, even if all leaves dropped. Good light is necessary to maintain healthy stems and caudex. Keep in mind, the less light, the less watering too. Ideal spot is a windowsill, however if your space is limited and all windows occupied by other "leafy" plants, location close to window will be enough as long as watering is reduced, to avoid rot. We keep our big collection specimens on a roofed porch during winter, where level of light is very low. Last winter we haven't lost a single plant due to low light. They take shade pretty well considering minimum or no water. However bright light is always better - it creates healthier environment for a plant. We all know about space limitations for our large collections, especially in winter. So if you can afford a bright spot for adenium during winter - the plant will be lucky!
- Soil. Use only well drained mix with much higher content of perlite than you would use for most tropical plants. For adeniums, we use mix with 30-40% of perlite in it, while regular mix has 10-15%. Adeniums like alkaline soil, unlike most of tropical plants (hard to say what else likes alkaline... Ficus for sure!). This means, regular mix with high content of peat moss may cause root rot. To increase alkalinity, you may add dolomite. Here in Florida where we have natural supply of shell rock handy, it is easy to add some shell to a potting mix (shell sand, rather than quartz sand). We always add a few large shells on top of a pots with a big specimen. Besides increasing soil pH (making it more alkaline), shells look very decorative.
- Fertilizer. No fertilizer until Spring when plants start showing new growth and new leaves.
- Move your Adeniums outside in Spring, when chances of freeze are zero. More sunlight and air circulation is beneficial for breaking the dormancy and providing plants with a quick growth start.

Planting instructions for bare-rooted succulent plants
Q: I would like to order a few Adeniums from your selection. You website says "shipped barerooted". What do I need to know about potting these plants before I order?
A: Adeniums do not require much soil; large 4-5" wide caudex plant can be grown in 1 gal pot. After unpacking the plants, position it in a pot, size of root system. Use only well-drained soil with high content of perlite and/or sand. Cactus mix can be used too, although we recommend using our special TopTropicals professional soilless potting mix. Water once and keep in warm (75-80F) place in filtered light. Do not water again until soil dries on surface. Once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light. Then you can start fertilizing it. You may place shells and lime rocks on top of adenium planting, as these plants benefit from slightly alkaline soils.

Desert rose winter care
Q: I purchased several packets of desert rose seeds last year. I now have 45 very healthy seedlings some of them in bud. Almost all of my seeds grew but I lost most of them when I rook them in during winter. I did not water them for a month , kept them in their pots and set them by the window. they either dried up and died or rotted and died. I noticed when you send me grafted specimens that you bareroot them. Is this a better way to keep them inside in winter, bareroot? I hate to lose these plants come winter time. Pls advise me. I live in Houston, Tx. where we get temps below 40 degrees and sometime a day or more of freezing temps.
A: Thank you for your question. Rot is pretty common problem with Desert Roses. We monitor our Adeniums closely and have a special set up of watering environment and schedule, in dedicated greenhouses just for them. Nevertheless - every now and then we see a rotten caudex and can't help it to say "oops! over-watered!" These plants are very sensitive to environment changes, especially when it comes to a combination of water and temperature. These are a few tips that should help you to reduce risk of plant loss to a minimum:
1) Use only well drained mix with much higher content of perlite than you would use for most tropical plants. For adeniums, we use mix with 30-40% of perlite in it, while regular mix has 10-15%.
2) Adeniums like alkaline soil, unlike most of tropical plants (hard to say what else likes alkaline... Ficus for sure!). This means, regular mix with high content of peat moss may cause root rot.

Once adeniums start losing leaves, this is a sign to reduce watering to once a week to once a month, and in very small quantity (couple tablespoons per pot).
4) We do not bareroot adeniums for winter storage. They are not bulbs. Barerooting of this plant is recommended only during shipping. Adeniums can stay without soil for up to a week without hardly any stress, sometimes even longer.
5) We keep our big collection specimens on a roofed porch during winter, where level of light is very low. Last winter we haven't lost a single plant due to low light. They take shade pretty well considering minimum or no water. However bright light is always better - it creates healthier environment for a plant. We all know about space limitations for our large collections, especially in winter. So if you can afford a bright spot for adenium during winter - the plant will be lucky!

Meet PeopleCats of TopTropicals. Cat of the Day: Sonya, the Co-Author
In our previous newsletter, you met our editor/photographer tandem - Tilda & Marina. Today we introduce our columnist assistant - Sonya. For the past decade, this True Norwegian Forest Cat has been a great helper and inspirational co-author for Alexandra, TopTropicals website writer and social media blogger.
Alex has been with TopTropicals since Day One (2003). In 2011, she got Sonya, a 3-month old kitten that someone kicked out: at that young age she already had quite a temper of a real Wild Cat. No one wanted to adopt her and Sonya was doomed to suffer a street life... So Alex invited her in the house... and it took her many months to teach Sonya some good manners! And Sonya turned into a beautiful and affectionate Purrrson as well as became the Boss in the house (what a surprise, duh) and Alexandra's dearest life companion. Sonya also discovered her talent in writing plant stories for TopTropicals, sitting on Alex's shoulder and whispering into her ear while she is typing Sonya's horticultural tips. And when Alex stares at monitors for more than 5 hours, Sonya lays on her keyboard saying: "Now get up and get some stretch lady! Let's go re-pot some plants for a change!"
We will be following up on Sonya's creative work, and you will hear from her again soon...

Adenium: a Rose by any Other Name
New
article by Jane Jordan.
"...The famous quote is often used to imply that the names
of things do not affect what they really are, in the case
of The Desert Rose (Adenium obesum) it is not a rose at
all, rather a succulent that thrives in hot, dry and sunny
conditions. These spectacular plants have no relation to
the rose family, they are a species of flowering plant
from the dogbane family, Apocynaceae. The naming of this
plant is partly correct as they originate in sub-Saharan
Africa and the Arabian Peninsula, where they can grow into
large trees with huge swollen trunks..."

Healthy Plant Food
Q&A from Mr Booster
Plant food for a Star Fruit
Q: I have 2 Starfruit plants from you. One on the left is B10 has a lot of flowers but no fruit is developing. On the rite is Kenjeng. This one has no flowers at all. Both plants are growing very well. Plenty of sun and water. I am located in Boynton Beach Florida. So what to do?
A: Your trees on the pictures look very healthy, congratulations
with a great care!
Starfruit, as well as other grafted fruit trees (like mango, avocado, etc)
usually flower/fruit easily and readily while in pots in the nursery.
Sometimes, once planted in the ground, they may reduce flowering or even stop
flowering. What happened?
The answer is simple. In pots, we fertilize them on regular basis. In our
nursery, we have fertilizer injector inline with irrigation system that dozes
plant food with EVERY watering. In other nurseries, they may also use
slow-release fertilizers, but it is still a regular routine to provide plant food to
potted plants.
In the ground, especially in Florida poor soils, fruit trees may stop
flowering or delay fruiting due to lack of nutrients, or dis-balance of elements
in the ground. Without fertilizer, a tree may take extra time to develop
bigger root system to reach out for necessary elements, and eventually will start
fruiting anyway.
But we want it to fruit soon! The only way to fix the problem is to provide
fertilizer on regular basis for a young tree. It is especially important
during hot summer months when plant metabolism is fast due to high temperatures,
plus nutrients may get washed away with frequent summer rains (like we have
in Florida) even if you've added some fertilizer at time of planting.
You can use smart release fertilizer once a month during hot season,
this one or similar:
Mango-Food - Smart Release Fruit Tree Booster.
But the most effective way to get a tropical tree to flowering and
fruiting, is frequent applications of liquid fertilizer. We use Sunshine Boosters
with every watering on our plants. They work great even on hard cases and
weak plants, and you see the difference in a matter of weeks, sometimes even
days.
We recommend the following fertilizer that contains all necessary elements
for young fruit trees:
SUNSHINE C-Cibus - Crop Nutrition Booster
SUNSHINE C-Cibus - Crop Nutrition Booster from Garden Series, or Combo Total Feed Collection - all nutrients in just one bottle, for fruit trees and edibles.
