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.

Growing Jackfruit in a pot

Q: I have a young jackfruit tree, and I wanted to know, is a 25 pot enough for an adult tree?

A: 25 to 50 gal should be eventually a good size pot for growing a Jackfruit tree. Keep in mind the following:
1. Start with a smaller container, only slightly bigger than the root system. Do not plant directly into a large container, this may create a risk for root rot.
2. Step up the tree in a bigger container every year as it grows bigger. With every repotting, trim both branches and roots to compact the plant and to encourage branching out.
3. Jackfruit trees should be kept pruned under 6-7 ft in pots and 10-12 ft in the ground. This makes healthy fruit production more efficient and keeps fruit at the base of the tree.

Information on new exotic fruit variety:
Artocarpus x integer (Jackfruit x Chempedak), Cheena cv. TopTropicals

FRESH SEEDS! Grow exotic Chempedak from seeds and you will have the trees for only $1 each!

Check out a short video of the opened fruit.

Cheena is a natural hybrid between jackfruit and chempedak. Comes true from seed. This highly recommended variety has grown in TopTropicals garden from a seedling of Cheena (Jackfruit x Chempedak) that fruited within 3 years from planting. The fruit (20-25" size) is probably the best we ever tasted! It is super sweet, crunchy and has a rich, pleasant, excellent flavor. It has very little latex which makes it easy to handle when cutting up. The tree produces at the very base of the trunk, so you can prune it as short as you want. Our tree survived light frosts as well as 48 hours of 3ft flooding, with no damage!
The tree has an open, low and spreading growth habit and can be maintained at a height and spread of 8 ft with annual pruning. It is very easy to grow and is not as cold hardy as we thought for a Jackfruit x Chempedak types of plants. The only two recommendations are - good fertilу soil with a high content of compost and regular watering.
Cheena is a consistent producer. The fruit is up to 5 lbs, long, narrow and uniform in size and shape. The skin is green, with blunt spines that yellow and open slightly upon maturity.

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.

Kwai Muk: the Ugly Delicious Fruit

Q: I have been hunting for a rare and exotic edible to grow on my property here in South Florida for some time now. I found an interesting tree called Kwai Muk while browsing your website. I do not have a lot of space left to plant but this tree seems to be smaller in size and also somewhat cold and wind tolerant which is a bonus as far as I am concerned. It also sounds like the fruit is exceptional. I would love to grow one. It is similar to Jackfruit?

A: ...The piece de resistance of Kwai Muk is the excellent fruit it produces. Some people seem to think it is some of the weirdest looking fruit out there! This may be true, but what it lacks in appearance, it certainly makes up for in taste. It is called sometimes "the ugliest and yet the best tasting fruit". The creamy pulp is absolutely delicious and mostly eaten fresh. I have heard people say the flavor reminds them of mango, apricot, jackfruit, fig, quava and strawberry. Sweet and tangy loveliness with a hint of sherbet. The fruit looks like mini jackfruit on the inside but is about the size of a fig. The flesh inside also closely resembles jackfruit....

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.
