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.

How to get Strophanthus tree to bloom?

Q: I purchased from you three of these plants - Strophanthus bovinii and I wonder if you could help me. The plants are out of control growing large limbs to the sides and I would like it to grow more upright. Is this possible? Second, it does not flower. What type of fertilizer should I use and how often? How about the watering schedule? I have them in an eastern exposure but possibly they are not getting enough sun? Right in front of them, there is a large tree outside the curb of my house. What should I do about that?

A: Strophanthus bovinii - Wood shaving flower, is quite a unique plant that is very rare in cultivation, this is why very little information is available on its cultivation due to limited experience among gardeners. We have had this plant in our garden for over 12 years and this is what we can advise.
In the nature (Madagascar) it supposedly grows into a large tree, however, from our experience, it tends to be rather bushy, umbrella-like large shrub. Yes, you can train it into a tree by trimming branches growing side-wise, and by removing lower branches. The best time for pruning is early spring when the tree starts new growth and re-leafs (it is semi-deciduous). As far as flowering, the plant is very particular about blooming season, with profuse flowering in Summer (here in SW Florida), however it may produce more flowers sporadically throughout the year.
It thrives in full sun but will tolerate bright filtered light. If a large tree is shading it too much, try to trim some limbs of that large tree to allow more light. Water needs of Strophanthus bovinii are very moderate, so you can rely on your sprinkler system or water once a week for established plants.
You should use 2 types of fertilizers - slow release (once a month) and water-soluble bloom booster (frequent applications are safe):

Perfecting a Mango Tree

Q: I recently purchased a Mangifera indica - Coconut Cream Mango from you and would like to know if it is possible to keep this in a large pot rather than putting it in the ground. If so, I have a few questions:
1. How large would you expect this variety to get?
2. What are the ideal growing conditions? Full sun, partial sun, etc...?
3. What is the ideal soil?
4. Any specific watering directions for ideal growth?

A: Coconut Cream mango tree has a moderate growth. We've planted one in our garden 4 years ago and it is still under 10 ft tall. This variety should be well suitable for container culture.
1. Keep the branches trimmed after fruiting is over. Mango trees can be grown in 15 to 25 gal containers and can be trimmed under 7-8 ft high.
2. All mango trees need full sun, the more sun the better.
3. Mango needs very well draining soil, ideally with lots of bark and perlite. We recommend our professional soilless mix or a similar formula.
4. Mango trees hate wet feet, and prefer to stay on a dry side: make sure soil in a pot doesn't stay wet; allow it to dry a little between the waterings.
Remember to apply Mango Food fertilizer during warm season for vigorous growth and heavy crop!

Dwarf Red Ginger - more than just a pretty face

Q: I've just recently moved to Florida from North Carolina. I don't know much about tropical plants. Can you perhaps suggest an easy and pretty flowering plant for a beginner which I can plant around my garden pond for a tropical feeling?

A: For adding that tropical look to your garden, few plants beat beautiful ginger! Alpinia purpurata, the Dwarf Red Cone Ginger with its bright red floral spikes and lush, lance-shaped foliage is no exception. This striking perennial will add a tropical effect to your garden that will definitely take your breath away.
The Dwarf Red Cone grows between 3 and 4 feet tall and blooms 8-9 months of the year! The blooms will hold on the plant for up to 3 weeks! It makes a very attractive and distinctive backdrop for other plants.
Red Cone Ginger likes partial shade and moist, humid conditions, but will tolerate full sun. It is fast growing, easy to grow and resistant to disease, heat, and insects. The plant is a wonderful accent in a garden and works well as a focal point specimen, show-stopping when planted around garden ponds or near entryways. This ginger also works very well in containers and planters. Either in mass plantings or smaller groups, all gingers add tropical flair which never disappoints.
In addition, the beautiful flower spikes make for great, long-lasting cut flowers and is an interesting addition to bouquets.
An added bonus? Dwarf Red Ginger is super easy to propagate. If stems are cut at the base and placed in water, they will generally root within a few weeks. Eventually, you can make a whole flowering hedge just from one plant!

Who does not like a plant that is non-fussy and not only beautiful but easy to grow? Dwarf Red Ginger is more than just a pretty face!
