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.

The Flower of Gold

By Onika Amell, tropical plant specialist

Q: I am concentrating on adding more fragrance to my garden. I've had great success growing gardenias and I have many different varieties, but their flowers are all white, and I would like to add some colors to my garden too. Are there any gardenias available in different colors? I live in Waipio Acres, Hawaii.

A: Meet the very rare and highly fragrant, tropical Gardenia tubifera Kula or Golden gardenia. Kula flowers change color as they mature, which is a unique feature! Kula flowers start out as cream, then change to yellow and finally to a beautiful gold. In addition to the spectacular flowers, this gardenia also has beautiful, leathery, deep green foliage.
This is a slow-growing and compact plant. Like all the other members in the Gardenia family, the Golden gardenia will do best in an acidic, well-drained, and fertile soil. It will appreciate a good deal of direct sunlight but will be very happy if provided with midday and afternoon shade. As with with gardenias, the more sunlight the more flowers.
It will eventually grow into a rounded shrub if left unpruned, but also can be trained into a small tree, maintainable to a height of under 7-8 feet. Blooms will appear from spring onward. Prune after flowering, this will encourage more flowers in a few months.
Gardeners living in colder areas, do not fret. Gardenias make perfect container plants and can be grown indoors in colder climates. Just be sure to provide high light when bringing them indoors.
The fragrance and changing colors of a Gardenia Kula is unforgettable. They are most fragrant near sunset and during early evening hours. Plant them near walks and patios where their lovely fragrance can be enjoyed.
This rare tropical Gardenia is sure to be a conversation piece in any garden. Great collector's plant!

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.
