Plumeria cold protection

Q: We have a purple-flowering plumeria which resides on our sunny deck during the warm months and then Winter vacations on our back porch where we can close the plastic film windows and where it stays above 50 degrees (overnite) until it can get moved outside again. We live in zone 8+ in South Carolina and I would love to plant it outside. Do you think if we ghost-covered it when alerted that we would have an overnite freeze, that it would survive being planted in the ground and recover to flower when warm? I don't believe the soil in our yard has ever frozen below the top 1/2 inch or so, and never for more than a few hours at a time. What do you think?

A: Plumerias are tropical plants, which means, they need frost-free environment. Even if the ground is frozen only on "the top ½" or so" - this may be enough to kill the plant. From our experience, plumerias can withstand a few hours of windchill frost (not frozen soil), but even if they survive, they may get some branches damage, and recovery may take so long that the plant may not even bloom the next year. So I wouldn't take that risk even with a ghost-cover cold protection. We have customers who grow tropical plants in the ground in colder areas, but they have greenhouse protection: this means, the soil is warm and the air temperature is maintained above 45-50F. For example, this Greenhouse in Virginia.

We recommend to continue growing your rare plumeria in container and move it inside when temperatures drop below 50F (recommended) and for sure when they drop below freezing. Plumeria can take a cold night (a few hours of upper 30's) as long as it is followed by a nice warm sunny afternoon with at least upper 50s. Otherwise, keep it indoors. The good news is, since plumerias are deciduous and have no leaves in winter, low light level won't affect the plant.
Just make sure to minimize watering and keep the plant on a dry side until it starts growing new leaves in Spring. You may continue fertilizing once a week with half-doze of Sunshine boosters - Sunshine TotalFeed. This will maintain the plant healthy and prepare for the blooming season in Spring.

Fragrance of Angel Hair Jasmine

Q: I got angel hair jasmine, it started flowering, but it does not have any smell. What can be done?

A: Jasminum pubescens - Angel Hair Jasmine has very fine fragrance. It is not as strong as some other jasmines like Sambac for example. However flowers do have a sweet scent especially in the early morning hours, as long as the plant is well-established, grows in a warm and humid environment. Keep in mind that flowers on young small plants that do not have a developed root system, may not be as fragrant as on mature vigorous specimens. Also, this jasmine needs a full sun location and regular fertilizer for profuse flowering.
We recommend the following fertilizers to boost flowering energy:
- Pink N Good Daily Plant Food - Flower Booster
- Plumeria Top Dress - Smart-Release Booster
Use microelements at least once a month to improve plant vigor and quality of flowers

Grafted Guanabana - what is the trick?

Q:Should I buy grafted Guanabana or a seedling? It is a big price difference. I have heard that Annonas fruit within 3 years from seed, why do I need a grafted tree?

A: Annona muricata - Guanabana, or Soursop - is known as the best tasting Annona fruit. Many fruit lovers and gardeners want to have this tree in their plant collection, and the first question they always ask is: "How soon will it fruit? I can't wait to enjoy its deliciousness!"
Most Annonas start flowering and fruiting at a young age, 3-4 years from seed. Annona muricata seedling takes longer. You may read more information on how to grow Guanabanas from seed, even in a pot, even indoors - in Tropical Treasures Magazine issue # 7. Although it may take up to 15 years to see the fruit...
Now we have a solution to get this fruit sooner - a grafted tree! It will fruit within a year after planting. The secret of grafting Guanabana was almost lost (it's a tricky one to graft) and grafted plants were nearly impossible to find. Now we have them! Quantities are limited.
Keep in mind that Guanabana is very cold sensitive and won't tolerate even light freeze. However it is still relatively easy to grow even in subtropical areas: the tree is small, and if tree grown in ground, a simple cold protection structure can be built around it using basic wood or pipes (metal or PVC) and covered with plastic for a few weeks of cold weather. Grafted Guanabana is also a perfect choice for container culture (hand-pollinating maybe required).

Photo: This grafted tree was planted less than a year ago, and was covered in winter with cold protection for about 8 weeks. Within a year, it has 4 large fruit on it!

Climate change is wiping out the Baobab, Africa's tree of life...

According to The Guardian News and Media, Africa's "tree of life" may not have much longer left... These highly important species are threatened with extinction, due to climate change and human development. Some species may not survive the next century. While plants have generally adapted to extended droughts, climate change is different, and with the Anthropocene, we are already witnessing the loss of these impressive trees. Africa's largest, oldest inhabitants, that have played silent witness to numerous generations, are already paying a heavy price for the environmental crimes of foreign lands.
Baobab forms an integral part in people's livelihoods. In West Africa, it is also called the "palaver tree" because of its social functions: when there is a problem in the community, meeting under the Baobab tree with the chief or the tribesmen would be synonymous with trying to find a solution to that problem; it reinforces trust and respect among members of the community. Its extinction would not simply be an environmental tragedy...

Every tropical gardener should have a Baobab to help to save this amazing species for the planet!

How to grow the biggest fruit on Earth...

Q: When I visited Thailand I bought this huge fruit at the market and the taste was amazing and unique! Now I see you have this Jackfruit tree for sale. I am excited to grow it but not sure if it will survive our winters. I live in Huston, TX. Also are there any special conditions required for successful fruiting?

A: Jackfruit indeed is one of the most fascinating tropical fruit. In spite of reputation being ultra tropical, the tree is not as cold sensitive as everyone believes. Mature trees can withstand light frost for a few hours without significant damage. The only thing, after cold snaps it may be not as profuse producer as in frost-free climates. Keeping Jackfruit in a pot is also an option in colder areas. The tree is quite unique not only about fruit but also about growth habit. The fruit is so large and heavy that the tree has a smart feature to produce only at the base of the trunk. This makes it possible to keep Jackfruit tree at very short height - 6-7 ft tall. We have many varieties of Jackfruit, and all of them can be grown in containers considering regular topping/pruning.

5 secrets of Jackfruit successful production:
1) Frost free temperatures (occasional cold spells are not critical if SUNSHINE-T cold protection booster is used)
2) Soil rich of organic matter (compost, manure, peat moss)
3) Moist soil and regular watering
4) Constant pruning and keeping under 7-10 ft
5) Regular application of fertilizer, microelements and SUNSHINE-Honey for better quality fruit.
