Cold hardy tropical fruit trees for Luisiana
Q: I've just moved to Louisiana and have been wondering whether it would make sense to plant some tropical fruit trees in our garden. Average lows in New Orleans are 41 deg F in January and February, although we did hit 25 once with the Arctic vortex. I'm interested in litchi, longan, rambutans, and persimmons. Do you have varieties that can tolerate Louisiana's temperature range? I'd love mangosteen but I don't suppose they will survive. Do you have any suggestions on tropical fruit trees that I could try?
A:
Average temperatures are for statistics only; it is actual
temperatures that may hurt your cold sensitive plant. This
is what you should keep in mind when starting your
tropical fruit collection:
1) Ultra-tropical plants like Rambutan can not survive
winters below 45-50F. However, they can be successfully
grown in containers in a greenhouse or moved indoors into
a sun room during cold periods.
2) Tropical plants like Litchi and Longan may take some light
frost once established. Still, for areas with freeze our
advice is - keep them in pots and move inside in case of
cold.
3) There is a number of subtropical fruit trees that are
hardy enough to take some freeze. Persimmon, Feijoa, Fig, Cattley Guava, Jujube, Kiwi, some Eugenias and others. Please
refer to our Tropical Fruit Sensitivity Chart.
4) Remember that plant's ability to survive winter depends
on several factors, not only temperature itself. Important
factors are: wind protection (chill wind kills rather than
low temperature itself), exposure, how close the tree is
planted to the house, plant maturity and its overall
strength and health. If a plant had received good
nutrients during summer, has well established root system,
planted in enclosed area protected from winds and has
plenty of bright sunlight - it has better chances to
survive than a weak plant in warmer conditions.
5) Use SUNSHINE plant boosters for
improving cold tolerance of your tropical plant. It only
takes a few drops, and only costs $5!

6 easiest fruit trees and 5 spices to grow in containers indoors
Q: This is why I want to move so that I can grow absolutely anything I want from your catalogue. Prefered Puerto Rico. Right now I live in New York and there is absolutely nothing I can grow there.
A: Of course living in Puerto Rico brings more opportunities to grow tropical species. However, you can create your unique tropical paradise even living in New York. We have many customers from up North who successfully grow tropical species (and get them to flower and fruit) in greenhouses, and even indoors.
Here are a few suggestions of tropical fruit trees that adapt well for container/indoor culture - for both beginners and advanced gardeners.
Top 6 fruit trees great for indoors / container culture / beginners
1. Mango (Mangifera indica). Select from one of smaller mango varieties
2. Sugar Apple (Annona squamosa)
3. Guanabana, Soursop (Annona muricata)
4. Miracle Fruit (Synsepalum dulcificum)
5. June Plum (Spondias cytherea)
6. Guava (Psidium guajava)
5 top spice plants (the spice will be with you right away, you don't have to wait for it to grow)
1. Allspice (Pimenta dioica)
2. Cinnamomon or Campor tree

Cold protection - winter action for your plant collection
A note from our customer: Last winter was very cold here in Arizona, lower 30's. I used white synthetic sheets (called frost cloth, it is very light and yet effective) to cover my fruit trees, and kept simple light garlands on for the whole night. Sending you couple photos so you can share with others. It worked pretty well for my plants and no cold damage!
With winter approaching, it is time to take some actions to protect your rare plants from cold stress and damage.
If you live in a mild climate, you still need to get ready for the cold nights. When expecting a cold night, individual plants and trees can be wrapped with sheets, or blankets, to protect them from the wind chill. Christmas lights is a good idea for an additional warm up.
For large collections of tropical plants, temporary winter greenhouse doesn't have to be expensive. An easy-assembly mobile carport from a hardware store covered with a plastic or fabric will cost you $100-200. It can fit a hundred plants or more!
If you live in area with a hard freeze, Southern exposure windowsill will work for most of the compact tropicals providing proper care. Larger collections may also move into your garage for a few cold nights, or for longer periods if the garage has a bright light source.
Factors affecting tropical plant winter survival:
1. Duration of cold period. Tropical plants can't stand long periods of cold. A few days of even upper 30's may kill a tropical plant. A few hours of frost may cause leaf drop but the plant will recover.
2. Minimum temperature - of course, the warmer the better. But see 1) - if cold is not for too long, it may be OK.
3. Wind-chill can be more dangerous than low temperatures.
4. Exposure. Southern slopes get warm during daytime and stay warm longer.
5. Protection with a house, fence, larger trees - where a "pocket" of warm air forms and stays - is beneficial.
6. Humidity. A lake or a river nearby (especially ocean) will mild the micro-climate.
7. Individual species hardiness. Don't try to grow Orchid Tree outdoors in New York.
8. Plant maturity and health. A well-established plant with developed root system has more chances to survive cold. If a plant had a good change to develop during warm season (bright light, enough water, fertilizer), it will be more cold hardy. Healthy plant can withstand lower temperature, so proper nutrition is important, including micro-element applications. Large specimens, even ultra-tropical, may survive cooler winter than they normally do in their natural habitat. The Nature provided plants with better hardiness level than it is normally used. To boost plant immune system and improve cold tolerance even more, use SUNSHINE plant boosters. SUNSHINE-T - thermo-protection booster, is specially formulated for winter protection of tropical plants. To improve cold hardiness, spray 1-2 days prior to cold with 5 ml/1 gal solution and continue applications with 2.5 ml/1 gal solution every 10-15 days throughout winter period.
9. Gradual temperature decrease is less dangerous than a sudden drop since it gives a plant a chance to adjust. One sudden freeze in December with prior warm fall may create more damage than a gradual temperature adjustment. If it starts to get cold early in the Fall, plants slow down their metabolism, and the new tender growth won't get hurt later in winter, since the plants are "expecting" the cold.
10. Do not fertilize plants during cool months. Not only because they don't need much food beyond growing season, but also because fertilizer (especially Nitrogen) encourages rapid tender growth that will be damaged by cold and this will stress the whole plant.
Stay warm!

About Cold Protection...
Q: I have a question, if I'm in Okeechobee Florida zone 9b are there any plants that you sell that would have to be protected at all? I have a lot that I've purchased from you and don't want to lose any of them winter.
A: Sometimes it is hard to guarantee if certain plants are hardy enough in certain area. From our experience, tropical plant performance in non-tropical areas depend on many factors; a lot of times plants appear to be hardier than they are believed to be. Other times, an obviously hardy plant doesn't survive winter. So there always will be a chance of risk involved, while nice surprises are not an exception. We have been testing many tropical species throughout many years of our nursery experience. Wind protection in many cases is more important than temperature. Enclosed sections of your garden provide better chances to survive cold snaps. Generally speaking, here is the list of some plants (not complete list, just examples) that in our experience have been surviving light freezes without significant damage.
Q: I live in San Jose,CA. Got Mango Alphonso 2 yrs back and protected it for a year in a pot during winter. Last spring I planted it and during winter I put a freeze cloth to protect it but it died. How can I make sure it wont die if I buy this time plz?
A: Mango trees are tolerant only to light frost, once established.
If it gets below freezing in your area for more than a few hours, and especially if you have numerous nights with frost throughout winter, we recommend to keep mango tree in a pot.
This way it can be moved to protected area during cold night.
The more established the tree, the more chances to survive colder temperatures.
We also use plant booster Sunshine to increase plants cold tolerance
Cold protection is a lengthy subject. You may also use propane heaters during cold nights.
Here is some more information on cold protection.
Also, we recommend to check out our magazine Tropical Treasures (about pushing the limits of tropical gardening) for a detailed article on cold protection.

Some tropical plants like Durian, Breadfruit, Cacao are
rare in plant collections and require true tropical
environment for successful growing and most likely
greenhouse conditions unless you live in mild tropical
climate like Hawaii. These plants are hard to find and are
not cheap. They can be shipped to you in original
containers via Express mail and usually take trip well as
long as there are no delays or overheating (or cold)
during transportation. To enjoy your rare plant collection
gem, please make sure to follow these recommendations:
- Keep your eye on delivery, track the shipment and make
sure package is not left outside in the heat or cold.
- Unpack immediately and put plant in humid, warm
environment with filtered light. Remember, "warm" for
tropical plant means 78-85F.
- If a plant is wilted, put clear plastic bag over leaves
to increase humidity for a few days. Keep the branches
covered with clear plastic, in shade only - to avoid
overheating.
- Keep soil slightly moist and don't let dry out. These
plants like water as well as good drainage.
- Keep plant in original container until recovers from
shipping stress. If necessary, re-pot in 2-3 weeks in
bigger pot with rich organic potting mix, containing a lot
of peat moss, and perlite or bark for good drainage.
- Grow these plants in warm and mild conditions, in
filtered light, high humidity, with no temperature
extremes. Remember to keep these plants at temperatures
above 50F at all times.

Spring is coming, plants need food! Time to fertilize...
Last winter was long and snowy in the most part of our
country. Hold on fellow gardeners up North, it is almost
over!
Here in Florida we have been blessed again with a mild
winter without serious cold snaps. Early Spring that is
already in the air. Look at this picture of flowers in our
front yard now.
If the weather is already warm in your area (low
temperatures above 55), it is time to start fertilizing.
We are sending our love and support to tropical Puerto
Rico suffered from hurricane last year, and will be happy
to help you guys to restore your lost gardens!
CHECK LIST
what
to do to give your garden a good kick start:
1. Slow release granulated food. Apply Slow Release Fertilizer and
continue once a month. 1 tsp per gallon of pot, or a
handful for in-ground plants. This will provide essential
macro elements (NPK) required for a plant growth.
2. Water soluble micro-elements. Besides
macro-elements, plants need many other elements that most
of the time missing in soil. A lack of micro-elements
causes different deficiencies, resulting in weak root
systems, slow growth, deformed leaves, leaves yellowing,
lack or no flowers/fruit. Apply these supplements as a
foliar spray once a month to induce healthy growth and
flower/fruit development. We recommend the following
micro-element products to keep your plants healthy and
vigorous year round:
a) SUNSHINE SuperFood - plant
health booster. This revolutionary new liquid complex
contains ALL microelements needed and can fix all possible
problems occuring to your tropical plants - from roots to
flowers and fruit. We have convenient dropper bottles of 5 ml for small plant
collections, 50 ml for larger gardens, and
100 ml for professional
landscape applications.
b) SUNSHINE-Micro - Microelement
booster - for common iron deficiency (pale leaves)
c) SUNSHINE-Super-Iron -
Microelement booster - for severe iron deficiency
(severe yellowing leaves)
3. SUNSHINE plant boosters -
SUNSHINE-E, -BC (caudex plants and bonsai), -H (house
plants). Apply these natural plant stimulants to
help plants recover from cold, dormancy, increase plant's
metabolism and make a plant more readily absorb both
Macro- and Micro-elements. SUNSHINE boosters also will
help plants grow vigorously, withstand Summer heat and
drought, and produce bigger and better flowers and fruit.
4. Kickstart a sweeter fruit. To get a better and
sweeter crop in Summer and Fall, you need to start first
application now. SUNSHINE Honey - is natural,
Amber-colored, honey-like liquid microelement product for
fruiting and edible plants that will make them sweeter,
tastier and more flavorful! Very effective for tropical
fruits, tubers, vegetables. Great for tropical fruit
trees: Mango, June Plum, Annonas, Tropical Cherries,
Carambola, Citrus; subtropical fruit trees: Peaches,
Apricots, Loquat and berry plants (blackberry, mulberry,
etc.)
5. SUNSHINE-S. Don't
forget to plant seeds! It's a perfect timing
now to start your tropical garden indoors even if it is
still cold outside. Soak them in SUNSHINE-S solution to
increase germination rate.

Q: Can you make my yard bigger and prevent it from freezing?
A:
Yes, we can make your backyard bigger by adding a 3rd dimension - trees as a upper level, shrubs as a second level, vines in between, low growing perennials below them. Add ground covers and potted plants as separate specimens in between in-ground planted trees and shrubs. One more separate dimension is orchids and other epiphytes that happily grow on the trees. This multi-level structure will allow you not only collect so many plants, but also maintain them in a natural environment, similar to how they grow in a wild.
As far as preventing from freezing - it depends. You can use greenhouse, cover plants, create microclimate under large canopies, etc. Some tropical plants are tolerant to light frost, once established. If it gets below freezing in your area for more than a few hours, and especially if you have numerous nights with frost throughout winter, we recommend to keep plants in pots (BTW, this way you save space and can collect even more!). Pots can be moved to protected area during cold nights. The more established the tree, the more chances to survive colder temperatures. You may also use propane heaters during cold nights.
We also use plant booster SUNSHINE boosters to increase plants cold tolerance.

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.

Growing by the sea
Q: Please recommend me some interesting plants that can grow on my waterfront property and can withstand some salt wind. All my neighbors have Sea Grape trees and bougainvilleas, and I want something different and special. I would love to have some colorful or fragrant flowers, or fruit around my paradise home.
Q: Considering your neighbors successfully grow Sea Grape (Coccoloba), and Bougainvilleas, you have a mild, frost free climate. There is a number of spectacular and useful tropical plants that are salt tolerant. Orchid Trees - Bauhinias, Poincettia - Delonix, and Geiger trees - Cordias, are very showy flowering trees. For large size bushes, try Dwarf Poincianas - Caesalpinias, and Scarlet-Coral Erythrinas. Frangipani - Plumeria, come in different colors and bring you perfume fragrance from Hawaii. And of course, Desert Roses - Adeniums, can be grown and showy specimens anywhere in your yard, both in the ground or as potted bonsai.
Most palms, especially popular Coconut Palm, source of tasty fruit and drink, are highly tolerant to salt breeze. If you are looking for something that nobody has, Lipstick palm, or Sealing wax palm - Cyrtostachys lakka, is definitely the most spectacular palm you can find. It is a stunning feather palm that develops a brilliantly red trunk. Palm is originally from Malaysia, but has been introduced to Costa Rica and other tropical areas of the world. Sealing Wax Palm seeds are very slow to germinate, up to a year, and large specimens are very rare and hard to find even in rare tropical plant nurseries. This palm will require a good overhead light, and constant warmth (above temperature 55F). It is definitely worth an effort to grow this beauty.
You may add more tropical accents to your landscape by the sea with many varieties of showy heliconias.

Jungle on Windowsill 101
Q: I got a Jasmine Sambac and a Tahitian gardenia as presents, they are very cute plants with flowers and flower buds. I would like to be able to keep them alive and hopefully happy for a long time, but I don't know much about growing tropical plants, and I am not sure if my thumb is green enough to make everything right. What do they need? How much sun? How much water? What kind of soil? Sorry for all these (maybe silly) questions, but I want to keep them alive, please help! I live in Wisconsin and we had some snow again last week.
A: Growing tropicals is not a hard work, it is a lot of fun! These plants are actually a good starters for a beginner who wants to try growing tropical plants, no matter if you live in a mild frost-free climate, or up North where you can have these beauties as houseplants. Below are a few simple steps for you:
1. Read. Follow planting instructions included with your plants. Check plant names on the tags and learn more about them from our online catalog.
2. Soil. Plant in quality potting mix - it must be porous and well-drained, never use heavy soils (top soil or garden soil are no-no), in a pot exactly the size of the root system. You can step up your plants in the next size container once you notice vigorous new growth. Next size means: 4" pot can go into 6" pot, 6" pot into 10" pot, etc. Too big of a pot may create rotting environment, root system must fill the entire container to use all the moisture from the soil. Container must have good hole(s) for excess water to drain through. Put the pot in a saucer and get rid of excess water every time after watering.
3. Light. Most tropical plants require lots of light in order to produce flowers. If you ever visited Florida, remember the bright sun? - these are ideal light conditions for tropicals. Up North, provide as much light as possible: a bright spot on a windowsill of Southern or Western exposure would work the best. If the sun gets too hot in summer afternoon, you may shade the window a little bit with a sheet of white paper to avoid leaf burn.
4. Water. Keep soil slightly moist but not soggy. The best way is to wait until the top of the soil feels dry to touch - this is time to water again. Jasmines prefer to stay on a dry side; gardenias do not like soil to dry out - keep them slightly moist as long as soil is very porous and well-drained.
The main reason of most problems with potted indoor plants is over watering. With experience, you will feel the right balance of moisture in the soil: the brighter the light, the more water is consumed by a plant; the less light, the less frequent you should water.
5. Trimming. In low light conditions, plants tend to become leggy. Trim branches as they become too long: the more you trim, the busier the plant gets. New growth promotes more profuse blooming in many species.
6. Fertilizing. Fertilize indoor plants with slow-release granulated fertilizer from march to November.
7. Insects. Check for insects at least once a month, especially underneath the leaf. If notice any problems (deformed leaves, residue, holes, or tiny insects) - clean the leaves/stems with a solution of warm water (1 cup), vegetable oil (2 table spoons), and a few drops of a dish soap.
8. Fresh air and air humidity. As soon as air temperature gets above 65F, bring your tropicals outside in the sun and fresh air: porch, balcony, outside in the yard. Air circulation is essential for your plant health. Bright light and high air humidity will promote vigorous growth, and lots of flowers for you to enjoy!
