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
3. Bay Leaf (Laurus nobilis)
4. Mint Tree (Satureja vimenea)
5. Vanilla orchid (Vanilla planifolia)

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.

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.

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.

Growing from seeds

Q: What is the best time to start tropical plants from seeds? Should I wait till summer?

A: Traditionally, people prefer sowing seeds in spring, especially temperate species for vegetable garden: tomatoes, peppers, cucumbers...

When dealing with tropical plants, you may want to start your babies indoors, providing additional heating when needed. If you keep your living space around 75F (ideal for many species), this is a perfect temperature to get your seeds started. Tropical plants are not like annual tomatoes that try to grow through the season as fast as possible. They may take time. So the sooner you start, the more chances to get small seedlings just in time when spring air outside is warm enough - at least in 70's F.

A great advantage of starting tropical seeds indoors is controlled temperature and moisture. In the plant world, environment extremes are not good for germination process. Mild conditions of your home or a greenhouse create better chances for successful growth. Seeds won't get overheated in hot summer sun, and won't get rotten because of a sudden heavy rain. Just keep in mind that some species require light for good germination. Using an old fish tank or covering with plastic wrap will help to keep constant humidity.

Growing tropicals from seeds.

From Kristi the Wizard of Rose: I grow many plants from seeds, both for my personal collection, and for TopTropicals. I receive many questions from customers who want to grow tropical plants from seeds. Some of them live in colder climates and try to extend growing season of their tropical collections by starting new varieties early in the year from seeds. These are a few tips that may be helpful.

Q: What do I need to do to speed up germination process?

A: Many factors affect germination. Considering you get fresh seeds (for example from TopTropicals) and Mother Nature gives them a good kick start, there are a few things that may speed up germination:
1) Scarification. Large seeds with a hard outer shell can be slightly sanded down just enough for moisture to get inside to wake up the seed during the pre-soaking. Be careful not to damage the seed. See example of Lotus seed scarification.
2) Pre-soaking. We recommend pre-soaking most of the seeds for only a few hours (3-8 depending on species. Some seeds are very sensitive to moisture and may start rotting if stay wet without air circulation. Small seeds, especially tiny ones like dust, should not be soaked.
3) SUNSHINE-S treatment. Adding a few drops of SUNSHINE-S booster when pre-soaking seeds increases their germination rate 3-5 times.
4) Temperature. Warm temperatures help germination. If grown indoors, put seeds containers or trays in the warmest spot of your house; you may use heat pads. Outdoors, putting them in full sun helps a lot, just don't let soil to dry out.

Use only special porous seed germination mix to provide air circulation and prevent seeds from rotting.

Q: Should I keep seeds in refrigerator before planting?

A: Do not refrigerate tropical seeds. Stratification (treatment with cold) works only for temperate species, and some subtropical (like non-tropical Magnolias)

Q: How do you grow eucalyptus from seeds? I tried a few times with no success.

A: The secret of germinating tiny seeds like eucalyptus is - to sow them on top of the moist soil surface (soil must be very fine and soft), without covering. Keep container covered with clear plastic, in bright light. Use spray bottle to keep surface moist but not soggy. I have a customer who germinates eucalyptus seeds using an old fish tank, covered with a glass. Perfect environment - bright light and moist all the time.
