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!

Growing fruit trees in containers
Will it fruit in a pot? YES!
Many tropical fruit trees can be grown in a pot. We get many calls from customers in cooler climates asking if our tropical trees can grow and fruit in a pot. The answer is yes!
Several plants fruit well in pots. Blackberries and raspberries, barbados cherries, blueberries and many more start fruiting even in their 1 gallon containers. We are especially excited about our new Pixie grapes, which are heavily laden with grapes even at only a foot long!
While some plants are small and will fruit easily in a container, others are large trees. For the tree type fruits, we recommend growing only non-seedling plants for pot culture. We have cuttings, air layers and grafted plants that are great options. These have the ability to fruit right away, as they are the same age as the parent tree. Some horticulturists recommend removing the first year fruit to allow the plant to focus on growth and establishing. If the plant is being kept in a pot, this is not necessary.
We also have several dwarf varieties of fruit trees that will thrive in a pot. For avocados, we carry the Wurtz variety which is a dwarf tree... read more...

Q: I live in California and about a month ago ordered several plants from you, including fruit trees (Carambola, Mango, Avocado) and flowering trees (Xanthostemon, Adeniums, Champaca, Ylang Ylang). They were all doing well until I tried to move them into full sun, when they got leaf burn immediately. Ylang Ylang was doing great in a shade, but I repotted it from 1 gal into 3 gal and it is drooping leaves now. It has been very hot (over 100F) and dry (humidity is less than 25%). Any suggestions?
A: Hot summer can be pretty challenging time for establishing new plants. These are some guidelines to make your summer gardening more successful and rewarding.
1. You can order plants at any time, but keep your eye on your local weather forecast and try to chose cooler periods to schedule your plant shipments. Here at TopTropcals we monitor weather at destinations, and we can also delay shipment per your request until more favorable conditions.
2. During hot Summer months, many plants are still OK to ship, and to be planted, many species are heat tolerant. It's usually safe to ship most succulents, including Desert roses and Euphorbias. Some fruit trees are pretty easy too, like Loquats, Mango, Eugenias. Many flowering trees can take heat: Acacias, Clusias, Jatropha, Sausage Tree, Plumerias and many others. Check our full list of plants suitable for hot and dry conditions. Most jasmines, including Jasmine Sambac and Trachelospermum make also a safe choice for hot weather planting.
3. Use shade cloth or simply white sheets to protect young plants and new plantings from hot sun.
4. When establishing mail ordered plants during hot weather, keep them in shade for longer period of time than average recommended 1-2 weeks. Give them a chance to establish really well. In areas with low air humidity, try to create a simple mist system. It can be purchased in your local Home Depot for only $20 and set up takes only 10 minutes! It makes a big difference and can help you save many plants from hot weather stress.
5. Although it may seem that during hot weather plants need more water due to high evaporation, be careful with watering, and check soil with your finger before watering - don't water if it is still wet. Combination of "hot and wet" can be as harmful for the root system as "cold and wet" during winter. Protect root systems from overheating: covering black pots with white cloth will work. Remember when temperature is above 90F, most of plants slow down their metabolism, which means roots slow down or even stop pumping water and become more vulnerable to overwatering. For the same reason, do not hurry to step up into bigger container if roots haven't filled yet the existing pot.

Taking care of Soursop after shipping
Q: Since I have never grown a soursop tree before I need some pro help. My tree was delivered absolutely beautiful, leaves were a pretty green. I potted it and gave it a good drink of water and put it in a shaded area outside. Then the weather here became cool so I brought it in for a few days until the weather warmed, and it lost all the leaves. Is it in shock and will come around eventually? Will I be able to grow this tree indoors during winter?
A: Soursop - Annona muricata trees are very sensitive to temperature drops. This always causes leaf loss.
You seem to be doing everything right. Do not water until soil gets slightly dry; keep it in bright shade. The weather should be good now with high temperatures and humidity rising. No fertilizer until the plant shows active new growth. Be patient with your plant, it should recover soon.
Soursop is an ultra-tropical tree and doesn't take any freeze. If you live in cooler climate, keep the plant in a pot (the good news is, Annonas in general have compact nature and are perfect for container culture). Bring the tree indoors during cold period, providing bright light.
We have very interesting article about growing and fruiting Soursop in apartment. Check out 4534 Tropical Treasures Magazine # 7.

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.

Calories Burned Gardening
Fun workout? We never have enough time to go to the gym or do an exercise so it's good to know that just doing something that you love can give you a workout. We all know that when we are out in the garden it gives us a bit of exercise but we do not realize how much exactly. Working out in the yard is a healthy hobby for many reasons, the high number of calories burned gardening being one of them. When you do this kind of physical labor, you carry out a wide variety of movements that most definitely burn calories, and may even tone. The best part about it in terms of physical activity is that if you enjoy yard work at all, you aren't watching the clock or counting down the minutes until you are done (the way that many people do while they are on a treadmill). You can easily spend a whole afternoon or an entire day working without feeling as though you are putting yourself through a mentally grueling workout. Finding physical activities that you enjoy are key to maintaining a healthy weight throughout your lifetime, and this hobby is a perfect example of that scenario for many people.
Research says that three hours of gardening can have the same effect as an intense 1-hour gym session. The study was carried out with a group of 100 gardeners who were asked to monitor the amount of time spent doing a series of common gardening tasks over a four week period. Gardening tasks that were monitored included weeding, digging, mowing the lawn, hedge trimming, trimming shrubs and trees, raking, planting shrubs, and moving garden waste using a wheel barrow. Here are some facts and numbers:
- Just doing half an hour weeding can burn up to 150 calories and tasks that handle heavy electrical equipment such as hedge trimming will give you a good workout burning 400 calories per hour.
- Spending a day or five hours each week in the garden will burn up to around 700 calories
- Over a gardening season that works out at 18,772 calories per year, equivalent to running seven marathons
- The gardening hobby could help burn a million calories over a lifetime.
Calories burned with only 1 hour of:
340 cal - Chopping wood, splitting logs, gardening with heavy power tools, tilling a garden, chain saw. Mowing lawn, walk, hand mower. Shoveling by hand.
272 cal - Carrying, loading or stacking wood, loading/unloading or carrying lumber, digging, spading, filling garden, composting, laying crushed rock or sod. Clearing land, hauling branches, wheelbarrow chores.
238 cal - Operating blower, walking. Planting seedlings, shrubs, trees, trimming shrubs or trees, manual cutter. Weeding, cultivating garden.
224 cal - Raking lawn, sacking grass and leaves
136 cal - Picking fruit off trees, picking up yard, picking flowers or vegetables. Walking, gathering gardening tools.
102 cal - Walking, applying fertilizer or seeding a lawn
34 cal - Watering lawn or garden, standing or walking

Hardy avocados
Q: I intend to gift three avocados, at least one type A and one type B, to a friend who lives in an area where the temperature never goes below 25F. The idea is to give them a ripening season as long as possible. Which combinations do you suggest, and which are the A and B?
A: When talking about "A" type and "B" type in Avocados, it is referring to the flowers. An avocado will produce both male and female flowers on the same plant. "A" type means that the flowers are female in the morning and male at afternoon. "B" type means that the flowers are male in the morning and female in the afternoon. If you plant to start a commercial growth, then it's important to create a proper mix of both types. However, in hot and humid climate a single tree produces flowers of both types, so it is not necessary to have both A- and B- types planted together in backyard. Even a single tree produces enough fruits for home gardener.
It is also important to know that while there are more cold hardy avocados, it refers to a full grown established tree. They will still need protection from the cold until they are bigger and more established. One can not expect a small tree, which was planted in June, to survive the first winter. It'll take few years until the tree is "harden" enough.
Wurtz Avocado: Fruits from May to Sept.
Dwarf hybrid. It is very compact and slow growing, reaching only about 8-12 feet at maturity. Distinctive weeping growth habit. Suited for planters, containers, patios, greenhouse use. Great for dooryard or container growing. The tree can handle temperatures to 25(F) degrees. Production is good and it is a consistent bearer.
Day Avocado: Fruits July to Sept.
Day avocado is green, smooth skin and is shaped like a club. The fruit is of very good quality and has a nice buttery consistency. The slender tree is relatively cold tolerant and produces July through September.
Fuerte Avocado: Fruits Nov to June.
Relatively cold hardy variety. Green fruit, elongated,flavor excellent, buttery. Vigorous compact tree with decidedly alternate year bearing habit. Ripens November to June.
These three will provide you with fruit ripening during the whole warm season.

Erblichia or Flor de Fuego - Apricot fragrance and sunny color
Q: I saw this wonderful flower Flor de Fuego on your website and I would like to buy this plant. I am wondering how big this tree will grow and how long will it take until I can smell the lovely flowers? I have a big garden and not much space left, but I still have a few spots available for smaller trees. Also any special care info will be appreciated.
A: Flor de Fuego is a small tree and will fit in any small yard situation. It is very rare in cultivation. This is the newest, most exciting tree to be introduced in the last decade. It said to be one of the most beautiful flowering trees in Central America. It has long narrow leaves and large flowers 6-8" across that smell like apricots. It blooms from late fall through early winter and sometimes through spring. Normally it starts blooming in 2-3 years after planted in the ground. Surprisingly for such a delicate plant, it tolerates poor soils. Once established, it doesn't require any special care other than regular watering and fertilizing during hot months. It does take some effort sometimes to make the tree happy in its new habitat. After planting in the ground, keep your eye on irrigation schedule and do not let soil stay wet, young trees don't like wet feet. In natural habitat, the plant prefers to have a dry period that is beneficial for profuse blooming.
