Grafted Guanabana - what is the trick?

TopTropicals.com

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!

How to get gingers to bloom

TopTropicals.com

Q: I have several gingers in my yard, including Red Torch, Lobster Claw, and Red Bamboo Ginger, they grow beautifully but only produce large dark green leaves and no flowers. Is there anything I can do to make them bloom? Do they need any special fertilizer?

A: Gingers are easy to grow tropical plants with so many benefits, giving us unique spice, and showy flowers (including long-lasting cut flowers!) - where other plants fail, especially in deep shade. They are not fussy about soils and even water once established. To keep your gingers happy, follow these simple steps:

1. Bright light is essential for flowering, but planting gingers in semi-shade or filtered light will keep them stress-free from burning summer rays.
2. Water gingers regularly until they established and start producing new leaves and stems. Once they start clumping, you may reduce watering to a minimum 9once a week or so), or rely on your sprinkler system.
3. Once the plant is established, start using fertilizer to induce flowering and healthy growth.
- We recommend granulated "smart release" fertilizer for all tropical plants. For gingers, the best formula is Tropical Allure. It provides all macro- and microelements essential for the healthy growth of the plant.
- Apply balanced water-soluble plant food for Gingers, Heliconias and Bananas - Broad Leaf Plus - once a month.
- Additionally, you may also add to the menu flower booster Pink N Good Daly Plant Food - this fertilizer is used in very low concentration and can be used with every watering.
4. Remove old dry and yellowing leaves with sharp cutters to avoid pest problems and keep good air circulation around these clumping plants.
5. Keep soil covered with 1" mulch to protect from weeds and maintain the optimal amount of moisture for the rhizomes.

The most desired iconic Chanel flower...

TopTropicals.com

By Onika Amell, tropical flower specialist

Q: I live in Beverly Hills, Los Angeles. I'm looking for something fragrant to grow on my porch. I don't have a lot of space and am interested to find something unusual that won't grow too large. Any suggestions? I've heard about Chanel #5 tree and I wonder I can keep it in a pot?

A: The Ylang-Ylang tree, Cananga odorata, emits a fragrance so soft and beautiful it became an essential ingredient of Coco Chanel's iconic and much-loved perfume Chanel No 5. Trouble is, it will grow into a giant. How do you get this kind of magic onto your lanai or porch? Opt for its smaller relative: Dwarf Ylang Ylang, Cananga fruticosa (pronounced ee-lang ee-lang, meaning: flowers of flowers).

The fragrance is a little less intense than its larger cousin, but still wonderful to have around. Let the fragrance drift slowly through the air into your home at night. The scent is strongest from dusk to dawn and it will need warm and humid conditions for a fuller aroma.
Dwarf Ylang-Ylang is ideal for folks with limited space as it can be grown in a container or as a house plant. It's a very unusual and interesting plant to add to your porch, lanai or garden. It's pretty easy to grow and disease resistant too. It will stay compact and in nice tree-like shape. Dwarf Ylang Ylang starts blooming quite young and will continue to bloom year-round with profuse blooming during the spring and summer months.
The tree prefers a high-humidity environment, evenly moist soil, warm temperatures and will grow best in plant hardiness zones 10-11 but can take short periods of cold.

Dwarf Ylang Ylang is certainly one of the most desired and sought after rare, fragrant plants. Get yours today!

How to propagate plants from cuttings. Top (Tropicals) secrets.

TopTropicals.com

Q: After pruning my jasmine, I have so many branches and I don't have a heart to through them away, can I use them to make more plants? Please tell me what size cuttings and do I need to remove leaves? Should I just stick them in the ground? Will they root? I don't know if you will be willing to share your secrets?

A: We are always happy to know that you grow more plants, and make our World better! These are some useful tips for the propagation of tropical plants using cuttings:

- Cuttings and leaves. Use cuttings 2-5" long. Strip leaves from the bottom. Cut larger leaves in half to reduce evaporation.
- Soak cuttings for 15-30 min in SUNSHINE solution.
- Mix. Use special well-drained mix with lots of soil conditioner: we have a special professional propagation mix for cuttings.
- Mist. Put community pots or trays with cuttings in mist, or if you don't have mist - cover the pot with a clear plastic bag to create a mini-greenhouse.
- Shade. Keep propagation pots in bright shade and never allow direct sun rays.
- Rooting hormone: yes, use it if you have it. Not only it promotes root formation but also prevents from fungus so the cuttings won't rot. We use Dip-N-Grow.
- Rooting and food. Check in 2-3 weeks for roots. Once you see the little roots, begin fertilizing with a special Baby-Plant Food and make sure never exceed recommended doze otherwise you may kill the cuttings.
- Establishing. Once roots start growing, plant in 4" pots in a well-drained potting mix and watch the beauty grow! Gradually move to the full sun only when little plants establish and start new growth.

If you are lucky to make more rare plants than you can use, contact us, we will buy them from you or trade for your dream plants! In fact, one of our customers from many years ago started selling us baby plants that he propagated from our plants, and now has a successful business (Karma Nursery); we buy a lot of plants from him every month!

Fruit tree size and production

TopTropicals.com

Q: I am interested in a Strawberry Tree... does this tree produce fruit while still small or do I have to wait until it is large before it produces? Should I fertilize it so it produces sooner? I ask because my garden is not large and I prefer to keep my fruit growing trees in a smaller size. Also, how big is the fruit and does it have a seed?

A: Strawberry Tree, Muntingia Calabura, is one of those fascinating fruit trees that starts flowering and fruiting in small size. We have plants growing in 1 gal containers that already have flowers. This tree is nearly year-round producer providing warm conditions. It is a fast grower, although a compact tree when mature, and can be trimmed to desirable size without affecting production.
Muntingia fruit is one of our favorites. It is super sweet and juicy, and the seeds are tiny small, not bigger than the strawberry seeds, so you don't have to spit them out. The fruit size normally about 1/2 inch, but we have a tree in our garden that produces almost cherry-size fruit! See picture above. The secret is, good watering and using fruit booster - SUNSHINE honey micro-element supplement. We also fertilize our fruit trees using Fruit Festival and Mango-Food fertilizers.

Secrets of Happy Bougainvilleas

TopTropicals.com

Q: When I visited Hawaii I saw their everblooming bougainvilles, flowering non-stop! How come our bougainvilles in Florida are not flowering as much? Is there any special secret to make them bloom?

A: Bougainvilleas prefer drier climate and especially drier summers. Florida summers are rainy and humid. The steaming greenhouse conditions are favorable for most tropical plants (except desert plants like most cacti). Bougainvilleas also grow vigorously in Florida heat and frequent rains, but most cultivars prefer dryer conditions for profuse flowering. These are a few tips that can help you grow happy Bougainvilleas and enjoy their showy flowers even in humid climates:

- In Florida, Bougainvilleas bloom mostly in Winter. If you are a snowbird, this plant is definitely for you!
- Choose sunny, dry, and elevated location for Bougainvilleas, never a low spot and never a shade spot. Give it as many hours of sun as possible.
- Use only well-draining soil. Usually, sandy soils work well when mixed with some compost. If your soil is too heavy, add soil conditioners like perlite, bark, sand.
- Take advantage of cultivars that are well adapted to humid climates: Dwarf Everblooming Pixie, Thornless B. arborea.
- Remember Bougainvilleas are the easiest and the most rewarding potted plants.
- Use bloom boosters along with well-balanced slow release plant food. We recommend these: Pink-N-Good flower booster and smart-release granulated Tropical Allure.
- Do not overwater and keep the plant on a dry side.

Mulberries - biggest, sweetest, and compact...

TopTropicals.com

Q: What is the difference between Pakistani and Australian Mulberry plants? Would one be better suited for South Florida backyard? Can one be maintained/pruned to be a tall shrub vs a large tree? Which one has the sweetest fruit? Thank you for the previous plants we've purchased from you. They're all doing great.!

A: These two varieties are very similar indeed. Both fruit are very large. Var. Pakistani fruit is a little longer than var. Australia and the tree is a more vigorous grower, but they both are very sweet, even before the fruit fully ripen. Both trees are a good choice and start fruiting at a young age.
We've had Australia in the ground in our garden for 4 years by now and for some reason, it has been very slow growing which is normally not the case with Mulberries. Maybe it is not fully happy with FL humid conditions.
There are two Mulberry varieties that can be maintained as bushes: Issai and Dwarf Everbearing. However, even vigorous Mulberry trees respond well to pruning and can be kept compact for easy harvesting. Just make sure to prune before the flowering season starts; here in S Florida Mulberries start flowering in March, and fruit start ripening during April-May.

Dwarf Red Ginger - more than just a pretty face

TopTropicals.com

Q: I've just recently moved to Florida from North Carolina. I don't know much about tropical plants. Can you perhaps suggest an easy and pretty flowering plant for a beginner which I can plant around my garden pond for a tropical feeling?

A: For adding that tropical look to your garden, few plants beat beautiful ginger! Alpinia purpurata, the Dwarf Red Cone Ginger with its bright red floral spikes and lush, lance-shaped foliage is no exception. This striking perennial will add a tropical effect to your garden that will definitely take your breath away.
The Dwarf Red Cone grows between 3 and 4 feet tall and blooms 8-9 months of the year! The blooms will hold on the plant for up to 3 weeks! It makes a very attractive and distinctive backdrop for other plants.
Red Cone Ginger likes partial shade and moist, humid conditions, but will tolerate full sun. It is fast growing, easy to grow and resistant to disease, heat, and insects. The plant is a wonderful accent in a garden and works well as a focal point specimen, show-stopping when planted around garden ponds or near entryways. This ginger also works very well in containers and planters. Either in mass plantings or smaller groups, all gingers add tropical flair which never disappoints.
In addition, the beautiful flower spikes make for great, long-lasting cut flowers and is an interesting addition to bouquets.
An added bonus? Dwarf Red Ginger is super easy to propagate. If stems are cut at the base and placed in water, they will generally root within a few weeks. Eventually, you can make a whole flowering hedge just from one plant!

Who does not like a plant that is non-fussy and not only beautiful but easy to grow? Dwarf Red Ginger is more than just a pretty face!

To keep this plant happy and blooming, give it some food: Broad Leaf Plus - Ginger-Heliconia-Banana Booster.

Myco Mix - magic mix with Mycorrhiza

A word from the owner...
