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!

How to get gingers to bloom

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.

7000 stones for 7000 trees...

In 1982, a German artist Joseph Beuys proposed a plan to plant 7000 oaks throughout the city of Kassel, each paired with a basalt stone. The 7000 stones were piled up on the lawn in front of the Museum Fridericianum with the idea that the pile would shrink every time a tree was planted. The project, seen locally as a gesture towards green urban renewal, took five years to complete and has spread to other cities around the world!

We can plant a tree without moving a stone... Just plant and enjoy the beauty!

The Mother of All Bamboo - Bambusoid Grass

By Mark Hooten, the Garden Doc

The missing genetic link is found! The tiny little "bambusoid grass" is actually the original ancient ancestor of Bamboo and all members of the Bambusoideae, the giant woody grasses! This plant is the evolutionary mother of ALL modern bamboo's that that has just never really been made available to the general public...
...So I decided to begin propagating my own Lithachne humilis colony. After a few months of hovering over delicate seedlings, I have a few to offer! But there is a story behind it... Continue reading...

The most desired iconic Chanel flower...

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!

Breathtaking Queen's Wreath

By Onika Amell, tropical flower specialist

Q: I've just moved from Virginia to Sarasota, Florida. I'm looking for a vine similar to Wisteria to grow in my new garden. I've so enjoyed my Wisteria vine and I'm hoping to find something equally spectacular for my FL garden. Truth is, I'm getting older and won't be able to keep up with the hard-core maintenance Wisteria needs to keep it in under control. Is there a similar vine you can recommend that is just as showstopping as Wisteria?

A: The vine that immediately comes to mind is Petrea Volubilis or Queens wreath. It looks similar to Wisteria, and though a fast and strong climber, it's not invasive or destructive at all. An occasional pruning is all it will need to maintain it. Much like Wisteria it gives a glorious show of flowers when spring arrives. Masses of long, mauve flowers will continue to appear on and off in summer with another burst of flowers in the fall. Flowers are up to a foot in length!
Hummingbirds, bees, and butterflies will all be impressed with you for growing this charmer.
Snip off the gorgeous flowers, put them in shallow bowls of water around your home and be the envy of all your friends and house guests!
This vine prefers the warmth of Zone 10 to thrive, but it will survive in areas of Zone 9B when it borders zone 10A, especially if it's placed in a protected area. It grows best in full sun but will tolerate part shade. It's great for coastal gardens and once established, it has good drought tolerance, medium salt tolerance, and good wind tolerance. It has no major pest problems, which is always a bonus.
Grow and shape it as you like: a large bush, a small tree or a breathtaking espalier. Some people plant Petrea vine by a tree to create that much sought-after ethereal wisteria effect. This is no doubt a very charming vine and a must-have for those who are in love with Wisteria but scared of its vigorous growth and ongoing maintenance.
For Wisteria lovers we also recommend its spectacular tropical relative Millettia reticulata - Evergreen Wisteria.

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

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!

Impossibly exotic Chalice Vine

By Onika Amell, our flower specialist

Q: I live on Sanibel Island, Florida and I'm looking for an exotic vine to cover the side of my house. A friend suggested Chalice vine. What can you tell me about it and will it tolerate the salty soil and salt spray of the island?

A: Chalice vine, or Cup of Gold - Solandra maxima - is a large, woody, scrambling tropical vine with huge, cup-shaped flowers. Variety Variegata has also amazing cream and green variegated foliage. The flowers are fragrant, especially in the evenings, with a lovely coconut-like aroma. This unusual vine will give you intermittent waves of large, wide flaring golden trumpets.
Even when not in flower, it is beautiful as new growth is bright and purple-bronze in color. It has a large and loose spreading habit. As this vine ages, flowers will appear along the entire length of branches off the main vine. So, just think about it - up to 100 feet vine and you will have about 500 flowers at the same time! They are very fast growing and usually bloom from February until May. Plant them... Sit back and wait... Four months of heaven!
They are great for seaside gardens as they are very tolerant of salt spray and salty soils. Will, in fact, thrive in most any well-drained soil.
Give it a large, sturdy pergola or trellis, or train it to grow up the side of a house where it will spill down over windows and doorways to take your breath away... Chalice vine is impossibly exotic!
