Colors of Cannas

By Onika Amell, tropical flower specialist

Q: I'm a beginner gardener and looking for something easy to grow that will add a lot of color to my garden fast.

A: Try growing Canna lilies. They are a favorite of many gardeners as they are so easy to grow and always provide a reliable, beautiful show of flowers. In fact, Cannas are one of those plants that are spectacular even if they never bloomed. The leaves are tropical-looking, banana-like and huge! They range in a wide variety of shades and colors, always accentuating the large showy flowers on top.
One of our favorite cannas right now is Canna Cleopatra - very striking and most unique. Large yellow flowers speckled with red spots, or red flowers and even flowers with a little bit of both. Foliage is exotic and very beautiful, often dark green, dark chocolate or a combination of both. This is a canna that will definitely illuminate your garden!

Caring for Cannas

Cannas like a lot of water, full sun and high heat. They are also heavy feeders and prefer soils that are well drained, organically rich and moist. The leaves will quickly tell you when the plant is hungry. Feed your cannas weekly with a water-soluble 20-20-20 fertilizer Broad Leaf Plus, and they will quickly respond with beautiful, lush growth. Deadhead often to encourage continued flowering. Cannas are winter hardy in US hardiness zones 7 and warmer. If you live in colder areas, the rhizomes need to be lifted in the fall, and stored indoors in a dark, warm spot until spring arrives. Be sure to divide clumps every three or four years. Give them lots of room as they grow into large plants, forming spreading colonies up to 7 feet high and 4 feet wide. Show them off in mass plantings, in large containers or in mixed flower borders. Lure in hummingbirds with these beauties!

Perfecting a Mango Tree

Q: I recently purchased a Mangifera indica - Coconut Cream Mango from you and would like to know if it is possible to keep this in a large pot rather than putting it in the ground. If so, I have a few questions:
1. How large would you expect this variety to get?
2. What are the ideal growing conditions? Full sun, partial sun, etc...?
3. What is the ideal soil?
4. Any specific watering directions for ideal growth?

A: Coconut Cream mango tree has a moderate growth. We've planted one in our garden 4 years ago and it is still under 10 ft tall. This variety should be well suitable for container culture.
1. Keep the branches trimmed after fruiting is over. Mango trees can be grown in 15 to 25 gal containers and can be trimmed under 7-8 ft high.
2. All mango trees need full sun, the more sun the better.
3. Mango needs very well draining soil, ideally with lots of bark and perlite. We recommend our professional soilless mix or a similar formula.
4. Mango trees hate wet feet, and prefer to stay on a dry side: make sure soil in a pot doesn't stay wet; allow it to dry a little between the waterings.
Remember to apply Mango Food fertilizer during warm season for vigorous growth and heavy crop!

Persimmons - seedlings or grafted?

Q: Do all persimmons take roughly 6 years to fruit if grown from seed?

A: Persimmons, like most of the cultivated fruit trees, are recommended to be grafted to ensure a certain variety, although they may also come true to seed. And unfortunately, you are right - it will take a few years (depending on growing conditions) until the seedling will start fruiting. So your best bet to get a quality fruit right away is to obtain a grafted plant. You may check out persimmons (tropical and subtropical) that we carry in stock. If you are interested in any of the varieties that are currently sold out, just add your email to wishlist by clicking on link Notify me when available and you will be notified as soon as we have it back in stock.

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.
