Mango ID and ripeness

Q: As the World's Leading Authority on Tropical Plants, I hope you can help us out. We obtained a mango tree from a City giveaway, and planted it a few years ago. This is the 1st year it has produced fruit. They are almost all green color, & range from 6-7 inches in length. Attached are a few photos of the tree & its fruit. Please help to identify the type, and how to determine when they would be ready to pick. Or should we just wait until they fall off of the tree?

A: If the tree is grafted, it normally starts flowering within a year after planting. If the tree is over 6 years old and just now started fruiting - chances are, this is a seedling (possible at giveaways) without specific variety. However the fruit looks pretty good size and shape, hopefully it tastes great. You will find out soon!
Based on the pictures, there maybe a few possible choices, including varieties (or their seedlings) Keitt, Rosigold, it can be even Lancetilla if fruit grows bigger than 7" long. The next step would be, wait until the fruit get some color, then it will be easier to narrow down the variety. Also see if there is a lot of fiber or no fiber.
You may wait until at least one fruit ripens on the tree and let it fall naturally - that will be the color (can be all green, but in your case it looks like it's turning yellow blush). After that, you may pick full size fruit before they fall and let them ripen on a kitchen table. Usually once the fruit starts showing color, it is close to ripening. For all-green varieties, just wait till fruit grows to maximum full size. You may also check if the fruit gets softer to touch, then it's ready.

The best Loquat varieties with big, sweet fruit

Q: I'm interested in loquat and read through the varieties you offer but wanted your recommendation. I'm looking for a variety that is big, sweet (not tart) with 1 seed. Of the varieties you offer... Which variety would you recommend?

A: From our experience, the most popular Loquat variety is Christmas. It is an early ripening type hence the name Christmas. Fruits are very large for a loquat, they are bright yellow with a tangy apricot flavor.
Another good variety we recommend is Yehuda - it has a large fruit and very small seed Also, variety Oliver for many years has been considered the best loquat for South Florida. The fruiting season is March to May. It has medium to large fruit. The fruit is very sweet with only one-two seeds.
Loquats are very cold hardy tropical fruit trees, easy to grow, drought tolerant, fast growing. Fruit is great for eating fresh or making jam.

How to feed Poinciana tree

(and other tropical flowering trees)

Q: We purchased a Royal Poinciana tree from TopTropicals not too long ago and we gradually gave it more sun until finally we were able to plant it in direct sunlight where it's been for a week or so. Rain has been sporadic lately so I'm giving it a little bit of water every day. It seems to be doing fine. I do have a question about whether the leaves are as green as they should be? I read online that I should fertilize it with gardenia / ixoria fertilizer in March, June, and October. I looked on homedepot.com but didn't really find anything that goes by that name. Would fertilizer help? Can you suggest a fertilizer?

A: Your Poinciana tree looks pretty healthy and happy, congratulations with a great job!
Traditional (old-school) fertilizer recommendations usually suggest feeding a plant 2-3 times a year with a slow-release fertilizer. And although a plant will benefit from any fertilizer application (extra food is always good), however, for the best results, faster growth, sooner and more profuse blooming, your should use complete plant nutrition products - liquid fertilizers (see why liquid fertilizers are better than dry).
Here is an example. Some people eat a big heavy meal once a day which we all know, is not very healthy. Other people eat balanced food more frequently but in smaller portions - this is always the best way to go.
From this point, plants prefer SNACKING - frequent feeding, but with less concentrated, mild and balanced nutrients.
For your beautiful Poinciana tree (and other flowering plants), we suggest the following nutrition program:

1) SUNSHINE Megaflor - Bloom Nutrition Booster - you may use this fertilizer as frequent as with every watering, it won't burn the roots, and will provide a complete nutrition for all plant needs throughout the year. You can continue fertilizing with Megaflor even during winter time. Sunshine Megaflor will help you to keep the plant healthy, vigorous, and resistant to stress and diseases. It turns leaves green and makes the plant strong so it will start flowering sooner for you.

2) Tropical Allure - Smart-Release Booster. Apply it once a month during hot season only (in Florida - from March to November).

Plant of the Month: Golden Dewdrop - Duranta erecta

Stevie's Pick: what's in bloom?

Our exotic plant grower Steven Gowdy is featuring the most interesting plants he discovers and recommends today while working in TopTropicals greenhouses.

Duranta - Golden Dewdrop - is simply stunning with cascading flowers in abundance. Either it has lavender, blue, or solid white flowers, it is a sight to behold. The popular name Golden Dewdrop is inspired by the clusters of bright orange-yellow berries that follow the flowers, in such quantities that they often cause the slender branches to droop gracefully.
Duranta erecta blooms off and on all year and can be pruned to size as a bush or a standard tree. If let go, it can grow up to 20 feet tall and wide.
Durantas are excellent butterfly and hummingbird attractors. They will complement your tropical garden or a stand alone in your Southern landscape. Great for providing a color contrast in the landscape, they are especially well-suited as a bright-colored background or screening.
White Golden Dewdrop has pure white flowers that appear in loose clusters, and both berries and blossoms are often seen on a plant. This evergreen fast growing shrub spreads and arches to 10 feet tall and wide and is great for live hedges and covering fences and corners.
Variegated variety, also called Variegated Sky Flower, is grown for its summer flowers, and very showy leaves that are dark green with bright white variegation and creamy-yellow margins around the one inch long serrated leaves.. In the summer, cascading clusters of blue tubular flowers appear followed by wonderfully contrasting orange-yellow berries.
In mild climates, Durantas can be in flower nearly year round with flowers and fruit appearing at the same time. It does best in full sun with frequent deep watering and is pretty hardy, to about 20-25F. It is a good choice for espaliers, as a small tree or large bush; all forms benefit from frequent selective pruning. Prune back in late-winter to encourage a more compact shape and strong flush of fresh spring foliage. Requires moderate watering in a well-drained soil.

How to feed a Mango tree...
and to grow a Dwarf Mango

How to fertilize a Mango tree

Q: My mango trees that I bought and planted last august now have fruit. I bought 2 types of fertilizer from you and never used it. Should I use your fertilizer now?

A: It is a perfect time now to fertilize your plants as they start active growth. For mango trees, we recommend liquid fertilizer Sunshine Booster - Mango Tango. It is formulated for Mango trees, especially for container grown. It improves quantity and quality of flowers and ability to set fruit, reduces bud-flower-fruit drop. Can be used as often as with every watering. For best results, use in combination with Sunshine Honey and Sunshine Superfood plant supplements. Its scientifically-balanced stable formula is organic Amino-acid based and has NO EDTA chelators to eliminate nutrients lockup; it does not affect crop taste.
Additionally, you may use slow-release granulated fertilizer Mango-Food once a month during hot season only. Dosage: 1 teaspoon per each gal of soil. Water-soluble fertilizers can be also used, however, those are usually EDTA-chelated which is not as efficient as Amono-acid based Sunshine Boosters and may create nutrients build up, especially if overdosed in containers.
For in-ground mango trees, you may use all the above, and slow-release granulated fertilizer can be applied in larger quantities: spread a handful around the drip line.

Remember that only liquid Sunshine Boosters can be applied year around. With other fertilizers, you need to be careful not to overdose, and apply only during hot weather (when night temperatures are steadily above 65F).

How to grow a Dwarf Mango tree

Q: I received the Ice cream mango tree in great condition (thank you for the ingenious packing job) on Wednesday and have planted it in a pot slightly bigger than the root ball. I plan to grow the tree on my front porch, so how big a container should I ultimately use when the tree outgrows this pot? How big a container does it need to fruit? I hope to keep it around 6-7 feet high, if possible. I live in Hawaii.

A: Ice Cream mango is a perfect variety for container culture, and it should be happy in Hawaii. You did everything right. Keep it in this small pot for now and wait until it starts vigorous growth in Summer. Once it starts growing (and you will notice roots growing too, sometimes they try to grow through the holes in the bottom of the pot), then it's time to step up into a bigger container (7-10 gal). Eventually you may use container size as large as 15 gal. Ice cream mango is slow growing and compact, and you will be able to maintain it under 7 ft with very minimal pruning if any.
