Healthy Plants. Q&A from Mr Booster: Fertilizing Mango trees in Winter

Q: I'm living in Maryland growing zone 7A and would like some info on when to fertilize my potted mango trees. I ordered your Sunshine Mango Tango 2-2-4. All your mango trees are in pots.

A: You can start using this fertilizer right away, any time of the year, and every time you water your plants.
Sunshine Mango Tango, as well as other Sunshine boosters, is an amino-acid based liquid fertilizer that is scientifically developed for daily plant needs in all necessary nutrients. This means, you may use this fertilizer with every watering, including winter period.
Traditional fertilizers (both granulated and soluble, EDTA-chelated) can only be used during hot months while plants grow actively, and must be limited or not used at all during cooler months, to avoid nutrient lock up in soil (which basically means "building up unused elements"). With Liquid Sunshine Boosters, it is safe to add them every time you water your tree.
During cooler weather and when plant metabolism slows down, a tree will consume less water (as well as food), and you will automatically reduce watering, to keep over-wintering plants on a dry side. This means, less fertilizer too. This allows you to control elements intake naturally, like you control water amount just as much as the plant needs.

Pretty in Pink... and Purple Prince for her!

By Onika Amell, tropical plant specialist

Q: I have a bare spot in my front garden, behind a low wall, in part-sun. I'm hoping to find an evergreen, flowering ground cover that will cover it quickly. Any ideas on finding something with the ability to eventually also cascade over that wall? I live on Marco Island, Florida.

A: Barleria Repens - Small Bush Violet, is a tough, fast-growing evergreen that blooms from late spring to autumn. Of the many Barleria we see in the tropics, Pretty in Pink is one of the most striking! The name tells the whole story: pretty and pink. A lot of gardeners enjoy using them as a ground cover. They will quickly cover a large area - their stems root readily as the plant crawls along. They are easily propagated by lifting the rooted runners or using cuttings. They also reseed easily. Flowers are followed by seed pots that explode open when dry, dispersing 4 seeds at a time! But perhaps best liked by many gardeners, is their habit to cascade. It will be well suited for covering the bare area in your garden and spilling over that wall beautifully.
When used as a ground cover, remember to pinch out young shoots to encourage bushiness and prune the plant back hard after flowering to keep it neat.
Barleria repens will also adapt to different situations in a garden if you need them to. Although they usually form a rounded to spreading bushy shrub, 2 ft high by 3 ft wide, they will climb when you give them support. They are often allowed to lean into nearby trees and shrubs.
Hardy to 28F, Barleria repens is pest-free and fairly frost-tolerant. They love sun and part shade, as well as well-drained soil and plenty of organic material. Avoid planting it in deep shade as it will get leggy and reluctant to flower.
They will thrive when fed with a slow release fertilizer at intervals of 6-8 weeks, throughout the growing season.

There is another cultivar of this exact variety that has blue-purple flowers, it is called Purple Prince! It couples perfectly with Pretty in Pink! :)

Heavenly Angel's Trumpet

TopTropicals.com

By Onika Amell, tropical flower specialist

Q: Can you please tell me which zones are the best for growing Angel Trumpets? When do they bloom and is there a specific fertilizer to use on them? Do you sell any variegated varieties?

A: If you are lucky enough to live in an area that doesn't freeze or only has light frosts, you can grow Brugmansia (common name Angel Trumpet) outside all year long. They are only entirely hardy in USDA zones 9-12, but they remain very popular throughout the United States. They do really well in coastal settings in the Southwest. They are simply glorious in the coastal areas of South California. In the southwestern states, as well as in the tropics, they bloom spectacularly throughout the spring, summer, and autumn.

Angel Trumpets are very heavy feeders and they need huge amounts of nitrogen. You can use a standard balanced slow-release fertilizer on Brugmansia, but then you must apply it very generously. We've created a specialized fertilizer just for them. Angel Trumpet Delight is a perfect Brugmansia food for frequent monthly feed. It's a 30-day Smart-Release formula that works wonders for Angel Trumpets. A a well-balanced combination of macro- and micro- nutrients with a slow release action, it provides continuous feed, maintains vigor and disease resistance. It also contains coated nitrogen, early release nutrients and extra iron (water soluble and chelated) for quick green-up.

Angel Trumpets come in a dazzling array of colors: orange, yellow, green, white, pink, red, emerald and even purple (closely related Datura). One of our favorites is the beautiful Variegated Orange Angel Trumpet, a new hybrid with variegated leaves and a large single bloom that starts white and turns orange. Another amazing variety is "Sun Explosion" - with a variegated orange flower.

Most folks are usually in awe of the enormous trumpet flowers when they see it for the very first time. They most definitely need to be planted where they can be admired… near a deck, terrace, lanai or, entryway. The blossoms are short-lived, but numerous, continuous, and truly show-stopping! And they smell so good! This is a must have in any tropical garden. They can be grown either as a bush or a small tree. They are easy peasy to grow and root extremely easily, making them great as pass-along gifts for friends. They are sun-loving and super fast-growing plants. Plenty of water and fertilizers keep them happy and at their best. Did I mention they smell good too? ;)

Hardy Plumeria Pudica

Q: I have ordered plumeria pudica from you in March and it is thriving really well here in Rancho Cordova, California. The current temperatures are ranging from 68 to 32 degrees Fahrenheit. My USDA zone is 9b. Does this plumeria pudica survive outside with temperatures dropping in coming winter in CA?

A: From our experience, Plumeria pudica is pretty cold hardy and takes some cold spells in spite of being a tropical species.
Our trees (well-established) took a few hours of freeze with no significant damage.
Potted plants are less hardy than in-ground plants. However, their advantage is, they are easy to move indoors or inside warmer place like garage, etc. If the temperature stays borderline around 32F for a few hours, the plant should be safe as long as warm day temperatures follow a cold night. For longer periods of cold, move the plant inside.
Make sure do not overwater and keep Plumeria on a dry side during winter, since cold and wet is a bad combination and may cause root problems.
Above is the picture of Plumeria pudica tree growing in Cape Coral, FL where low temperatures in winter sometimes go down to upper 20's for a few hours.

To improve cold hardiness of Plumerias and other tropical plants, use SUNSHINE-Epi-T for plant thermal protection and immune system boost.
Make sure to fertilize plants on regular basis to keep them strong and vigorous. The stronger and bigger the plant, the hardier it is!

Fertilizing in Winter?

Q: I'm a bit confused about what winter fertilization schedule I should follow in South Florida. For blooming plants, usually, I use a monthly granular bloom booster fertilizer as well as a liquid fertilizer every 10 days or so. Should I continue that schedule in the winter as well? Should I stop fertilizing altogether in the winter? How about fruit trees? What fertilization schedule should I follow in the winter?

A: Here is a general fertilizing schedule for established plants that we follow here in SW Florida.
The rule of thumb is, do not fertilize (with macro- NPK elements) when minimum temperatures drop below 65F and stay at that level for more than 7 days. At this temperature point, most of the tropical and subtropical plants slow down their metabolism and some of them going into dormancy. This means, nutrients are not consumed as much as during active growth period, and built-up nutrient supply within a plant plus whatever is available in the soil is just enough to get by through the winter. So additional fertilizing is not necessary. You may continue micro-element supplements and bio-stimulants throughout the year. In fact, it is highly recommended to do so, to help the plant survive cold spells. These are very effective tropical plant protectors:
SUNSHINE-Epi - Brassinosteroid plant hormone
SUNSHINE-Power-Si - Advanced plant protector with Silicon
SUNSHINE SuperFood - Complex microelement supplement

This rule is applied to both flowering and fruiting plants, in general. However, some species are winter-flowering and winter-fruiting. For those, you can make an exception and provide extra nutrients for flowering and fruiting, as long as the weather stays warm. During cold spells, avoid any NPK fertilizers and use only bio-stimulants and micro-elements. If you apply NPK during cold, it won't be consumed by a plant, build up in the soil, and may create a root burn situation.

In simple words, fertilize from March to October. Give plants some rest from November to February.
