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.

Avocado, Lychee and Mango setting fruit... give them some FOOD!

Q: Do I need to fertilize tropical fruit when they set fruit?

A: It is traditionally believed that mango and other tropical fruit shouldn't be fertilized during fruiting period. It is true to an extent: you don't want fruit to burst from fast excessive growing. Instead, try to feed fruit trees wisely, because they still need proper nutrition to produce flowers and fruit.
Our spring specials of Lychee, Avocado and Mango are full of buds and some already set tiny fruit (see examples on the photo). Here is the feeding plan for these plants once you receive your mail order:
1) Once received the plant, pot it into container size of the root ball and let establish for couple weeks. Use SUNSHINE-E to help the plant recover from shipping stress and establish root system.
2) Apply SUNSHINE-Honey right before flowering, and next time at setting fruit, to provide sweeter and bigger fruit, eliminate fruit cracks and help resist fungus and other fruit diseases.
3) Use balanced granulated fertilizer, 1 tsp per each gallon of soil. Apply once a month during Spring-Summer season. This gives the plant balanced macro-elements (NPK) necessary for overall plant health. Do not use on fruit trees fertilizers with high Nitrogen content.
4) Apply SUNSHINE SuperFood micro-element booster to keep fruit trees vigorous, develop strong root system and avoid deficiencies.
5) In case of signs of chlorosis (yellowing leaves with darker veins), give the tree SUNSHINE-GreenLeaf and watch the leaves turning green quickly.
After harvesting, don't forget to make another treatment of SUNSHINE-Honey as a preparation for the next year flowering and fruiting season.

Edible Landscape: fruit bearing hedge

Photo above: Biquinho Pepper (2 months old plant)

Q: My mom had to remove a hedge for some renovations and after being heartbroken about losing my little bird haven, I've decided to plan on a fruit bearing hedge that offers some privacy and places for the little fledgling to wait for food. Any suggestions? I was thinking blueberries or citrus but open to any ideas.

A: Below are a few suggestions for a fruit bearing hedge planted with fast-growing, tropical species. They will contribute to a nice edible landscape for both your family and the birds - they will be very happy!

Larger size hedge (small trees), grows full-size within 1 season:
- Loquats
- Dwarf Mulberries (very cold hardy too) such as Dwarf Everbearing

Medium size hedge (shrubs or vines), 2-3 seasons to grow full size:
- Black Surinam Cherry Lolita
- Blackberries and raspberries

Low hedge (4-5 ft tall, 1 season, fast growing):
- Biquinho Pepper
- Wiri Wiri Pepper

Citrus is probably not a good idea, not bird's favorite, and blueberries require a special acidic soil here in Florida, so they will need extra maintenance, special soil, and heavy mulching.

Q: How can I get a list of plants that do well in coastal areas (i.e. next to sea)?

A: Many tropical plants live by the sea in natural habitat and don't mind ocean breeze. We have a large selection to pick from. The following groups of spectacular flowering trees will enjoy coastal environment:
Cordia trees
Plumerias
Orchid trees (Bauhinias)
Caesalpinias
Callistemons (Bottle brush trees)
Cassias
Many palm trees
