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.

When plants are ready for a meal?

Q: We have an early Spring here in Florida. All plants in my garden flushing out new leaves and buds opening. Can I start fertilizing? I have Mango, Avocado, Peach trees, many medicinal herbs and flowering shrubs: Angel trumpets, plumerias, bromeliads. I prefer mild organic fertilizers; can you suggest something that is safe for edibles and butterflies?

Q: As a rule of thumb, tropical gardeners start regular fertilizing when the minimum temperatures (at night) go above 65F. Keep in mind that Sunshine Boosters fertilizers can be applied year around because they have mild formulas and used with every watering; during cooler period, you water less frequently, so feeding is reduced accordingly. Another advantage of Sunshine Boosters - they are natural (derived from organic amino acids which is the basics of Life). They are safe for edibles as well as pollinating insects.

Here is the feeding plan for your plants:
1. The most universal solution for all plants (both potted and in-ground): get a complete set of Sunshine Boosters Pro system: Advantage-Pro for vegetative growth, BloomBoom Pro for flowering stage, and Ca-Support-Pro + Constanta-Pro as necessary daily supplements. You will need all these 4 components for your garden.
2. Start adding these liquid boosters with every watering according to dozing directions and you will notice amazing growth boost within a week.
3. Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost immune system and metabolism of plants and protect them from diseases. Epi makes plants (especially young plants and those "waking up" from dormancy) grow twice faster! It also enhances effect of fertilizers by increasing plant metabolism.
4. After cool winter temperatures, some plants may develop element deficiencies like chlorosis (yellowing leaves). Additional microelement boost can be provided with Sunshine Greenleaf (iron supplement) and Sunshine Superfood (micro-elements).
5. For additional boosting of flowering and setting fruit, use the following individual boosters:
Sunshine Robusta - for foliage plants and when you need rapid vegetative growth
Sunshine TotalFeed - for Plumerias and other fragrant plants
Sunshine Megaflor - for Brugmansias and other flowering heavy feeders
Sunshine C-Cibus - for improving fruit production and quality
Sunshine Honey - for sweeter fruit (must be applied 4-5 times a year)
6. For young/small plants (seedlings, rooted cuttings) as well as tender tropicals like bromeliads, and orchids - Sunshine Bombino is a perfect choice due to its mild formula.
7. To save money, order complete sets rather than individual boosters; you will be able to safe up to 40%! Sunshine Complete Nutrition System Kits: Combo Kit, and Pro Kit.

If you are a fan of organic gardening, do not use dry fertilizers. While water-soluble and granulated (smart-realease) fertilizers are popular choice in plant nurseries due to their convenience, they are not as safe as liquid boosters because they create salt build-up in soil and have a high risk of overdosing/burning plant roots, especially potted plants, plants at breaking dormancy, at establishing, and at early stages of plant development. Besides, dry fertilizers may affect the taste of your fruit and herbs. See advantages of liquid boosters over dry fertilizers.
