When to apply super boost?

Q: Just wanted to know best time of day to apply super boost as spray and watering? Only listed to make sure night temp doesn't drop below 65F...

A: As a rule of thumb, plant's needs in fertilizers are very low in the cold season because they consume less nutrients during dormancy. For tropical plants, when minimum temperatures drop below 65F - we stop applications of dry (granulated) fertilizers until spring, to avoid root burn.
Liquid Sunshine Boosters are exceptions from this rule to a certain extent, for 2 reasons:
- they are amino-acid based which means, salts do not build up in the soil, and thus will not burn the roots even with slower plant metabolism.
- concentrations/formulas are mild and designed for as frequent as daily watering

1) When a plant goes into full dormancy (drops leaves and does not show any new growth), you may stop fertilizing with any Macro NPK products (both dry and liquid)

2) If a plant is evergreen and continues growing during the cooler period, and especially if it is a winter bloomer, mild liquid fertilizers can be applied, depending on the stage of plant development.
Robusta and TotalFeed are used for vegetative growth and pre-flower.
Megaflor and C-Cibus are used for winter flowering/ fruiting plants during the bloom stage.

3) Micro-elements can be used all year round for all plants that are not dormant (do not drop leaves)

4) Always use Sunshine-Epi as a foliar spray to activate immune system and unlock protective mechanisms, BEFORE applying other boosters. It is especially important during Fall-Winter for improving cold tolerance and disease resistance.

5) Always apply foliar spray and/or drench the soil with solutions in morning hours so the plant has time to process the nutrients during daylight when metabolism is the most active.

6) Avoid any dry fertilizers during winter

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.

How to make leaves green?

Q: I purchased several plants from you and they all arrived in great shape. The Wrightia is very large and vigorous but some leaves are yellowish. How can I improve that look? Any special fertilizer?

A: Wrightias are very showy and beautiful plants, although sometimes they are susceptible to leaf chlorosis which in other words is iron deficiency, especially during wet rainy weather. It is not harmful to the plant and can be corrected with microelement applications. Use Microelements once a week to correct the iron deficiency that usually goes away within a month. Then maintain plants health with monthly applications. It is beneficial to use microelements in combination with regular applications of health boosting fertilizer.

Recommended boosters and microelement supplements:

Pink N Good Daily Plant Food - Flower Booster
Tropical Allure - Smart-Release Booster
SUNSHINE SuperFood - plant booster
SUNSHINE-Greenleaf

See SUNSHINE Boosters page for the complete list of plant boosters.

Synergy of SUNSHINE, biostimulants, and macro-micro

Q: I've heard that plants grow better and bigger with SUNSHINE boosters and when using Myco-Mix instead of regular soil mix. Do they work like fertilizers? If I use a Myco-mix, do I still need a fertilizer?

A: SUNSHINE boosters are not fertilizers, they are natural plant hormones, or biostimulants, as well as Myco-Mix which is a naturally occurring compound or microbes. Biostimulants are becoming increasingly attractive to folks interested in sustainable agriculture, and very popular for plant growth or pest resistance. A plant biostimulant is not a fertilizer because it provides no nutritional value to the plants. But, it can promote greater nutrient and water use efficiency, increase resistance to pests and diseases, reduce abiotic stresses, and in turn, lead to plant growth and health.

To answer your question, you can not replace regular fertilizers (NPK) and micro-elements with plant boosters and stimulants. However, fertilizers and microelements will work more efficiently when used in combination with biostimulants. Together they create a synergy, so plants use the most of fertilizer's potential, and will grow a lot better, faster, and healthier.

4 components for the best growing results

1. SUNSHINE boosters. They are a must during the juvenile stage of plant development - seedlings and cuttings. They are especially important for recovery of weak or stressed plants (boosting their immune system).
2. SuperFood microelements
3. NPK fertilizers. Select from water-soluble and smart-release types and make sure do not exceed the recommended concentration. Lower dose and more frequent use is always better for a plant.
4. Specialized soilless mixes: Myco-Mix (with biostimulant Mycorrhiza) for exclusive growing projects and special/unique plants, Professional potting mix for potted plants, and Propagation mix for seeds and cuttings.
