❄️ The Hardiness Report: February 2026 ❄️

🐾 Smokey & Sunshine’s real-world survival data from our Sebring, Florida Research Gardens. Smokey analyzed the data. Sunshine just stayed happy. Here is what they found.

📊 Weather Data – February 1–6, 2026

Sebring, Florida – 132 years of recorded observations
This was not a light frost. It was a prolonged, windy, penetrating hard freeze.

• 🌡 Minimum temperature: 25F
• ❄️ Wind chill: 14F
• ⏳ Duration: 3 nights of 8–10 hour hard freeze
• ☀️ Daytime temperatures: around 50F for 7 days
• 🌀 Wind: sustained 20 mph, gusts 40–50 mph

While all our plants in pots were protected in greenhouses, our in-ground plantings faced the freeze outdoors. We covered what we could. Even so, some plants were damaged, some died, and some surprised us by surviving.

In the next few newsletters, we will share the real survivors - the plants that proved themselves in the ground, under real conditions. Smokey and Sunshine have been out in the fields assessing the damage from the February 1–6 freeze. While many plants struggled, the Macadamia proved to be a true standout. This is how we grow them to handle the tough years.

Why does this matter? Because we have gotten used to warm winters, and this freeze was a rude awakening. Not everyone lives in Miami. If you garden in places where a real cold event can happen, you have to be prepared - and you have to plant what can take it.

🌰 Macadamia: Freeze Tested and Standing

When temperatures dropped to 25F with wind chill near 14F, our established macadamia trees remained upright, green, and structurally intact. Leaves held. Branches stayed firm. No collapse, no panic.

That is not luck. That is macadamia hardiness.

Often considered a "tropical luxury nut," macadamia proved it can handle more than many gardeners expect. In USDA Zones 9b-11, with proper drainage and site selection, it is not just ornamental - it is a long-term food tree with real resilience.

In a winter that reminded us not to take warmth for granted, macadamia earned its place on the survivor list.

The nut itself is famous for its strength. The shell is among the hardest in the nut world, requiring serious pressure to crack. Inside, the kernel is creamy, buttery, rich, and deeply satisfying. High in monounsaturated fats and naturally low in sugar, macadamias have long been valued both for flavor and for nutrition.

The tree is equally impressive. An evergreen with tough leaves and elegant spring flowers, it matures into a productive, manageable canopy. Nuts develop slowly over six to seven months. Production begins in a few years and increases steadily as the tree matures. Plant it once, and it can reward you for decades.

Cold will come again. It always does. The question is not whether winter will test your garden. The question is whether your trees are ready. Macadamia proved it is. If you are building a garden that feeds you for decades, this is a tree worth planting.

🌞 Spring Nutrition Strategy: How to Identify and Fix Plant Nutrient Starvation

Fellow gardeners,

Spring has arrived, and plants are coming back to life. New shoots are appearing, fresh leaves are unfolding, and roots are beginning to grow actively again. As plants enter this important stage of the season, they need more than just water to support their growth. Proper nutrition is essential for strong development and healthy plants. SUNSHINE Boosters provide the balanced nutrition plants need to start the growing season strong.

A simple rule we follow in our nursery: new growth responds best to foliar feeding. When nutrients are sprayed directly on the leaves, plants can absorb them quickly and efficiently.

• Immediate action – nutrients are absorbed through the leaves and start working right away.
• No delay traveling through soil – plants do not need to wait for nutrients to move down to the roots.
• Avoids soil lockout – micronutrients can become unavailable in high pH soils, but foliar feeding bypasses this problem.
• Supports stressed plants – when roots are cold, damaged, or newly transplanted, foliar feeding helps plants recover faster.

However, sometimes plants begin to show visible nutrient deficiencies. Yellow leaves, slow growth, brown leaf edges, or distorted new leaves are often early signs that the plant is missing essential elements needed for healthy development.

These symptoms are especially common in container plants, where nutrients can be quickly depleted or become unavailable due to soil pH and watering conditions.

Use the quick reference table below to identify common nutrient-related symptoms and the recommended SUNSHINE solution to correct them.

🌿Foliar Feeding: How Much and How Often

For most plants, foliar feeding works best when applied lightly and regularly during active growth.

• Regular feeding (maintenance): Mix with tap water according to the ratio on the label. For SUNSHINE Robusta use 25 ml (5 tsp)per gallon of water and spray leaves every 5-7 days during active growth.
• Correction feeding ("medicine" dose): if plants show visible nutrient deficiencies, combine SUNSHINE Robusta with SUNSHINE Superfood and spray every 5–7 days until new growth appears healthy. All SUNSHINE Boosters products are compatible and can be mixed with water in the same sprayer.
• Best time to spray: early morning or evening when temperatures are cooler and leaves can absorb nutrients efficiently.
• Important: spray both the top and underside of leaves for maximum absorption.

SUNSHINE Boosters: The Professional Advantage

By Tatiana Anderson, Horticulture Expert at Top Tropicals with Smokey & Sunshine help

Here is why SUNSHINE Boosters are the smart choice for your garden this spring:

• Amino Acid Stability: Unlike traditional fertilizers that use synthetic EDTA chelators, our formulas are amino-acid based. This means 100% of the nutrients are bioavailable and consumed by the plant, leaving zero toxic residues or salt build-up in your soil.
• Safe for Every Watering: Because our concentrations are scientifically balanced and mild, they are safe for daily use. This eliminates the "feast or famine" cycle of dry fertilizers and prevents accidental root burn.
• Pure Taste for Edibles: Our delicate formulas do not contain excess salts, urea, or ammonium salts that can ruin the flavor of your harvest. Your fruit and vegetables will retain their pure, natural taste.
• Pollinator Friendly: Our boosters are designed to be safe for honeybees and other beneficial insects, making them the responsible choice for an organic-style garden.

🌿For Potted Plants: Breaking the "Foodless" Cycle

Container-grown plants are trapped in soilless mixes (peat, bark, perlite) that are structurally great but naturally nutrient-deficient.

• Total Nutrition: Since pots lack the natural "buffet" of the ground, SUNSHINE Boosters™ provide every essential mineral the plant cannot find on its own.
• No Salt Build-up: Our amino-acid based formulas are consumed entirely by the plant, leaving zero toxic residue or root-burning salts behind.
• Daily Safety: Our mild concentrations eliminate the "feast or famine" cycle of dry fertilizers, making them safe for use with every single watering.

For In-Ground Plants: Unlocking the Soil

Even in the ground, plants often struggle to absorb what they need because soil compounds can "lock up" nutrients.

• Enhanced Solubility: SUNSHINE Boosters create a slightly acidic environment that helps dissolve stubborn salts in the soil, making them accessible to roots again.
• Precision Delivery: We provide mobile elements like Nitrogen precisely when the plant needs to push new spring growth.

🌿The Foliar Advantage: Direct-to-Leaf Delivery

Did you know a plant leaf can absorb nutrients even more efficiently than the roots? Foliar feeding is your "emergency button" for instant results.

• Quick Fix: Foliar applications with Sunshine Superfood are the fastest way to correct yellowing leaves or visible deficiencies.
• Metabolism Boost: Sprays like SUNSHINE-Epi act as a bio-regulator, helping plants recover from the stress of spring temperature swings.
• Better Fruit: SUNSHINE Honey is applied to leaves to naturally move sugars to the fruit, increasing sweetness and flavor.

🌿The Calcium Problem: Solved

As your plants wake up this Spring, they need structural strength. Think of Calcium as the "cement" that holds plant cells together. Without it, new spring growth is doomed to fail.

Signs Your Plant is Starving for Calcium:

• Deformed Leaves: New growth looks twisted, hooked, or curled.
• Blackened Tips: The very edges of young leaves turn white, then quickly blacken and die.

The Industry Secret: The "Missing" Mineral

Most fertilizers, both dry and liquid, completely skip Calcium. Why? Because it’s a chemical nightmare to keep stable in a concentrated solution. Most manufacturers rely on your irrigation water to deliver Calcium, but tap water is inconsistent and often fails to provide what a hungry, growing plant needs.

The SUNSHINE Boosters: Stable Calcium in Every Bottle

We have successfully stabilized Calcium directly into every single Sunshine Booster formula. Whether you are using Bombino, Robusta, or Megaflor, you are delivering a precise, stable dose of Calcium with every watering. No lockout, no sediment, and no relying on the "luck" of your tap water. Just strong, healthy cell walls and perfect spring growth.

🌿SUNSHINE-Epi: The Year-Round Bio-Regulator

Whether it’s the transition of spring, the extreme heat of summer, or the dry air of indoor wintering, SUNSHINE-Epi is your plant’s primary defense. This natural Brassinosteroid acts as a powerful immune booster, helping plants navigate stress wherever it comes from.

• Universal Stress Shield: Protects against temperature swings (both heat and cold), drought, and transplant shock.
• Vigorous Development: Dramatically improves root growth and speeds up the metabolism of young seedlings and cuttings.
• Eco-Safe: 100% non-toxic to humans, pets, and pollinators.

Note: While Epi is highly effective, it is a performance booster, not a substitute for proper care. It works best when paired with the right light, water, and a consistent feeding program. It won't bring a dead plant back to life, but it will help a struggling one find its footing.

❓Frequently Asked Questions: SUNSHINE Boosters™

• What water should I use for foliar spraying?
  Tap water works perfectly for most. However, if your water is very "hard" (leaving white mineral spots on leaves), switch to distilled water for a cleaner finish and better absorption.
• How long does a diluted solution last?
  For maximum potency and to avoid nutrient degradation, try to use your diluted mixture within a few hours of preparation. Keep away from direct sun. Fresh is always best!
• Can I use SUNSHINE Boosters as a daily foliar spray?
  Yes! You can mist your plants daily to maintain high vigor, but you must reduce the dosage (use half the recommended strength) to avoid over-feeding.
• Can I mix boosters with pesticides or fungicides?
  It is best to apply them separately. Mixing fertilizers with chemical pesticides in one tank can trigger reactions that "lock out" nutrients or reduce the efficacy of the treatment.
• Will the liquid stain my patio or hands?
  No. Unlike traditional fertilizers with heavy blue or pink dyes, our solutions are clear or very light-colored. If you spill it, simply rinse with water—no stains, no mess.
• Can I mix different SUNSHINE Boosters together in one sprayer?
  Yes. All SUNSHINE Boosters are chemically compatible. You can combine a "growth" booster like Robusta with a "micro-element" complex like Superfood in the same water to save time.
• Are these products safe to use around my pets?
  Absolutely. Our formulas are 100% non-toxic and amino-acid based. Just ask Smokey and Sunshine—they are perfectly safe for households with curious cats, dogs, and children.
• Can I use these boosters on indoor plants?
  Yes. They are ideal for indoor use because they don't produce a "fertilizer smell" and won't cause salt crusting on your decorative pots or furniture.
• Is it safe to use on fruit and vegetables I plan to eat?
  Yes. Because our formulas contain no urea, nitrates, or harsh salts, they don't leave a "chemical" aftertaste. They actually help improve the natural sugars and flavor profile of your harvest.
• What is the best temperature for foliar spraying?
  Apply when temperatures are below 85°F. Early morning or late evening is best; this allows the leaves to remain wet longer, giving the plant more time to absorb the nutrients.
