❄️ 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.

Sunshine: Twenty five degrees. Wind chill fourteen. And it is still standing... like nothing happened?
Smokey: This is macadamia strength.
Sunshine: I should put a macadamia nut in my coffee and borrow some of that strength.
Smokey: Do not get too nutty yet. It still needs curing and cracking.

📊 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

3 year old macadamia tree after 3 nights of hard freeze in February 2026 - standing strong.

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

Smokey  and  Sunshine  PeopleCats  diagnose  a  starving  coffee  plant  and 
 revive  it  using  Sunshine  Robusta  boosters,  turning  a  weak  yellow  plant  into 
 a  healthy  green  coffee  tree  after  one  month..
Sunshine: I'm trying to fight rising coffee prices. So I planted my own coffee plant. But it's dying.

Smokey: It's not dying. It's starving. Classic nutrient collapse. Imagine going two days without donuts.

Sunshine: Two days? That's a PeopleCats rights violation. Catstitution First Amendment: food, including donuts, must remain available.

Smokey: Exactly. Plants feel the same. Let's feed it. Sunshine Robusta. Robusta is coffee, you know.

Sunshine: Obviously they named Sunshine Boosters after my charm. And since it's coffee, it should work perfectly.

One month later

Sunshine: Holy whiskers! You're a magician.

Smokey: No magic. Just boosters.

Sunshine: Great. Coffee is on me when this tree starts producing. You bring the donuts.

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.

Symptom you see What to do
Pale leaves, slow growth, weak new shoots
(often nitrogen related)
Spray SUNSHINE Robusta to stimulate strong vegetative growth.
Brown leaf edges or weak plant vigor
(often potassium related)
Apply SUNSHINE Robusta to restore nutrient balance.
Yellow leaves with green veins
(iron or manganese deficiency)
Apply SUNSHINE Superfood to correct micronutrient deficiency.
Small distorted leaves or poor flowering
(zinc or boron deficiency)
Use SUNSHINE Superfood during active growth period.

🌿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.
