❄️ 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.

🌈 Adeniums: More Than Just Plants

🌱 Shape, Color, and Why Each Adenium Feels Unique

Adeniums can stop you in a strange way. It is not only the flowers, although they help. It is the whole plant. The swollen base, the curves, the way no two look quite the same. Some are thick and heavy, some more refined, almost like they were shaped on purpose. After a bit, you stop seeing them as regular plants and start treating them more like objects you want to keep and look at.

That is usually how a collection starts. One plant, then another that feels different, and then you want contrast. Light next to dark, soft next to bold, one with a wide base next to a taller form. It is not really about having many. It is about how they look together. And over time, each one changes a little, so the collection never stays the same.

*️⃣ Stop Babysitting Your Trees - Grow Cold Hardy Avocados Instead

You always wanted an avocado tree. Not in Miami - right there in Central Florida, in your own yard. You planted one, it grew well for a few years, and it felt like you finally figured it out. Then 2026 hit. A few cold nights, temperatures dropped below what your area usually sees, and the tree was gone.

Here is the part most people miss: USDA zones are based on average minimums, not the worst freezes. One bad night can erase years of growth.

That does not mean avocado will not work. It means you planted the wrong variety. Cold hardy avocados are built for exactly this kind of surprise.

This USDA Zone map makes one thing clear: all of Florida can grow avocado. The question is not if - it is which variety. From North Florida (8b) to South Florida (11a), there is always an option that fits your conditions.

If you are outside Florida - in Texas, Louisiana, California, or anywhere else - the same rule applies. Start with your USDA zone, then choose the right type of avocado for it. You can check your local zone here

So what does this mean for your yard? It is not about trying again and hoping for a warmer winter. It is about choosing a tree that actually matches your zone.

Cold Hardy Avocado Varieties for Reliable Harvests

Microclimate matters more than your zone. The same yard can have warm and cold pockets. Plant near a south-facing wall, under light canopy, or in a spot protected from wind, and you gain a few critical degrees on cold nights.

Young avocado trees need protection during their first winters. They have not built enough wood or root strength yet, so even a short cold snap can damage them. Simple steps like frost cloth, wind protection, or temporary covers can make the difference between a setback and a loss.

You may see avocados labeled as Type A or Type B. This refers to how the flowers open, not cold hardiness. Some people mix both types to improve pollination, and while a single tree can still produce fruit, having two different types is beneficial and can increase your harvest.

Practical Planting Advice

• Plant on a mound
  Raise the root zone 4-8 inches for fast drainage.
• Avoid low spots
  Standing water is worse than drought for avocados.
• Full sun
  Maximum light = stronger growth and better recovery.
• Use microclimate
  South-facing wall, light canopy, or wind protection adds critical warmth.
• Do not overwater
  Let the top layer dry slightly between watering.
• Protect first winter
  Cover young trees during cold nights.

✅ Stop Guessing. Plant What Works.

Cold hardy avocados are not theory - they are proven to handle real conditions. Choose the right variety for your zone, plant it correctly, and you stop replacing trees after every cold snap.
