❄️ 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.

Avocado pollinating and crops

Avocado  fruit

Q: I bought an anise leaf-scented avocado from you, and it is finally quite large and doing great. I live in California, the coldest temperatures we seem to get in some winters is around 25 to 28F, and it never lasts long. The tree might get a bit of frost nipping on the new growth, but it has done very well. It has flowered profusely for the last two years but hasn't set any fruit. What variety you might recommend to help with pollinating?

A: We are glad your avocado is doing great. Anise is one of our favorite varieties, with the wonderful smell of leaves and tasty fruit.

Cold hardiness and flower quality

It is true that cold damage may affect avocado production, especially in setting fruit. To improve the tree's cold hardiness, make sure to provide balanced plant food, especially during the season of active growth. For our avocado trees, we use Sunshine C-Cibus year-round.

If you prefer to use dry (granulated, slow-release) fertilizers, make sure they contain micronutrients, or apply Sunshine Superfood microelement complex once a month.

To improve flower quality (including the ability to set fruit), we recommend a special micronutrient supplement called Sunshine Honey. It contains Boron and Molybdenum - elements that are responsible for setting fruit and for developing fruit (meaning not dropping at the early stage of development).

Cross-pollination and crop

In general, every avocado tree is self-fertile, meaning it can produce some fruit with its own pollen and doesn't necessarily require a second tree for pollination. So even if you don't do anything, sooner or later your tree will set fruit. However, it is also true that the amount of fruit and crop reliability depends on pollination factors. One type of avocado classification is by flowering and pollination behavior - type A or B.

When both types of trees are grown in proximity to each other, their overlapping flowering patterns significantly enhance the chances of cross-pollination. This can lead to improved fruit set and higher yield, making it especially important for commercial production and, to a lesser extent, for home growers.

Therefore, it's advisable to plant different varieties of avocado in your garden - the more, the merrier! The greater the diversity of avocado trees with overlapping flowering periods, the better your crop is likely to be. If you're growing an avocado tree without other avocados nearby, it becomes helpful to have more than one tree with different flowering patterns (A and B) to increase yield in your garden.

Anise Avocado is type B. So to increase your crop, you may consider planting type A variety from the list: Bernecker, Black Prince, Catalina, Choquette, Day, Donnie, Fantastic, Florida Hass, Lila, Loretta, Lula, Mexicola, Mexicola Grande, Red Russell, Reed, Russell, Simmonds, Ulala , Waldin .

To learn more about avocado types, fruit characteristics, cold hardiness and much more, refer to our Avocado Variety Guide - a page with very convenient interactive chart allowing you to quickly sort types of avocado by requirements of your choice (just click on column header to sort data).

Fertilizer and the Fall Garden

by Ed Jones, the Booster Guy

...Well Labor Day has come and gone. Summer is winding down and depending on where you live, thoughts are now turning to pumpkin spice, witches, fall decor and gardening. Wait, did I just say gardening? Yes, if you live in the deep south, and I do, it is time to think about fall gardening and fertilizer. Even those of you in the north can put in a few quick crops now for fall. Think onions, radishes, lettuce and other greens and of course, garlic...

Next month, we can start putting out our plants that do better in cooler weather. We will put out some beans and of course cabbage. We may do some potatoes too. What do you like to grow?
But what about fertilizer? Glad you asked. Now, most of us have our favorite brand of fertilizer. Some of us had some secret fertilzers that we used in the past. For me it was composted alpaca manure. Yes, we raised alpacas in the north, but that is another story for another day....

...Once the temperatures have begun to drop, it is better to use a good liquid fertilizer. The one I will be using this year is SUNSHINE Robusta. SUNSHINE Robusta is an organic amino acid based liquid fertilizer that is safe to use with every watering. It uses amino acids to chelate (bind) micro-nutrients and makes it easier for plants to take them up from the soil. Most fertilizers use EDTA to chelate their micro-nutrients and plants must use about 4 times more energy to break them down than they do with SUNSHINE Boosters. This means that your plants will have more energy to put into growth. And isn't that what we are after?
With Special Seasonal price for 16 oz bottle reduced to only $19 with FREE shipping, this is your best choice of organic, safe fertilizer for your vegetable garden!..

Healthy Plants: Q&A from Mr Booster

How to prevent mango flowers drop

Q:The mango blossoms my tree had in February have blown off due to weather conditions. Do you know what I can do to prevent this from happening again in the future?

A: The only "guarantee" to protect mango flowers from cold weather damage here in Florida is to plant a LATE flowering variety. Generally, mango trees are winter bloomers. Those varieties called "early season" start flowering in January (for example, Nam Doc Mai), and of course very often they get affected by cold, so they drop. Some varieties are so called "late season" - for example Venus. They start flowering in spring when the weather conditions are more favorable.
Another thing that may help you with mango flower drop is applying plant micro-element supplement Sunshine-Honey - it contains Molybdenum and Boron, which help flower and fruit development/strength and prevent their drop.
