When the forecast drops into the 30s, panic is not a plan. This is your
simple, clear checklist to protect every tropical in your garden. Think of
it as the quick emergency manual that goes hand in hand with the previous
cold-weather newsletter.
"We
all love our tropical flowers, mangoes, bananas, and rare fruit trees. A
single cold night does
not have to be a disaster. The key is knowing what to do, when to do it, and
what mistakes to avoid." - Tatiana Anderson, Top Tropicals Plant

🌡️ FROST AND FREEZE
A frost and a freeze are not the same. A frost is when you see ice crystals
on leaves or grass, while a freeze is when the air temperature drops below
32 F. The tricky part is that you can get
frost even when the air is above freezing, and you can have a freeze with no
frost at all. It all depends on humidity and the dew point. If the dew
point
is below freezing, the ground can cool faster than the air, letting frost
form even when your thermometer reads 35 or 36 F. And once the air itself
drops below 32 F, even for an hour, tender tropicals can be damaged. For
plants, a freeze is far more dangerous, because freezing air pulls heat out
of stems, branches, and roots. Frost usually burns leaves, but a true freeze
can injure wood, kill buds, and damage the entire plant.

WHAT TO DO
AND NOT TO DO BEFORE A COLD SNAP
✔️ 5 THINGS TO DO:
Water well. Hydrated plants tolerate cold better than dry, stressed
ones.
Add mulch. A thick layer around the base keeps roots warm.
Block the wind. Move pots to a sheltered corner or patio.
Cover at night, uncover in the morning. Let plants breathe and get
light.
Add gentle heat if needed. Non-LED Christmas lights or a small old style
15-20W light can raise temps a few degrees.
❌ 5 THINGS NOT TO DO:
Do not prune or trim. Fresh cuts freeze first.
Do not overwater. Wet, cold soil invites root rot.
Do not let plants dry out either. Wilted plants freeze more easily.
Do not use dry fertilizer. Gentle liquid feeds like Sunshine
Boosters are safe to use with every watering: its intake naturally slows
down as watering decreases.
Do not look only at the thermometer. A long, windy night can be worse
than a short freeze.
TEMPERATURE
ACTION GUIDE (40 to 25 F)
40 to 38 F: Move potted plants to shelter, water soil, and cover
tender tropicals.
37 to 33 F: Use frost cloth and anchor it down so the wind does
not lift it.
32 to 30 F: Add a heat source like non-LED lights.
29 to 25 F: Double-cover sensitive plants, wrap trunks, and
protect roots heavily.
COLD
TOLERANCE BY PLANT TYPE
Before a cold night, it really helps to know your plant’s exact
cold limits. Every species is different, and young plants are always more
sensitive than mature ones. Take a few minutes to look up your varieties in
our Tropical
Plants Encyclopedia
— it will tell you the safe temperature range, how much protection
each plant needs, and which ones must be covered or moved before the next
cold snap hits.
Bananas: leaf burn below 37 F
Mango, Annona: hurt around 32 F
Cold hardy avocados: Mature tree can take about 25 F. Young trees must
be protected
Olives, Citrus, Guava, Jaboticaba: usually OK outside with mulch
QUICK-ACTION
TABLE
Before the cold arrives, make yourself a quick list of every plant and
what action each one needs. It saves time when temperatures start dropping
and keeps you from scrambling in the dark. Check that you have enough frost
cloth, blankets, and supplies on hand so you can cover everything without
rushing. Planning ahead makes cold nights much less stressful.
Bring Indoors: Cacao, Bilimbi, Coffee. They need warm, bright
light.
Cover Outdoors: Mango, Jackfruit, Banana, Annona. Use frost cloth, not
plastic on leaves.

GADGETS AND
TOOLS THAT HELP
Indoor helpers: LED lights, small heaters, bottom-heat mats,
timers.
Outdoor helpers: frost cloth rolls, mini greenhouses, non-LED Christmas
lights or small incandescent lights, smart thermometers.
Always keep electrical safety in mind, especially if you are using extension
cords outdoors. Use only weather-rated cords, keep all connections off the
ground, and protect plugs from moisture. Make sure heaters and lights are
stable, secured, and never touching fabric covers. A few minutes of safety
check
can prevent a dangerous situation on a cold, wet night.
And if you want to keep plants strong through winter, add Sunshine
Boosters to your watering routine. It is gentle, safe in cold weather,
and gives plants an extra edge.
AFTER THE
COLD PASSES
In the morning, uncover plants. Leaving covers on during the day can trap
heat and cook the tender new growth, especially under the sun. The only
exception is true frost cloth designed for all-day use, which allows air,
light, and moisture to pass through. Regular blankets, sheets, and plastic
must come off as soon as the sun rises.
Do not cut anything yet. A plant can look completely dead after a freeze,
but many branches are still alive under the bark. Cutting too soon removes
wood that would recover on its own. Wait until new growth begins in spring.
That is when you can see exactly which branches are truly dead.
Use the scratch test. Gently scratch the bark with your nail or a small
knife. If the layer underneath is green, the branch is alive. If it is brown
and dry, it is likely dead. But even then, wait until warm weather to be
sure, because sometimes only the tips die back while the lower part of the
branch survives.
Once the weather stabilizes, resume light feeding. Plants coming out of cold
stress need gentle support, not heavy fertilizer. A mild liquid feed like
Sunshine
Boosters helps them rebuild roots and push new growth without burning
tender tissue.
Your tropical garden can survive any cold night if you prepare right. Cold
snaps always feel stressful in the moment, but once you know your plants,
have the right supplies, and follow a simple plan, it becomes routine. A few
minutes of preparation before dark can save months of growth and keep your
collection healthy all winter.
Frost cloth is the true workhorse of cold protection: it keeps heat in,
keeps frost off, and will not suffocate plants the way plastic or blankets
can. Having a few rolls ready means you never have to scramble at the last
minute. Sunshine
Boosters give your plants gentle support during the colder months so
they stay strong enough to bounce back quickly when warm weather
returns.
A little planning now will pay off in spring, when your mango, banana,
citrus, and all your favorite tropicals come back happy and ready to
grow.
Sapodilla - Manilkara or Achras zapota, the Brown Sugar Fruit
🍊 How to make Sapodilla fruit profusely?
Sapodilla - Manilkara or Achras zapota), the Brown Sugar Fruit is a warm-climate evergreen fruit tree that can produce a lot of fruit once conditions are right. So why do so many sapodilla trees grow beautifully, flower heavily, and still refuse to set fruit?
Sapodilla Fruit Production - What Really Matters
1. 🌳 Choose the Right Tree
Grafted or air-layered trees fruit much sooner - typically in 1-2 years - and more reliably than seedlings, which may take 6–8+ years.
Some varieties are more profuse producers than others. For example, Silas Woods is virtually everbearing, Hasya is commercial prolific producer, Oxkutzcab (or Ox) -is also heavily productive (learn more about varieties).
2. ☀️ Environment: Heat, Sun & Water Balance
Temperature and Humidity
Excessive heat above 90F and low humidity can cause flowers to dry up and fall before setting fruit.
Solution: Provide filtered light or shade during the hottest part of the day to reduce heat stress on blossoms.
Water
Sapodillas are drought tolerant, but consistent moisture during flowering and fruit set improves fruit retention.
Avoid waterlogged conditions - soggy soil can stress roots and reduce yield.
Sun Exposure
Full sun is best for growth and flowering - but for hot climates, protection during peak afternoon heat helps reduce flower drop.
Young trees can also suffer sunburn.
3. Fertilization: Feed for Fruit, Not Just Foliage
Good nutrition is critical for flowers to turn into fruit. Apply a routine feed through the growing/flowering season - contolled-release (Green Magic) or liquid (Sunshine C-Cibus) both work.
Balanced fertilizer with trace elements like Boron (B), Molybdenum (Mo), Iron (Fe), and Copper (Cu) is essential for fruit set and development. Boron & Molybdenum deficiency as a frequent cause of flower/fruit drop in container-grown trees (nutrients get depleted quickly in pots).
Micro-nutrient sprays 2-3 times per year help improve fruit retention and quality. Some growers use sugar boosters (Sunshine Honey) or micronutrient blends that include Mo & B to help fruit set (Sunshine Superfood).
4. 🐝 Pollination - Often Overlooked
Sapodilla flowers are small and often require pollinators for best fruit set.
In some regions, small insects like thrips are key pollinators.
In places with low insect activity, hand pollination dramatically increases fruit set - brushing pollen from one flower to another with a small paintbrush during peak bloom times can help.
Placing fruit scraps (apple peels/banana peels) under the tree to attract beetles is an inexpensive way to boost insect activity.
5. ✂️ Pruning and Tree Structure
Moderate pruning can help open the canopy for better light penetration and air circulation, which supports flowering and reduces stress. Training young trees promotes a strong branch structure that can carry more fruit later. Sapodilla flowers on young growth (tips of the branches).
6. Pot vs Ground: Size Matters
If your sapodilla is in a container, root bound trees struggle with fruit set because roots run out of space and nutrients - stepping up to a larger container or planting in the ground can help.
Root-bound trees often bloom but fail to develop fruit.
7.
📅 Patience & Timing
Even healthy trees can take years to start fruiting well.
Trees often flower repeatedly but only set fruit when environmental conditions and pollination align - especially important for young or newly planted trees.
📌 Summary Checklist for Better Sapodilla Fruiting
✔️ Choose a grafted variety (faster, more reliable fruit). ✔️ Manage heat & humidity - shade during hot hours. ✔️ Water consistently but avoid waterlogging. ✔️ Fertilize balanced NPK + micronutrients (include B & Mo). ✔️ Encourage pollination
Spring is coming, plants need food!
Time to fertilize...
Last winter was long and snowy in the most part of our
country. Hold on fellow gardeners up North, it is almost
over!
Here in Florida we have been blessed again with a mild
winter without serious cold snaps. Early Spring that is
already in the air. Look at this picture of flowers in our
front yard now.
If the weather is already warm in your area (low
temperatures above 55), it is time to start fertilizing.
We are sending our love and support to tropical Puerto
Rico suffered from hurricane last year, and will be happy
to help you guys to restore your lost gardens!
CHECK LIST
what
to do to give your garden a good kick start:
1. Slow release granulated food. Apply Slow Release Fertilizer and
continue once a month. 1 tsp per gallon of pot, or a
handful for in-ground plants. This will provide essential
macro elements (NPK) required for a plant growth.
2. Water soluble micro-elements. Besides
macro-elements, plants need many other elements that most
of the time missing in soil. A lack of micro-elements
causes different deficiencies, resulting in weak root
systems, slow growth, deformed leaves, leaves yellowing,
lack or no flowers/fruit. Apply these supplements as a
foliar spray once a month to induce healthy growth and
flower/fruit development. We recommend the following
micro-element products to keep your plants healthy and
vigorous year round:

landscape applications.
b) SUNSHINE-Micro - Microelement
booster - for common iron deficiency (pale leaves)
c) SUNSHINE-Super-Iron -
Microelement booster - for severe iron deficiency
(severe yellowing leaves)
3. SUNSHINE plant boosters -
SUNSHINE-E, -BC (caudex plants and bonsai), -H (house
plants). Apply these natural plant stimulants to
help plants recover from cold, dormancy, increase plant's
metabolism and make a plant more readily absorb both
Macro- and Micro-elements. SUNSHINE boosters also will
help plants grow vigorously, withstand Summer heat and
drought, and produce bigger and better flowers and fruit.

Prepare your plants for Winter with Sunshine Boosters
We usually stop using dry slow-release fertilizers from November to March. However,
liquid Sunshine Boosters, which are natural plant food, can be used all year. They help your plants survive winter. When it gets colder, we water less,
so the fertilizer decreases too. The plants only use what they need. To learn more about how Sunshine Boosters work and why they're safe and helpful, check
out this blog: Using Sunshine Booster during Winter.
