Smokey and Sunshine Prepare Plants for the Cold Night.
Smokey: Come on, Sunshine, help me move these plants inside before it gets
dark!
Sunshine: I am helping... see? I’m supervising the mango
tree.
Smokey: You call that supervising? The frost cloth’s upside down!
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
Expert
🌡️ 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.
Ordering plants in winter is often easier than people expect - and for
many plants, it is actually better. Lush foliage plants like philodendrons
and medinilla,
fine-leaved trees such as moringa, jacaranda,
and poinciana,
and even sensitive fruit trees like papaya, jackfruit
or starfruit
ship more safely in cool weather without
overheating stress.
Winter is also ideal for subtropical and cold-tolerant plants, dormant or
deciduous plants like plumeria and adenium, orchids - including ground
orchids and vanilla
orchids, and winter bloomers that flower their best right now. Winter
care is simple: water less, use gentle liquid amino-acid fertilizers like Sunshine
Boosters, and monitor insects.
In mild climates, many tropicals can be planted anytime, while
extra-tender plants can stay potted until spring. Winter is a
perfect time to bring tropical warmth indoors and enjoy greenery when you
need it most.

🌸 Adenium Care
Basics
Adeniums have many spectacular hybrids, and their basic culture is closer to
orchids than to typical houseplants.
The key is a small pot, excellent drainage, bright light, and careful
watering.
Pot and Soil
Use a small pot sized to the root system.
Excellent drainage is required.
Use a very well-drained mix. We recommend specially formulated for
Adeniums Desert
Rose Soilless Mix
Light and Blooming
Give lots of light for heavy flowering.
In warm conditions and longer days, most hybrids and species begin
blooming in spring.
In warmer climates they can keep blooming through fall and winter.
Watering (Most Important)
Adeniums dislike both extremes: over-watering and drying out too
often.
Use neutral to hard water when possible.
Acidic water can sour the mix quickly and may cause root rot.
Water in the early morning so the plant can drink through the day.
Watering frequency can range from daily to every few days, depending on
heat, light, and how fast the mix dries.
Never let the pot sit in a saucer of water.
Do not let the plant dry out too often, or it may go into early
dormancy.
Do not wet the leaves.
Fertilizer (Caudex + Flowers)
To build a large swollen base/trunk (caudex), use a good quality
fertilizer.
A fertilizer that helps trunk swelling also supports flowering. The best
choice for this is Sunshine
Megaflor.
Avoid fertilizers that are too high in nitrogen; choose a formula where
the middle number is the highest.
Never apply fertilizer directly on roots.
Do not liquid feed a thirsty plant.
Always water lightly first, then feed, to avoid root burn and leaf
drop.
The Caudex "Secret" (Shaping the Base)
At each repotting, lift the plant slightly so the upper roots are a
little exposed.
This encourages new roots to grow downward and helps create a thicker,
more interesting caudex shape.
Multi-Grafted Plants (Important Note)
Adenium hybrids can be multi-grafted with several colors/varieties on
the same plant.
The swollen base forms only when the rootstock plant is grown from
seed.
✍️ Adenium
FAQ
How much light do Adeniums need?
Adeniums need lots of light for heavy flowering. Most hybrids and species
start blooming when conditions are warm and days get longer, and in
warmer climates they can keep blooming through fall and winter.
What is the best pot size for Adeniums?
Use a small pot sized to the root system, with excellent drainage. A small
pot with excellent drainage is a must.
What kind of soil mix should I use?
Use only a well-drained mix. Adeniums do best in very well-drained soil. A
small pot plus excellent drainage is the foundation of success.
How often should I water Adeniums?
Adeniums do not like both over-watering and drying-out too often. Water
preferably in the early morning and do not water again until the mix dries
on the surface. Watering can range from daily to every few days depending on
heat, light, and how fast the mix dries.
Can Adeniums sit in a saucer of water?
No. Never allow your Adenium to sit in a saucer of water.
Should I wet the leaves when watering?
No. Do not wet the leaves.
What kind of water do Adeniums prefer?
Adeniums prefer neutral to hard water. Acidic water tends to sour the soil
too fast and may cause root rot.
How do I create a large, swollen caudex?
At each repotting, lift the plant slightly so the upper parts of the roots
are a little exposed. This encourages the plant to form more roots that grow
downward and helps create a thicker, more interesting caudex.
What fertilizer should I use for caudex growth and blooms?
Use a good quality fertilizer to support both trunk swelling and flowering.
Avoid formulas that are too high in nitrogen; the middle number should be
the highest. Never apply fertilizer directly on roots, and do not liquid
feed when the plant is thirsty. Water lightly first, then feed, to avoid
root burn and leaf drop.
Can an Adenium have multiple flower colors on one plant?
Yes. Adenium hybrids can be multi-grafted with several colors or varieties
on the same plant. Note that the swollen base forms only when the rootstock
plant is grown from seed.

The Magic Number 65: when tropicals finally wake and the 7-Day Rule you should know 🌱
Discover the "Magic 65" rule for waking up your garden and the exact time to start fertilizing for maximum growth. Learn the specific temperature threshold that signals your tropicals to wake up and how to handle spring cold snaps.
🌿 If you’ve been staring at your dormant trees and shrubs wondering if they survived the winter, you aren't alone. The most frequent question every spring is: "When will my tropical plants start sprouting?"
🌿 While the calendar might say spring, tropical plants don’t use a watch - they use a thermometer. If you want to see green shoots and active growth, there is one "Magic Number" you need to watch: 65F 🌡
🌿 The 7-Day Rule for Tropical Growth
The gold standard for the tropical world is simple: plants generally wake up when minimum nighttime temperatures remain at or above 65F for at least one full week.
🌿 Why 65°F?
Tropical species are biologically programmed to stay dormant to protect their cell structure from cold damage. A single warm day won't fool them, but seven consecutive nights of 65F+ signals that the "growing season" has officially arrived. Once you hit that 7-day mark, you’ll see buds pushing and fresh leaves finally sprouting.
🌿 Can You Force Them to Wake Up Faster?
Patience is a virtue, but if you’re looking to "push" your plants, focus on two things:
🌞 Sun Exposure: Ensure they are in the brightest spot possible to warm the soil. ♨️ Heat Retention: Use dark mulch or move potted plants onto concrete surfaces that retain daytime heat.
🌿 When to Start Fertilizing
❌ Don’t reach for the fertilizer until you see that active growth. Feeding a dormant plant can lead to root rot or wasted nutrients.
👉 The Signal: After that first week of 65F nights.
✅ The Action: Once you see green tips, start your fertilization routine. This is when the plant actually has the metabolic "engine" running to use those nutrients.
🌿 Watch Out for the "False Spring"
Before you go all-in, ensure the risk of a hard freeze has passed. A minor cold snap - a few nights in the 50s - won't kill your progress, but it will act as a "pause" button. If cool weather persists, tropicals may "lock up" and return to dormancy. If that happens, simply reset your clock and wait for the next stretch of 65F nights.
🌿 Ready for the Wake-Up Call? Fuel Your Tropical Growth!
Don’t get caught empty-handed when that 7th day of 65F hits. Stock up now so you can feed them the moment they wake up. Using the right nutrients during the active growth phase is key to lush blooms. Check out our curated selection of professional-grade fertilizers:
