Improving cold hardiness before winter: fertilizer and micro-elements

TopTropicals.com

Q: I live in New Jersey and it is getting cool here, with temperatures in the upper 40s, but my tropical plant collection is in a heated sunroom (still around 70s). Should I continue fertilizing my plants? And if yes, my second question about deciduous Sugar Apple tree. Should I continue fertilizing it until it drops leaves?

A: First of all, even though you live outside tropical climate, your plants enjoy warm temperatures year round, and can be treated like if they were in a Southern garden.
Plant nutrients, both macro-elements (regular fertilizer) and micro-elements (such as iron, manganese, magnesium, copper, and other elements) play an important role not only in overall plant health but also in plant hardiness.
The rule of thumb is, even in warm climates we cut off any fertilizer by the end of October. You still have time for the last treatment this year (next will be in March, or when your plants start showing new growth). You may apply just a bit of slow-release granulated fertilizer, or water-soluble by foliar spray, diluted 1/2 of label strength, to all evergreen species in your collection.
The most important application before winter is micro-elements and other plant boosters that will help you plant collection survive winter months with a shorter daylight and cooler temperatures. Now it is a perfect time to make these simple steps:

1) Miscro-element applications, any one of: Superfood, Iron Supplement, Greenleaf.
2) Sunshine-T application: for improving cold hardiness, plus immune system resistance to insects and deceases.
3) Sunshine-Honey application for all fruit trees to encourage bigger and sweeter fruit next year.

Regarding your second question. Deciduous tropical plants like Annonas, Adeniums, Plumerias, etc - do not need regular fertilizer at this time, however, go ahead and apply microelements Superfood complex, as well as Sunshine-Honey, while leaves are still green. These two will give a kick-start to provide better flowering in spring, and production of sweeter fruit later.

♊ Gemini Season Starts. We Are Five Days Late. Very Gemini.

Smokey  and  Sunshine  with  Gemini  tropical  plants  in  a  whimsical 
 greenhouse
Sunshine: I once met a girl and asked what she does. She said she assembles gyroscopes. I told her I don't believe in gyroscopes.
Smokey: You meant horoscopes.
Sunshine: That is what I said.
Smokey: You said gyroscopes.
Sunshine: Same thing.
Smokey: One predicts your future. The other stabilizes aircraft.
Sunshine: I don't believe in aircraft either.
Smokey: She left, didn't she.
Sunshine: She said she had to go assemble something.

♊ Gemini season started on May 21. Today is May 26 But honestly? That is not a problem. That is actually very Gemini. Gemini probably got distracted, opened three browser tabs, started a new hobby, forgot what it was doing, and came back five days later with a notebook full of ideas and zero apologies. So here we are.

Why these plants and not others

No, there is no scientific proof that olive trees belong to Gemini. We checked. The olives refused to comment. But if you are going to assign plants to zodiac signs — and we are — then Gemini deserves plants with intelligence, motion, surprise, fragrance, and a little chaos. Gemini is the sign of curiosity, conversation, and dual natures. It gets bored easily and talks to everyone at the party. These plants were picked because they fit that energy. And also because they are genuinely good plants worth growing, which Smokey insisted we mention.

Olive (Olea europaea)

Close-up  of  an  olive  tree  branch  laden  with  clusters  of  green  olives 
 among  narrow  silvery-green  leaves.  The  fruit  is  ripening  on  the  tree  and 
 hanging  from  slender 
 stems.

Clusters of green olives developing on an olive tree branch. Olive trees are evergreen, drought-tolerant, and have been cultivated for thousands of years for both their fruit and the oil produced from it.

Olive is the thinking plant of this group. Ancient, silver-leaved, and quietly dramatic, it belongs to Gemini because Gemini loves history, long conversations, and plants that look like they know something you don't.

If you are growing olive in a container — which works very well — give it full sun, fast-draining soil, and a firm commitment to not overwatering it. Olive does not want wet feet. It wants to think in dry conditions, like a philosopher in a warm courtyard.

Smokey: Olive represents thousands of years of cultivation and human civilization.
Sunshine: And snacks with much better branding than they get credit for.

Dwarf Mulberry (Morus sp.)

Branch  of  a  Dwarf  Everbearing  Mulberry  tree  displaying  fruit  in  various
    stages  of  ripening,  from  pale  green  and  pink  to  deep  purple-black,  against 
 a  bright  blue 
 sky.

Dwarf Everbearing Mulberry produces fruit over an extended season, often carrying berries in multiple stages of ripeness at the same time. The sweet, blackberry-like fruit is a favorite of both gardeners and wildlife.

Mulberry is Gemini in motion. It grows fast, produces generously, and absolutely refuses to be boring. A standard mulberry will take over your yard before you finish reading this sentence. A dwarf mulberry, however, is patio-friendly, container-happy, and still delivers fruit, birds, and mild garden chaos on schedule.

Prune after fruiting to keep the shape. Full sun. Large pot if you're growing in a container. This is the plant for people who want results and do not enjoy waiting.

Smokey: Efficient growth rate. Edible output. Compact habit. Reasonable choice.
Sunshine: Finally, a tree with a snack schedule.

Parijat (Nyctanthes arbor-tristis)

Close-up  of  Parijat  flowers  (Nyctanthes  arbor-tristis)  with  white 
 pinwheel-shaped  petals  and  bright  orange  centers  surrounded  by  fresh  green 
 leaves  and  unopened  flower 
 buds.

Parijat, also known as Night-Flowering Jasmine, produces fragrant white flowers with vivid orange centers that open at night and often carpet the ground beneath the tree by morning.

Parijat belongs to Gemini's quieter, more poetic side. It blooms with small fragrant white flowers — orange centers, delicate petals — often at night. By morning, the flowers have fallen. They drop like little messages from the universe, which Sunshine finds meaningful and Smokey finds botanically interesting.

This one is for the gardener who wants something to actually stop and look at. Good in containers, good on a warm patio, needs decent light and warmth to do its best work.

Smokey: Night-blooming pattern. Fragrant ornamental. Grows well in warm climates.
Sunshine: It's a tree that leaves notes.

Dwarf Golden Tabebuia (Tabebuia chrysotricha)

Dwarf  Golden  Tabebuia  tree  covered  in  bright  golden-yellow  flowers, 
 standing  in  a  lawn  beneath  a  blue  sky,  with  a  carpet  of  fallen  blossoms 
 surrounding  the 
 trunk.

Dwarf Golden Tabebuia puts on one of the most spectacular spring displays, covering its branches with brilliant golden flowers before the leaves emerge. The fallen blooms create a striking yellow carpet beneath the tree.

This is the Gemini show-off. Quiet for most of the year, then suddenly covered in golden yellow flowers like it just remembered it has an announcement to make.

Dwarf Golden Tabebuia is compact enough for a large container or a sunny entrance, but it needs strong light to bloom well. Give it sun. Give it room. Then step back and let it perform.

Smokey: Seasonal flowering response triggered by environmental conditions.
Sunshine: Botanical applause.

Miracle Fruit (Synsepalum dulcificum)

Clusters  of  bright  red  Miracle  Fruit  berries  growing  among  glossy  green
    leaves  on  a  compact  shrub.  The  elongated  fruits  stand  out  against  the  lush 
 foliage.

Miracle Fruit is famous for its unique berries, which contain miraculin - a natural compound that temporarily makes sour foods taste sweet. The attractive evergreen shrub produces bright red fruit and is well suited to containers and small gardens.

Miracle Fruit belongs on this list because it is, without argument, the most Gemini plant in existence. It does not taste like much on its own. But eat one berry and everything sour suddenly tastes sweet. Lemons taste like lemonade. Lime juice tastes like candy. A plain piece of sourdough becomes something you would pay extra for. The fruit literally changes how you experience everything that comes after it.

If that is not Gemini energy — dual nature, transformation, making you see the same thing two completely different ways — nothing is.

Miracle Fruit is a slow grower that likes warmth, humidity, acidic soil, and protection from cold. It does well in containers, which is good news because it genuinely hates frost. Keep it in a pot, bring it in when temperatures drop, and give it filtered light or morning sun rather than harsh afternoon exposure.

Smokey: The active compound is miraculin. It binds to taste receptors and distorts sour perception at low pH. Temporary effect, roughly thirty minutes to an hour.
Sunshine: It's a fruit that lies. Beautifully.

Spanish Tamarind (Wild Medlar, Vangueria infausta)

Spanish  Tamarind  (Vangueria  infausta)  tree  with  glossy  green  leaves  and
    clusters  of  round  fruit  in  various  stages  of  ripening,  from  green  to 
 golden-brown,  growing  on  branching  stems  in  a  lush  tropical  garden  setting.

Spanish Tamarind (Vangueria infausta) may be grown for its unusual fruit, but it also brings beauty to the garden with its lush foliage and heavy crops of ripening fruit. Green and golden-brown fruits often appear together on the tree, creating a colorful display.

Spanish Tamarind belongs to Gemini because it is unusual enough to start a conversation before anyone even knows what it is. The name alone does it. People will ask. You will explain. The fruit changes color as it ripens, the plant has collector appeal, and the whole thing feels like something you found in a book about plants that don't get enough attention.

This one needs warmth, sun, good drainage, and patience. It can live in a container with pruning. It rewards the gardener who is genuinely interested in something a little different.

Smokey: Tropical fruiting curiosity. Suitable for collectors.
Sunshine: Sounds like something I would order at a restaurant without reading the description.

Container  filled  with  ripe  Spanish  Tamarind  (Vangueria  infausta)  fruit

 of  velvety  green  leaves.

One of the traditional uses of Spanish Tamarind (Vangueria infausta) is fruit tea. The ripe fruit can be dried and steeped to make a mild, refreshing drink rich in natural flavor, while the soft, velvety leaves have long been used in traditional herbal infusions.

Horoscope aside — why these plants are actually worth growing

Even if Gemini energy has nothing to do with your garden, these plants offer real value: fruit, fragrance, flowers, container growing, and something interesting to look at or talk about.

  • Olive — full sun, excellent drainage, don't overwater, thrives in containers. Tropical varieties: USDA Zone: 8-10. Cold hardy to 15-20°F.
  • Dwarf Mulberry — full sun, large pot, prune after fruiting, fast results. USDA Zone: 8-11. Cold hardy to 20-25°F. Most mulberry varieties can be grown in USDA Zone 5-6 to 10 and cold hardy to 5°F.
  • Parijat — warmth, good light, patio or container, fragrant and ornamental. USDA Zone 9-11. Tolerates light freezing to about 30°F for short periods (mature plants). Young plants must be protected.
  • Dwarf Golden Tabebuia — strong sun, large container or sunny ground spot, compact but dramatic when it blooms. USDA Zone 9-11. Protect young plants from frost. Best flowering in full sun.
  • Spanish Tamarind — warmth, sun, drainage, patience, collector interest. USDA Zone 9-11. USDA Zone 10-11, possibly warm Zone 9b in protected microclimates. Protect from frost, especially young plants.
  • Miracle Fruit — warmth, humidity, acidic soil, filtered light, protect from frost. Best in containers. USDA Zone 10-11. Cold hardy only to about 40°F — bring it in well before first frost, not after.

Can you grow them in pots?

Yes. With the standard warning: a pot is not magic. Use a large container, fast-draining soil, full sun where the plant wants it, regular feeding with Green Magic conrolled-release fertilizer every 6 months and Sunshine Boosters - safe to use with every watering. Apply a bit of pruning when things get out of hand.

Smokey: A pot is just a smaller universe.
Sunshine: A pot is a drainage system with ambitions.

📅June gardening reality check

June is a good time to establish tropical and subtropical plants. The soil is warm, the days are long, and actively growing plants will take root faster than they would in cooler months.

👉 A few things to keep in mind:

  • Containers dry out fast even when rain increases. Check them. Don't assume rain did the job.
  • Don't let pots sit in standing water. Root rot is quiet until it isn't.
  • Feed actively growing plants. They are working hard and they need the input. We recommend Green Magic controlled release fertilizer during active growth (twice a year) and Sunshine Boosters for spray and daily watering year around.

    📚 More about fertilizers from our garden Blog

  • Watch new growth for pests. Tender leaves are the first target.
  • Prune lightly to shape if needed, but don't do heavy cutting in peak heat. Save that for after flowering or early in the season.
  • Mulch around in-ground plants to hold moisture, but keep mulch away from the trunk.

🌠 The stars don't care? Grow anyway!

Maybe the stars do not care whether your garden is a Gemini garden. Maybe olive trees are not receiving transmissions from Mercury. But a garden full of fruit, fragrance, flowers, and strange little stories is still a very good idea.

Smokey: That is the first reasonable conclusion in this entire article.
Sunshine: Second. The donut research was also important.

Happy Gemini gardening season from all of us!

How to make leaves green?

Q: I purchased several plants from you and they all arrived in great shape. The Wrightia is very large and vigorous but some leaves are yellowish. How can I improve that look? Any special fertilizer?

A: Wrightias are very showy and beautiful plants, although sometimes they are susceptible to leaf chlorosis which in other words is iron deficiency, especially during wet rainy weather. It is not harmful to the plant and can be corrected with microelement applications. Use Microelements once a week to correct the iron deficiency that usually goes away within a month. Then maintain plants health with monthly applications. It is beneficial to use microelements in combination with regular applications of health boosting fertilizer.

Recommended boosters and microelement supplements:

Pink N Good Daily Plant Food - Flower Booster
Tropical Allure - Smart-Release Booster
SUNSHINE SuperFood - plant booster
SUNSHINE-Greenleaf

See SUNSHINE Boosters page for the complete list of plant boosters.

Avocado, Lychee and Mango setting fruit... give them some FOOD!

Q: Do I need to fertilize tropical fruit when they set fruit?

A: It is traditionally believed that mango and other tropical fruit shouldn't be fertilized during fruiting period. It is true to an extent: you don't want fruit to burst from fast excessive growing. Instead, try to feed fruit trees wisely, because they still need proper nutrition to produce flowers and fruit.
Our spring specials of Lychee, Avocado and Mango are full of buds and some already set tiny fruit (see examples on the photo). Here is the feeding plan for these plants once you receive your mail order:
1) Once received the plant, pot it into container size of the root ball and let establish for couple weeks. Use SUNSHINE-E to help the plant recover from shipping stress and establish root system.
2) Apply SUNSHINE-Honey right before flowering, and next time at setting fruit, to provide sweeter and bigger fruit, eliminate fruit cracks and help resist fungus and other fruit diseases.
3) Use balanced granulated fertilizer, 1 tsp per each gallon of soil. Apply once a month during Spring-Summer season. This gives the plant balanced macro-elements (NPK) necessary for overall plant health. Do not use on fruit trees fertilizers with high Nitrogen content.
4) Apply SUNSHINE SuperFood micro-element booster to keep fruit trees vigorous, develop strong root system and avoid deficiencies.
5) In case of signs of chlorosis (yellowing leaves with darker veins), give the tree SUNSHINE-GreenLeaf and watch the leaves turning green quickly.
After harvesting, don't forget to make another treatment of SUNSHINE-Honey as a preparation for the next year flowering and fruiting season.
