Cold protection for tropical plants

greenhouse and cold protection covers on tropical plants

Pushing the limits of tropical gardening

The year is almost over but the winter is not. This Christmas weekend at our Sebring B-farm we had it down to 30F. As a tropical gardener, winter can be challenging, especially if you grow plants outside of tropical zones.

To protect your garden from the cold, consider the following:

1. Monitor freeze watches and be prepared to take action if necessary.
2. Create temporary structures like mini-greenhouses using PVC pipes, carport frames, or bamboo sticks to support covers.
3. Use covers such as frost cloth, cardboard boxes, blankets, and bed sheets.
4. Use Christmas lights and other heating elements, including propane heaters, to keep plants warm.
5. Add a layer of heavy mulch around plant trunks to protect them from the cold.
6. Apply plant boosters that improve cold hardiness, such as Sunshine Epi, Sunshine-Si, and Sunshine Superfood.

At TopTropicals B-Farm, we sprayed our plants with a special cold hardiness treatment Sunshine-Si and covered and wrapped everything we could. We also moved cold sensitive species inside greenhouses. All of our plants are looking great and happy!

How to improve plant cold hardiness?

Pland cold hardiness depends on several factors, including:

  1. genetics of specific species
  2. maturity of the plant, size of root system, stems and branches
  3. plant health and vigor which is supported by proper nutrition program and adding special plant hormones.

    While 1) and 2) may be out of our control, the 3rd factor is something that can be easily improved! It is important to feed plants during the season of active growth on regular basis by applying macro- and micro- elements. Liquid fertilizers and especially natural plant food like Sunshine Boosters can be applied year around to keep plants healthy and strong.


Besides the routine fertilizing program, just a few applications of special plant hormones can increase tropical plant hardiness big time! Before the cold is coming, spray your plants with these 3 magic potions and they will gain a few degrees in low temperature tolerance! It is recommended to make 2-3 applications.

Hoa Mai - for good luck!

Ochna integerrima (thomasiana)

What is the yellow flower that brings good luck on Vietnamese New Year (Tet) Celebration? Why is it called Mickey Mouse Plant?

The most celebrated flower in Vietnam, Ochna integerrima, called in Vietnam Hoa Mai or Mai Vang, blooms profusely on the occasion of Tet, the Vietnamese New Year. Commonly known as Yellow Mai Flower (Hoa Mai literally means "yellow blossoms"), this plant is considered the quintessential symbol of Spring. In Southern Vietnam, Hoa Mai are some of the first plants to flower.
This plant is a must for exotic plant collection. It is a rather slow growing, medium size shrub that can be trained into miniature tree. In winter the plant is covered with pretty bright yellow flowers, believed to bring good luck and prosperity. They are followed by cute shiny black berries on bright red sepals that resemble the face of Mickey Mouse.

The plant is easy to grow and relatively cold hardy to light freeze. Start fertilizing your Hoa Moa plant right now through the Winter to encourage early blooms. Luckily, we have a perfect bloom booster liquid fertilizer that is safe to use year around, including Winter months: Sunshine Boosters MegaFlor!

Lunar year 2023 will be a year of the Cat on the Vietnamese zodiac, from January 22nd, 2023 to February 9th, 2024. Cat is the fourth sign in Vietnamese Zodiac, taking place of the Rabbit in Chinese Zodiac.

Add a little Sunshine
to keep your plants looking their best

By Ed Jones, the Booster Guy

Mango leaves before and after Sunshine Boosters application

...Just like people, a little sunshine goes a long way in keeping them happy. It is usually easier to keep a plant healthy than it is to fix it when it is not well. Proper plant nutrition is often times the issue. The good news is that it is easy to keep your plants looking good by following proper nutrition practices...
...Feeding your plants with micronutrients that they just don't get in regular fertilizers can prevent deficiencies. Let's get started on a regular program of using foliar sprays to help keep your plants looking their best...
We recommend using three products in combination - the Complete SUNSHINE Microelement Supplement Kit that consists of:

- Sunshine Superfood
- Sunshine Epi
- Sunshine Power-Si

How often do I need to treat my plants?

We are recommending a foliar spray once per week to maintain optimal health conditions. This is based on recent studies done in Ukraine by the scientist who invented Sunshine Boosters products...
Continue reading to see an easy treatment schedule that will provide your plants with:
- Increased photosynthetic activity
- Increased insect and disease resistance
- Reduced mineral toxicity
- Improvement of nutrient imbalance
- Enhanced drought and frost tolerance
- Enhanced plant growth

Fertilizing in Fall:
Plants need food too!

Sunshine boosters products collage

Q: I know that I am not supposed to fertilize plants in winter. But I just bought several ground orchids from you, they are blooming now and I wonder if I can give them some food to support their bloom energy? When should I do the last application of fertilizer? I will keep them in a sun room during Winter until Spring.

A: Traditionally, end of October to November is the time when we give the last dose of fertilizer to our tropical plants. Liquid fertilizers, and especially amino-acid based Sunshine Boosters, are safe to apply year around. This means, you can continue feeding your plants with Sunshine Boosters through the Winter without risk of over-feeding or burning roots. Why?
The answer is very simple: even with their metabolism slowed down in Winter, plants will use all that food.
Sunshine Boosters have special mild formulas that are scientifically designed and based on Amino Acids. Plants will use all essential elements from the solution as needed.
Liquid fertilizer is diluted in water, and will be applied only when you water the plant. During Winter, water needs are lowered = watering times are less frequent, with less amount of water = the plants will get less water and less fertilizer accordingly.

Importance of micro elements
in combination with plant food during winter

Keep in mind that feeding your plants regularly during Winter will help to avoid "winter chlorosis" and other deficiency problems. So called "cool-temperature-induced chlorosis" (CTIC) is especially common in Spring on young, actively growing leaves. Unless chlorosis is prevented by micro-element applications, affected leaves may remain in this condition for the rest of the growing season.

Make sure to select proper type of fertilizer for your over-wintering plants. We have special formulas for foliage, flowering plants, fruit trees, young seedlings, even for for orchids and bromeliads. Check out our selection!

Guava, the easiest container fruit tree

Guava fruit on a branch

Grow Your Own Food

Guava is one of the most popular and well-known tropical fruit because it is so tasty, sweet, juicy and flavorful! Many people are familiar with it because of the large number of products made from this aromatic fruit. But very few people know that Guava tree culture is very easy and this plant can fruit in a pot right away. Guava tree start blooming and producing fruit as small as 1 gal pot size. It can be kept in compact shape, responds well to pruning, stays bushy and grows very fast. It is a perfect container fruit tree or a specimen for a tropical garden of any size.
Upon ripening, the fruit becomes soft and juicy. It may be eaten fresh, made into a juice or nectar contain fruit pulp, or made into preserves, jam, jelly, or paste. A distinctive, savory-fresh aroma of fruit is thermo-stable, thus survives processing. The guava is an excellent source of vitamins C and A.
The plant is relatively cold hardy. Our young trees, 3 months after being planted in the ground were exposed to a short period of freeze last winter (mid-20's) but they grew back without significant damage. Try to keep Guava cold-protected for the first winter, then it will be much hardier once established.
Guavas are fast growers and heavy feeders, and benefit from regular applications of fertilizer. Make sure to get some Sunshine Boosters fertilizer: Sunshine C-Cibus - Crop Booster, and feed them your round.

What tree will fruit indoors?

Fruit trees for indoor containers

Q: I love your tropical fruit selection and I wish I lived in a warmer climate. Is there any fruit tree that can be happy indoors during winter and have fruit? I am not expecting a big crop but it would be fun to have a small piece of tropics at home. I don't have much gardening experience, can you suggest something easy for a start?

A: Several tropical fruit trees can be grown indoors, in pots, providing bright light that is necessary for flowering and setting fruit. Among them are many varieties of Bananas, Guavas, Annonas and tropical Cherries - these can be easily maintained in containers. Even dwarf varieties of Avocado and Mango are good candidates for indoor culture. You can bring containers indoors for winter and take outside into full sun during warm months so your plants can store lots of energy in Summer.
