Q: Can you make my yard bigger and prevent it from freezing?
A:
Yes, we can make your backyard bigger by adding a 3rd dimension - trees as a upper level, shrubs as a second level, vines in between, low growing perennials below them. Add ground covers and potted plants as separate specimens in between in-ground planted trees and shrubs. One more separate dimension is orchids and other epiphytes that happily grow on the trees. This multi-level structure will allow you not only collect so many plants, but also maintain them in a natural environment, similar to how they grow in a wild.
As far as preventing from freezing - it depends. You can use greenhouse, cover plants, create microclimate under large canopies, etc. Some tropical plants are tolerant to light frost, once established. If it gets below freezing in your area for more than a few hours, and especially if you have numerous nights with frost throughout winter, we recommend to keep plants in pots (BTW, this way you save space and can collect even more!). Pots can be moved to protected area during cold nights. The more established the tree, the more chances to survive colder temperatures. You may also use propane heaters during cold nights.
We also use plant booster SUNSHINE boosters to increase plants cold tolerance.
Cold protection is a lengthy subject. Here is some more information on cold protection.
Also, we recommend to check out our magazine Tropical Treasures (about pushing the limits of tropical gardening) for a detailed article on cold protection.

Overwintering Adeniums outside of tropics
Q: We bought several adenium plants from you. We are moving to the Denver area of Colorado. How can we make sure the plants survive? Should we use a green house?
A: Adeniums are perfect container plants, and house plants. They can be easily grown outside of tropical climate. During winter, Adeniums drop leaves and go into dormancy which makes it easy to keep these plants in a dormant stage in a warm location of your house, or possibly even in well-lit spot of garage (with a window), with temperatures above 50-60F.
Here in South Florida, during time of cold, when chances of freeze are high, we move our own Adenium collection into lanai, with plastic sheet protection around lanai.
In colder climates, Adeniums can be kept indoors as house plants during winter. There are some requirements/tips for you:
- Temperature. Move Adeniums indoors when temperature starts dropping below 45F.
- SUNSHINE. Use SUNSHINE boosters to improve cold resistance of Adeniums, and essure healthy plant throughout winter. SUNSHINE-BC

Ten common greenhouse mistakes and how to avoid them
Greenhouse with tropical plants
🏠 Ten common greenhouse mistakes and how to avoid them
1. Overwatering
It's easy to overwater in a controlled environment. Many greenhouse plants need less water than you think. Overwatering can lead to root rot, yellowing leaves, and fungal issues. Monitor soil moisture regularly and adjust watering based on the plant type, season, and current weather conditions.
2. Not enough light
Don’t block too much light - plants need full-spectrum light to thrive. Most greenhouse plants require as much light as possible to ensure healthy, vigorous growth. Lack of light causes leggy, weak plants and increases the risk of disease, pests, and fungal problems.
3. Too much of sun and heat
Greenhouses with plastic covers can trap intense heat, and during sunny afternoons, plants may get “cooked”. Direct sunlight can quickly overheat and damage foliage. Use shade cloth during the hottest months or to protect light-sensitive plants and prevent heat stress.
4. Overcrowding plants
Packing in too many plants reduces airflow, creating ideal conditions for disease and pest outbreaks. Give each plant enough space to breathe, grow, and receive light. Proper spacing also makes pest control and maintenance easier.
5. Poor ventilation
Lack of airflow leads to overheating, humidity buildup, fungal disease, and weak growth. Use fans, roof vents, or roll-up sides to improve circulation and maintain healthy growing conditions.
6. Skipping pest inspections
Greenhouses can trap pests in an ideal environment. Check plants regularly for aphids, spider mites, whiteflies, and fungus. Use systemic insecticides or organic treatments like neem oil at the first sign of trouble.
7. No consistent schedule
Inconsistent watering, feeding, and lighting can stress your plants and reduce productivity. Set a simple routine, and monitor conditions daily - even a quick walkthrough helps catch problems early.
8. Neglecting temperature and humidity control
Temperature and humidity can fluctuate dramatically between day and night. Use a thermometer (preferably with max/min memory) and a hygrometer to track conditions. Install heaters, shade cloth, misting systems, or dehumidifiers as needed.
Modern WiFi-based sensors that monitor temperature and humidity 24/7 are convenient tools - you can keep tabs on your greenhouse right from your smartphone.
9. Recycling old soil
Avoid reusing soil from plants that died, as it may harbor root diseases or pests. Always use fresh, high-quality soil for new plantings. Don't cut corners - healthy soil is key to healthy plants.
10. Dirty tools, containers, and covers
Reusing dirty pots or tools spreads disease. Clean and disinfect containers, trays, and tools regularly. Use a diluted bleach solution to clean clear plastic or ground covers if they show mold or algae buildup.

What plants are good to order in Winter?
Photo above: Christmas time in Ukraine (left) and Florida (right)
Q: Are there any tropical plants that will do well if I order them in Winter? We just bought a house in New Jersey with a large sunroom, and I can't wait to fill it with tropical beauties! Should I wait until Spring, or do you have something for a Winter start?
A: This is indeed a very good question, as many tropical plant collectors grow their treasures outside the tropics. The short answer is - yes! You can start filling your tropical sunroom any time of the year, but some plants are easier to deal with in Winter than others. Below are some guidelines.
Winter bloomers today, left to right: Jatropha, Champaka, Brunfelsia, Calliandra, Leonotis.
1. Plants that prefer Winter shipping to avoid overheating stress:
- All plants with lush foliage such as Philodendrons, Medinilla
- Trees with fine feathery leaves such as Moringa, Jacaranda, Poinciana
- Some fruit trees sensitive to overheating during shipping: Papaya, Stawberry Tree, Starfruit (Carambola), Bilimbi.
2. Subtropical plants that are relatively cold hardy
- Fruit trees:
Loquats, Olives, Avocados, Tropical Cherries: Eugenia, Malpighia, Noni (more cold
hardy than you may think),
Canistel.
- Flowering trees: Champaka, Tabebuia.
- All Bananas

plants
3. Winter-dormant and/or deciduous plants: Adeniums, Plumerias, Gingers, Sugar Apple
, Peaches and
Plums, June Plum and Hog Plum.
See all deciduous/winter dormant plants.
4. Orchids, including Ground Orchids.
5. Winter flowers. Keep in mind that many tropical plants are
winter bloomers, and their flowering is most profuse in Winter months, so you
can enjoy the blooms right away:
Dombeya,
Thunbergia,
Gloxinia, Brunfelsia, Calliandra, Tibouchina, Barleria, Leonotis, Clerodendrums, Chinese Hat (Holmskioldia).
See all Winter bloomers.

6. Winter plant care. During Winter the daylight is shorter and temperatures are
cooler.
- Reduce watering
- Use only liquid amino-acid based fertilizer Sunshine Boosters (safe to use year around)
- Monitor insects.
7. Shipping in Winter. We ship year around. However, if it gets below freezing in your area, you may use FedEx Hold location, they are temperature controlled so you don't have to worry about a box being dropped off at your cold porch outside.
8. A note for mild climate residents. Most tropical plants can be planted in the ground year around. Some ultra-tropical tender species such Chocolate tree, Ylang Ylang, or small size Mango trees can be grown in pots until Spring and planted out once chances of cold spell are gone. Until then, they can be moved indoors for cold nights.
Think outside the box and bring tropical paradise indoors during the time when we need warmth the most! Tropical plants will brighten your short winter days and help you to have truly HAPPY HOLIDAYS!

How to move plants from indoors to outdoors
Q: When moving my tropical plant collection outside in the garden, what do I need to know to get them adjusted to this change?
A: As a tropical plant gardener, it's important
to assess the temperatures outside before moving your plants outdoors. Most
tropical plants thrive in sustained temperatures above 60F.
Moving your plants outside during the summer creates optimal growing
conditions for sun-loving plants, providing them with more light and warmth than
they can ever get inside. This active time of growth, along with the outdoor
conditions of humidity, heat, sunlight, and natural day length, gives the plant
a chance to experience growth in an outdoor environment, making for a much
stronger plant.
However, be aware of sun burn. Direct sunlight can burn patches of
white or brown on the surface of the tender leaves, so it's best to move your
plants outside by hardening them off first. Gradually increase the amount of
direct sunlight they receive over several days before moving them into full
sun.
It's also a good time to prune your plants and repot them if needed,
providing better aeration to the root system. But avoid root pruning as it
can make your plant susceptible to disease and shock.
Overall, moving your tropical plants outside encourages their natural bloom
cycle and provides extra vigor for the upcoming indoor season. However, be
aware that you may have to deal with insects when you bring your plants
back inside in the fall, so use preventive sprays like Sunshine NoBug before bringing them back inside. Leaf drop is
also common when plants come back inside, so make sure to provide a well-lit
location.
When moving plants outside, it's important to provide them with proper
nutrients through fertilization. Outdoor conditions can deplete the soil
of essential nutrients, so giving your plants a boost of fertilizer before
moving them outside can help them acclimate to their new environment. Apply Sunshine Boosters
with every watering, include micro-elements and bio stimulants to boost their immune system.
